Embodiment Construction

[0063] Systems and methods are provided for use in predicting sand production of geomechanical reservoir systems. The systems and methods use measured reservoir properties to generate such sand production predictions, which are useful in that they allow early in a reservoir development project to determine if and when sand production will occur and at what rate. of.

[0064] Such sand production predictions can be used early in a reservoir development project to determine the type of completion technique that can be implemented to completely eliminate sand production or to allow some amount of gradual sand production (sand production Gradual time evolution), but this completion technology will not lead to large-scale sand production. For example, the design of a barrier system used around a wellbore in a reservoir may be determined, such as, but not limited to, sand screen technology or gravel packs. It can be determined whether unconsolidated formations with multiple pay zo...

Abstract

Systems and methods are provided for use in predicting sand production in a geomechanical reservoir system. Computation of the sand production predictions can include solving a system of partial differential equations that model the geomechanical reservoir system. Systems and methods also are provided for use in operating a geomechanical reservoir system based on the sand production prediction for controlling sand production in the geomechanical reservoir system.

Description

technical field [0001] This paper relates to computer-implemented systems and methods for use in predicting sand production in geomechanical reservoir systems. This document also relates to systems and methods for use in controlling sand production in a geomechanical reservoir system based on the predictions. Background technique [0002] Production of a reservoir system typically follows the development of the reservoir in which reservoir fluids, such as hydrocarbons (oil or gas), are withdrawn from the reservoir. Sand production is an event in which formation solid particles are produced along with reservoir fluids. The general term used to describe the small formation (rock surrounding the wellbore) particles that may be produced with reservoir fluids is "sand". The term "microparticle" has been used in some literature. Reservoir formation materials generally include rock types with sufficient porosity and permeability to store and transport reservoir fluids, such as o...
