Viola 3D (2C & 4C)

Description

The Viola 3D OBS infill program was designed to help delineate the producing fields which comprise both oil and gas reserves. The current production interval is a tertiary Eocene sandstone. Additional 4C data were produced to further illuminate the reservoir extent.
