RESERVOIR AND WELL COUPLING SIMULATION WITH DISTRIBUTED ALGORITHM

Domain Decomposition Algorithm and Analytical Simulation of Coupled Flow in Reservoir / Well System

A model and analytical method for solving a problem of coupled fluid flow in the reservoir/well system is presented. The 3-D drainage area is composed of three connected media: the tubing, the annuli (considered as a super conducting collector), and the reservoir itself. To couple the fluid flows in these areas a non-overlapping Dirichlet-Neumann domain decomposition method is developed theoret...

A Review of Coupled Dynamic Well-Reservoir Simulation

The numerical simulation of the dynamic interaction between hydrocarbon reservoirs and wells has been an object of study for over three decades. Such a coupled approach is necessary to solve a variety of dynamic flow problems, such as pressure transient analysis (well testing) with wellbore storage, liquid loading, near-well reservoir clean-up, unstable gas lift, or the development of smart wel...

A distributed algorithm for average aggregative games with coupling constraints

We consider the framework of average aggregative games, where the cost function of each agent depends on his own strategy and on the average population strategy. We focus on the case in which the agents are coupled not only via their cost functions, but also via affine constraints on the average of the agents’ strategies. We propose a distributed algorithm that achieves an almost Nash equilibri...

A Convergent Algorithm for Time Parallelization Applied to Reservoir Simulation

Parallel methods are not usually applied to the time domain because the sequential nature of time is considered to be a handicap for the development of competitive algorithms. However, this sequential nature can also play to our advantage by ensuring convergence within a given number of iterations. The novel parallel algorithm presented in this paper acts as a predictor corrector improving both...
