Potential Using of OEE in Evaluating the Operational Performance of Workover Activities

The aim of this paper is to develop OEE as a metric and a measure to monitor the actual performance of workover activities. Improved efficiency can be achieved through the effective management of effort to improve productivity. The main purpose of the OEE results is to evaluate essential data against where decisions may be made. The OEE monitors the actual performance of workover relative to its performance capabilities under optimal workover conditions. An attempt could be made to enhance the efficiencies of the workover activities rigs in the Sarir Oilfield. A case study approach was adopted for the data collection, which was undertaken over an eight-month period, and utilized a number of collection techniques including, participant observation, daily report analysis, and work experience. The concept discussed in this paper is providing the basis for developing a more uniform method of evaluating rig performance. It should result in more efficient rig operations. This method of calculating rig efficiency provides the practical measure of the workover performance which can aid in rig procedures negotiation and rig selection. The improvement opportunities in workover procedures have been identified based on OEE results for improvement and new variations of these measures can be implemented for other workover at Oilfields that use the same artificial lift method.
