THE VALUE OF PROCESS AND APPLICATION CONSISTENCY IN DRILLING AUTOMATION | HELMERICH & PAYNE


 Effectively automating drilling a stand while minimizing human variability requires a scalable control system, providing adaptability, seamless implementation, and improved operational outcomes. The system requires high- and low-level process control components to effectively control rig machinery within the bounds of the machine limit controls. By using automation sequences while engaging and disengaging the drill bit, operational states such as breakover, optimal weight on bit (WOB), steady state hookload, and zeroing become easier to distinguish.

Through consistent implementation of process automation in drilling operations, the impact on operational outcomes became evident. Analysis of bit disengagement in a series of automatically drilled stands in the lateral revealed a consistent breakover range of 18 to 22 ft. This is particularly noteworthy as breakover is typically more challenging to identify and prone to variability in manual operations.

Not all invisible lost time and variability is human related; variability due to equipment design was reduced. Torquing drillpipe connections is essential to drilling a well. Development of high spec automated floor wrenches improved make-up connection torque accuracy and consistency primarily associated with fundamental tool design. These improvements led to a connection integrity paradigm shift, reducing manual tong usage by 99%, effectively eliminating the need for high torque tongs at a wellsite, leading to improved tripping time and safety.

As drilling automation continues to evolve, the outcomes obtained through consistent process execution provide valuable insights. Additionally, this contributes to a decrease in emissions per unit of hydrocarbon production. Consistency through automation reveals new avenues for in-depth technical discussions on achieving safe and efficient drilling of progressively complex wells.

DRILLSCAN® SOFTWARE IDENTIFIES DRILLING DYSFUNCTION CAUSES IN COMPLEX, MULTILATERAL ERD WELL

Image
An operator in the North Sea faced a lower completion lock-up 800m above total depth (TD), followed by a stuck pipe event in an ERD multi-lateral well. In an initial effort to push the completion down to TD, all slack off weight and torque margin were used. Since no improvement was observed, the decision was made to pull-out. However, the string remained stuck and despite the rig efforts to free it, the lower completion had to be cut and left in hole. H&P’s DrillScan® technology team performed an in-depth post-analysis, reviewing all available data to identify what might have caused the lock-up event. The data provided was used to simulate the downhole conditions undergone by the completion with the DrillScan genuine stiff-string model. The results and conclusions pointed to string dysfunctions: suboptimal tripping and lubricating/ backreaming practices (BHA POOH) led to repeatedly exceeding the screens yield strength (lower completion RIH). H&P’s DrillScan software was a...
