The Equivalent Numerical Simulation of Fractured-Vuggy Carbonate Reservoir

Applied Mechanics and Materials, 2011
The storage spaces of carbonate reservoir are complicated, matrix pores, vugs, fractures and large caves are coexistence. Traditional numerical simulation methods have harsh requirement for geology model and computing method, these methods are not suitable for carbonate reservoir.

Analysis Methods of Bottom Pressure for Fractured-Vuggy Reservoir

Advanced Materials Research, 2011
It’s difficult to measure bottom pressure in the fractured-vuggy reservoir, and measuring cost is usually high; In this paper, using the modified Beggs-Brill method, the variety of wellbore pressure has been calculated and analyzed. Results show that the variety of wellhead pressure is consistent with that of bottom pressure, and the variety of ...

Experimental Study on Fiber Balls for Bridging in Fractured-Vuggy Reservoir

SPE Journal, 2023
Summary For conventional particles used for conformance control in fractured-vuggy reservoirs, large-size particles easily plug the wellbore area but have difficulty plugging the zone far from the wellbore, while small-size particles easily move in depth.

A Method for Distinguishing the Effective Fractures in Fractured-Vuggy Reservoirs

Advanced Materials Research, 2012
In this paper, a combination of static and dynamic methods was used to identify effective fracture in Fractured-vuggy reservoir. An initial fracture model was established through the fuzzy neural network (FNN) and ant-tracking algorithm based on the static data (log and seismic data).

Two-Phase Modeling within Fractured Vuggy Reservoir

Mathematical Models and Computer Simulations, 2019
The paper is devoted to the mathematical modeling of flows within discrete fracture network systems, taking into account the fluid flow along vugs associated with fracture intersections. A mathematical model is described for a two-phase flow accounting for the flow exchange between fractures and vugs, as well as capillary and gravitational forces ...

A multiple-continuum model for simulating single-phase and multiphase flow in naturally fractured vuggy reservoirs

Journal of Petroleum Science and Engineering, 2011
The existence of vugs or cavities in naturally fractured reservoirs has long been observed. Even though these vugs are known for their large attribution to reserves of oil, natural gas, or groundwater, few quantitative investigations of fractured vuggy ...

Modeling the Depletion of Fractured Vuggy Carbonate Reservoir by Coupling Geomechanics with Reservoir Flow

SPE Reservoir Characterisation and Simulation Conference and Exhibition, 2017
Abstract In this paper, geomechanics is coupled with reservoir flow for modeling the depletion and deformation in fractured vuggy carbonate reservoir. Different from the dual- and triple-porosity models or the coupled approaches in which the vugs are considered as a continuous porosity, the vugs are treated as virtual volumes in this ...

Nitrogen gas channeling characteristics in fracture-vuggy carbonate reservoirs

Journal of Petroleum Science and Engineering, 2020
Abstract Tahe Oilfield, located in Tarim Basin, Northwest China, is a typical carbonate fracture-vuggy reservoir. Nitrogen gas flooding is a vital technology for improving oil recovery by enlarging sweep volume in fracture-vuggy reservoirs. However, gas channeling restricts further application of nitrogen gas flooding.

Equivalent porosity model & reservoir characterization for fracture/vuggy carbonate reservoir

Global Meeting Abstracts, 2009
The seismic reflection coefficients are influenced by various factors in fracture/vuggy Ordovician carbonate formation in the Tahe oilfield. An Equivalent Porosity Model was defined as the function or P-impedance from well logs, and geostatistical seismic inversion was carried out to get large numbers of high resolution P-impedance realizations. The co-
