Aug. 2011 - In June 2011, ATP O&G completed and returned to production the Missippi Canyon Block 711 No. 5 well, making it the six well to come online at Gomez. The DOCD (Development Drilling Plan) for MC Block 711 No. 9 and MC Block 711 No. 10 were submitted to the governmental agency, and upon approval, ATP expects to commence drilling on the wells with first production expected in mid-2012.

Original proved reserve estimates of the Gomez Hub accounted for 14.8 MMboe, and since online, the Hub has produced gross volumes of 24.8 MMboe. Located in the deepwater Gulf of Mexico, the Gomez project consists of one field, Gomez, and three satellite fields, Anduin, Anduin West and Gladden. The four fields are tied-back to the ATP Innovator platform. ATP operates Gomez Hub, and has a 100% working interest in MC 711, 710 and 755; and a 75% working interest in MC 754.

The gas pipeline, 28 miles long (45 kilometers long), has the capacity to transport 100 million cubic feet of natural gas to the Discovery Gas Pipeline. ATP will remain the operator of Mississippi Canyon Block 711 and will remain as operator of both pipelines.

Jul. 2009 - ATP announced that the ATP Innovator is the first Gulf of Mexico offshore platform to install an Automatic Dependent Surveillance-Broadcast (ADS-B) system for air traffic control to and from platforms in the Gulf of Mexico. ATP partnered with the Federal Aviation Administration (FAA) Surveillance and Broadcast Services Office, the Helicopter Association International (HAI), Gulf helicopter operators, and other offshore oil and gas companies to implement this new technology. ADS-B uses precise location data from the global satellite network to provide real-time, radar-like traffic information directly to ADS-B equipped aircraft, then transmitted to shore to the FAA and to air traffic controllers and other aircraft. In addition, the system will provide helicopter operators in the Gulf immediate access to updated weather information and other flight information services. The system on the ATP Innovator platform will be part of a larger network of systems which are set to go operational in December 2009.
