  3. 3. 1 EXECUTIVE SUMMARYData managers in information-intensive scientific industries such as petroleum and gas exploration andproduction (E&P) understand the challenges that their rapidly growing datastores pose. Poor access to thehigh-quality, complete data they need to make informed decisions can cost millions of dollars. Many E&Pgeoscientists spend far too much of their time identifying, locating, and obtaining data they need for theirmission-critical analyses. This paper examines these challenges and then explores technology advancesthat now enable disk-based archiving to complement tape-based solutions. In doing so it helps addressthese challenges. The paper then examines the range of solutions from NetApp and Interica that enableE&P companies to leverage these advances. Finally, it summarizes the potential benefits ofthis approach.2 CHALLENGESA large percentage of data storage budgets in E&P operations are devoted to archiving for seismic storage,processing, and interpretation. Every dollar saved on these critical yet passive requirements could beredirected to proactive computing. The latter includes improving data access for seismic processing andinterpretation application for better reservoir characterization. This can facilitate real-time well operationsmodeling or global collaboration, which ultimately helps reduce risk and decrease cycle times.Tape technology has long been the archival mainstay for E&P companies and will continue to be a requisitepart of the storage hierarchy for many organizations for years to come, simply because of the vast amount oflegacy data. Yet today, some forward-thinking companies are looking at active archiving (near-line or onlinearchiving). They are evolving toward disk-based archiving solutions that can address growing datamanagement challenges associated with tape-only solutions.At the core of this trend is the inability of tape to effectively fulfill the active archiving role and the slowpace of data location, access, and recovery. (Active archives are those performed for storage managementreasons and that may be needed back online within a shorter term of one to two years.) In addition to theselimitations, the tape medium cannot ensure integrity of data over time and requires periodic tape remasteringat high cost, unless a robust archiving solution is in play that automates the latter.Recent cost analyses between online storage and near-line storage technologies, such as tape-basedsystems, show that online storage can be more cost effective than tape-based solutions over the lifetime ofthe seismic data. As technological advances in disk storage densities increase and effective deduplicationand compression technologies become available, these new online disk-based solutions are becoming morecost effective.STORAGE VOLUME AND RETENTIONSeismic information continues to grow at staggering rates. This digital tidal wave includes new pre- andpoststack volumes as well as derivative attribute volumes. The challenge is magnified by requirements tosupport higher-fidelity subsurface imaging and enhanced interpretation and visualization technologies thatcan utilize increasingly larger data sets.Geoscientists may use many different software applications to analyze this data, each of which generatesresults for storage. Individual files generated may be as large as multiple GBs, and these tools may generatethousands or even tens of thousands of files per project. E&P workgroups may juggle dozens of projects,each with this large set of files. And data retention times for this staggering amount of data are the life ofthe assets. Hence, E&P companies face high data storage costs and the need to scale their solutions fromterabytes to petabytes for rapid data growth.3 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  4. 4. DATA REMASTERING AND SYSTEM OBSOLESCENCEOver the last decade, tape technology evolutions have included DLT to super DLT, AIT to AIT 1-5, LTO toLTO 1-4, and 3590 to 3590E, 3592, TS1120, TS1130. During the same period, tape operating systems andapplications have evolved. In addition, tape deteriorates over time and may be subject to physical damage.For these reasons, companies are forced to periodically remaster or copy these tapes every three to fiveyears. The deterioration of tapes during storage and the remastering process is not only expensive but alsocreates many opportunities for errors to creep into the data. During each remastering project, some of thetapes are not readable, and therefore some or all of the data from these tapes is lost.Remastering from large legacy tape holdings can require person-years of exacting work and can costmillions of dollars. For example, one national oil company completed a project to make prestack datapublicly available. This involved remastering more than 500,000 tapes (9-track, 21-track, and 3,480cartridges), which took over three years to accomplish.Conversely, over the last decade, methods of accessing networked disk storage via CIFS or NFS havenot changed substantially. Hence, networked disk storage has proven to be more stable than tape-basedstorage, with minimal migration complexity or cost. As a result, networked disk storage can reduce oreliminate remastering costs and data loss.DATA CORRUPTIONPrecise, complete seismic data supports timely, informed decision making. Conversely, corrupted or incompletedata can impair decision makers. Magnetic tape is a fragile medium that is highly susceptible to thegeneration of errors by improper care and handling. More often