Applications of response surface methodology and Box-Behnken design to optimise fracture treatment design for Lower Miocene reservoirs, Bach Ho field
The paper presents the results of application of the response surface method and the Box-Behnken design of experiments to investigate the influence of hydraulic fracturing parameters on the economic performance after fracture treatment in the Lower Miocene reservoirs of Bach Ho field. The four parameters comprising viscosity of fracturing fluid, pump rate, proppant concentration, and fracture length are optimised by maximising net present value (NPV). The NPV is calculated based on the cumulative oil production at the post fractured and the based case under transient flow behaviour for a three-year period. From the results of the sensitivity analysis, it is possible to evaluate the main parameters that affect the net present value (NPV), as well as the interaction of the parameters to the NPV.
