MDA continues to support Mexico's largest oil company with advanced RADARSAT products

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that it has signed an additional contract valued at US$751,000 with Petroleos Mexicanos (PEMEX) for the continued monitoring of natural oil seeps and spills in the Gulf of Mexico using advanced RADARSAT satellite data. This is the fifth contract that PEMEX has signed with MDA since 2000.

The RADARSAT data contains critical information to aid PEMEX in the exploration and development of its offshore oil production activities. MDA also provides analytical reports that identify clusters of naturally occurring oil slicks that represent positive indicators of present-day hydrocarbon generation and migration. This information is used to enhance the performance of exploration activities in the Gulf of Mexico.

PEMEX has also been using RADARSAT data operationally for the environmental monitoring of oil slicks in the Gulf of Mexico for over a decade. In this time RADARSAT data has become fully integrated into PEMEX's maritime monitoring program to increase its environmental performance and response strategy.

Dave Hargreaves, the vice president responsible for this business said, ‘PEMEX represents one of the world’s largest oil companies. Their ongoing and expanding work with MDA is a great endorsement of our level of service and the value PEMEX receives from the information products MDA delivers.’
