Numerical Simulation of Three-Phase Flow in Deforming Fractured Reservoirs
Numerical Simulation of Three-Phase Flow in Deforming Fractured Reservoirs — The mathematical formulation of a three-phase, three-dimensional fluid flow and rock deformation in fractured reservoirs is presented in this paper. The present formulation accounts for the significant influence of coupling between the fluid flow and solid deformation, an aspect usually ignored in the reservoir simulat...
متن کاملCoupling Geomechanics and Transport in Naturally Fractured Reservoirs
Large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. Canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in Alberta, most of this being bitumen of viscosity greater than 106 cP in the GrosmontFormat...
متن کاملEnhanced Gas Drainage from Undersaturated Coalbed Methane Reservoirs
Traditional methods of coal seam gas drainage rely on the use of reservoir pressure reduction to promote gas desorption from the coal matrix. Studies in coal mining gas drainage operations, particularly in coal seams that are deeply undersaturated and have low permeability, found the rate of reservoir pressure reduction was prohibitively slow. In such conditions, lengthy production delays have ...
متن کاملSimulation of Coupled Single-phase Flow and Geomechanics in Fractured Porous Media
Accurate predictions of the complex interactions between fluid-flow and mechanical deformation in fractured geologic formations is of interest in a wide range of reservoir engineering applications including subsurface CO2 sequestration, heavy-oil recovery, and wellbore stability. In this report, we describe a fully implicit method for coupled geomechanics and fluid flow in naturally fractured p...
متن کاملNumerical Simulation of Coalbed Methane Seepage in Pinnate Horizontal Well Based on Multi-Flow Coupling Model
Abstract: The motive of the study is to establish a seepage flow model of pinnate horizontal well in infinite reservoir according to the characteristics of 3D distribution of CBM pinnate horizontal well. Taking flow pressure drop along the main and branch boreholes into consideration, the fluid flow formulas of CBM pinnate horizontal well are proposed. The corresponding calculation program has ...
