The recovery of oil from subsurface reservoirs often requires the injection of water or gas to
maintain reservoir pressure and to displace the oil from injection to production wells. The …

Closed-loop reservoir management is a combination of model-based optimization and data
assimilation (computer-assisted history matching), also referred to as 'real-time reservoir …

Dynamic optimization of waterflooding using optimal control theory has significant potential
to increase ultimate recovery, as has been shown in various studies. However, optimal …

In this paper, we develop an efficient algorithm for production optimization under linear and
nonlinear constraints and an uncertain reservoir description. The linear and nonlinear …

A novel correlation identifying inefficient drilling conditions is presented using experimental
and field data. Historically, Mechanical Specific Energy (MSE) has been used to improve the …

This paper proposes an augmented Lagrangian method for production optimization in which
the cost function to be maximized is defined as an augmented Lagrangian function …

Performing a line search method in the direction given by the simplex gradient is a well-
known method in the mathematical optimization community. For reservoir engineering …

In the process of reservoir development, we always wish to drill wells at optimal locations so
that more hydrocarbons can be extracted at a lower cost. Because well locations in a …

Well architecture advances from conventional wells to horizontal. Then multilateral wells,
which have maximized reservoir contact, have been paralleled by advances in completion …

An adjoint formulation for the gradient-based optimization of oil–gas compositional reservoir
simulation problems is presented. The method is implemented within an automatic …
