Spirit Energy Partners To Acquire Assets of Tana Oil and Gas

Unocal Corporation's Spirit Energy 76 unit announced its Spirit Energy Partners, L.P., affiliate has agreed to acquire substantially all the Gulf of Mexico shelf assets of Tana Oil and Gas Corporation. The Tana acquisition includes interests in 12 proven properties and nine offshore platforms. The purchase price was not disclosed. Tana has an estimated net risked resource potential of more than 18 million barrels of oil equivalent (MMBOE), including more than 10 MMBOE in proved reserves. Estimated average annual production for 2000 is more than 10,000 BOE per day. "The acquisition of the Tana assets will provide the opportunity to enhance Spirit Energy's position in areas where we already possess a strong foothold and enjoy highly profitable operations," said John T. Donohue, president of Spirit Energy 76. "These assets can be integrated immediately into our portfolio." The transaction became effective Oct. 1, 1999. Closing is expected February 3, 2000. A majority of the purchase price will be financed by Spirit Energy Partners, an entity formed by Unocal and The Northwestern Mutual Life Insurance Company to acquire producing properties in existing areas of operation. Unocal's 50-percent interest will be accounted for on an equity basis.
