An overview of SPE paper 71639:Field performance of propellant/perforating technologiesto enhance placement of proppanton high-risk sand-control completionsKent Folse, Halliburton Energy Services
Developing new applications for the StimGun™
assembly has been a priority. Typically, a newapplication will increase well productivity orreduce costs. Halliburton, with customer assis-tance, has successfully developed a new applica-tion for improving frac-and-pack treatments thatimproves production, reduces costs, and increasessafety. “SPE paper 71639: Field Performanceof Propellant/Perforating Technologies toEnhance Placement of Proppant on HighRisk Sand-Control Completions” by Kent C.Folse, Richard L. Dupont, and Catherine G.Coats, SPE, Halliburton Energy Services, Inc.,David B. Nasse, Shell Offshore, Inc. present-ed at the 2001 SPE Annual TechnicalConference in New Orleans, Louisiana, is anexcellent example of the benefits for cus-tomers of assisting in the development ofnew applications.
Traditionally, proper frac-and-pack prop-pant/sand placement was difficult in uncon-solidated formations with long, highly devi-ated, highly laminated intervals withextreme permeability variations. To ensurethat the low permeability intervals acceptfracturing fluids and proppant during treat-ment, a Gulf of Mexico operator used theStimGun™ assembly to break down the per-forations prior to the fracturing treatment.The tubing-conveyed perforating jobs werecompleted in a balanced condition withonly the lower quality intervals being stimu-lated with the StimGun™ assembly. Two verydetailed case studies are presented in thetechnical paper. It was concluded that com-bining propellant/perforating in a balanced
scenario could improve proppant placement, costefficiency, and safety.
The entire SPE paper 71639 is included in theAppendix with due recognition to the Society ofPetroleum Engineers for allowing its republication.
