Book Productivity and Injectivity of Horizontal Wells Quarterly Report April 1 1994 June 30 1994

Download or read book Productivity and Injectivity of Horizontal Wells Quarterly Report April 1 1994 June 30 1994 written by and published by . This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1994 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three months we have studied coning and cresting behavior in horizontal and vertical wells using the commercial simulator, Eclipse. In our second quarterly report we compared the predications of five analytical methods for critical rates and presented the results in a table for a gas-cresting example problem. In this quarterly report, wee present simulation results for the coning and cresting critical rates for vertical and horizontal wells.

Available in PDF, EPUB and Kindle. Book excerpt: This quarterly report reports on the efforts on Task 2, effects of reservoir heterogeneities on performance prediction of horizontal wells. Performance prediction of horizontal and non-conventional wells based on both analytical and numerical tools rarely match actual performance. Even a history matched case with sufficient production data fails to give reliable predictions for long times. In this study the authors explore reasons for the inability of predictive tools to make accurate predictions. They consider a case where a vertical well has been drilled and cored. Then, they generate twenty consistent geostatistical descriptions of permeability and porosity that are all constrained to hard data obtained from the vertical well. Simulations with these realizations show large differences in production rate, WOR and GOR predictions as a result of variations in reservoir properties. It is also shown that the effect of well index (WI) on simulation results is large. Furthermore, for the example considered, analytical models for critical rate and productivity calculations were found to have limited practical use.

Book Productivity and Injectivity of Horizontal Wells Annual Report March 10 1993 March 9 1994

Available in PDF, EPUB and Kindle. Book excerpt: In this report, the investigators review a range of reservoir scenarios in which horizontal wells can be advantageous and discuss some of the modeling problems associated with calculating well connection factors, productivity indices, coning behavior and well two-phase pressure drops. We show illustrative coning calculations and the implications of the well model on distribution of post-breakthrough gas saturations. Such calculations then open up the possibility of determining optimal recompletion strategies and/or additional hydraulic fracturing.
