A borehole is the generalised term for any narrow shaft drilled in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water or other liquid (such as petroleum) or gases (such as natural gas), as part of a geotechnical investigation or environmental site assessment, for mineral exploration, or as a pilot hole for
Kefid · However as drilling contractors we are obliged to provide the British Geological Survey (BGS) with information relating to any new borehole over 15mtrs. Can I drink the water? Almost every borehole can provide drinking water although in some cases filtration or treatment may be required to bring the water to drinking standards.
Kefid · A borehole is an ancient technique dating back over three thousand years. It originated in China where bits of bamboo attached to a heavy weight were used to drill water wells. There are two main approaches to boreholes these days : - Manual drilling …
Kefid · Boreholes drilled for the purposes of site investigations. In-situ borehole measurements and results of geotechnical laboratory tests are taken on samples to gain an understanding of the engineering properties of rocks and soils. Several geotechnical in-situ tests do not rely on borehole. In UK, for

Kefid · The Borehole module of GMS can be used to visualize boreholes created from drilling logs or synthetic boreholes created manually and to construct three-dimensional cross sections between boreholes. These cross sections show the soil stratigraphy between two boreholes. Borehole data can be imported or created in GMS.
Sonic drilling . Sonic drilling involves sending high frequency mechanical oscillations down a drill string to the bit. These vibrations fluidize soil particles at the face of the bit which allows for easy penetration through most geological formations where other techniques may be less successful, particularly where the strata is varied.
Once the drilling and casing of a water production borehole is completed, our experts then develop the borehole. Development, or flushing of the water production borehole is of paramount importance as this gets rid of most of the solids that come into the borehole during the drilling process.
Kefid · A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth''s subsurface. Drilling 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.

Kefid · The Kola Superdeep Borehole (Template:Lang-ru) is the result of a scientific drilling project of the former USSR. The project attempted to drill as deep as possible into the Earth''s crust. Drilling began on 24 May 1970 on the Kola Peninsula, using the Uralmash-4E, and later the Uralmash-15000 series drilling …
Kefid · Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.Process · Material · Related processes · See also · References · External links

This method involves pulling down borehole casing during the drilling process. This keeps the borehole from collapsing, and can also enable you to drill through hard formations. Construction Borehole construction is another big contributor to cost. It is very important that a …
Borehole Drilling. Blue River Drilling SA offers a turnkey solution to all you domestic and commercial borehole drilling requirements. Considering the escalating water costs, drilling a borehole for a domestic home or commercial property is becoming a more viable and cost effective solution for water supply.
Drilling. Generally we use rotary DTH hammer drilling, using top drive hydraulic rigs with high pressure air flush, and foam injection where necessary. We are able to drill up to 230m in depth through most formations up to 12-inch diameter. Once the well is proved viable during the drilling process, casing is installed to drilled depth.

Kefid · Borehole Mining (BHM) is a remote operated method of extraction of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jets (hydraulicking).This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes.
Borehole for Site Investigation- Borehole are basically used for taking soil sample from different places in the proposed site for construction. Borehole logs are then plotted from that data to estimate the soil profile for that region and soil ob
