In the fifth quarter of this project, progress was made concerning four of the stated objectives of the project. First, extensive sensitivity studies, based on reservoir simulation, have been performed on a field example to assess the effects of wellbore friction, inflow, skin, length, and diameter of the well, etc. on the productivity of a horizontal well. Secondly, the authors have launched a new phase of the project on developing models for scale-up and coarse grid pseudo functions for horizontal wells in heterogeneous reservoirs. The available methods have been applied to an example problem and their performance and limitations have been analyzed. Thirdly, the authors are in the process of developing a new analytical solution for the coning and cresting critical rates for horizontal wells. Finally, experimental data bases will be used to test the authors` newly developed general mechanistic model for two-phase flow.
