Reliable shoe-to-shoe delivery of a longer curve-lateral section with NitroForce® motorDownload PDF
Build, land, and drill lateral section in a single run, in high temperatures
Utilize NitroForce 500 motor
The enhanced NitroForce® high torque, high-flow motor proved its exceptional drilling performance in the harsh, high-temperature conditions of the Eagle Ford shale formation. It enabled smooth building of the curve despite dogleg severity (DLS) of 10 degrees per 100 ft and drilling of the entire lateral to total depth (TD) in just one run, trouble-free.
ft in a single curve-lateral run
The 5-in. NitroForce motor with a titanium flex shaft eliminated the need for seals or rubber boots, making it able to withstand rising temperatures. It was modified to run with a high torque 6/7 10.0 extended length power section and operate at a speed of 0.84 rev/gal, able to handle flow rates up to 350 gpm. This enhanced design of the motor provided an excellent rate of penetration (ROP), enabling the well to be finished on time.
The newly designed NitroForce motor continuously drilled the entire section in 114 drilling hours and 169 circulating hours. The motor started the run with 42 degrees of inclination, and then navigated consistent doglegs to finish the curve and continue into the lateral. In the lateral, the motor equilibrium averaged less than .5°/100 ft of change while rotating, minimizing the need to slide and increasing the overall ROP. After drilling 7,467 ft, the assembly reached a TD of 20,215 ft and an ultimate bottomhole temperature of 340°F. The customer was extremely pleased with the motor’s ability to smoothly and efficiently run the completion string with the desired reliability.
