... 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...

Besides, a complex 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...

... 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 are collected downhole, along with gauge...

... Abstract Computation of seismic-wave traveltimes is used in seismic imaging procedures such as Kirchhoff migration. For realistic applications, one has to precompute large traveltime tables (for all sources, receivers, and imaging points). This implies massive computations as well as storage...

... 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...

Even in this day and age, operators and company men sometimes inadvertently play a "dance" of gas intrusion and migration vs. mud...

... Summary The main objective of this work is to understand, by analytical and numerical study, how permeability retardation interacts with capillary barrier trapping to cause accumulation as CO 2 migrates upward in saline aquifers during geological sequestration. The study is of one...

... construction methods, especially casing and cementing practices for the protection of fresh water aquifers, have been reviewed in these three basins. The wells in the three basins were classified based on coverage of water and hydrocarbon zones as well as age. The assessment confirms that natural gas migration...
