Demonstrates that CHOPS can be attained in Horizontal wells, and that sequential CHOPS in a Horizontal well can increase recovery on a recompletion by up to 16 times at a capital cost of between $4 and $6 per recovered barrel, and as a development tool with mile long laterals can increase recovery by 30% at a capital cost of between $7 and $13.50 per recovered barrel. A case history of a well where the slotted liner was perforated twice shows that perforating resulted in incremental recovery even though it was not CHOPS production.#PCpump #perforating #heavyoilrecoverymethods #jetpump #DrillingandCompletions #sandproduction #CHOPS #ProductionandOperations
