摘要

A considerable number of studies have been conducted tooptimize the perforated completions for horizontal wells, butvery few of them took into account the effect of reservoirheterogeneity and coning problems in the completion design. One of the most relevant work directly related to this topic isthe one developed by Goode and Wilkinson 7. They havepresented an analytical solution for the performance ofpartially completed horizontal well. Their model, however, hastwo major limitations:(1)it considers the reservoir ashomogeneous and ignores heterogeneity, and (2)it does nottake into account the water and gas coning effects. In this study, a numerical solution has been developed tooptimize the perforated completions for horizontal wells in aheterogeneous reservoir laying between a large gas cap and anactive aquifer (double coning problem). Another objective ofthis study was to examine the performance of various perforation schemes for horizontal wells in Hassi R'mel oil Rimusing reservoir simulation. Since the capability of the numericalsimulators to model a horizontal well performance is largelycontrolled by the quality of the geological description of thereservoir, therefore, a reservoir characterization based ongeological (sedimentary)units was performed on the A-Sandreservoir of Hassi R'mel oil Rim. The simulation modeling in this study was undertaken in twolarge parts. First, a sensitivity analysis was conducted toinvestigate the effects of the most relevant reservoir parameterson the horizontal well performance for different perforationschemes. This allowed us to examine the effect of theperforation length and its distribution and to find the optimumperforation scheme for horizontal wells in Hassi R'mel oil Rim. Second, the simulation modeling was involved in a real casewhere the performance of the well HRZ-09 was a concern. Thereason for taking this well as a case study is that it wascompleted non-conventionally using the Inverted High Angle
