Systems / On Shore / Surface Casing Vent Flow

The Gator perforator can perforate and test injection of individual zones in a single run. In certain applications the client has the ability to cement and squeeze cement into multiple zones in a single trip. In wells with surface casing vent flow the perforations created by the Gator perforator can significantly increase your chance of locating the source of the vent flow.
