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

Displacement efficiency in the water flooding process in fracture–vuggy reservoirs

Journal of Petroleum Exploration and Production Technology, 2017
To determine how fracture–vuggy structure, pressure, and injection–production mode influence displacement efficiency in the water flooding process in fracture–vuggy reservoirs, two types of models were built based on the characteristic of such reservoir: two fracture models with different fracture apertures and two fracture–vuggy models with different ...

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 ...

Productivity Prediction of Fractured-Vuggy Reservoirs under Time-Varied Flow Rates and Bottom Hole Flow Pressures

Geofluids, 2022
Fracture-vuggy oil reservoirs contain micrometer-sized dissolved secondary pores, fractures, and meter-sized karst caves. Generally, the researches on the flow mechanism of fractured-vuggy reservoirs are based on the assumption of karst cave-fracture ...
