In the current fast-paced drilling operations environment, the ability to measure and evaluate downhole dysfunctions are critical in reducing drilling mechanics failures, which account for approximately 75% of non-productive time (NPT)1. Historically, surface parameters have been used to limit these failures and optimize drilling operations; however, the use of surface data has been proven to be ineffective for the following reasons:
Lodestar’s DWD technology offers a more comprehensive solution to optimizing drilling operations by providing actual, accurate downhole dynamics data without using surface data-based calculations and with less reliance on human input. Utilizing our I-STRING together with our at-bit I-SUB allows us to collect continuous measurements throughout the drill string from the bit to the surface, facilitating data-driven, physics based solutions that help our customers to determine the root cause of failures, avoid future failures, and define ideal drilling parameters that ultimately reduce NPT and increase efficiency.
