SELECTING OPTIMAL DESIGN OF A HORIZONTAL WELL BY NUMERICAL MODELING

Abstract

Computer aided design of a horizontal well without flush tubes providing optimal operating conditions with regard to varying pressure along horizontal well length, to the presence of deviated and slant segments is considered. As a result a well-head pressure - flow rate plot is computed. Allowable values of bottom-hole pressure, of horizontal segment lengths and diameters that ensure transport of solid particles are taken into account when building well-head pressure - flow rate plot.