than not, tape errors go unnoticed until thedata is needed, because there is no practical means to verify the integrity of the tape media and its data asthey age. There are countless stories in which tape recoveries have failed. The tape itself is intact, but theattempt to read and recover data is unsuccessful.By comparison, disk storage systems provide protection against failed disks utilizing RAID technology.These systems safeguard against data corruption through the use of data checksum and can proactivelynotify data storage administrators of impending failures.DATA RECOVERY SPEEDThe pace of recovery of data, either due to corruption, accidental deletion, or disaster, is also an importantconsideration. When a geoscientist loses a key data volume due to corruption or accidental deletion, datashould be recoverable in minutes, not days, to maximize productivity and efficient use of field assets. Yetdata recovery from tape is lengthy (hours, days, or even weeks), complex, and costly. Restoring data fromtape can also introduce risk due to the human intervention required.The inability to locate and restore project files quickly can incur financial losses or lead to missed opportunitiesfor the company. For example, if a decision that involves archived data analysis is needed for an offshoredrilling rig, indecision can cost a company as much as $500,000 per day in rig costs (typically called―nonproductive time‖). Traditionally, to restore a project, geoscientists were forced to wait until data centrallyoff-loaded in warehouse storage was retrieved—a process that could take days or weeks. Hence, decisionmakers were faced with the dilemma of waiting too long for the correct data or making the decision withinadequate data.Disk-based online storage solutions provide technologies that enable rapid, reliable data access in the caseof catastrophic failure or simply data loss. Already used today in business applications such as e-mail andfinancial systems, these technologies are now extended to seismic data.4 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  5. 5. DISTRIBUTED DATAAs E&P geoscientists gather and analyze data, they produce a variety of data subsets using a varietyof applications. In addition to the industry-specific, sophisticated analysis tools, personnel also storeinformation in the form of mainstream office productivity tools. Analyzed by different users at different times,this data and results are often stored across multiple systems and locations across the enterprise. Subpartsof the data may be archived off site at one time or another. Yet at some time in the future, all of this relevantproject data may need to be assembled in one location for further analysis. This raises the need for amethod of storing the data for rapid, complete access.3 COST COMPARISON: TAPE VERSUS DISK 1A study commissioned by NetApp and conducted by Oliver Wyman in 2006 and updated in 2008revealed that disk storage can be considerably less expensive than tape backup alternatives. While thisstudy focused on backup solutions, NetApp has seen similar potential benefits to disk-based solutions inarchiving applications.The study interviewed data managers using tape systems and data managers using disk-to-disk solutionsto determine the difference in costs based on three cost components: Product acquisition and ongoing vendor costs Direct internal costs Cost of lost productivity because of downtimeOverall, the study found that in a system with 30TB of storage, typical backup rotations, and four remoteoffices, disk-based storage provided a 39% cost advantage over tape-based systems.Even in organizations that consider only the up-front capital and ongoing vendor costs such as support andmaintenance for a backup purchase and ignore ongoing IT operation costs, including power, cooling, floorspace, and system administration, the advantage of disk-based solutions over tape was 14%. When all threecost components were considered, disk-based storage systems were found to be 48–54% less expensivethan a tape-based solution of similar capacity and size over a typical backup product lifecycle.Data managers focus on the ongoing costs of managing backup environments. Seventy percent of respondentsindicated that they rely on a total cost analysis, either based on internal sources or from a third party, whenmaking IT purchase decisions.When costs associated with ongoing labor and business activities are included in the analysis, the overalltotal cost story changes significantly: Disk-based storage becomes 70-75% less expensive than tapesolutions. The primary cost advantage is through lower direct internal costs, mainly labor. Respondentsfound, on average, a fourfold reduction in systems management time compared to tape environments,with some participants reporting even higher gains in labor efficiency.4 TECHNOLOGY ENABLERSA variety of technologies now enable disk-based storage to complement or, in some instances, replacetape-based archiving in E&P applications. Not all of these technologies can be used together in allsituations. However, consideration of each enabler allows implementation of a disk archiving systemthat meets the needs and policies of each specific business.1 ―Total Cost Comparison of Back-Up Technologies: IT Decision-Maker Perspectives on NetApp SnapVault Disk to Disk Versus Traditional Tape-Based Backup Solutions.‖Oliver Wyman, January 2008.5 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  6. 6. BETTER MANAGEMENT AND CONTROL OF DATAProject-based archiving involves grouping E&P business data into ―projects.