Improved Miscible Nitrogen Flood Performance Utilizing Advanced Reservoir Characterization and Horizontal Laterals in a Class I Reservoir - East Binger (Marchand) Unit Quarterly Report

A significant work program has been implemented in the East Binger Unit (''EBU'') miscible nitrogen injection project in an effort to reduce gas cycling and economically increase ultimate oil recovery. This work includes the drilling of new wells, both horizontal and vertical, as well as pattern realignment through producer-to-injector conversions. Monitoring of overall performance of the pilot area continues. Response to the various projects continues to be very favorable. Injection into the pilot area has nearly doubled, while gas production and nitrogen content of produced gas have both decreased. Nitrogen recycle within the pilot area has increased to 23% in recent months, but this is still far below the 58% recycle prior to initiation of the project. Two additional wells--EBU 65-2 and EBU 67-2--were brought on line during this reporting period. EBU 65-2 was successfully sidetracked after encountering thin pay on the edge of the reservoir, and is awaiting conversion to nitrogen injection service. The early performance of EBU 67-2 has been as predicted.
