Latest Patents
One of Dale's latest patents is titled "Through Tubing P AND A with Bismuth Alloys." This method describes a technique for plugging a hydrocarbon well using a through-tubing approach. The process allows the tubing to remain in place while only a short section, less than 2 meters, is cut, milled, perforated, ruptured, or expanded. A blocking device is sent downhole to block the bottom of the plug section, and bismuth alloy pellets are dropped onto this device. A heater is then deployed to melt the bismuth alloy pellets, which cool and solidify, expanding to fill the section of the well that needs to be plugged. Once primary and secondary barriers are established, the well can be closed, and the Christmas tree removed. This innovative method can also facilitate the setting of a rock-to-rock plug by removing or partially removing the tubular and outer casing.
Career Highlights
Dale R. Doherty has built a successful career at ConocoPhillips, where he has applied his expertise in well plugging techniques. His work has been instrumental in advancing the methods used in the oil and gas industry, ensuring safer and more effective operations.