‖ The data can includestructured, semistructured, and unstructured data—all linked by relevance to a particular project. Thisapproach can address storage, archival, and access of a wide range of data. The key is to preserve therelationship of distributed data to the project so that the data can be reinstantiated without external datarequirements.Within this project-based archiving framework, it is useful to examine how data can be better managed andcontrolled using disk-based software. This software can provide—or complement features in the disk thatprovide—the following capabilities: Better data compression Deduplication advancements Metadata and data management for discovery, deletion, disposition Data encryption for security Improved reliability Data-class storage managementDATA COMPRESSIONData compression technology for disk storage has come a long way. Today, lossless compression solutionssignificantly reduce the storage requirements for both pre- and poststack seismic data, without introducingdata integrity issues. Over the last several years, compression technologies have evolved using industrystandards. They achieve compression rates of 35–45% on SEG-Y data (see Figure 1). By deployingcompression technology in conjunction with disk-based seismic data storage, the density of storage isgreatly improved, providing savings in pure disk space, power, and air conditioning requirements as anadded benefit compared to traditional disk-based storage.Figure 1) Storage capacity saved using digital storage with lossless compression technology.Courtesy: Halliburton6 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  7. 7. DEDUPLICATIONData deduplication reduces the amount of data required to be physically stored by eliminating redundantinformation and replacing subsequent iterations of it with a pointer to the original. Deduplication ratios varygreatly according to the type of data being processed. Data that contains primarily unique information, suchas seismic files, contains very little redundancy and delivers poor deduplication ratios. However, data thatcontains significant amounts of repeated information delivers the highest levels of deduplication, typicallyincreasing capacity by 30–70%. For example, geoscientists and other users typically begin data analysiswith E&P applications by copying files from an existing project to begin a new ―project‖ and make changes tothe data. Deduplication of files like these, which contain significant repeated information, is especially helpfulfor project-based E&P archival.METADATA AND DATA MANAGEMENTOver the lifetime of a typical archive, knowledge of who interpreted the project, location of the project, aswell as the important horizons, faults, and well information that helped define the prospect fade over time,and may be lost. This information about the project (metadata) is critical to locating the data again in thefuture. A proper archiving system is needed to allow collection of this metadata. Once the metadata is inplace and associated with the archive, the archiving software enables users to search for the archive usingthe metadata that describes it. In this way, old and potentially valuable archives can be quantified withoutthe need to first restore and reinstantiate them. This saves time and production disk space.DATA ENCRYPTION FOR SECURITYCompanies must resolve the trade-off of added security versus cost to determine whether to encrypt bothdata at rest and data delivered to users. An important consideration is whether encryption is needed toprotect E&P data from internal or external threats, or both. Encryption policies are best specified in corporatesecurity policies.IMPROVED RELIABILITYA RAID 6 implementation prevents data loss when two disk drives fail. This enables use of drives thatprovide economical storage density, such as low-cost SATA (Serial ATA) disks, for seismic data storage,while also providing the needed data protection. SATA drive capacities are expected to increase rapidly inthe future. In addition, the disk storage system actively reports disk failure. No such technology exists toreport a bad data block on tape as it sits in storage.DATA CLASS STORAGE MANAGEMENTTraditionally, E&P companies have archived data according to the type of data (e.g., field seismic data,prestack data, poststack data, well logs, and so on). A more useful way to archive data is to use a tieredstorage solution in which data is classified and archived according to the need for the data, or patterns of itsusage. This enables access to data as a function of likely use or need. For example, data can be classifiedaccording to classes that respond to milestone events such as divestiture of an asset, tabling of an asset, orinvestigation of another area near the asset. The timing of use, number of users, types of uses, and otherparameters can also be used to classify data. This means that recently used data, data used by many, dataused in support of recent events, and so forth can be classified as ―hot storage‖ in an active archive. Datanot used for some time, rarely used, used in support of older events, and so forth can be placed in ―coldstorage.‖ And, of course, these classes can be made as granular as needed.7 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  8. 8. 