Practical Evaluation Workover Framework (PEWF) for evaluation and process improvement of Workover Rigs in the Oilfields

In this work Practical Evaluation Workover Framework (PEWF) can be defined as a procedure that provides a practical workover maintenance system for workover and production engineers in the Oilfields. This procedure involves operators and technicians in the workover rigs acting as a team to monitor the workover procedures including Electrical Submersible Pump (ESP) processes (installation and nu-installation) and reduce the production losses in the oil wells by returning the oil well to production in the right time. The model's detail and procedures are simple to use and it supports workover rigs to implement the main structures of Total productive maintenance (TPM) to improve the efficiency of the workover rig. PEWF is built on the collection and analysis of the Overall equipment effectiveness (OEE) data gathered by the workover and production engineers on the workover rig. The OEE monitors the actual performance of workover relative to its performance capabilities under optimal workover conditions. The main purpose of an OEE results is to present essential data against where decisions may be made. These measurements assist the management to evaluate progress and help production and workover engineers identify the sources of problems on ESP processes and workover rigs activities. This method of calculating rig efficiency provides the practical measure of the workover performance which can aid in rig procedures negotiation and workover rig selection.
