DrillBest – GEOLOG’s drilling performance optimization service provides a simple solution to highlight key areas of improvement with data collected independently through quality controlled surface measurements. DrillBest delivers tailor-made reports highlighting key data points in order to improve drilling efficiency, identify invisible non productive time and root causes while defining new KPIs. The results are achieved through close collaboration between GEOLOG and Client.
DrillBest service can be provided on-site, at client offices or performed remotely for offshore as well as onshore projects. Predrill analysis can be performed utilizing historical data to establish KPIs and enhance performance on successive wells. The service is able to deliver maximum benefits when the learnings are applied to subsequent wells to reduce overall project costs.
Customer requested a detailed analysis of the WOB to WOB time in order to identify and quantify the amount of time spent on each operation. After careful evaluation of the data, the well program was revised. The revised program drastically reduced the reaming and back reaming time. This resulted in the average time for a connection to be reduced from 39 min/conn to 19 min/conn. For the whole 12 ¼” phase 36 hours of rig time was saved.
