Symbiotic Combination and Accumulation of Coal Measure Gas in the Daning–Jixian Block, Eastern Margin of Ordos Basin, China

Energies, 2023
Coal measure gas resources, including coalbed methane (CBM), shale gas, and tight gas are abundant in the Daning–Jixian Block. The complexity of the source–reservoir–cap relationship in the coal measure strata leads to unclear symbiotic characteristics ...

Characteristics of In Situ Stress and Reservoir Pressure in Deep Coal Seams and Their Influences on Reservoir Depletion: A Field Case Study

Geofluids, Volume 2023, Issue 1, 2023., 2023
The production of coalbed methane resources is greatly dependent on the reservoir depletion process. To improve the depressurization efficiency of deep coalbed methane (DCBM) reservoirs, the fluid production characteristics and implications of in situ stress and reservoir pressure for reservoir depletion in the eastern margin of the Ordos Basin are ...

Study on Downhole Throttling Characteristics of High Water Content Gas

Geofluids, Volume 2022, Issue 1, 2022., 2022
In order not to hinder gas production, we usually hope that the bottom hole effusion can be discharged to the surface with high‐pressure natural gas. For the production data of high water content gas wells, the problems of insufficient water content and liquid‐carrying capacity affecting gas well production should be considered.
