Energy Science &Engineering, Volume 11, Issue 10, Page 3332-3343, October 2023., 2023 Three‐dimensional geomechanical model is established to determine the distribution of the in situ stress field and fault activity distribution. Abstract To improve the development efficiency of ultradeep fault‐controlled carbonate reservoirs, the deformation and connectivity mechanism of fractures was revealed through large‐scale rock mechanical ...

Energy Science &Engineering, Volume 11, Issue 9, Page 3102-3118, September 2023., 2023 A hydro‐thermal‐mechanical‐chemical‐coupled model was developed to investigate the acidizing process with different geological conditions and operation parameters. The coupling effect of natural fractures and in situ stress was taken into account. Numerical results show that choosing proper operation parameters, such as reducing the acid injection rate,

Geofluids, Volume 2023, Issue 1, 2023., 2023 Stress sensitivity and the elastic outer boundary (EOB) condition have a great effect on the analysis of the characteristics of the fluid flow in a reservoir. When researchers analyzed the characteristics of the fluid flow, they have considered the stress sensitivity and the EOB condition separately but have not considered them simultaneously ...

Microgravity Monitoring in Fractured‐Vuggy Carbonate Reservoirs
Geofluids, Volume 2023, Issue 1, 2023., 2023 With the development of Tahe Oilfield entering the high water cut stage, gas channeling occurs in fractured‐vuggy system during nitrogen injection, resulting in some inefficient wells. To improve the development effect of gas flooding, how to define the distribution of fracture, vuggy, and remaining oil has become one of the urgent problems to be ...

Temperature Field Study of Offshore Heavy Oil Wellbore with Coiled Tubing Gas Lift‐Assisted Lifting
Geofluids, Volume 2023, Issue 1, 2023., 2023 Offshore heavy oil resources are abundant, but they have greater difficulty and higher costs compared to onshore extraction. When crude oil flows through the seawater section, the temperature of the crude oil decreases faster, making it susceptible to solidification in the wellbore and resulting in lower well production.

Research on the Depletion and Recovery Characteristics of Fault‐Karst Reservoirs
Geofluids, Volume 2022, Issue 1, 2022., 2022 A fractured‐vuggy carbonate reservoir is a special reservoir formed by long‐term physical, chemical, and geological processes. Its reserves are large in scale and widely distributed, showing the characteristics of free flow‐seepage coupling. Conventional simulation is usually simplified by equivalent permeability, which cannot reflect the actual ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 Because of the strong random distribution of fractures and caves, fault‐solution carbonate reservoirs exhibit significantly different flow mechanisms and development methods from conventional carbonate reservoirs. Natural elastic and edge‐bottom water flooding are the main processes for developing fault‐solution reservoirs.
