摘要

This work describes the use of semilog graphs of the free-gas gas/oil ratio (GOR) vs. cumulative oil production to analyze the performance of fields with large-scale gasflood operations. After gas breakthrough, and if field operations are reasonably constant, linear trends are found on these graphs and these trends can be extrapolated to project future oil recovery. This technique is similar to the use of semilog graphs of water/oil ratio (WOR) vs. cumulative oil production to analyze waterflood performance.The conceptual and theoretical bases for this approach are described, along with assumptions required to develop this technique from basic flow equations. Analysis of miscible-gasflood historical data from the Hassi Messaoud (HMD) (Algeria) and University Block 31 (west Texas, USA) oil fields is presented by use of this technique. As was the case with waterflood analysis using log-WOR-vs.-cumulative-oil-production graphs, for gasflood analysis this technique is shown to apply somewhat more generally than the theory might suggest. This technique is shown to be applicable at the individual-production-well level, pattern level, or for a reservoir as a whole.
