2. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   Submersible pump cables are electrical conductors designed for use in wet ground or under water, with types specialized for pump environmental conditions. [5] [6] [7] A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions.

3. Water well pump - Wikipedia

   en.wikipedia.org/wiki/Water_well_pump

   Deep well pumps extract groundwater from subterranean aquifers, offering a reliable source of water independent of municipal networks. These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought.

4. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.

5. Dewatering - Wikipedia

   en.wikipedia.org/wiki/Dewatering

   A deep well typically consists of a borehole fitted with a slotted liner and an electric submersible pump. As water is pumped from a deep well, a hydraulic gradient is formed and water flows into the well forming a cone of depression around the well in which there is little or no water remaining in the pore spaces of the surrounding soil.

6. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   Deep well hand pumps are used for high lifts of more than 15 m. The weight of the column of water is too great to be lifted directly and some form of mechanical advantage system such as a lever or flywheel is used. High lift pumps need to be stronger and sturdier to cope with the extra stresses.

7. Deepwater drilling - Wikipedia

   en.wikipedia.org/wiki/Deepwater_drilling

   Deepwater drilling, [1] or deep well drilling, [2] is the process of creating holes in the Earth's crust using a drilling rig for oil extraction under the deep sea. There are approximately 3400 deepwater wells in the Gulf of Mexico with depths greater than 150 meters.

8. Blowout (well drilling) - Wikipedia

   A well control company then will need to extinguish the well fire or cap the well, and replace the casing head and other surface equipment. If the flowing gas contains poisonous hydrogen sulfide , the oil operator might decide to ignite the stream to convert this to less hazardous substances.

9. Airlift pump - Wikipedia

   en.wikipedia.org/wiki/Airlift_pump

   (The compressor is on the surface and no mechanical parts are needed in the well). However airlift wells must be much deeper than the water table to allow for submergence. Air is generally pumped at least as deep under the water as the water is to be lifted. (If the water table is 50 ft below, the air should be pumped 100 feet deep).
