multivariate optimization - Abstract:
- Any production well is drilled and completed for the extraction of oil or gas from its original location in the reservoir to the stock tank or the sales line. During their transportation from the reservoir to the surface, these fluids require energy to overcome friction losses and to lift products to the surface. The production system in use in an oil or gas field consists of several components where pressure losses may occur, thus affecting the well performance in terms of production rate. In order to optimize production performance and determine the exact effect of each component on the production rate, it is important to analyze the entire production system from the reservoir to the surface network. A model is presented here that will analyze the effect of selected parameters on the final performance of the production system of a natural gas field. A sensitivity analysis will be conducted for these parameters, thus displaying their individual and combined impact on the system performance in terms of production rate. This will be done by presenting several production scenarios and by analyzing the technical and economic influence of the selected parameters on the field, the objective being to determine the combination of parameters that will best allow the attainment of a given field production target.
