“Subsurface integrity” Identifying, risking, and maintaining subsurface integrity is of critical importance to a variety of geologic subsurface operations including geothermal, oil and gas production (conventional, unconventional, fractured crystalline, heavy-oil fields), mining, natural gas storage, and sequestration of CO2 and hazardous waste. Predicting and mitigating out-of-zone fluid migration includes but goes beyond maintaining well integrity: it relies on technical understanding of top and fault seals, reservoir and overburden deformation, production/injection-induced stress changes, reservoir management, completions design and engineering, hydraulic fracturing/height containment, wastewater disposal, induced seismicity/fracture reactivation, and reservoir monitoring (e.g., geodetic and downhole measurement and interpretation). Subsurface integrity excludes surface facilities and spill response but includes regulations regarding subsurface activities.

Fundamental Principles of Reservoir Engineering outlines the techniques required for the basic analysis of reservoirs prior to simulation. It reviews rock and fluid properties, reservoir statics, determination of original oil and gas in place by volumetrics and material balances, evaluation of drive mechanisms, fluid flow in porous media, aquifer influx, well testing, fluid distribution and displacement, and decline-curve analysis. #reservoirengineering #fluiddynamics #oilgasindustry #welltesting #reservoiranalysis #WeAreSPE #oilandgas #energybooks https://buff.ly/3W8CK53

🔔 Join us for our first Distinguished Lecturer presentation of the season on Tuesday, October 8th with speaker Dr. Leen Weijers! Our industry's innovation to successfully frac and produce from shale, the source rock for hydrocarbons, has dramatically changed global energy access and geopolitical balances. The North American shale industry has relentlessly pushed for a lower cost to bring a barrel of oil ($/bbl) or a cubic foot of natural gas ($/scf) to the surface. This reduction has greatly benefitted world energy consumers.   The dramatic reduction in this cost ration is sourced in two metrics. First, cost of drilling and completion has been cut in about half for shale wells over the last decade through efficiency gains and innovations in workflow. Second, well production has roughly doubled through a focus to increase both the extent and intensity of the created hydraulic fracture system.    This North American track record of innovation, operational learnings and engineering optimization contains lessons learned for other shale basins around the world. One idea members will take away from this presentation is that our industry is capable of wide-ranging and rapid innovation when free market forces are unleashed to produce the cheapest barrel possible.

🎯 Well Testing, Carbonate Reservoirs and Value of Information 🎯 Maximizing the Value of Information (VoI) in carbonate reservoir testing isn’t just about data collection—it’s about targeted, purposeful test design. The work by Jordan Mimoun and Fermin Fernandez-Ibañez, PhD emphasize that, in carbonate reservoirs, well-test objectives must be sharply defined to capture the true complexity of the subsurface. 🛠️ In carbonates with excess permeability, knowing whether to focus on matrix properties or non-matrix features is crucial. Tests designed to highlight deliverability in prolific zones may miss critical reservoir characterization details, while tests aimed solely at matrix properties might not fully capture a well’s production potential. By carefully selecting test intervals and strategies, operators can distinguish between matrix and non-matrix features, ensuring that VoI is maximized for each specific objective. 💡 This approach not only optimizes early field development but also prevents costly missteps down the line, where inadequate reservoir appraisal could otherwise lead to underperforming assets. Tailoring VoI to specific test goals is more than just best practice—it’s a competitive advantage. Figure: Impact of fault proximity on pressure transient and value of information. Left: A dipping normal fault intersects the lower section of a well. Because of inclination, the fault damage zone is located farther away from the well in the shallow well section. Right: Log-log plot for 3 well tests at three different depths with varying distance to the fault damage zone. From top to bottom: shallow test (distance to fault damage zone ~150 m), intermediate test (distance to fault damage zone ~50 m), and deep interval (well intersects fault damage zone).

💡 Reservoir geomechanics is the study of how mechanical properties of rock and fluid interactions affect the behavior of subsurface reservoirs. It involves understanding stress, strain, and deformation within the reservoir rock to predict and manage issues like subsidence, fracturing, and compaction during resource extraction. #PetroleumEngineering #OilAndGas #Energy #OilIndustry #GasIndustry #DrillingEngineering #UpstreamOilAndGas #DownstreamOilAndGas #EnergySector #OilField #EnergyInnovation #Hydrocarbons #OilAndGasExploration #EnergyEngineering #PetroleumGeology #ReservoirEngineering #EnergyResources #PetroleumIndustry #OilAndGasJobs #OilAndGasTechnology #oil #gas #welltest #industry #engineering #production #petroleum #fundamentals #OilAndGasSector #EnergyTransition #PetroleumProduction #EnergyManagement #PetroleumRefining #OilAndGasDrilling #EnergySolutions #OilAndGasField #PetroleumEngineeringLife #OilAndGasReservoirs #Sonatrach #aramco #OilAndGasInfrastructure #EnergyEfficiency #OilFieldServices #OilAndGasConsulting #OilAndGasSafety #EnergySustainability #OilAndGasMarkets #PetroleumTech #EnergyDevelopment #societyofpetroleumengineering #SPE #slb #Halliburton #reservoir #geomechanics #model

Reservoir Engineering Terms - plugging Understanding key concepts is crucial in reservoir engineering. When discussing plugging, it refers to particles larger than half of the pore space diameter. These particles serve a specific purpose - they plug at the sand face, ultimately acting as a fluid loss control agent. #ReservoirEngineering #OilandGas #EngineeringTerms

We will cover these topics in-depth from the basics to the latest developments and the technologies involved. There is also a lot of controversy about environmental concerns. The lack of knowledge is so severe that even some aspiring presidents are talking about banning fracking. How valid are these concerns surrounding the pollution of our drinking water and cause of earthquakes by fracking? It is important for professionals in the Oil & Gas industry to have an in-depth understanding of such risks and concerns rather than believe hearsay. #Fracking #HydraulicFracturing #OilAndGas #Energy #Technology #Sustainability #Environment #Science #Engineering #Innovation #Petroleum #NaturalGas #GlobalEnergy

Someone asked me for some information on geoscience and reservoir engineering. I decided to take this out of a textbook I have written but have not published. This textbook was written as I would attend meetings and learn about various things. I would go back to my desk and research what I did not know. It was how I learned. My exposure to reservoir engineering was through 4Ds that bp was acquiring in the North Sea to ensure gas was not coming out of solution and forming gas caps. The 4Ds were used to determine if injection wells would be used to increase the pressure-keeping the gas in solution.
