HOUSTON, Feb. 25 -- Contango Oil & Gas Co., Houston, announced that a dredge contracted by the Army Corps of Engineers in the Atchafalaya River Channel on Feb. 24 ruptured its 20-in. OD pipeline extending between its Eugene Island 11 gathering platform and the Eugene Island 63 platform from which its production moves to shore.

The ruptured pipeline transports natural gas production from Contango’s four Mary Rose wells, its Dutch No. 4 well, and its Eloise North well. All six wells were immediately shut-in. Contango provided notice of force majeure to all applicable parties.

At the time of the incident, the pipeline was flowing 125 MMcfd of gas. Contango’s production from Dutch Nos. 1, 2, and 3 wells goes to the EI-24 platform and was unaffected, flowing at 27 MMcfd of gas, net to Contango.

The company said no serious injuries or environmental damage had occurred as a result of the rupture. Repair vessels and a diving crew are en-route to the location to assess the extent of pipeline damage to our pipeline. Contango expected to have divers on-scene Feb. 25 to provide a damage estimate, after which cost and times estimates for repair could be made.

Contango began production at Mary Rose in 2008.

The Resilient Oilfield in the Internet of Things World

Tue, Sep 22, 2015

As we hear about the hype surrounding the Internet of Things, the oil and gas industry is questioning what is different than what is already being done. What is new?  Using sensors and connecting devices is nothing new to our mode of business and in many ways the industry exemplifies many principles of an industrial internet of things. How does the Internet of Things impact the oil and gas industry?

Prolific instrumentation and automation digitized the industry and has changed the approach to business models calling for a systems led approach.  Resilient Systems have the ability to adapt to changing circumstances while maintaining their central purpose.  A resilient system, such as Maximo, allows an asset intensive organization to leverage connected devices by merging real-time asset information with other critical asset information and using that information to create a more agile organization.  

Join this webcast, sponsored by IBM, to learn how about Internet of Things capabilities and resilient systems are impacting the landscape of the oil and gas industry.
