Abstract

Optimizing completions in deviated and extended reach wells is a key to safe drilling and optimum production, particularly in complex terrain and formations. This work summarizes the systematic methodology and engineering process employed to identify and refine the highly effective completions solution used in ERW completion system and install highly productive and robust hard wares in horizontal and Extended Reach Wells for Oil and Gas. A case study of an offshore project was presented and discussed. The unique completion design, pre-project evaluation and the integrated effort undertaken to firstly, minimize completion and formation damage. Secondly, maximize gravel placement and sand control method .Thirdly, to maximize filter cake removal efficiencies. The importance of completions technologies was identified and a robust tool was developed .More importantly, the ways of deploying these tools to achieve optimal performance in ERW’s completions was done. The application of the whole system will allow existing constraints to be challenged and overcome successfully; these achievements was possible, by applying sound practical engineering principle and continuous optimization, with respect to the rig and environmental limitation space and rig capacity.
