A new drilling performance benchmarking: ROP indexing methodology

The performance efficiency in drilling oil, gas wells is eventually measured by means of comparing the time versus depth curve. However this is now being questioned, is a well drilled relatively in a shorter time period the most efficient well? Large data are now being acquired while drilling, however not all of the data available is utilized appropriately to get the big picture of the well being drilled. This research study is aiming to introduce a performance comparison methodology based on Rate of Penetration (ROP). All other operational steps other than drilling activity is routine unless there are hole problems and not dependent on formation. Drilling ROP on the other hand is a parameter that can be used to benchmark the efficiency of the drilling performances. In this research study the data of 40 wells drilled in Middle East Geomarket is used. This document describes ROP Indexing Methodology for drilling performance, and gives examples of its application from actual data. The study showed that previously used drillability performance comparisons by the industry are not feasible for benchmarking. It is obvious that he drilling industry needs a new methodology to benchmark drilling performance of the wells using advanced computers and available data being acquired from the rigs.
