| Where no cut-off switches in the boreholes exist, this results in a combination of air and water being pumped to the reservoirs. |
|
| I learned later that these boreholes, which were dug by cattle ranchers and reached down 100 meters and more, had lowered the water table. |
|
| Dating of the seismic reflectors in our dataset is hampered by the lack of accurately dated successions in deep boreholes in the region. |
|
| The seismic horizons have been calibrated using biostratigraphic and lithological data from exploration boreholes in the UK and Faroes sectors. |
|
| The only water available was in deep boreholes, which were situated in villages and carefully guarded. |
|
| The site was previously occupied by a brewery, which used boreholes to provide water. |
|
| Some residents risk their health by drawing water from boreholes and streams. |
|
| Encia workmen are punching boreholes deep into the ground to suck up oily chemicals which leaked into aquifers far beneath the surface. |
|
| Such places can offer abundant supplies of heat, usually tapped by sinking boreholes and circulating water down them to collect the heat. |
|
| This will include drilling deep boreholes at the foothills of the Auas mountains to assess the viability and storage capacity of the aquifer. |
|
| The investigation programme collected a large amount of lithological, hydrogeological and hydrochemical data from 18 boreholes up to 2000 m deep. |
|
| Tubing and foot valves are best used when dedicated to individual boreholes to avoid cross-contamination. |
|
| The tip extension would be split into sections lined with clay but Yorkshire Water is concerned contamination may leak out into nearby public water supply boreholes. |
|
| There are five boreholes and water reservoirs with 30,000 litre-capacity. |
|
| In extracting geothermal energy from hot dry rock, cold water is pumped down into the rock mass to pass through fractures and exit from a borehole or set of boreholes. |
|
| Typically hydraulic fracturing is conducted in vertical boreholes. |
|
| In more recent times, the channels of water that flow from the permanently snow-capped peaks of the high Andes have been augmented by the drilling of deep boreholes. |
|
| Gleneagles Hotel has managed to get a massive reduction in its water bill after threatening to dig boreholes in its grounds and create its own private water supply. |
|
| A reverse function makes easier retrieval of screws from tight boreholes. |
|
| Tenders are invited for Construction of monitoring boreholes at WIP Delay Tank site and RSMS site BARC, Trombay, Mumbai. |
|
|
|
| About Sh513 million has been allocated by the Bungoma government for protection of water catchment areas and drilling of boreholes. |
|
| Geologists also obtain data through stratigraphy, boreholes, core samples, and ice cores. |
|
| More than 100,000 boreholes have been drilled in Namibia over the past century. |
|
| Some of the sandstones serve as aquifers into which numerous wells and boreholes have been sunk to provide local water supplies. |
|
| This can be established as a result of boreholes, of which there have been many in the Wear valley due to coal mining. |
|
| Today, the only visible remnants of the mines are disused shafts and boreholes. |
|
| A combination of gravity anomaly data and boreholes has permitted geologists to work out the shape of this pluton. |
|
| Many boreholes are also encased in iron, which prevents conductivity measurements, but not prompt gamma neutron activation analysis. |
|
| These are designed to reduce septic tank pollution of rivers, lakes and coastal waters, as well as private water supplies such as wells, boreholes and springs. |
