  2. Olkaria IV Geothermal Power Station - Wikipedia

    en.wikipedia.org/wiki/Olkaria_IV_Geothermal...

    Olkaria IV Geothermal Power Station was commissioned by Uhuru Kenyatta, the president of Kenya, on 22 October 2014. [11] The 140 megawatts (187,743 hp) power station cost KSh11.5 billion (US$126.5 million) to build, co-financed by the World Bank , the Kenya government and the European Investment Bank .

  3. Geothermal power in Kenya - Wikipedia

    en.wikipedia.org/wiki/Geothermal_power_in_Kenya

    By 2030 Kenya aims to have 5,530 MW of geothermal power or 51% of total capacity. [5] This will make it Kenya's largest source of clean energy by 2030. Geothermal power plants have a prominent place in Kenya's overarching development plans. These include the Vision 2030, the NCCAP, and the current ‘5000+ MW in 40 months initiative’.

  4. Borehole mining - Wikipedia

    en.wikipedia.org/wiki/Borehole_mining

    Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...

  5. Extended reach drilling - Wikipedia

    en.wikipedia.org/wiki/Extended_Reach_Drilling

    What exactly determines a well to be "extended reach" varies over time and location with the development of technologies and of experiences. [ 2 ] On 24 April 2015 the world's longest borehole was drilled and completed from the Orlan Platform in the Chayvo Field, Sakhalin-1 Project with a total measured depth of 13,500 m (44,294 ft) and a ...

  6. Baptist well drilling - Wikipedia

    en.wikipedia.org/wiki/Baptist_well_drilling

    Baptist well drilling diagram in Spanish. Baptist well drilling is a very simple, manual method to drill water wells. The Baptist drilling rig can be built in any ordinary arc welding workshop and materials for a basic version costs about 150 US dollars (2006 prices). In suitable conditions, boreholes over 100 m deep have been drilled with this ...

  7. Underground pneumatic boring - Wikipedia

    en.wikipedia.org/wiki/Underground_pneumatic_boring

    Tool speed is controlled by manipulating the air supply to the tool. This air supply valve is outside the tool and remains accessible to the operator. As the tool pounds through the ground, it compresses the soil. This compaction maintains the same diameter as the tool and leaves the borehole through which the product is passed.

  8. Drill cuttings - Wikipedia

    en.wikipedia.org/wiki/Drill_cuttings

    Drill cuttings [1] are broken bits of solid material removed from a borehole drilled by rotary, percussion, or auger methods and brought to the surface in the drilling mud. Boreholes drilled in this way include oil or gas wells, water wells, and holes drilled for geotechnical investigations or mineral exploration. [2]

  9. Geothermal exploration - Wikipedia

    en.wikipedia.org/wiki/Geothermal_Exploration

    This information allows for higher success rates in geothermal plant production as well as lower drilling costs. As much as 42% of all expenses associated with geothermal energy production can be attributed to exploration. These costs are mostly from drilling operations necessary to confirm or deny viable geothermal regions. [4]
