H&P Saves Operator 11 Days and Lowers BHA Count by 9%
Challenge
An operator in the Delaware basin was proactively looking for ways to maximize efficiencies in its well program by decreasing the number of days spent on the well and by lowering bottomhole assembly (BHA) count. One well had been drilled on the pad, and the initial spud to total depth (TD) was 32.4 days and 22,330 feet.
Solution
After collaborating with the customer to understand the desired outcome, H&P recommended an integrated solution to address multiple outcome deliverables. By using FlexDrill® software in conjunction with H&P’s Autodriller control system, the customer can enable set point automation to increase the efficiency of the rig and reduce the overall mechanism specific energy (MSE) and downhole dysfunctions like whirl and stick slip. The system automatically stages drilling set points after tagging bottom, further reducing risk and accelerating the well program. By design, this system is set up to deliver maximum efficiencies while reducing the learning curve to achieve repeatable results. The FlexDrill system also preserves BHA, reducing the flat time attributed to tripping in and out of the hole to change out bits and tools.
Outcome
The configurable and consistent bit engagement enabled through H&P’s FlexDrill software helped ensure optimal contact with the formation, resulting in a 61% average rate of penetration (ROP) improvement. Additionally, by reducing bit and BHA torsional and lateral vibration through the H&P Autodriller control system, fewer BHAs were required to drill the well.
Overall, H&P helped the operator reduce BHA change count by 9%, which meant one fewer BHA used in an area of especially hard drilling. They saw an 11-day improvement over the previous well, which equates to a 26% time savings.
