Technology
Remote field data communications often involves multiple teams and vendors and automation systems require different wireless systems than traditional broadband internet systems. This presentation by Trevor Textor will help unravel the complexities and highlight the differences between automation traffic and traditional broadband traffic and how that might change the radios installed based on the circumstances. Also covered will be understanding optimal wireless frequencies, video communications (telecom as a utility), IT merging with automation (model differences between IT and engineering), financial impacts of a digital oilfield and how a “connected field” can deliver the dream of “just turn it on anywhere”. Telecom passive infrastructure and rural data communications outages will also be covered.

Understanding the Remote Field Data Communications Challenge Trevor Textor Project Manager, Rural IT & Telecom Consultant Principal, Textor Corp. -- Fostering “it just works” rural data communications systems that enable clients to focus on their core business -- www.textor.ca ca.linkedin.com/in/trevortextor
- 2. Agenda • Requirements-based frequency selection. • Impact of communications on the Oil & Gas industry. • Delivering services - silo vs. central planning. • Rural Deployments - IT & Telecom Engineering. • Design approach. • Telecom as a Digital Oilfield enabler.
- 3. Spectrum Determines Physical Characteristics No Frequency “Silver Bullet”
- 5. Frequency vs. Spectral Efficiency Spectral Efficiency Measures efficiency of a communication system measured in bits/hertz. Cooper’s Law The ability to transmit different radio communications at one time and in the same place has doubled every 30 months since 1895 (120 years).
- 6. Benefits of Improved Rural Communications Communications Safety Business Functionality Savings
- 7. Total Cost of Ownership (TCO) Telecom Utility TCO = Capital Costs + Operating Costs + Downtime Costs The cost effect of a telecom outage can vary from: • As little as ~$3K/day/site. • As much as millions per day.
- 8. Team Silos Multiple teams delivering telecommunications has negative impacts such as: • Taking the team away from its intended function. • Inefficient workarounds. • May not have telecom skills. • Lack of coordination results in: – Supply chain management problems. – Technology interaction issues.
- 9. The Need for a Central Coordinating Function Oil & Gas Business Cycle: • Oil & Gas investment is largest in the early stages. • Utilities leverage best results when introduced early.
- 10. IT Rural Communications Skill Deficiency • Urban communications = Rent services • Rural communications = Rent or Build? • Oil & Gas business clients expect IT to deliver. • Building is an engineering project, IT commissions services. This disconnect is a big problem.
- 11. The “Off the Shelf” Fallacy Passive vs. Active Components Total Cost of Communications = Passive 80-95% + Active 20-5% Passive = civil engineering works required to support telecommunications. – Towers, trenches, Conduits, cables, buildings – Fallacy is that towers can be “off the shelf” (no civil and telecom engineering required) Active = the actual electronic components that makes telecommunications happen.
- 12. Services Internet/Email/Voice/Video/911 Emergency Services Remote sensing, Monitoring & automation, Real time drilling, Intelligent completions, Visualization & modelling Active Components 5-20% (radios, routers, switches) Passive Components 80-95% (civil engineering works; towers, trenches, laying duct/cable)
- 13. Tower Placement & Size Matters Tower Design Type: “Off shelf” Requirements based Initial Cost: $30K $80K Well Cost: $2M $100K LMR Range: Limited Improved Future Proof? No: $80K new tower Yes Total: $2.1 M $0.2M Telemetry example of two tower design approaches
- 14. Piecemeal vs Utility System Design Piecemeal • One at a time design • Expensive • Complaints an indicator Utility System • Inter-site design • Better service overall • 3x cheaper • Capital payback: 1 – 3 yrs • Downtime reduced ~2.5 days/site/year
- 15. The Digital Oilfield • Formative study conducted in 2003 • Many improvements can be further enabled by a connected field (utility) – Covers Area of Interest – Committed resource – Full control (QoS)
- 16. Digital Oilfield Technology Improvements CERA estimated range of efficiencies: Improve hydrocarbon recovery: 1-7% Accelerate production: 1-6% Improve operating efficiency: 3-25% Reduce drilling cost: 5-15% Reduce downtime: 1-4% 5 main technology areas: Remote sensing Intelligent completions Monitoring & automation Real time drilling Visualization & modelling
- 17. A Connected Digital Oilfield Is Possible Petroleum Development Oman (45,000 sqr km) • Increased a mature oilfield’s production by 100K barrels/day. At $90/barrel this is $3.2 Billion/year in additional revenue within one year. • Reduced drilling & completion days to online from 39 days to 14 days. • 10 month payback.
- 18. Conclusion Six Misconceptions Dispelled… 1. There is no silver bullet - Radio frequency choice is determined by requirements. 2. Radios cannot be evaluated based on frequency; instead use Spectral Efficiency. 3. Radio equipment is not the final cost; include business impacts & lost opportunities (TCO).
- 19. Conclusion Six Misconceptions Dispelled… 4. Teams cannot effectively manage their communications needs; a coordinating function has cross-silo visibility and the ability to design holistically. 5. Civil engineering projects should not be “Off the Shelf”. Everybody wins when active and passive infrastructure is designed holistically as a utility. 6. A connected field is possible and recommended!

