Horizontal Drilling



As the name implies, holes are drilled in a horizontal plane for many applications such as relief holes to relieve hydrostatic water pressure, cable and pipeline ducts, mineral and soil investigation, collect wells etc. HD has made many specialized machines for these applications to suit various requirements. In many cases special drill string specifications are required to maintain hole linearity and overcome drift due to gravity. Suitable machines are HD90MKIV, HD110-3 and HD180.
