| Abstract:
|
Conventional recovery techniques enable recovery of 10-50% of the oil in an oil eld.
Advances in smart well technology and enhanced oil recovery techniques enable signicant larger
recovery. To realize this potential, feedback model-based optimal control technologies are needed
to manipulate the injections and oil production such that
ow is uniform in a given geological
structure. Even in the case of conventional water
ooding, feedback based optimal control
technologies may enable higher oil recovery than with conventional operational strategies. The
optimal control problems that must be solved are large-scale problems and require specialized
numerical algorithms. In this paper, we combine a single shooting optimization algorithm
based on sequential quadratic programming (SQP) with explicit singly diagonally implicit
Runge-Kutta (ESDIRK) integration methods and a continuous adjoint method for sensitivity
computation. We demonstrate the procedure on a water
ooding example with conventional
injectors and producers. |
