The intersect method of drilling uses two drills, one at each end of the bore's design path. One of which has a magnetic source mounted on the assembly (BHA) instead of a steering tool. The magnetic source allows the rig without the magnet to determine the distance and azimuth to the source.… View Full Term

Drilling fluid mistakes are common in trenchless construction. Often, these mistakes are made to save money. However, these cost-cutting techniques can cost companies…
In its basic components drilling mud (drilling fluid) is bentonite clay and water mixed with some polymer additives to give it the required gel strength, viscosity and…
Directional drilling has been around for some decades but it was only in the 1990s that directional drilling started being used for underground construction. Drilling…
Controlling solids in the horizontal directional drilling is an integral part of equipment maintenance. Project managers knew that disposal of the drilling fluid is both…
