Seismic Refraction Survey in Kenya, Uganda, Tanzania, Rwanda, Somalia, Sudan, DRC Congo, Mozambique, Zambia, and the rest of the East African region.
A seismic survey is a technique used to study the structure and composition of the Earth's subsurface by creating and recording sound waves. This is done by generating a series of controlled vibrations or "shots" on the ground or in the water and recording the resulting seismic waves using an array of sensors called geophones. By analyzing the time it takes for the waves to travel through different layers of rock and other geological structures, geologists can create detailed 3D images of the subsurface, which are useful for a variety of applications such as mineral exploration, oil and gas exploration, and earthquake monitoring. Seismic surveys are commonly used in the energy industry to locate and evaluate potential oil and gas reserves.
- Reflection Seismology: This technique involves generating a seismic source (such as an explosive charge or a specialized vibrator truck) at the surface of the earth, which sends seismic waves through the subsurface. These waves reflect off different geological layers and are detected by geophones at the surface. By analyzing the travel times and amplitudes of the reflected waves, geoscientists can construct a detailed image of the subsurface.
- Refraction Seismology: This technique is used to determine the thickness and depth of the subsurface layers. It involves generating a seismic source and measuring the travel times of the seismic waves that are refracted (bent) by different layers of rock. By analyzing the travel times and velocities of the refracted waves, geoscientists can estimate the depth and thickness of the subsurface layers.
Both techniques can be conducted on land or in marine environments. In marine environments, air guns or specialized boomer equipment can be used to generate the seismic source, and hydrophones or streamers can be used to detect the reflected or refracted waves. The resulting data can be used to create detailed 2D or 3D images of the subsurface, which can be analyzed to identify potential reserves of oil, gas, or minerals.
- Oil and gas companies: Seismic surveys are widely used in the oil and gas industry to locate and evaluate potential reserves of oil and gas.
- Mining companies: Seismic surveys can also be used in the mining industry to identify mineral deposits and assess the potential for commercial extraction.
- Environmental consulting firms: Seismic surveys can be used to support environmental studies, such as monitoring the effects of human activity on the subsurface or identifying potential hazards related to subsurface geology.
- Research institutions: Seismic surveys are also used in academic research to study the structure and composition of the Earth's subsurface.
