Abstract Analysis of the well test data from ten (10) deep wells completed in Olkaria West is presented. The high temperatures are distributed along the Olkaria fault zone or Olkaria fracture zone. The upflow of the system is suggested to be to the west or North west of OW-301, based on the pressure and temperature contours. Permeability and hence fluid movement is mainly along contact surfaces between pyroclastics and rhyolites, fractures within the rhyolites and along major fault zones such as the ones around OW-301. The output from the wells in Olkaria West is low except for OW-201 and OW-301 but with higher content in the discharge fluids than observed in the wells from Olkaria East and North East. The proven resource area covers about probably capable of supporting about 150 power production for 25 years. Further drilling is required to establish the extent of the proven resource area to the west and north west of OW-301and OW-101.
