Additional gains in depth control are available by integrating a casing collar locator and gamma ray detector. To ensure target zone coverage, ACTive Perf CT real-time perforating service is available for single-run perforating with accurate depth control, hydrostatic balance control, and avoidance of formation damage, formation fluid invasion, and formation sanding. The service can be deployed with other ACTive services tools to provide operators with additional information. Perform live well perforating CT perforating is ideal for live wells. Pressure control techniques are used to run long gun strings and either drop off or retrieve the guns without having to kill the well. Improve subsea well perforating In subsea wells, the subsea lubricator defines the length of gun that can be run. With other wells, the surface riser or surface lubricator valve determines the length of gun. CIRP completion insertion and removal under pressure equipment can be used in conjunction with CT to deploy and retrieve guns under pressure. Pressure control techniques with CT can simplify perforating operations by enabling the use of a long BHA while maintaining dual well control barriers. ACTive Perf service enables single-run perforating with accurate depth control, hydrostatic balance control, and avoidance of formation damage, formation fluid invasion, and formation sanding. Achieve depleted well perforating In depleted wells where drawdown is insufficient, nitrogen can be circulated at convenience to lighten the overall fluid column, increasing the drawdown at the zone of interest. The resulting pressure differential is similar to that produced by gas lift systems. Widen options for gun activation There are several ways to activate guns run with CT, including hydraulic delay firing heads drop ball firing heads eFire-CT coiled tubing–deployed firing head the use of circulation rates electrically, with stiff-wire CT, which uses standard wireline correlation tools. Hydraulic CT enables stimulation fluids to be pumped without the risk of damaging a wireline cable. The pump-over specialty gun is used during fracture operations in horizontal wells to save a cleanout trip between fracturing and perforating the next interval. It allows circulation through a special sleeve on the outside of the gun to the bottom of the string.