5 NETAPP AND INTERICA SOLUTIONSInterica offers two solutions to address these challenges: PARS and SmartMove.INTERICA PARSThe Project Archive and Retrieval System (PARS) archives and restores structured, semistructured, andunstructured data from file systems, databases, and applications (see Figure 2). Specifically constructed tomanage large data sets, Interica has further tailored the system to accommodate the particular needs of theE&P industry during its 15 years of use in this vertical. Using the system, users can group relevant data (andcustomizable metadata) from any source. They can also specify where PARS is to archive information,verify modified data against the original, search for archives based on the metadata, and more. A policy ®framework plus an Oracle Database allow the entry and extraction of metadata. The user interface providespoint-and-click access to management features, including, of course, archive and restore. ® ®Administrators can integrate PARS with NIS and Microsoft Active Directory (via LDAP) to manage userauthentication and access control. They can also implement PARS without significant change to existing ITinfrastructure, due to the system’s out-of-band architecture. The PARS Migrator extension uses a project-based approach to automatically move files and data sets based on company policy-based criteria. PARScan be deeply integrated with mainstream exploration geotechnical applications such as LandMark’sSeisWorks, OpenWorks, and CDA; Schlumberger’s GeoFrame and Petrel; Seismic Micro-Technology’sSMT Kingdom; and many others. Similarly, PARS can be integrated with various storage systems.Figure 2) Interica’s Project Archive and Retrieval System archives and retrieves structured and unstructured datafrom file systems and applications.

  9. 9. INTERICA SMARTMOVESmartMove is a cross-platform tiered storage management application (see Figure 3). It provides discoveryof data by name, owner, size, and time. The application allows construction and implementation ofautomated file-movement policies. The data movements include copy, move, and migrate (i.e., move andcreate a link in the source file location pointing to the file on the destination storage.) Verification checks aremade during file movement to provide data integrity.SmartMove enables E&P storage administrators to regain control of spiraling data growth by providingtools to classify unstructured data and migration policies that can be tailored to the environment. SmartMovedoes not attempt to assume control of existing IT environments or insert itself between users and their data.Instead, SmartMove migrates data to more cost-effective storage using open protocols (CIFS, NFS). Itmaintains data accessibility using standard OS links and by retaining file and directory structures. Whenthese migrations are complete, users access their data without any intervention by SmartMove.Figure 3) Interica’s SmartMove is a cross-platform tiered storage management application. (Graphic provided byInterica.)NETAPP STORAGE PLATFORMNetApp’s storage systems provide simultaneous support for all protocols—Fibre Channel SAN, IP SAN,NFS, and CIFS—in combination with Fibre Channel, SAS, or SATA disk with the ability to selectively utilizeadditional capabilities, including data permanence and encryption. The result is that E&P organizationscan standardize on a single architecture for all archive and compliance initiatives that can be tailored tomeet the needs for scale, cost, and performance. Fundamentally, the same architecture that delivers highperformance and reliability for volume interpretation and enterprise-class applications, including Microsoft ®Exchange, Oracle, and SAP , can be utilized to deliver low-cost, massively scalable archival and complianceinitiative storage solutions for the same applications. Having a single set of software, tools, and processessimplifies the complex world of enterprise data management. A single process for activities such asinstallation, provisioning, mirroring, and upgrading is used throughout the entire NetApp storage productline, lowering administrative costs and making it easier to deploy new capabilities across all tiers of storage.Unifying storage and data management software and processes reduces the complexity of data ownership,enables the ability to adapt to changing business conditions without interruption, and results in lower totalcost of ownership (TCO).9 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  10. 10. NETAPP INTEGRATED DATA PROTECTION ®The NetApp Unified Storage Architecture also includes an embedded set of data protection servicesthat simplify the process of protecting against site outages and data loss. Called NetApp Integrated Data ®Protection, these services are tightly integrated within the NetApp Data ONTAP operating system andcan be enabled in minutes for rapid, easy implementation within any E&P environment. Integrated DataProtection services include: ™ Snapshot copies that provide a local, point-in-time image of the archive that is created in seconds Compliance locking that prevents data from being modified Disaster recovery that replicates the archive to a remote location for system and site level recovery; NetApp leverages embedded network compression to reduce network utilization up to 70%, accelerating DR and reducing network costs Replication-based backup that creates a remote, block-level incremental backup of the archive in minutes and reduces storage requirements up to 90% Storage clustering that stretches up to 100 km and is designed for zero data loss and zero downtimeNETAPP EXTENDED CAPABILITIESNetApp offers a single, complete product infrastructure that seamlessly integrates with key enterpriseapplications that