Challenge
This was a detailed 3D study covering a variety of desert terrains including sand dunes and subkhat (salt) strip. There was also the added challenge of a wilderness reserve and a military firing range.
Summer-time temperatures regularly exceeded the mid-40s Cº so management of heat-related stress was essential for all field workers.
The aim was to acquire a high quality full azimuth dataset at a reasonable cost to merge with previously acquired 3D data in adjacent areas.
Solution
The programme used modern high production techniques to acquire the seismic data. This included the use of up to 14 seismic vibrators operating independently in “slip sweep” mode in order to maximise production. In a subsequent phase of the programme the crew started night-time operations to further increase production rates.
