摘要

The combined use of propellants and perforating forrnproduction enhancement is not new to the petroleum industry,rnespecially for natural completions in competent formations.rnWhen used together, the propellant is shaped in the form of arncylindrical sleeve that is positioned over a scallopedrnperforating carrier to combine the perforating and stimulationrnprocesses into one step. The perforating event is performed inrneither an under-balanced or balanced condition, followedrnimmediately with the extreme over-balance or rapid-gas pulserngenerated from the propellant burn. This technique providesrnan effective method to ensure that all perforations arernsufficiently broken down from the fracturing to accept eitherrnproduced or injected fluids.rnThis paper will review a new application for the combinedrnpropellant / perforating technique that has been successfullyrnused in unconsolidated formations in the Gulf of Mexico.rnThe propellant / perforating technique was used to enhancernthe placement of proppant during frac-and-pack and gravelrnpack treatments while perforating in a balanced condition.rnThe propellant / perforating technique was used on severalrnformation types; I.e., long intervals, highly deviated, andrnhighly laminated with extreme permeability contrasts, thatrnwould traditionally be deemed as high risk for proper sandrnplacement.rnIn performing this technique, the propellant sleeves arernpositioned across the lower quality portions of the intervalsrnwith low permeability and resistivity to ensure that thernperforations in these intervals would be broken down to acceptrnfracturing fluids and proppant during the fracturing treatmentrnconsistent with the entire treated interval.rnCase histories from Gulf-of-Mexico operators have shownrnthat this technique is effective in both underbalanced andrnoverbalanced perforating situations. With the trend in thernindustry to reduce cycle time, the elimination of thernunderbalance/surge process to ensure clean perforations andrnall the associated rig time in obtaining control of the wellrnfollowing the surge are seen as significant opportunities forrnrig-time savings.rnIt has also been proven that combining propellant/rnperforating in a balanced scenario can offer a cost efficient andrnsafe method when used as a near wellbore clean-up tool forrnpre-frac preparation or high rate water packing.