drive the current generation of mission-critical enterprise data for archive and compliance.With NetApp, archive and compliance functions such as data classification and migration, data permanence,data security, and data discovery all integrate with the core platform, extending its capabilities. The ability toselectively apply these capabilities to any data set provides E&P organizations with the ability to meet anyparticular data management requirement (see Figure 5).NETAPP SOLUTIONS ®NetApp solutions include NetApp NearStore and NetApp DataFort.NetApp NearStore protection software provides E&P data protection and retention applications such asdisaster recovery, archival, compliant retention, and content storage. A disk-based secondary storagedevice for enterprise applications NearStore complements and improves existing tape archiving and dataprotection schemes. NearStore provides economical storage and rapid disk-based access to reference datato meet business and legal requirements. In addition, with a lower cost of acquisition and TCO than primarystorage and better performance than tape, NearStore is a proven solution for organization whose multisitereplication programs require an economical, high-capacity storage device to be located remotely.NetApp deduplication is a fundamental component of NetApp’s core operating architecture—Data ONTAP.NetApp deduplication can be used broadly across many E&P applications, including primary and archivaldata. By eliminating redundant data objects and referencing just the original object, NetApp deduplicationcombines the benefits of granularity, performance, and resiliency to provide a significant advantage in therace to provide for ever-increasing storage capacity demands. Compression can complement deduplicationand provide additional savings, especially on data that does not deduplicate well, such as geoseismic data(see Figure 4). The result is 1) reduced initial storage acquisition costs or longer intervals between storagecapacity upgrades, and 2) the ability to store more data per storage unit or retain online data for longerperiods of time.10 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  11. 11. Figure 4) Deduplication complements compression to reduce storage requirements.Networked storage speeds access to information, but it can also leave data vulnerable. Firewalls andintrusion-prevention systems can secure assets at the perimeter, but data at the storage core can beexposed to both internal and external attacks. NetApp DataFort Security Systems provide securitythroughout the entire lifecycle of regulated and sensitive data for multiple heterogeneous storage systemswithout disrupting applications, clients, servers, or user workflow. NetApp DataFort systems combine secureaccess controls, authentication, storage hardware-based encryption, and secure logging to protect storeddata. E&P administrators can deploy inline or network-attached storage to reap security advantages withoutimpacting user workflow. NetApp DataFort fits seamlessly into existing storage environments, supportingCIFS, NFS, IP SAN, FC disk, FC tape, and SCSI protocols. E&P companies can protect data both at restand in flight with encryption certified by the National Institute for Standards and Technology, even if ITmanagement is outsourced.Figure 5) NetApp comprehensive data protection capabilities in the E&P environment11 Challenges and Best Practices for Storing/Archiving Data in the Petroleum and Gas Exploration and Production Industry
  12. 12. 6 POTENTIAL CUSTOMER BENEFITSAdvanced disk-based solutions can enable better-informed decision making using the latest data all inone place. They can enable E&P users to identify, locate, and retrieve data quickly, accelerating mission-critical decision making, reducing field costs, and improving utilization of field assets. At the same time, thesolutions can improve geophysicist productivity due to easier access to data anywhere and anytime. Thesame technologies can also accelerate data recovery in the event of data loss, corruption, or disaster.Advanced disk-based solutions can enable more efficient completion of asset sales, including transfer ofdigital assets. They can reduce the cost of transcription and remastering of tapes due to the transfer ofsome archiving to disk. This can also enable ―platform protection‖—avoiding obsolescence of data formats,systems, operating systems, and applications. This benefit, as well as improved data integrity, can reduceIT costs.Looking forward, the solutions can provide flexibility and scalability to meet continued data growth andanalysis needs. They provide an outsourcing option that offers choice for firms seeking to outsource dataarchiving functions.7 CONCLUSIONSDisk-based archiving/storage can now cost-effectively complement tape-based archival in the E&P industry.Advances in both hardware and software technology drive this evolution. NetApp and Interica havepartnered to provide a range of solutions, including NearStore, NetApp DataFort, PARS, and SmartMove,to enable their customers to take advantage of this trend. The result for E&P adopters of this technology isbetter-informed, more rapid decision making, lower IT costs, and improved use of field assets. The solutionsalso provide platform protection and offer flexibility and scalability for the future.8 FOR MORE INFORMATIONABOUT INTERICAInterica is the new force in E&P data management, delivering integrity, control, access and efficiency to dataowners and users in Oil and Gas, across the globe.
