Diploma in Geophysical Exploration

The Diploma in Geophysical Exploration is a Level 6 TVET programme offered at Kabete National Polytechnic and KenGen Geothermal Training Centre in Kenya. The programme trains students in geophysical methods used to explore, characterise, and monitor subsurface resources including geothermal reservoirs, minerals, and groundwater.

The curriculum covers seismic methods, magnetic surveying, gravity surveying, electrical resistivity, electromagnetic techniques, well logging, data acquisition and processing, and geophysical instrumentation. Students learn to operate specialised geophysical equipment and interpret subsurface data for resource assessment.

Students develop competencies in field survey operations, geophysical data collection, equipment maintenance, data processing using specialised software, and interpretation of geophysical anomalies. The programme combines classroom lectures, laboratory work, field exercises at active geothermal sites, and industrial attachment.

Graduates pursue careers as geophysics technicians, assistant geophysicists, seismic data analysts, and survey technicians at organisations such as KenGen, Geothermal Development Company (GDC), oil exploration companies, mining firms, and environmental consulting agencies across Kenya and the East African region.

The programme is offered at Kabete National Polytechnic (KSH 67,189 per year, KNQF Level 6, 280 credits) and KenGen Geothermal Training Centre in Naivasha (KSH 35,000 per semester). Both institutions are accredited by TVETA and the curriculum is developed under the CDACC competency-based framework.

Admission requires a KCSE mean grade of C- (Minus) with C- in Physics, Mathematics, and Geography, or a Level 5 Certificate in Geology Technology or a related field. The programme includes industrial attachment at geothermal, mining, or oil exploration sites.

A day as a student

A typical day combines classroom lectures on geophysical theory, laboratory work with geophysical instruments, and field exercises. Morning sessions cover seismic, magnetic, and gravity methods theory, while afternoons involve practical field surveys, equipment operation, data acquisition, and computer-based data processing. Students at KenGen GTC also participate in field exercises at active geothermal sites in Olkaria.

The trade offs

In its favour

Kenya is a leading geothermal energy producer in Africa, creating strong demand for geophysics technicians.
Programme offers hands-on training at active geothermal sites through KenGen GTC.
Graduates can work in diverse sectors including geothermal, oil, mining, and groundwater exploration.
KenGen GTC is a World Bank-supported Regional Centre of Excellence with industry-recognised certification.

Against it

Field work often involves working in remote areas and harsh environmental conditions.
The programme is highly specialised, limiting career flexibility outside the geosciences sector.
Only two institutions in Kenya offer this programme, limiting geographic access.
Career advancement to geophysicist roles typically requires a university degree.

What it costs
