Marathon Oil has presented the MaraDrill™ project at previous Users Conferences, where they highlighted advantages of using high fidelity data from the drill rig leveraging the PI System to help mitigate common vibrational dysfunction such as stick slip, resulting in a significant increase of the rate of penetration and associated decrease in time from spud to total depth. Since first using MaraDrill™, the PI System, Coresight, and Spotfire they have been able to achieve a data-driven reduction in drilling days over the last few years in one asset, signifying a fundamental industry shift in the way some upstream operations are optimized. The next stage is to use new features of the PI System to perform surveillance on the state of the drilling operation.
Marathon Oil and OSIsoft are currently working together to implement the new Asset Based Analytics and Event Frames functionality built into the new version of PI-AF. This is being used to troubleshoot a number of Event-based issues in drilling new wells. Event Frames will be generated using Asset Based Analytics for the following events: Drilling start on new well, Rotating / Sliding, Stick Slip, Connection, Survey, Tripping In / Tripping Out, reaming Forward / Back, Circulating, On / Off Bottom and In / Out Slips. Tracking and analyzing these events will provide the ability to reduce their duration, when desired, and hence further reduce costly drilling days.
This presentation will show how Marathon and other operators drill shale wells on a pad, and the method of drilling wells in a circular fashion on the pad. It will also describe the logic to determine the well being drilled as an event frame and demonstrate use of the new Microsoft BI analytics tools to do cross rig and cross shift performance comparisons.
