Evaluation of the Selection of Casing and Tubing Size in a Foreign Oil Field

Abstract

A procedure for determining the correspondence between production and completion engineering and casing and tubing sizes, and the related requirements of completion engineering for an oilfield in the Sahara desert is developed. Statistical analysis of the wellbore structure of a well cluster and an analysis of the current structure lead us to recommend appropriate wellbore structure systems for the oilfield. The study is of great significance for desert oilfields similar to the present oilfield, specifically in the selection of casing and tubing sizes and in the development of the wellbore structure.
