A number of research activities have been carried out in the last three months. A list outlining these efforts is presented below followed by brief description of each activity in the subsequent sections of this report: (1) The available analytical solutions in the literature for steady state critical rates of horizontal wells are examined. Application of these methods to a cresting example show significant uncertainties in prediction of critical rates. (2) Sensitivity computations have been run for evaluating the effects of shale distribution on the performance of horizontal wells in heterogeneous reservoirs. (3) A number of single phase (water and oil) and two-phase (water and air) experiments have been completed in the Marathon Wellbore Model and the collected data are being analyzed. (4) A presentation of our project was given in the International Technology Forum DEA-44/67 on Horizontal, Slimhole, and Coiled Tubing, held by Maurer. (5) Our draft review report entitled ``Opportunities for Horizontal Wells and Problems in Predicting Their Performance`` has been completed.
