PREDICTIVE VIBRATION MAPPING


Empowered by DrillScan® physics-based modeling software, Predictive Vibration Mapping is a swift methodology for informing the driller’s roadmaps of resonant RPMs, mitigating downhole vibration and improving overall drilling performance. The physics-based analysis allows multiple-step computations to identify axial and torsional vibration through the entire drillstring length, while providing visibility to lateral vibration for the effective length between the bit and the first point of contact in the wellbore. Incorporating Predictive Vibration Mapping results can significantly enhance set point management workflows during planning, in real-time, and road mapping by providing rapid and precise modelling results to predict critical RPM ranges for various types of bottomhole assemblies (BHAs).

SOLUTION

H&P recommended the implementation of Predictive Vibration Mapping, a solution that includes two key phases of deliverables: Phase 1: Physics-based surface RPM recommendations aimed at avoiding vibration issues. Phase 2: After each hole section is completed, a second report is generated to assess the actual RPM and the resulting vibration levels. This model considers the BHA components, WOB, mud weight, trajectory, flow rate and mud motor configuration to produce a tailored recommendation for each hole section.

OPERATOR OUTCOME

Predictive Vibration Mapping was implemented across 50 hole sections on 9 rigs, with performance data compared to 50 hole sections from the same rigs prior to implementation. On average, the service resulted in the savings of approximately one run every three wells. This equates to a cost savings of $2,000 per day, based on average trip NPT (Non-Productive Time) and spread rates.

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...
