Abstract
A method for allocating optimum fluid volume among a set of injectors of a hydrocarbon reservoir includes, for each of multiple depletion stages of the reservoir, determining reservoir pressure at a first region, corresponding to a first injector, in relation to average field reservoir pressure, determining reservoir pressure at a second region, corresponding to a second injector, in relation to average field reservoir pressure, and injecting fluid through the first and second injectors independently and as a function of the determined reservoir pressures at the first and second regions respectively.

A method for allocating optimum fluid volume among a set of injectors of a hydrocarbon reservoir, the method comprising:
- for each of multiple depletion stages of the reservoir:
- determining reservoir pressure at a first region, corresponding to a first injector, in relation to average field reservoir pressure,
- determining reservoir pressure at a second region, corresponding to a second injector, in relation to average field reservoir pressure, and
- injecting fluid through the first and second injectors independently and as a function of the determined reservoir pressures at the first and second regions respectively.
A hydrocarbon reservoir pressure management system comprising:
- a plurality of injectors each associated with at least one region of a field of a hydrocarbon reservoir;
- a pressure injection controller configured to receive as inputs physical data and measurement data in connection with the reservoir;
- and
- a balancer operable to, at successive reservoir depletion stages:
- determine from the physical data and measurement data reservoir pressures at first and second regions in relation to average field reservoir pressure, and
- independently drive injection volumes of first and second injectors, respectively corresponding to first and second regions, based on the determined reservoir pressures.
A machine-readable storage medium having stored thereon a computer program for allocating optimum fluid volume among a set of injectors of a hydrocarbon reservoir, the computer program comprising a routine of set instructions for causing the machine to perform the steps of:
- for each of multiple depletion stages of the reservoir:
- determining reservoir pressure at a first region, corresponding to a first injector, in relation to average field reservoir pressure,
- determining reservoir pressure at a second region, corresponding to a second injector, in relation to average field reservoir pressure, and
- injecting fluid through the first and second injectors independently and as a function of the determined reservoir pressures at the first and second regions respectively.
