Many drill rigs that donât employ the Geoprobe drilling machine simply wonât work in areas where the Geoprobe direct push drilling machines actually excel. The Geoprobe machine accommodates several sampling tools that can be readily attached to the boring rods in order to collect groundwater samples, soil and soil-gas samples.
In geotechnical engineering, drilling fluid is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. Liquid drilling fluid is often called drilling mud. The three main categories of drilling fluids are water-based muds (which can be dispersed and non-dispersed), non-aqueous muds, usually called oil-based mud, and gaseous drilling fluid, in which a wide range of gases can be used.
