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 ...

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-

Modeling Multiphase Flow in Naturally Fractured Vuggy Petroleum Reservoirs

SPE Annual Technical Conference and Exhibition, 2006
Abstract A multicontinuum conceptual model is presented and implemented into a three-dimensional, three-phase reservoir simulator, using a generalized multicontinuum modeling approach. The conceptual model, proposed for investigating multiphase flow and displacement through naturally fractured vuggy carbonate reservoirs, is based on ...

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.

Research on Foam Flow and Flooding Characteristics of Fractured Vuggy Reservoirs

Volume 6: Offshore Geotechnics; Petroleum Technology
Abstract Foam flooding is an effective enhanced oil recovery method for deep fractured vuggy carbonate reservoir. This paper systematically investigates the flow behavior and displacement characteristics of foam in fractured vuggy carbonate reservoirs.

Oil Production and Water-Cut in Naturally-Fractured Vuggy Reservoirs

SPE Russian Oil and Gas Technical Conference and Exhibition, 2008
Abstract Naturally fractured oil reservoirs with vugs of size over 5 meters in diameter are few in the world. We developed a method to correlate the decrease in oil production and the increase in water cut. Production data from Tah oil reservoir (China) with big size vugs and high-density fractures were used to test the approach.

Pressure-Transient and Decline-Curve Behavior in Naturally Fractured Vuggy Carbonate Reservoirs

SPE Reservoir Evaluation & Engineering, 2002
Summary This study presents a new way to model high secondary porosity, mainly vuggy porosity, in naturally fractured reservoirs. New solutions are presented for two cases, one in which there is no primary flow through the vugs (which is an extension of the Warren and Root model) and one in which the dissolution process of pore throats ...
