Optimization of Development Strategies and Injection-Production Parameters in a Fractured-Vuggy Carbonate Reservoir by Considering the Effect of Karst Patterns: Taking C Oilfield in the Tarim Basin as an Example

Energies
The spatial structural characteristics of fractured-vuggy units vary greatly in different karst patterns, which significantly influence the study of remaining oil distribution patterns in ultra-deep fractured-vuggy reservoirs and the determination of the

Study on Interference Testing of Fractured-Vuggy Carbonate Reservoirs [PDF]

Proceedings of the Advances in Materials, Machinery, Electrical Engineering (AMMEE 2017), 2017
Along with the development of oil and gas fields, geological condition and well pattern arrangement are getting complicated. More and more domestic and foreign experts have paid attention to the study of the interference testing to assess the connectivity between wells and solve the reservoir parameters.

A New Model for Predicting Flow in Fractured-Vuggy Carbonate Reservoirs under Pseudosteady State Condition

Geofluids, 2021
For constant rate production of a single well in a closed boundary fractured-vuggy carbonate reservoir, when the pressure wave propagates to the reservoir boundaries, boundary-dominated flow occurs, and the transient flow period ends, the reservoir will ...

Analysis of the Influencing Factors on the Extraction of Residual Oil through the Gel Foam Flooding of Underground Reservoirs in the Tahe Oilfield [PDF]

Gels, 2023
Fractured-vuggy reservoirs are mainly composed of three types: underground rivers, vugs, and fractured-vuggy structures. Based on the similarity criterion, a 3D model can truly reflect the characteristics of the multi-scale space of a fractured-vuggy ...
