PDF Version Also Available for Download.

Description

The following activities have been carried out in the last three months: Work on developing a three-dimensional Voronoi grid simulator is progressing. Extensive testing of the grid generation and visualization modules of the simulator is continuing while modifications and improvements are being made to these capabilities; The recently developed semi-analytical method for calculating critical cresting rates is being extended for the case of simultaneous gas and water coning toward a horizontal well; The accuracy of available correlations and analytical models for breakthrough times of horizontal wells is being investigated through simulations of a field case; Work on developing methods for ... continued below

Description

The following activities have been carried out in the last three months: Work on developing a three-dimensional Voronoi grid simulator is progressing. Extensive testing of the grid generation and visualization modules of the simulator is continuing while modifications and improvements are being made to these capabilities; The recently developed semi-analytical method for calculating critical cresting rates is being extended for the case of simultaneous gas and water coning toward a horizontal well; The accuracy of available correlations and analytical models for breakthrough times of horizontal wells is being investigated through simulations of a field case; Work on developing methods for coupling between reservoir and the werbore through a network modeling approach is progressing. The current stage of the study involves evaluation of available analytical methods; The necessary modifications have been made to the rig at the Marathon facility and the high rate two-phase flow experiments are about to commence; new correlations for wall friction and interfacial friction factors have been developed for the stratified flow in horizontal and inclined pipes. After further testing this new approach will be used in our mechanistic model; and this quarterly report has been entirely devoted to the task fisted in the last item above and we only present an abridged version of the Masters report of Mr. Liang-Biao Ouyang on which it is based. The complete study will be included in the next Annual Report of the Project.
