Completion Design to Remove and/or Replace the Existing Completion in a Well and in Single Trip

Abstract

The aim of this paper is to propose a completion design to remove and/or replace the existing completion in a well named "X" (for confidential reasons) in a single trip. To reach the goal, the metallurgy and seals of the equipment must be selected by taking in consideration their working pressure and temperature. The best completion method must be chosen amongst others. The data used are well trajectory, particle size distribution, the reservoir data including temperature profiles, pressure, productivity index, water cuts, sand production volumes, formation damage, formation permeability, reservoir thickness and fluid properties. The completion schematic is drawn using Lip-Draw 2017, and the summary installation procedure is explained. The results show that the most appropriate materials were found to be an alloy with 13 % of chromium as metallurgy and hydrogenated nitrile for sealing elements due to the presence of H2S and CO2. For this case, the best completion method is filtrex. By using the filtrex method, the payback period is short and possibility to perform remedial sand control in a single trip while saving rig time. Filtrex method is more economical in this case than chemical and mechanical methods. For the others wells in the same field, similar completion design must be done.
