As development of hydrocarbon reserves continues to move into deeper and more complex reservoir conditions, operators have found that conventional techniques for testing, perforating, and stimulating may not provide satisfactory results in severe well conditions. A method was developed to optimize well-testing operations, improve safety, and reduce costs without compromising the results by replacing traditional drillstem testing (DST) operations. The technique can eliminate the need to kill the well to retrieve the guns and provides flexibility to test, evaluate, and fracture treat the well.
