... locations with no aboveground casing were surveyed for methane flux from the soil. Recent large-scale development of oil and gas from low-permeability unconventional formations (e.g., shales, tight sands, and coal seams) has raised concern about potential environmental effects. Production from...

... minor intercalations of limestone and dolomite but no volcanic components or known fossils. The series is probably 30,000 feet or more thick. It lies unconformably on a basement of earlier Precambrian granitic and gneissic rocks, and on the northwest side of the mountains it is overlain by the Cochran...

... to reduce carbon dioxide (CO 2 ) emissions. One promising approach is CO 2 capture and permanent storage in deep geologic formations, such as depleted oil and gas reservoirs, unminable coal seams, and deep brine-containing (saline) formations. However, successful implementation of geologic storage projects...

The results show that the magnitude of horizontal displacement increases over time, but the location of the maximum deformation does not. Because the boundary conditions and formation properties were more close to reality...
