Productivity and injectivity of horizontal wells. Quarterly report, October 1--December 31, 1996

PDF Version Also Available for Download.

Description

This report describes progress on Tasks 1 and 4, Correlations for cresting behavior in horizontal wells. Research work on developing coarse grid methods to study cresting in horizontal wells was continued. The previous correlations for optimum grid size, breakthrough time, and post breakthrough behavior (i.e., water-oil ratio) were further tested and optimized. Procedures to derive pseudo-functions either using numerical correlations or coarse grid simulations have been proposed and successfully tested. The results reported here and other calculations show that the correlations developed in this work can be applied to a wide range of conditions for predicting the water break-through time ... continued below

Description

This report describes progress on Tasks 1 and 4, Correlations for cresting behavior in horizontal wells. Research work on developing coarse grid methods to study cresting in horizontal wells was continued. The previous correlations for optimum grid size, breakthrough time, and post breakthrough behavior (i.e., water-oil ratio) were further tested and optimized. Procedures to derive pseudo-functions either using numerical correlations or coarse grid simulations have been proposed and successfully tested. The results reported here and other calculations show that the correlations developed in this work can be applied to a wide range of conditions for predicting the water break-through time (BT) and the water-oil-ratio (PBB) for horizontal wells. All of the correlations are based on the assumption of two-phase, two-dimensional flow in homogeneous reservoirs.
