Modern oil and gas field management is increasingly reliant on detailed and precise 3D reservoir characterisation, and timely areal monitoring. Borehole seismic techniques bridge the gap between remote surface-seismic observations and downhole reservoir evaluation: Borehole seismic data provide intrinsically higher-resolution, higher-fidelity images than surface-seismic data in the vicinity of the wellbore, and unique access to properties of seismic wavefields to enhance surface-seismic imaging. With the advent of new, operationally-efficient very large wireline receiver arrays; fiber-optic recording using Distributed Acoustic Sensing (DAS); the crosswell seismic reflection technique, and advanced seismic imaging algorithms such as Reverse Time Migration, a new wave of borehole seismic technologies is revolutionizing 3D seismic reservoir characterization and on-demand reservoir surveillance. New borehole seismic technologies are providing deeper insights into static reservoir architecture and properties, and into dynamic reservoir performance for conventional water-flood production, EOR, and CO2 sequestration – in deepwater, unconventional, full-field, and low-footprint environments. This lecture will begin by illustrating the wide range of borehole seismic solutions for reservoir characterization and monitoring, using a diverse set of current- and recent case study examples – through which the audience will gain an understanding of the appropriate use of borehole seismic techniques for field development and management. The lecture will then focus on DAS, explaining how the technique works; its capability to deliver conventional borehole seismic solutions (with key advantages over geophones); then describing DAS’s dramatic impact on field monitoring applications and business-critical decisions. New and enhanced borehole seismic techniques – especially with DAS time-lapse monitoring – are ready to deliver critical reservoir management solutions for your fields.
This document summarizes a presentation on improving reservoir simulation modeling with seismic attributes. It discusses how seismic interpretation provides information on stratigraphy, facies distribution, and reservoir properties through attributes. Seismic attributes can help with horizon and fault interpretation when seismic signals are poor. They are also used for facies and property modeling to distribute lithology and properties between wells and in un-drilled areas. Integrating seismic attributes into reservoir modeling can significantly improve dynamic models, simulations, and production forecasts.
Shale development in the US has been ongoing for at least the last decade, and many lessons can be learned from the US experience to help prevent air emissions and aquifer contamination in future developments around the world. Media reports and films such as "Gasland" imply that shale development is widely polluting fresh water aquifers and the atmosphere, with a wide range of estimates of contamination. This lecture examines the risk of contamination of aquifers through wellbores, either by hydrocarbon migration or hydraulic fracturing operations, and is primarily based on a comprehensive three-year study funded by the US National Science Foundation examining nearly 18,000 wells drilled in the Wattenberg Field in Colorado, plus other relevant studies. In the midst of the Wattenberg field is heavy urban and agricultural development, with over 30,000 water wells interspersed with the oil and gas wells, resulting in a natural laboratory to measure aquifer contamination. Lessons learned have universal applications with clear relationships established between well construction methods in both conventional and unconventional wells and contamination risks.
This document summarizes a study on stormwater impacts to McVicar Creek. The study aimed to: identify impacts; characterize them through a stream assessment; identify 3 representative sites; pursue further research; and develop remediation recommendations. The initial assessment identified 3 sites - Court Street, Castlegreen, and County Fair - for further study. Additional data collection and stakeholder workshops were held. The workshops developed stormwater management objectives and site-specific recommendations. For Court Street, increased enforcement and education were recommended. For Castlegreen, investigating infrastructure and partnering with local groups. For County Fair, educating landowners and considering end-of-pipe solutions were recommended. The final recommendations emphasized objectives and further stakeholder
Extended-reach wells present difficult drilling challenges, which if inadequately understood and addressed can yield significant downside risks and extensive non-productive time (NPT). These challenges are mainly due to complex well designs that combine high-deviation and extended-reach wellbores with difficult geology and hostile environments. Understanding the challenges and developing solutions are important to deliver the well with the proper casing specifications for production purposes.
Geomechanically, due to their long reaches and high deviations, borehole instability and lost circulations are particularly dominant in the overburden shale sections of extended-reach and horizontal wells. However, a good understanding of the rock failure mechanisms and an innovative use of the wellbore strengthening techniques can mitigate these geomechanical challenges through integration with good drilling practices such as efficient equivalent circulating density (ECD) management and effective hole-cleaning strategies. In addition, the long open-hole exposure typically experienced in these wells can cause chemical, thermal and/or fluid penetration issues that can further complicate the difficult drilling conditions. These secondary influences further stress the importance of incorporating geomechanical understanding in drilling fluids formulation.
This presentation focuses on the geomechanical challenges of drilling extended-reach wells. It highlights the need to integrate geomechanical solutions with appropriate drilling practices, particularly solutions based on good understanding of the intricate relationship between borehole stability, lost circulation, ECD, hole cleaning and bottom-hole assembly (BHA) optimizations in overcoming the drilling performance limiters. A case history will be presented as an example.
The document outlines a training module on extended wet detention basins and extended detention wetlands, including an agenda that covers an overview and definitions, design examples, a design activity, and considerations for implementation, operations and maintenance, vegetation, and lessons learned. The training is sponsored by MARC and presented by engineers from CDM to review best practices for these stormwater management techniques.
Combining Solar Technology with Sustained and Controlled Release Reactants - ...Lindsay Swearingen
The document describes a groundwater remediation project that combined sustained release reactant technology using potassium permanganate encapsulated in SOCORE cylinders with a solar-powered recirculation system. This created a low-cost, low-maintenance reactive zone to intercept a dissolved phase contaminant plume. The system cost under $75,000 to install in 2013 and has operated for over 2.5 years, with contaminant concentrations decreasing and the first recharge event costing under $10,000 in 2016.
Dwindling availability of water, combined with increases and competition in demand, climate change impacts, trends toward true cost water pricing, among other “drivers,” necessitates that urban water planning incorporate consideration of strategies for use, conservation, and reuse of treated wastewater and stormwater. Three innovative initiatives will be discussed as illustrations of “win-win” approaches that achieve effective water management (urban water security/sustainability) while facilitating economic development.

