Acidizing horizontal wells

Jump to navigation Jump to search

Horizontal wells are special cases, which have been covered by Frick and Economides. [1] They emphasize how damage control and removal is just as important in horizontal wells as in vertical completions. Moderate damage can reduce horizontal well productivity to that below the productivity of an undamaged vertical well. The authors provide a stimulation technique employing coiled tubing. They also provide a design strategy for calculating volumes of acid required and the rate of coiled-tubing withdrawal during acid placement. A method of optimization for completion and stimulation of horizontal wells is also presented. Other papers have further advanced the planning, design, diversion, execution, and evaluation of acidizing horizontal wells employing similar methods to those used in vertical wells. [2][3]
