Athugasemdir: Presented at SDG Short Course I on Exploration and Development of Geothermal Resources, organized by UNU-GTP, GDC and KenGen, at Lake Bogoria and Lake Naivasha, Kenya, Nov. 10-31, 2016.
Útdráttur: The aim of geophysical exploration is to measure the earth’s physical properties in order to delineate geothermal fields, locate aquifers, site wells and provide information on which economical exploitation can be based on. During these measurements, emphasis is put on parameters that are sensitive to rock temperature, permeability, porosity and salinity of the fluids that are contained in the rock matrix. By use of all geophysical method in one field and integrating all their data in interpretation, we have been able to site deeper wells that are good producers producing up to 16MWe. We have been able to map out various structures such as intrusive rocks (possible heat source), porosity variations, faults and dyke systems. We also liaise with other departments (e.g. geology and geochemistry) so as we can combine notes and come up with a detailed accurate conceptual model of the area.
