UPDATE 1-Exxon still scouting for shale oil and gas assets

HOUSTON Jan 12 (Reuters) - Exxon Mobil Corp (XOM.N) said on Wednesday that it will continue to look for unconventional assets to buy as it seeks to grow that part of its business following last year's acquistion of XTO Energy.

"We will continue to evaluate acquisitions," Mark Albers, senior vice president for Exxon, told the Goldman Sachs Global Energy Conference.

Since its purcase of XTO, Exxon has added more unconventional acreage -- or acreage where technology like hydraulic fracturing is required to extract oil and gas -- to its portfolio.

Last month, Exxon paid $650 million to buy natural gas assets in the Fayetteville shale in Arkansas from Petrohawk Energy Corp. (HK.N)

Shares of Exxon were up 69 cents, or nearly 1 percent, at $76.38 in afternoon trading on the New York Stock Exchange. (Reporting by Anna Driver in Houston, editing by Matthew Lewis)