The SPE Foundation and member donations primarily fund the SPE Distinguished Lecturer Program. Companies also support the program by allowing employees to serve as lecturers. Additional support comes from AIME. The program provides 30 minute presentations on reservoir topics. Robert Hawkes will present on hydraulic fracture flowback dynamics, discussing load fluid recovery and its implications for long term production. His presentation will cover laboratory observations, field data, and diagnostic tools to understand flowback mechanisms and estimate ultimate load fluid recovery.
In order to determine a field’s hydrocarbon in place it is necessary to model the distribution of fluids throughout the reservoir. A water saturation vs. height (Swh) function provides this for the reservoir model. A good Swh function ensures the three independent sources of fluid distribution data are consistent. These being the core, formation pressure and electrical log data. The Swh function must be simple to apply, especially in reservoirs where it is difficult to map permeability or where there appears to be multiple contacts. It must accurately upscale the log and core derived water saturations to the reservoir model cell sizes.
This presentation clarifies the often misunderstood definitions for the free-water-level, transition zone and irreducible water saturation. Using capillary pressure theory and the concept of fractals, a practical Swh function is derived. Logs and core data from eleven fields, with very different porosity and permeability characteristics, depositional environments and geological age are compared. This study demonstrated how this Swh function is independent of permeability and litho-facies type and accurately describes the reservoir fluid distribution.
The shape of the Swh function shows that of the transition zone is related more to pore geometry rather than porosity or permeability alone. Consequently, this Swh function gives insights into a reservoir’s quality as determined by its pore architecture. A number of case studies are presented showing the excellent match between the function and well data. The function makes an accurate prediction of water saturations even in wells where the resistivity log was not run due to well conditions. The function defines the free water level, the hydrocarbon to water contact, net reservoir and the irreducible water saturation for the reservoir model. The fractal function provides a simple way to quality control electrical log and core data and justifies using core plug sized samples to model water saturations on the reservoir scale.

Since the inception of the partnership between TU and KCWA in 1998 through TU’s national Kettle Creek Home Rivers Initiative, numerous assessments (including hydrogeological studies and airborne remote sensing surveys) were conducted, and nine passive treatment systems, a land reclamation project, and a mine pool stabilization project have been completed.
The document discusses alternative dredging methods using mud conditioning to maintain navigable depths. It presents a case study from Emden where mud conditioning techniques kept sediments navigable, reducing maintenance dredging needs. The key techniques discussed are:
1. Artificially liquefying consolidated mud through controlled shear stress to maintain fluid mud layers.
2. The "KSN" or "Keep Sediments Navigable" method which periodically mixes mud layers to prevent consolidation without removing material.
3. Trials in Rotterdam demonstrated mud conditioning relocated sediments and increased navigable depths without dredging.