- There is no communication system silver bullet. Video is a bandwidth driver and use of it is beginning to go beyond security… everything visual can be sensed, tracked and discussed. E.g. is everyone wearing PPE? Collaboration requiring field visual and geographically disperse experts to resolve quickly. Once video is introduced, bandwidth usage expands at 50% CAGR (Doubles every 1.5 years). Note, Video for Oil & Gas is upload centric, not download centric as most internet services are delivered.

- 10 Commandments of Wireless Communications Since wireless is subject to considerable variables much of it can be opinion-based and subject to considerable debate. This author recommends that several experts come to an agreement on system design parameters however this is an excellent summary on the considerations for installing wireless systems (laws of physics, fade margin, decibel math, receive sensitivity, obstructions, curvature of the earth, etc.). http://www.bb-elec.com/Learning-Center/All-White-Papers/Wireless-Cellular/10-Commandments-of-Wireless-Communications.aspx Cooper’s Law Source: http://en.wikipedia.org/wiki/Cooper%27s_Law#Cooper.27s_Law Image Source: http://wcomm.ulsan.ac.kr/research/research.htm
- By itself, communications does not save money. Communications is an enabler. That is, it makes things possible. Its absence either prevents negative events from happening or increases the cost of doing business in terms of capital and time. Therefore, it is a utility, just like electricity.
- TCO represents true cost to Oil & Gas business since it measures business value. Telecommunications works best when it is intentionally designed as a system of different technologies working to address all the needs of the business. So how much does downtime cost the Oil & Gas industry? Here are some “what if” scenarios: What if the Operational Control Centers can’t see a plant? This scenario involves a call-out and causes a safety concern because of lack of visibility. What if no production information is reported? What if incident response is delayed? TCO helps to different telecom technologies, especially based on the need it addresses. The cost effect of a telecom outage can vary from: As little as $3K/day/site. This is the average cost to repair based on low energy prices and largely factors in call-outs and labor to repair. (operator call-out, IT, wireless rigging crew) To as much as Millions of dollars per day. The example I have for an impact of millions is Direct Transfer Trip. DTT was required for a substation powering all of the compressors in a region. DTT is an intelligent electrical management system to ensure the grid is stable. Each DTT node shares information with all of the other nodes. If the communications link goes down, DTT automatically shuts off the power due to lack of power quality visibility.

- This comment is in regards to mid-to-large size upstream oil & gas companies. Many smaller companies do not have the resources to get help. However, if mid-to-large upstream O&G companies have a strategy that also assists its subcontractors it would go a long way! After all, these companies are the authority in many remote areas.

- Capture whole cycle’s value by starting early. Intentional coordinated telecom design aligns to this need.

