A method of cleaning perforations and slotted liners with fluids pumped at high pressure is enhancing oil production. During the last 5 months of 1981, in the Cymric Field near Bakersfield, California, 12 wells with significant production declines were scheduled for cleaning of the down-hole slotted liners which serve as production strings. As a result of the cleaning (utilizing a process and tool assembly whereby directionally controlled hydraulic energy is applied through very small jet nozzles) the wells, as a group, responded with a significant production increase. Although in a few instances production decreases were recorded, the majority of the wells responded so well that an overall 90% increase was achieved and was sustained for a considerable period after the hydraulic perforation cleaning service.
