Conventional Wells Productivity Enhancement

In an effort to reduce costs and improve efficiencies, the operator of a prolific conventional oil field decided to change drilling and completion fluids composition and weight, resulting, among other things, in overbalance perforating conditions. The operator noticed the average IP of the new wells was below the average IP of the wells previously drilled and completed in areas where depletion was not expected and similar reservoir properties.

• The average production increase of the wells treated was 25%
• Underbalance perforating became the new standard for new and existing wells
• A field-wide productivity enhancement campaign was initiated following the established workflow
