Project Profile
Value: Undisclosed
Location: Campeche Sound, Mexico
Reserves: 553 MMbo
Water Depth: 125 metres
Discovery Date: June 2008
Start-up Year: 3Q 2013
Ayatsil is a heavy oil field located in the waters of the Campeche Sound, near the massive producer Cantarell. Expected to boost production for the country by 150,000 bopd, reserve estimates for Ayatsil put the size of the field at 553 MMbo. Discovered in June 2008, the Ayatsil DL1 exploration well was drilled by Diamond Offshore\'s Ocean New Era semisub. Immediately following this discovery, the Ocean New Era then drilled the Tekel-1 exploration well nearby the Ayatsil field in 410 feet (125 metres) of water. Tekel-1 resulted in another heavy oil discovery, confirming Ayatsil as a promising development. The Tekel-1 well is expected to enhance the Ayatsil field with an additional 100 MMbo, as well as gas reserves. In June 2009, it was believed that Pemex would soon tender bids for companies interested in fabricating the platforms that will develop the Ayatsil field. Additional reports suggest that the company might hire an FPSO to produce the heavy oil reserves at Ayatsil. Scheduled to come on-stream sometime in 2011 or 2012, the Ayatsil heavy oil field is expected to supplement waning Mexican production from the massive Cantarell and Ku Maloob Zaap.
