Record Extended Lateral Interval in Southern Lea County, New Mexico

HCC’s 8.75″ DP606X completed COG’s aggressive extended reach lateral in one bit and with record time. Subject bit drilled 9448ft with an interval ROP average of 75.1ft/hr. Total time of the interval is 125.75hrs. The bit was run on a bent PDM assembly.


The closest competitor offset to this subject run and well profile is on a nearby well. This offset utilized
two Ulterra 7.875” U516Ms to achieve the same interval. Utilizing the two Ulterra bits, the offset’s overall interval time was doubled to 202.2hrs. Also, a slower ROP interval average was recorded at 51.9ft/hr.