The SPE Distinguished Lecturer Program is funded primarily by the SPE Foundation through member donations and Offshore Europe. It allows industry professionals to serve as lecturers on topics like CO2 storage and CO2-EOR. Additional support is provided by AIME to further the program's educational mission.
The document discusses various techniques to reduce the environmental footprint of unconventional gas drilling operations, including:
1) Prototype small footprint drilling rigs, multi-well pad drilling, and coiled tubing drilling to minimize land disturbance.
2) Centralized fracturing to hydraulically fracture multiple wells from a single location.
3) Innovative water management techniques like constructed wetland systems to treat produced water on-site.
4) Developing an "EFD scorecard" to measure drilling technologies' performance on issues like air, water, and waste management.
The Dunmurry Wastewater Treatment Works (WwTW) located in Belfast underwent a £5.5 million upgrade to modernize its outdated systems and increase its capacity to 62,500 people equivalents. The upgrade included installing new fine bubble aeration tanks, a 31m diameter final settlement tank, increased sludge handling capacity, and automation to improve treatment and meet stricter consent standards for nutrients. The upgrade works were completed in 2012 and ensured the plant could reliably treat wastewater from growing populations in the area well into the future.
A refinery was dealing with increasing biological sludge levels that were reducing retention time and efficiency in their wastewater system. A company used sonar mapping every 45 days to track the results of a biological sludge treatment program over 90 days. The program reduced sludge levels across all three ponds by 26 inches, increasing total water capacity by over 1 million gallons. This helped double the retention time and removed over 5,000 cubic yards of sludge biologically without dredging or disposal costs.
Because of the extent of AMD impacts in Pennsylvania, the Commonwealth has become, by necessity, a leader in the development of passive treatment technology. People from around the world travel to Pennsylvania to learn about the successes we have collectively achieved, including the installation of over 300 passive treatment systems. In recent years, the capabilities of passive systems to treat highly acidic mine discharges with high concentrations of dissolved metals has been questioned. It is important to remember that with any treatment system, whether passive or active, proper design, suitable land characteristics, quality construction, proper maintenance and sufficient funding, are needed to provide a long-term, cost-effective approach for watershed restoration. This presentation will provide mini case studies that demonstrate, by example, that passive systems can and are effectively treating acidic, high-metal, discharges in Pennsylvania.

This document summarizes a site-wide groundwater feasibility study being conducted by the EPA for the Middlefield-Ellis-Whisman Superfund site. It outlines alternatives being considered to accelerate groundwater cleanup, including expanding existing pump and treatment, in situ bioremediation and chemical oxidation of high concentration areas, and monitored natural attenuation. The alternatives aim to reduce contaminant levels and minimize long-term vapor intrusion risks. The EPA is evaluating pilot tests and community input to inform the feasibility study and selection of final cleanup remedies.
This paper discusses optimization of hydrocarbon production in the Cerro Dragon oilfield in Argentina using latest formation evaluation and perforating technologies. It summarizes how nuclear magnetic resonance (NMR) logging helped identify different hydrocarbon types in reservoirs that conventional logs could not distinguish. A propellant-assisted perforating (PAP) method was proposed to optimize well productivity while maintaining safety. The PAP method uses oxidizer to create high pressures and mild fracturing near the wellbore. The paper focuses on applications of PAP in the San Jorge basin, including enhancing connectivity beyond damaged zones and near water contacts where hydraulic fracturing is not feasible.
This document summarizes the use of liquid curable resin (LCR) systems to control proppant flowback in hydraulic fracturing operations in Argentina. Various operators applied LCR either during initial fracturing treatments by coating proppant on-site, or as remedial treatments by injecting resin into existing fractures. LCR treatments helped stop proppant flowback while maintaining production rates, reducing cleanout costs compared to untreated wells. Lessons showed resin concentration and additive selection are important to maximize proppant pack strength and conductivity. Field results demonstrated LCR treatments effectively control solids flowback to optimize well productivity.

This project essentially looked at the stability of a deepened approach channel and examined the impact of the dredging and disposal for the scheme in support of a public planning hearing. The modelling used coupled MIKE 21 FM HD-SW-ST models as well as well as MIKE 21 and MIKE 3 FM HD and MT models.
In these times of low oil and gas prices, the drive to provide 'more for less' has never been greater. One key component in achieving this is the ability to accurately monitor the production rates along a wellbore and across a reservoir. Ideally a range of different measurements should be available on-demand from all points in all wells. Clearly conventional sensors such as downhole pressure and temperature gauges, flow meters, geophone arrays and production logging tools can provide part of the solution but the cost of all these different sensors limits their widespread deployment. Fibre-optic Distributed Acoustic Sensing, or DAS for short, is changing that. Using an optical fibre deployed in a cable from surface to the toe of a well DAS, often in combination with fibre-optic Distributed Temperature Sensing (DTS), provides a means of acquiring high resolution seismic, acoustic and temperature data at all points in real-time. Since the first downhole demonstrations of DAS technology in 2009 there has been rapid progress in developing the technology and applications, to the point where today it is being used to monitor the efficiency of hydraulic fracture treatments, provides continuous flow profiling across the entire wellbore and is used as a uniquely capable tool for borehole seismic acquisition. With optical fibre installed in your wells and DAS acquiring data, there is now the ability to cost effectively and continuously monitor wells and reservoirs to manage them in real-time in order to optimise production.

