TGS to Expand Declaration Survey in Gulf of Mexico

Norwegian seismic survey firm TGS-NOPEC Geophysical Company reported Thursday that it will expand its Declaration Multi-WAZ survey in the Mississippi Canyon and DeSoto Canyon protraction areas of the Gulf of Mexico.

The extension represents a minimum of 745 square miles of additional data to be acquired by its partner CGG using a single-pass vessel configuration derived from CGG's StagSeis technology. The technology will better image deep structural elements and improve subsalt and salt flank illumination. The extension is based on early observations from the fast-track migration of phase one of the Declaration project.

TGS Chief Operating Officer Kristian Johansen commented in a company statement:

"Expanding the survey to cover the extent of the current Lower Tertiary Norphlet fairway will provide industry-leading data for current and future exploration and development objectives."

TGS said that acquisition of the extension is expected to be completed in 2Q 2015, followed by fast-track deliverables and final imaging products in 2016.
