What are borehole rigs? According to Wikipedia “A Borehole rig is a machine that creates holes in the earth’s subsurface. Borehole rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers.
Borehole rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells.
Borehole rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called ‘offshore oil rigs’ even if they don’t contain a drilling rig). The term “rig” therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth’s crust.”
Small to medium-sized borehole rigs are mobile, such as those used in mineral exploration drilling, blast-hole, Boreholes and environmental investigations.
Larger rigs are capable of drilling through thousands of metres of the Earth’s crust, using large “mud pumps” to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the “cuttings” while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe.
Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.
Borehole Companies portable borehole rigs are available with a professional drilling team to achieve your drilling requirements quickly and efficiently.
Anyone with in South Africa can drill a borehole on their private land and extract 20,000ltr/day, without an extraction license.
Borehole Companies have drilled many Boreholes across the country, domestic supply for your home, farms, golf courses, livery yards or just to top up your pond or water your garden.
Borehole Companies follows the BWA borehole drilling practices, Borehole drilling companies’ boreholes are drilled and completed with PVC water well casing, gravel packed over the screens and bentonite to surface to stop any surface contamination into your aquifer, on completion a manhole and wellhead will be installed.
Also, at completion of the borehole, borehole companies flow tests the borehole, to clean the water and confirm yield.