- “passive components” are the civil engineering works that allow active components to operate. What is important to notice is that 80-95% of the cost of the network is in this passive layer. These are things like towers, data centres, electrical systems and laying duct or fiber. It is important to note that these passive components do not involve IT but are engineering projects handled by Engineering, Procurement and Construction Management (EPCM / EPC) companies. These projects take anywhere from weeks to years to complete.
- Telemetry example of two tower designs and their direct economic impact (excludes indirect impacts, such as poor coverage, outages, poor performing services). Subsequent Well cost is based on small towers/masts at wells. With an improved LMR range there is less need for additional repeaters. LMR = Land Mobile Radio (push to talk - PTT) Telecom engineer / expert makes tower size recommendation based on radio frequency planning requirements for entire lifecycle of Oil & Gas. Each stage is then “ready to go” with no need to wait 3 months to a year for a tower build. Many times a tower build is a tower re-build, pushing up capital costs. In addition, if place right tower early, capture Oil & Gas’s main capital outlay and reduce communications costs immediately. It follows then, since passive assets are so critical to performance that more time, effort and expense should be spent here to yield the best return on investment on communications expenditures.
- To enable a successful brownfield evaluation, consider a System Design Approach which addresses all sites within a region and looks for economies of scale and location-based opportunities. This is contrasted by a piecemeal approach in which each site is considered one at a time.
- A multi-client study by IHS CERA in 2003 is often cited and describes the technologies that make up the digital oilfield of the future, also known as a smart oilfield. A connected field is required to implement many of these technologies. A connected field refers to a private communications system that covers the Oil & Gas firm’s area of interest with appropriate SLAs and committed information rates. Seminal study: The Digital Oilfield of the Future: Enabling Next Generation Reservoir Performance, IHS Cambridge Energy Research Associates, Inc., 2003. The study is obtained by purchase only from IHS CERA. It is not posted online due to the age of the study.

- I’m not an expert in any of these areas, but I was personally responsible for delivering the bad news to 100s of projects and business cases. That is, the rural communications system could not support the technology they wanted to implement and it would cost many times their project budget to make it so that it could. This effectively killed many promising projects. The question is, does lack of communications block full implementation of the many business cases required to fully implement a smart oilfield? How much money is on the table? It’s hard to put the published percentages into context. So, to illustrate the possible effects of a digital oilfield and its disruptive change using a large, publicly-traded company’s annual report I converted the percentages into dollar amounts. Let us assume that 50-70% of the technologies since 2003 have already been implemented successfully. The remaining digital oilfield changes could still translate to significant savings of $35M to $182M each year per upstream company. Conceivably, we’re talking about $350 Million to nearly $2 billion in operating savings and revenue increases in a decade per upstream company. The cost of such a connected field would be less than 1% of these figures. This then, is the final misconception to address. A connected field is entirely possible and inexpensive when compared to the business cost reduction and revenue increases it enables. Note: Most current real time drilling applications use satellite which is considered “near real time” due to the lags created by signals travelling 50K miles or 80K kms, the round-trip distance of a geosynchronous satellite. ========== Additional information from CERA: From CERA report who uses the term “Digital Oilfield of the Future” (DOFF): “Most of the DOFF’s impact will result from the use of five key technologies. • Real-time drilling. RTD enables petro professionals to monitor and direct the drilling of a well from a remote, centralized control room, using a combination of seismic, measurement/logging while drilling data, and steerable drilling assemblies. • Intelligent completions. The industry expects these new completion assemblies to isolate multiple producing horizons, incorporate controllable choke and valve assemblies, and enable continuous pressure and temperature monitoring. The goal is to modulate production across multiple producing horizons to control withdrawal/injection rates. This allows petro professionals to more effectively manage water influx, flood fronts, and near wellbore “coning” and to add operational flexibility in the face of mechanical problems. • 3D visualization and modeling. These tools will increasingly be used to create and represent complete asset characterizations to facilitate fuller understanding and cross team analysis. This will require better integration across a large set of disparate databases (including geological interpretations, well tracks, reservoir models and facility characterizations), analytical tools, and performance models. There is also considerable interest in more widespread use of multisite simultaneous work sessions—e.g., linking Aberdeen and Houston in real time. Additionally, combining 3D visualization technology with real-time operational data and information to track and control production and drilling operations will likely continue to expand. • Remote sensing. Advances in seismic, especially refinements of time-lapse technology, are leading to its growing use as a production management tool. The ability to resolve in-reservoir fluid phases (i.e., oil versus gas versus water) and flow barriers such as faults and stratigraphic discontinuities is essential for maximizing oil recovery from large, complex oil fields and for achieving the increased reserves outlined in the introduction. • Monitoring and control. This topic covers a wide range of applications, from basic SCADA systems for simple onshore gas wells to advanced, fully networked systems designed for demanding mission critical applications such as high-volume, high reliability floating production, storage, and off-loading (FPSO) operations. The focus is to increase the reliability, density, and accuracy of data capture from all surface facilities and to apply this same type of control/acquisition philosophy to downhole equipment. These improvements will increase automated data capture and distribution, thereby enabling remote, centralized monitoring and optimization. The objective is to reduce the number of field personnel and to raise production volumes.
- I use Petroleum Development Oman as an example since it is the largest and most complete adoption of a smart oilfield that I know about. In addition to being 45,000 sqr km, it has 200 active rigs & 90 trucks. ================== Additional Info on PDO: As of the end of 2013, Petroleum Development Oman field has: 6600 broadband connection points 52 base stations 13 Gbps total capacity, the equivalent of 500 connected homes or the bandwidth provided to a 4000 person office building 130,000 end devices Together it collects 36 times more data enabling more accurate and improved decisions. It delivers 4 Mbps anywhere within the field of coverage. Adoption of IHS CERA’s 2003 study’s recommendations and a connected field has enabled them to deploy technologies that: Increased a mature oilfield’s production by 100K barrels/day. At $90/barrel this is $3.2 Billion/year in additional revenue. Reduced drilling time from 39 to 14 days ($1M per drill saved). Saved $5M per-well cost (includes drilling and completions).
- A central coordinating function should be supported by executives (as champions), business development (budgeting) and engineering (civil projects). Did not touch on business and organizational models to further enable due to time.

