Evaluation of gas production from multiple coal seams: A simulation study and economics

, 2018
Gas production from multiple coal seams has become common practice in many coal basins around the world. Although gas production rates are typically enhanced, the economic viability of such practice is not well studied.

Study on the best time of refracturing for Hancheng coal seam

Meikuang Anquan
The old wells in Hancheng Block face the problem of production decline after long-term exploitation, and need to be re-fractured to form new fractures to communicate with CBM rich areas, so as to achieve stable CBM production. Due to the small difference

Permeability reduction effect and correction for low-permeability tight sandstone reservoirs under bound water saturation

Shiyou shiyan dizhi
Tight sandstone reservoirs with low-permeability under formation conditions are highly prone to bound water saturation, and the permeability of dried samples obtained by standard methods can not accurately reflect the reservoir properties.
