LONDON (Dow Jones)--BP PLC (BP) is expected to announce Tuesday an expansion of its U.S. shale-gas operations through a joint-venture deal in Texas with privately held Lewis Energy Group worth at least $160 million, people familiar with the situation said.

BP's move is the latest in a string of deals that have brought major oil companies into U.S. shale gas--a substantial resource that has boosted U.S. gas reserves significantly and is transforming the energy industry. While relatively small compared with the multibillion-dollar deals struck recently, BP's move underscores the growing interest of the biggest integrated energy companies, which were slow to recognize the potential of shale gas. BP, Norway's Statoil SA (STO) and other big oil companies also aim to apply expertise gained in North America to their efforts overseas to extract gas from deep, hard, shale-rock formations.

Several companies have been jostling for acquisitions in the sector, which was pioneered by smaller, independent U.S. producers such as Chesapeake Energy Corp. (CHK) and XTO Energy Inc. (XTO). France's Total SA (TOT) agreed in January to acquire a quarter of Chesapeake's Barnett Shale operations in Texas for $2.25 billion. This came the month after Exxon Mobil Corp. (XOM) gave shale-gas development a definitive stamp of approval by agreeing to acquire XTO in an all-share deal valued at around $31 billion.

BP will take a 50% stake in 80,000 acres of the Eagle Ford Shale play in the southeastern part of Texas held by Lewis Energy at a price of $4,000 to $4,500 an acre, one of the people familiar with the matter said.

The two companies are already running one drilling rig on the license and could be running four rigs by the end of the year, another person said.

A BP spokesman in Houston declined to comment. Lewis Energy didn't respond to requests for comment.

The Eagle Ford Shale is a rapidly developing oil and gas field, which is drawing significant interest from energy companies. U.S. oil major ConocoPhillips (COP) holds acreage in the Eagle Ford, and companies including Chesapeake and Petrohawk Energy Corp. (HK) are looking to expand their positions there.
