Horse Hill-1 Well Drilling Update

DENVER, CO--(Marketwired - September 18, 2014) - Magellan Petroleum Corporation ("Magellan" or the "Company") (NASDAQ: MPET) today provided an update on the status of drilling at the Horse Hill-1 well in the Weald Basin, onshore UK. The well spudded on September 3, 2014, and surface casing has been set and cemented to a depth of 84 ft. Drilling on the intermediate section of the wellbore is expected to commence imminently, and, approximately six weeks thereafter, TD is expected to be reached at 8,680 feet.

The Horse Hill-1 well, which is designed as a near vertical well that will not be hydraulically fractured, is targeting a conventional Triassic-aged gas target. In addition, the well will be used to evaluate various conventional Jurassic-aged formations. Horse Hill Developments Ltd is operator of the well, in which Magellan has a 35% direct carried interest.

Magellan has decided to defer the opportunity at Horse Hill-1 to run a suite of unconventional logs over the Kimmeridge Clay and Liassic formations. 

J. Thomas Wilson, President and CEO of Magellan, stated, "We are very pleased with progress to date at Horse Hill, and Horse Hill Developments has proven to be an able operator. The Weald Basin has yielded conventional oil and gas production for decades, and I expect Horse Hill Developments will be a strong partner to Magellan in unlocking value from the conventional prospects at Horse Hill and elsewhere in the Weald. Their efforts will complement nicely our own pursuit of the attractive unconventional development opportunities in the Weald."
