SWITCHBACK SCRAPER tool and MAGNOSTAR magnet combination streamlines operations
M-I SWACO recommended using its SWITCHBACK SCRAPER versatile casing cleaning tool in combination with three MAGNOSTAR high-capacity magnets to optimize operational efficiency.
The SWITCHBACK SCRAPER tool runs in the hole with its blades in the recessed position. When drilling operations are complete, a ball is dropped to contact the scraper tool. When the ball impacts the tool's seat, pressure is applied to the recommended level to activate the tool, and the pads extend outward and contact the casing wall. The activated tool then rotates through the area being prepared while fluid is circulated to remove dislodged debris.
Three MAGNOSTAR magnets were run in the string to capture and recover the debris generated by the SWITCHBACK SCRAPER tool. Ideal for large-volume cleanup, each MAGNOSTAR magnet can retrieve up to 200 lbm [91 kg] of ferrous debris.
