Operators have established procedural requirements as part of their HSE, risk and cost control policies. Automating procedural compliance enables real-time operations oversight while reducing risks associated with manual processes. A novel technique was developed and implemented to automatically check rigs’ procedural compliance with an operator's guidelines and alert users in real time.
The following procedures have been developed and deployed: zeroing of weight on bit and mud motor differential pressure for more accurate ROP (rate of penetration) optimization, lowering BHA (bottom hole assembly) back to bottom with reduced RPM, connection practice procedure, and capturing steady-state hook-load values for improved torque and drag monitoring. Each procedure was identified to influence future optimization efforts to a varying degree. Consider if the weight on bit is not zeroed properly it can cause incorrect driller's road-map recommendations for new wells.
The framework has been extensively tested and refined with the assistance of a Permian operator until it reached an acceptable accuracy: 95% for back-to-bottom procedure, 99% for zeroing WOB (weight on bit), and 90% for zeroing DIFF (differential pressure). Reports have been generated to display the statistics of the compliance for each rig and crew. A Permian operator, who has field tested the procedural compliance application, estimates that it will save millions of dollars per year by avoiding costly equipment damage as well as from significant time savings by standardizing a back-to-bottom procedure.
Real-time procedural compliance is a novel technique to check whether the rig personnel follow the operator's procedures. It has a flexible back-end interpreter, and each procedure is provided separately. This ensures the procedure is not attached to the original code and can be easily modified. Through the use of a real-time compliance engine, every operator can load their respective procedures and check for compliance in real-time.
