This study conducted a high-power CSEM survey in Half Moon Bay, Saudi Arabia, aiming to verify the technology and successfully detect and characterize potential economic brines in the area. By collecting, evaluating, processing, and interpreting various transmitter-receiver configurations, acquisition parameters, and passive and active EM data, the subsurface was characterized. LOTEM and FSEM configurations were proven to provide high-quality data.
We conducted an initial high-power CSEM (controlled-source electromagnetic method) survey in a coastal salt-flat area in the broader area of Half Moon Bay, in the southern part of Dammam Peninsula in the eastern province of Saudi Arabia. The primary purpose of this work was to verify the technology, but we were also able to detect and characterize potential economic brines in the study area. For a high-quality data acquisition, several transmitter-receiver configurations, different acquisition parameters, and passive and active EM data were collected, evaluated, processed, and interpreted to characterize the subsurface. The long-offset EM (LOTEM) and the focused-source EM (FSEM) were the optimum configurations due to the high-quality of the collected data. This is a starting point for using the CSEM method towards the O&G, geothermal, CO2 sequestration, groundwater, lithium brine, and other natural resources' exploration and exploitation in the Gulf countries.
