    Completion Techniques

        by Abass Radhi Abbas 1.General Communication between the formation and the wellbore will directly affect the productivity of the well. Factors such as hydrocarbon saturation, porosity, permeability, fluid properties and geometry can be measured or inferred from the measurements but they cannot usually be controlled. By contrast, completion can be controlled and thus affect well performance. During the drilling, logging and testing phase of the well, valuable information will have been gained and the relevant completion technique chosen. There are two main categories of completions to consider with, of course, many variations; –  Open hole Completions. – Cased Hole Completions. 1.1.Openhole Completions An open hole completion is when…
