Contango Makes Discovery at Grand Isle 72 in the Gulf of Mexico

Contango Oil & Gas Company has made a discovery at Grand Isle 72 ("Liberty"), located approximately 25 miles offshore Louisiana in 128 feet of water.

The Grand Isle 72 #1 well was drilled to a total measured depth of 14,256 feet and the wireline logs of the well indicated the presence of hydrocarbons within four zones with approximately 140 feet of potential net pay. The lower most pay sand tested natural gas at a rate of 5 million cubic feet per day ("MMcf/d") and 14 barrels of condensate per day, based on a four hour test and 3,400 pounds per square inch (psi) of flowing tubing pressure. Production casing has been set, completion operations are underway, and the well is scheduled to commence first production prior to calendar year-end 2006. The remaining pay sands will be completed as the lower sands are depleted.

COI paid a 50% working interest through the completion and testing of the well, and has a 25% working interest thereafter. Contango Offshore Exploration LLC ("COE"), a subsidiary in which the Company owns a 76% interest, generated the prospect and was fully carried in the drilling costs through the completion and testing of the well and will have a 50% working interest thereafter. The net revenue interests to COI and COE following well completion and testing are estimated to be 20% and 40%, respectively. The net revenue interest to Contango, as a whole, will be approximately 50%. Our two third party partners each paid a 25% working interest through the completion and testing of the well, and each have a 12.5% working interest thereafter.

Kenneth R. Peak, Contango's Chairman and Chief Executive Officer, said, "We are pleased to have successfully logged an offshore discovery on our Grand Isle 72 block. The discovery is the first for our new operating subsidiary, COI. In other offshore activities, our farm-out prospect, Main Pass 221, is currently being drilled, and we expect to begin drilling our Eugene Island 10 prospect in late March 2006. We expect to begin drilling our High Island A-279 and West Delta 43 prospects before calendar year-end.

Contango is a Houston-based, independent natural gas and oil company. The Company's core business is to explore, develop, produce and acquire natural gas and oil properties primarily offshore in the Gulf of Mexico and onshore along the Gulf Coast, and in the Arkansas Fayetteville Shale. As a recent addition to our business, we now operate certain offshore prospects through our wholly-owned subsidiary, Contango Operators, Inc. ("COI"). The Company also owns a 10% interest in a limited partnership formed to develop an LNG receiving terminal in Freeport, Texas, and holds investments in companies focused on commercializing environmentally preferred energy technologies.
