Does BOT have a method available for efficient removal of hard scale deposits in tubing and/or casing?
Mechanical removal of hard scale such as barium sulfate, strontium sulfate and iron sulfide on coiled tubing has always been a challenge. Baker Oil Tools’ Turbo Scale Mill can be used to remove scale from a tubing wall or to mill a pilot hole in scale-encrusted casing below the end of production tubing. The mill, run in combination with a Navi-Drill VIP or X-treme workover motor, or on threaded pipe, has a smaller contact area when milling, which reduces torque consumption. As a result, there are fewer motor stalls and the rate of penetration is increased. The Turbo Scale Mill’s aggressive milling matrix can mill different types of hard scale. However, stabilizer pads and brass dressed on top of the METAL MUNCHER™ inserts minimize the risk of damaging the tubing or casing wall. Another tool that removes cement, scale and other debris is the DB™ Underreamer. This rugged tool is designed to be used with a mud motor on coiled tubing to clean out the ID of casing below production tubing. I
