TGS announces extension of Declaration project

19 February 2015OSE

ASKER, NORWAY (19 February 2015) - TGS announces the extension of its Declaration Multi-WAZ Survey in the Mississippi Canyon and DeSoto Canyon protraction areas of the Gulf of Mexico.

The extension represents a minimum 2,000 km2 of additional data to be acquired by CGG using the single pass vessel configuration derived from its StagSeisTM technology. This 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.

Kristian Johansen, COO for TGS commented that, "Expanding the survey to cover the extent of the current Jurassic Norphlet fairway will provide industry-leading data for current and future exploration and development objectives."

Acquisition of the extension is expected to be completed in Q2 2015, followed by fast track deliverables and final imaging products in 2016.



TGS provides multi-client geoscience data to oil and gas Exploration and Production companies worldwide. In addition to extensive global geophysical and geological data libraries that include multi-client seismic data, magnetic and gravity data, digital well logs, production data and directional surveys, TGS also offers advanced processing and imaging services, interpretation products, and data integration solutions.

All statements in this press release other than statements of historical fact are forward-looking statements, which are subject to a number of risks, uncertainties and assumptions that are difficult to predict, and are based upon assumptions as to future events that may not prove accurate. These factors include TGS' reliance on a cyclical industry and principal customers, TGS' ability to continue to expand markets for licensing of data, and TGS' ability to acquire and process data product at costs commensurate with profitability. Actual results may differ materially from those expected or projected in the forward-looking statements. TGS undertakes no responsibility or obligation to update or alter forward-looking statements for any reason.
