Engineering and Design. Horizontal Directional Drilling for Environmental Applications.

摘要

The purpose of this letter is to raise the awareness of horizontal well technology, identify Hazardous, Toxic, and Radioactive Waste (HTRW) applications for horizontal drilling, and call attention to the Environmental Protection Agency Manual (EPA) 'Alternative Methods for Fluid Delivery and Recovery (EPA/625/R-94/003).' This manual describes four alternative methods for fluid delivery and recovery - horizontal wells, slant wells, induced fractures, and trenches. For the purpose of this letter, the emphasis will be on horizontal directional drilling (HDD) as it relates to the installation of horizontal environmental wells.
