This Horizontal Directional Frac-out Contingency Plan provides specific procedures and steps to contain the inadvertent releases of drilling mud (frac-outs) for water bodies that are crossed using horizontal direction drilling (HDD) techniques. 1 . FRAC-OUT CONTINGENCY PLAN
Horizontal directional drilling (HDD) is a steerable trenchless drilling method. Operators use a surface-launched drilling rig to drill a horizontal hole beneath obstacles on the surface. Find out how HDD works and its advantages over other forms of drilling. You'll be ready to tackle your next drilling project.
In order to accurately design and cost a horizontal directional drilling (HDD) crossing, it is highly recommended that a geotechnical investigation is carried out close to the prescribed bore route, preferably to a depth exceeding that of the initial bore design. ...