- Here are some other factors to consider when comparing vendor’s radio products. Please note, this is not an exhaustive list. Receive sensitivity refers to how well the radio can hear; the smaller the number the better it hears. (e.g. -90 dBm is better than -64 dBm) Packets per second is a metric to measure the quality of the processor and memory in a networking device. Networking behaves like a traffic light. Based on the type of networking device, it may have to do additional operations on each vehicle that passes through the intersection. Each operation takes time. Modern radios do more than just store and forward. They now encrypt traffic, enforce quality of service and/or add trunking tags. As a simple rule of thumb, compare the packets per second of the device with no software features enabled to start as this is the maximum packets per second of the device. Also ask for acceptance testing results for radios that vendors make. Acceptance tests are the tests done in factories to prove what is written in the technical datasheets. Is it a Software defined radio (SDR)? SDR is moving out equipment refreshes from 5-7 years to 15-20 years since SDR radios can take a simple firmware upgrade for most feature improvements. Be wary of Class 1 / Div 2 radios. The certification requires less transmit power which translates to a link budget hit. Only have it if you need it.
- I often get asked, “why is Telecommunications not handling towers”? The short answer is because they don’t make enough money providing rural service. If Oil & Gas designs and/or builds towers, proving out a need, there is an emerging tower industry that owns towers as real estate and would be interested in owning the tower. There are many engineering considerations however to complete a successful match-up. But it is possible. =========== The top 3 tower companies listed on the New York Stock Exchange are: SBA Communications American Tower Crown Castle Collectively they own, lease and manage 95,000 towers and are worth $69 Billion. One of these top 3 companies, SBA, has moved into Canada. Canada, at present, has a very small passive asset marketplace to enable buyers and sellers of this crucial commodity. That is, it is very difficult to determine ownership and there is little support for enabling rentals. If one was implemented, it would be owned and managed by Industry Canada. Source: TowerXchange: http://www.towerxchange.com/the-art-of-tower-design/ TowerXchange is an open community for thought leaders in the emerging market tower industry. “We engage with the passive (and active) infrastructure market along two axes. On a horizontal axis we foster dialogue between MNOs, towers, investors and their advisers, accelerating to market investible, high quality telecoms infrastructure assets. On a vertical axis, we examine the impact of tower transactions on the product and service supply chain, from turnkey installation and O&M subcontractors to energy equipment, monitoring and management and static asset manufacturers.
