OPTIMAL STRATEGY FOR CYCLIC STEAM STIMULATION OIL PRODUCTION: A MATHEMATICAL MODEL
HUAXIONG HUANG AND MARC PAULHUS
Abstract. A central issue of managing a heavy oil production
using cyclic steam stimulation process is whether an
optimal strategy for adding new wells and removing old wells
can be found. In this paper we present a mathematical model
which provides a general framework for this type of problem.
With suitable assumptions, we formulate the production process
as a constrained optimal control problem in continuous
time or equivalently a constrained linear programming problem
in discrete time. The main advantage of the model is that
the size of the problem is not necessarily related to the scale
of the operations (number of wells). A numerical algorithm
based on the model shown to be efficient is given, as well as
results for two test cases of large scale projects.
