To reduce trips, time, and costs, Ecopetrol’s original plan was to trip with tubing-conveyed perforation (TCP) to perforate a 7-in liner, and then use a second trip to run a RIDGEBACK BURR MILL perforation deburring tool to condition and clean the perforated section in preparation for subsequent run of an isolation packer between formations K1 and K2. Schlumberger proposed perforating and cleaning in the same trip using a higher-torque tubing to convey the perforation tool and deburring tool. The BHA would also include a MAGNOSTAR high-capacity magnet to capture metal debris to avoid equipment or formation damage.
