This project investigated the potential optimal development strategy for a
saturated reservoir, with a gas cap. It assessed the viability of three production
methods—solution gas drive (primary depletion), water
flooding and gas injection, using varying injector well numbers. This project also
undertook sensitivity analysis in the field, concluding that the development of another appraisal well would vastly improve the accuracy of
NPV calculation. Furthermore, this project ascertained an optimized recovery method,
based on numerical production simulations and economic modelling, of initial solution
gas drive recovery, until reservoir pressure
equals the bubble point pressure, at which point three water flooding injectors should be employed, developed at six-month intervals to maximise production while limiting CAPEX and OPEX as much as possible.
