Evaluation of reservoir discontinuity has been used by industry to estimate potential oil recovery to be realized from infill drilling. That this method may underestimate the additional recovery potential is shown by continuity evaluation in a West Texas carbonate reservoir, as infill drilling progressed from 40-acre (16.2-ha) wells to 20-acre (8.1ha) wells and eventually to 10-acre (4.1-ha) wells. Actual production history from infill drilling in nine fields, including carbonate and sandstone reservoirs, shows that additional oil recovery was realized by improving reservoir continuity with increased well density.