Case study Read the following case study and write your report about the project formotion
damage concepts in the field and state your final conclusion. Abstract The Ruba reservoir in the
Casanare region of Colombia is currently being appraised and developed. Cost effective
development of the reservoir will be dependent on applying optimum drilling and completion
practices. The purpose of this poster session is to provide a case study history for the approach
and evolution of the project as it pertains to attainine an improved understanding of fonnation
damage mechanisms. Introduction Background Ruba Field is located in the kithills, 150 miles
northeast of Africa. Light (>34* AP1) oil, gas and condensate in Ruba occur at drilling depths
which average 16000 ft . in an asymmetric hanging wall anticlinal trap 14 miles long and 3 miles
wide, formed during the Mioceneto-fiecent deformation. Top and lateral seals are provided by
marine mudstones of the Oligocene Carbonera Group, and support a hydrocarbon column of over
1600 ft . The region is tectonically stressed in the formations which overlay the Ruba reservoir.
Because of this, drilling conditions are ditficult with wellbore instability, mud losses, and stuck
pipe common. Geology and Mineralogy Over 50% of the reserves occur in Late Eocene Mirador
Fm sandstones, deposited in fluvial and shallow marine environments. Additional, deeper
reservoirs include fluvial and shallow marine Paleocene Barco Fm sandstones, and the shallow
marine Campanian Upper Guadalupe Sandstone Fm. Porosity in fuba is relatively low, and
averages 9% in the Mirador Fm . Good permeability is retained, however, because the reservoirs
are pure quartz-cemented quartz arenites, in which permeability-reducing authigenic clays and
carbonate cements are absent. Core and well test analysis indicate matrix permeability, not
fracture permeability, provides the high deliverability (> 12,000 BOPD) of Ruba wells.
Reservoir Fluids Ruba hydrocarbon phases exist in a near miscible, critical point state. Analysis
indicates very high liquids recoveries will be achieved using reinjection of produced gas. The
field will therefore be developed using reinjection of produced gas to maintain reservoir pressure
and vaporize residual liquids. The field contains significant volumes of hydrocarbon liquids and
large volumes of gas. Key Components of the Well Process Analyzed The study focuses on
evaluating the key phases within the well process that are known to influence mechanical skin
damage and corresponding well productivity. The phases analyzed include conceptual planning,
reservoir mud systems, wellbore constraints, mud losses, hardware constraints, perforating
parameters, kill pill designs, and completion brines. Drill Stem Testing Operations 16 drill stem
tests have been conducted for Ruba over the previous 2 years that are considered valid for
analyses and calculation of mechanical damage skin. The majority ( 7 out of 8 DSTs) of the data
anal.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

33. lessons learnt from DSSlessons learnt from DSS
• Application of hydrological modeling techniques are important in
planning of surface and ground water resources management in
Madhya Pradesh state.
• The regular monitoring of hydrological and meteorological data is
important for future water resources planning. The scientific
validation of data is equally important.
• The assessment of water availability and demand assessment need
to be carried out on regular basis to meet the various water use
demands in Wainganga basin
• The seasonal groundwater model developed for Dhuty RBC can
be used in groundwater planning and to predict how much
groundwater will be available at the end of May based on the
groundwater level at the end of October.

34. lesson learnt from DSSlesson learnt from DSS
• The reduction of water losses from Sanjay Sarovar canal,
Dhuty weir LBC and Dhuty weir RBC would result in increased
efficiency of the irrigation projects, additional water availability
for irrigation, reduction in demand deficit and increased
reliability of the system.
35. Issues Regarding DSSIssues Regarding DSS
• Change of Basic modeling software (Mike basin to Mike Hydro)
• Frequent change of DSS(P) version is not comfortable.
• DSS software for decision making and result projection requires the
knowledge of scripting programming which are difficult to perform.
