The Simultaneous Effect of Wellbore Friction and Multi-lateral Well Arrangement on the Prediction of the Performance of Non-Conventional Wells
Abstract/Contents
- Abstract
- Multi-lateral wells are now becoming common and the length of each lateral can be thousands of feet long. Many tools have been and continue to be developed for the prediction of their performance. Still, it is very difficult to get good predictions. The aim of this study was to see why it i s so difficult to predict the performance of these wells by evaluating the factors that could have a significant effect on the results. We considered: (1) Reservoir Heterogeneity, (2) Multi-lateral Well Arrangements, and (3) Wellbore Friction as the factors that could have significant effects on the predictions of performance.We generated 6 types of multi-lateral wells and simulated them both with and without wellbore friction. These simulations were conducted both i.n a homogeneous model and 20 heterogeneous realizations that were generated geostatistically using GSLIB. Then we compared the results from each case and evaluated the effects. The comparisons showed that reservoir heterogeneity causes lower water and gas oil ratios and shorter plateau lengths for oil production rate than is observed in a homogeneous reservoir. Multi-lateral well arrangements, where large interference occurred, led to higher water and gas oil ratios and shorter plateau lengths. Higher wellbore friction pressure loss also led to higher water and gas oil ratios and shorter plateau lengths.In this report, we also discuss the effect of the combination of these factors and offer the most likely explanations for these results.
