A Delaware Basin operator in Reeves County, Texas, struggled with needing to make multiple trips per lateral section, partly because of frequent damaged-beyond-repair bits. They wanted to run more aggressive bits to increase the rate of penetration, but these bits incurred damages due to axial vibrations and lack of bit engagement, which were driving up their costs.
Solution: Cougar Downhole Tools
Cougar Drilling Solutions analyzed the bottom hole assembly, well profile and drilling performance requirements and discussed specific objectives with the operator’s drilling team.
The Mechanical Thruster reduces the severity of shock and vibration, limiting the detrimental effects to the bottom hole assembly and bit. Cougar optimized the Mechanical Thruster’s configuration and placement based on the operator’s well specifications. This ensures that the operator gets maximum results and effectiveness from the tool.
The drilling engineer chose a bit that typically damages quickly but provides a higher rate of penetration. With Cougar Drilling Solutions’ downhole thruster, the operator achieved back-to-back record runs on two rigs, with less than 10,000 feet drilled with a single bottom hole assembly on each well. The average section drilled needed 2.5 fewer bits than without the Mechanical Thruster.
By making fewer trips and spending fewer days drilling, the operator saved an average of $142,500 per well.
