Productivity and injectivity of horizontal wells. Quarterly report, October 1, 1994--December 31, 1994
The following activities have been carried out in the last three months. Work on developing models for scale-up and coarse grid pseudo functions for horizontal wells in heterogeneous reservoirs was continued. Work has been started on developing a generalized model for calculating productivity and infectivity indices for a horizontal well in anisotropic reservoirs. The goal is to be able to calculate productivity of complex well configurations which are becoming common such as multiple horizontal wells of arbitrary direction emanating from one vertical well. Work has also been commenced on studying completion designs and their impact on production performance of a horizontal well. Work on developing a three-dimensional Voronoi grid simulator is progressing. A major facet of this work is to be able to generate and visualize gridding geometry in 3D. This aspect of the work has been completed and is currently being tested. This quarterly report has been entirely devoted to the task listed in the last item above. After a brief overview of Voronoi grids and the scheme employed in generating them, samples of gridding geometry in 2D and 3D produced by the Voronol grid simulator are presented.
