Several well-stimulation products and techniques have been seen to benefit well productivity from recent field trials and implementations in carbonate reservoirs, including simpler acid fluid systems, integrated work flows, and coiled-tubing bottomhole assemblies. The fourth industrial revolution is taking the oil and gas business by storm. Many companies have increased resources for big-data analytics and machine learning. Though no one sees physical oilfield services as in decline, development in these areas may take a back seat to artificial intelligence. This paper covers the staged field-development methodology, including analysis and evaluation of various development concepts, that enabled the company to optimize both completion design and artificial-lift selection, reducing downtime and lowering operating costs by nearly 50%.
For the upstream industry, where improvement in efficiency or production can drive significant financial results, there is no question that the size of the digital prize is huge. In this study, the authors use a quantitative seismic interpretation work flow (QSI) based on a rock-physics template in estimating the uncertainty of the geochemical properties of organic mudrocks of the Shublik formation of the Alaskan North Slope. This paper demonstrates how maintaining investment in high-quality 3D seismic during the last downturn, together with selective exploration, quality geoscience, application of new technologies, and efficiently maturing discoveries to early cash flow, was successful in sustaining future production. In this paper, the authors propose a least-squares Q migration (LSQM) method that combines the benefits of both LSM and Q prestack depth migration (QPSDM) to improve the amplitude fidelity and image resolution of seismic data. Happily, in this past year, we witnessed several examples of marriage between two themes—exciting technology advances and the recent economic downturn.
Duri Field in Indonesia is the largest active steamflood project in the world. The field produces 73,000 BOPD, and 10,000 optimization jobs are executed annually to support base production. The objective of this study was to look at factors that can affect a temperature log and steps that can be taken to improve temperature-measurement accuracy. This paper covers the staged field-development methodology, including analysis and evaluation of various development concepts, that enabled the company to optimize both completion design and artificial-lift selection, reducing downtime and lowering operating costs by nearly 50%. The First Eocene is a multibillion-barrel heavy-oil carbonate reservoir in the Wafra field, located in the Partitioned Zone between Saudi Arabia and Kuwait.
Autonomous Inflow Control Valve technology demonstrates significant benefits within first year. Saudi Arabia offers a seemingly bottomless supply of oil and an equally deep array of exploration challenges as well. The most recent hydrocarbon production boom is under way in the Middle East, and this time, the race is spilling into offshore waters. Landmark deal called most significant since 1979 peace treaty. This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
The good news is 95% of the oil companies in Texas are expected to survive 2020, which means there is a lot of bad news to endure. Can Regulators Move Fast Enough To Fix a Shattered Market? Texas Railroad commissioners recognize the battering Texas oil companies, and their workers, are taking, but will continue considering their options until 5 May. Even some free-market advocates are calling for regulators to step in and try to help pull them out of what feels like a chasm by setting production limits. As studies point to increased emissions, ExxonMobil is stepping up efforts to detect and mitigate methane release.
Carbon dioxide (CO2) waterless fracturing uses liquid CO2 to replace water as the fracturing fluid in reservoir stimulation. The continuity and reliability of the blender are key factors determining performance of the operation. The complete paper discusses an advanced matrix-stimulation work flow that brings reliability and flexibility to the acidizing of tight carbonate water injectors and has delivered injectivity improvements tight carbonate onshore reservoirs in the Middle East. The complete paper discusses a method of stimulating deep, high-temperature offshore wells by combining an efficient single-phase retarded acid (SPRA) system and an engineered, degradable, large-sized particulate and fiber-laden diverter (LPFD). Several well-stimulation products and techniques have been seen to benefit well productivity from recent field trials and implementations in carbonate reservoirs, including simpler acid fluid systems, integrated work flows, and coiled-tubing bottomhole assemblies.
What the industry needs at this stage is a willingness to work together, share best practices, conduct innovative research, and focus on disruptive technologies that lower cost of capture and make our operations more sustainable. The complete paper presents a large-scale work flow designed to take a vast amount of data into consideration. The work flow can be scaled for projects of any size, depending on the data available. Denbury Resources needs enhanced debt reduction. The company that does enhanced oil recovery using carbon dioxide it produces and transports has skipped a payment to creditors while it seeks a deal that would reduce its debts.
This paper outlines the value of 4D for reducing uncertainty in the range of history-matched models and improving the production forecast. This paper describes interpretation results of a 4D seismic-monitoring program in a challenging Middle East carbonate reservoir. Integrated surveillance is critical for understanding reservoir dynamics and improving field management. A key component of the surveillance is areal monitoring of subsurface changes by use of time-lapse geophysical surveys such as 4D seismic. In this paper, the authors propose a new method for time-lapse-seismic surveys focused on water-injector wells.
This paper presents an analysis of a CO2-foam-injection pilot in the Salt Creek Field, Natrona County, Wyoming. A carbon-dioxide (CO2) -foam enhanced-oil-recovery (EOR) pilot research program has been initiated to advance the technology of CO2 foam for mobility control in a heterogeneous carbonate reservoir. Aqueous foam has been demonstrated to have promise in conformance-control applications. This paper explores the foaming behavior of a CO2-soluble, cationic, amine-based surfactant. A growing chorus of suppliers, researchers, and service companies is persuading US operators to re-examine their use of slickwater in shale plays and consider displacing it with carbon dioxide and nitrogen.
The cement industry is exploring carbon capture technology to reduce its carbon footprint. Oil and gas extraction using water has opened up new hydrocarbon resources. However they can produce four times more salty water byproduct than oil. Desalination in shale gas and polymer-flood EOR remain niche markets for lowering cost and improving production. Nanotechnology has great potential to reduce cost, increase production, and even improve the sustainability of E&P operations.
