Comesa Taps Sercel for Unite Cable-Free Acquisition System in Mexico


CGGVeritas announced that its subsidiary Sercel has been awarded a contract by Compania Mexicana de Exploraciones S.A de C.V. (Comesa) for the purchase of a Unite cable-free acquisition system that will be used to carry out multiple seismic projects for Pemex in southern Mexico.

As a result of multiple successful field tests carried out in 2008, Comesa plans to deploy the majority of the 8,000-channel spread in autonomous mode, with data being stored in non-volatile memory in the field units. In addition, data from a substantial number of units will be acquired via the Unite system's highly advanced proprietary WLAN technology to allow real-time signal analysis. The Unite system allows greater flexibility in difficult terrain, sensitive environments or urban zones thanks to the reduction of system weight and no requirement for cable deployment.

Starting in 2002, Comesa has been upgrading its land acquisition crews with Sercel 408UL and 428XL equipment, and plans to further standardize its equipment with state-of-the-art Sercel recording systems.

Sercel added the Unite cable-free system to its portfolio of industry-leading seismic acquisition products in order to address the growing demands of the geophysical industry for large channel counts in difficult environments and total flexibility in layout and telemetry modes.
