First experience of onshore seismic survey with explosive sources in Cambodia

Abstract

JOGMEC/MOECO carried out an onshore seismic survey with explosive sources in 2012 in Cambodia.The project was executed under the Basic Agreement for the Study and Survey Program in Block XVII onshore Cambodia between JOGMEC and CNPA. This was the first experience of seismic data acquisition with explosives in Cambodia.Therefore, there were a lot of issues to be resolved before the field work was launched. One of most serious issues was the implementation of safe operations in a Mine/UXO contaminated eld. Other issues were a lack of regulations in Cambodia, education of non-experienced Cambodian people including both government staffs and local residents, explosive management and so on. Firstly JOGMEC/MOECO hired excellent Cambodian national staffs and further educated on seismic surveys. Then, they seriously and actively worked for communications with both government staffs and local residents. Such efforts resulted in good cooperation with all relevant parties even though unexpected procedures caused delays in the schedule. Finally, the seismic survey was successfully completed and no lost time for injury was recorded. A lot of knowledge on the seismic survey has been accumulated for all relevant parties through this experience. The procedures established by JOGMEC/MOECO through this survey will be one of the standards for onshore seismic data acquisitions in Cambodia.
