Describe environmental factors that require modification to normal marine/non-marine seismic data acquisition. Include access, water depth, surface terrain, noise and obstructions. Indicate appropriate source, receiver or geometries considerations for each case. List non-conventional seismic survey types and their application. List non-conventional source and receiver types and their application. List source and receiver limitations for a transition zone seismic survey. Describe possible shooting solutions for seismic acquisition in an existing field with obstructions. Describe exploration reasons for shear wave acquisition.
