The research examines well performance during transient through pseudosteady-state conditions to develop a fundamental understanding of these well systems. A new PC-based well productivity simulation software is introduced, which allows engineers to quickly simulate and visualize production performance of any well configurations in an anisotropic reservoir. It is designed to give a quick answer to well productivity forecasts and, thus, serve as an ideal screening tool. Multilateral and multibranch wells are destined to solve many current problems of petroleum reservoir management. Not only are the productivity or injectivity indexes generally superior to those of vertical wells, but reserves increases can be readily realized with these novel well systems. In particular, these wells can provide considerable improvements to the productivity index over single-horizontal wells. In the presence of areal permeability anisotropy, they can also reduce the risk between maximum and minimum potential production. The length and number of branches can be optimized by balancing incremental production against the costs of drilling and well completion. Multilaterals in low- to moderate-permeability reservoirs can maintain high production and cumulative production rates. In higher-permeability reservoirs the incremental benefits from multilaterals are reduced. However, at early time and under transient conditions in low- to medium-permeability reservoirs, the relative productivity improvements provided by multilaterals may result in sufficient incremental benefits to warrant their drilling. The open length of the horizontal well can be reduced--in many cases, without a substantial decrease in the productivity index--over a fully open well. The length of open intervals can be optimized by balancing incremental production benefits against the costs of well completion. Dimensionless IPR curves were calculated for horizontal and multilateral wells in solution-gas-drive reservoirs. These reservoirs encompassed a wide range of reservoir data, PVT properties, and relative permeability characteristics. Bubblepoint pressure and reservoir depletion had a significant effect on the curves. The new reference curves allow a simple means with broader applications to predict the performance of these wells.
