Abstract
The Momotombo geothermal field in Nicaragua was investigated in three exploration stages, using a number of geophysical technique. Stage 1 of the investigations by Texas Instruments, Inc., (1970) located and delineated a potential geothermal field, with the dipole mapping surveys and electromagnetic soundings being most effective Stage 2 of the investigations, performed in 1973 by eh United Nations Development Program (UNDP), outlined the resistivity anomalies in the area west of the previously selected field; Schlumberger VES soundings and constant depth profiling (SCDP) proved most useful. During Stage 3 of the investigations, Electroconsult (ELC) performed 20 additional Schlumberger VES soundings as part of the 1975 plant feasibility studies. Results of these geophysical techniques are summarized and their effectiveness briefly discussed.
