Effects of parent well spacing on the poroelastic behaviors in the infill zone in shale oil reservoirs: A case study in Jimsar Shale Oil, China

Energy Science &Engineering, Volume 10, Issue 4, Page 1043-1054, April 2022., 2022
The effect of parent well spacing on the poroelastic changes in the infill zone is not monotonic. Tight spacings lead to decreased breakdown pressure and decreased production potential. Loose spacings result in slightly increased breakdown pressure, while the production potential is preserved.

Occurrence, Genesis, and Significance of Analcime in Fine‐Grained Sedimentary Rocks

Geofluids, Volume 2022, Issue 1, 2022., 2022
Natural analcime, an aluminosilicate mineral with multiple genetic mechanisms, widely occurs in fine‐grained sedimentary reservoirs rich in oil and gas. Researchers have discussed the source and formation mechanism of reservoirs and the influence of morphology formation, occurrence characteristics associated with minerals, geochemical data, and Si/Al ...

Study on Pressure Characteristics of Disturbed Wells due to Interwell Fracturing Interference and Its Application in Small Well Spacing Fracturing

Geofluids, Volume 2022, Issue 1, 2022., 2022
In order to maximize the production of unconventional oil and gas reservoirs, the well spacing has been shrinking continuously. Thus, the interwell fracturing interference usually occurs, which brings some problems affecting the fracturing efficiency.

Fracturing and production analysis of the efficacy of hydraulic fracture stage reduction in the improvement of cost‐effectiveness in shale oil development: A case study of Jimsar shale oil, China

Energy Science &Engineering, Volume 9, Issue 9, Page 1337-1348, September 2021., 2021
The use of hydraulic fracture stage reduction can mitigate fracturing interferences and lead to more uniform hydraulic fracture growths. Consequently, more uniform productions from individual fractures can be obtained, indicating more uniformed depleted SRVs.
