Chinese Ultra-Temperature Geothermal Drilling Technology Promotes Geothermal Resource Development in Kenya China Mining Conference (18th) －* － In 2016, with rich drilling experience and advanced technology, GWDC of CNPC successfully bid for the Kenya Olkaria power station geothermal drilling project. It is the only ultra-temperature geothermal well drilling service abroad operated by Chinese company, called the first army of geothermal drilling overseas. 1. Background Now, GWDC has completed 146 geothermal wells in Kenya Olkaria block, total length was 42×104m, the longest well depth was 3650m. Discovered new deep layer. Increased 196% production compared with similar wells drilled by American company. Production of one of the wells exceeded 30WM. It is the third highest production well in the world. Winning high praise, GWDC has become a new business card for CNPC drilling overseas. －* － 1. Background Kenya is one of the most dynamic countries in the economic and social development of East Africa. The power demand is increasing about 8% per year, but supply shortage and high price of electricity has become one of the main bottlenecks which restrict the development of the national economy. Power Demand In Kenya 8% Peak of electricity demand on Kenya (MW) Electricity generation before 2010 in Kenya Geothermal power generation Oil fired power? generation ?Hydro electric generation? －* － 2. Basic situation Peak of electricity demand(MW) Kenya is located in the eastern part of Africa, East African Rift Valley going north and south vertically and horizontally, with rich geothermal resource. There are 14 geothermal blocks, potential power is 7000～10000MW。 Present situation of Kenya geothermal Distruution and potential of East African Rift Valley geothermal resources Development in Olkaria 1970: Exploration 1972: Well drilling 1976: Build power station Geothermal electric power installed capacity is 575MW Development in Olkaria －* － 2.
