NEWS RELEASE

FOR RELEASE ON DECEMBER 18, 2007

UNBRIDLED ENERGY PROVIDES UPDATE ON OHIO RIVER, OHIO, USA

CALGARY-PITTSBURGH · December 18, 2007 · Unbridled Energy Corporation (TSX.V: UNE/OTCBB: UNEFF/Frankfurt: 04U) (“Unbridled” or the “Company”) provides an update on its Ohio River play in the USA.

Ohio River Play, Ohio

The Company is pleased to announce it has signed a Joint Venture Agreement and a four township (92,160 acre) Area of Mutual Interest (“AMI”) agreement with Equitable Production Company, (“Equitable”), a unit of Equitable Resources, Inc. (NYSE: EQT), to partner on drilling three horizontal test wells in Q1 2008 in the Devonian Shales in south central Ohio.  Equitable is one of the largest drilling and production companies in the Appalachian Basin with extensive experience in drilling horizontal shale wells in Kentucky.  The agreement requires Equitable to invest up to $1.8 million to drill, complete, and test three horizontal wells on Unbridled’s approximate 23,000 acre land position.  Equitable will earn a 50% working interest in Unbridled’s 100% holdings. The current well design calls for drilling 2,500 ft. laterals and performing 5 stage stimulation treatments.  The spud dates are scheduled for Q1 2008.  Unbridled, a s operator, will jointly design the drilling, completion and testing program with Equitable.

Separately, but in the vicinity of Unbridled’s lands, the Company has signed a Purchase and Sale Agreement to acquire two existing wells completed in the Clinton sandstone formation and an option to purchase an additional 2,000 acres. This transaction also includes pipeline access to sell gas from a portion of the Company’s lands with Oak Hill Processors, LLC. One of the three new horizontal wells to be drilled with Equitable will be a re-entry of one of the existing Oak Hill Clinton wells, as the Devonian Shales are uphole from the Clinton formation.  This well is connected to an existing pipeline, thus any production volumes from the shale completion can be sold immediately. The Company will roll the Oak Hill purchase into the joint venture with Equitable.

President & CEO, Joe Frantz said, “It is indeed exciting to partner with one of the premier operators in the Appalachian Basin.  Equitable brings tremendous experience in drilling successful, low cost horizontal shale wells. Both Unbridled and Equitable are enthusiastic to drill these first three test wells. Schlumberger Data and Consulting Services has estimated a discovered resource in the shales of over 300 Bcf within the Company’s acreage. Subsequent to acquiring these lands, the general area has undergone intense leasing and testing as several operators have drilled or plan to soon drill shale test wells in and around Unbridled’s acreage. A large Appalachian Basin operator is now claiming success in recent horizontal shale wells just to the south in West Virginia.  The Clinton sandstone is also prospective across the acreage and has been productive in numerous older wells within the AMI. If successful, Unbridle d and Equitable could drill almost 300 horizontal wells on our existing acreage as well as substantially grow our land position.”

The Company also announced the resignation of Dr. Bob Mummery from the Company’s Board of Directors due to his concerns that his personal consulting business might give rise to future conflicts of interest with the Company’s joint project operations.  “The Company is currently in discussions with various qualified professionals to fill the resulting vacancy on the Board. We thank Dr. Mummery for all of his contributions to Unbridled Energy and wish him all the best in his future business endeavors," said Craig Steinke, Unbridled’s Chairman.
