Abstract
A review of the status and experiences gained in the M-6 steam drive project after 3 yr of steam injection is presented. The M-6 project is being conducted in a fully depleted heavy oil reservoir of Venezuela Bolivar Coast field, and comprises 151 wells of which 19 are injectors. The review is based on the overall project performance and describes operational problems, steam plant performance, production forecast and special data acquisition. After a total of ca 7.8 x 106 metric tons of steam injected, steam breakthrough has been observed in some hexagons. Remedial shut off in oil production wells have performed successfully. The M-6 project continues to provide useful experience and information which will be used in planning future steam drive projects in the heavy oil reservoirs of the Bolivar Coast.
