Review of Horizontal Well Productivity Formulae Study

Abstract

Abstract: Wide application of horizontal drilling at home and abroad allowed it to be concerned about and focused on its productivity formulae studies.Since 1940s, a series of related formulae have been proposed, with more and more practicable usage after continuous modification.This paper reviews the progress of the horizontal wells' productivity formulae and methods studies, and presents the simplified conditions and applied ranges for the various formulae.Finally, based on the imperfections of them, the suggestions for further studies are given herein.

Key words: horizontal well, productivity, formula, permeability, anisotropy
