... In addition, a distributed fiber-optic sensing (DFOS) system is installed outside the tubing to capture the variations in acoustic energy during the migration and circulation of gas influxes. These sensors utilize optical fiber technology to map the physical fields acting on the fiber...

.... A static & dynamic model is created to capture the reservoir behavior, variations, and physics. As such, it is utilized to assess the field's effective storage capacity, reservoir injectivity, CO2 plume migration, pressure connection potential, CO2 breakthrough phenomena, and stimulation effectiveness...

... of an efficient solution when severe losses occur or for combined events with gas migration; the limited concentration and type of LCM not forming a solid, hard, compact, and impermeable structure that could penetrate the formation and develops compressibility greater than 500 psi helping to control gas migration...

... and aquifer pressure evolution enables understanding of the overall aquifer material balance. Finally, we consider implications of brine migration during and after long term CO 2 injection in unconfined aquifers. Experience in the petroleum industry with aquifer behavior include presence or lack of water...

... faulting system identified on the west side of the basin was modeled to preclude risks of CO 2 migration. The faulting system at the northwestern SJB was identified through well log stratigraphy. A near-vertical faulting system was mapped that may pose uncertainties to the sealing capacities...

... in its supercritical form. Under static conditions, the CO2 remained in its supercritical form and showed no migration in SOBM, making its detection more challenging than for a methane influx. Driller's method was applied while simulating circulating the CO2 influx. For both mud types, the model showed...

... Abstract Gas migration velocity impacts the planning of pressurized mud cap drilling (PMCD) as it plays a pivotal role in the selection of fluid volumes and logistics. A pilot-scale experimental investigation of gas migration under downhole conditions (up to 3,600 psi, 240°F) in water, oils...

... performed involving the injection of nitrogen kicks through a chemical injection line and also by bullheading down 2-7/8 inch tubing in both stagnant and circulating water. Variations in flow rate, kick size, and backpressure are investigated including gas migration during shut-in. DTS and DAS data...

... function) and allows building approximation that is more sophisticated: (4) h ( x ) = f Θ ( x ) , Abstract Computation of seismic-wave traveltimes is used in seismic imaging procedures such as Kirchhoff migration. For realistic applications, one has to precompute large...

... in Wolfcamp suggesting the migration of oil and gas from deeper (∼11,000 ft.) to shallower levels (4,000-6,000 ft.) in the same formation. Oil accumulation in Bone Spring is concentrated at the depths of 11,000-7,000 ft. with some intervals being more productive mimicking the alternating position of shaley...

...) distribution maps. Boundary condition trends and maps for heat flow (HF), sediment-water-interface-temperature (SWIT) and paleo-water depth (PWD) were created and calibrated to known present-day values. A 3D PSM model was simulated using Combined (combined Darcy+Inversion Percolation) migration...

... Abstract Fines migration is a commonly observed phenomenon in oil and gas wells, but often difficult to duplicate in the laboratory. A suite of labs tests was conducted to gauge the effect that different test conditions have on fines migration and to improve fines migration prediction through...

... Abstract Many deep water wells experience steep productivity declines. Some field observations indicate that this decline is partly attributed to fines migration effects. This paper presents a numerical workflow to simulate the effect of flow induced fines migration on production decline over...
