Energy stocks fell back from recent gains Tuesday as oil prices cooled off, while oil service firm Cameron International drew praise from analysts on plans to buy Natco Group for $780 million in stock.

The Amex Oil Index (XOI) dropped 0.6% to 1,014. The gauge of major petroleum producers and refiners had jumped 9% to 1,020 in three straight days of powerful gains on May 28, 29 and June 1.

The Amex Natural Gas Index (XNG) dropped 1.3% to 455.

The Philadelphia Oil Service Index (OSX) subtracted 1% to 183.

Crude futures fell 81 cents to $67.77.

Cameron International Corp. (CAM) said it would buy Natco Group (NTG) for 1.185 shares of stock for each share of Natco. The price valued the smaller firm at a 24% premium to its Monday close. Shares of Natco rose 15% to $35.53 a share. Cameron dropped 4.3% to $31.05.

Analysts at Pritchard Capital Partners said Cameron will benefit from Natco Group's research and development in the emerging area of sub-sea processing of raw petroleum products to remove water and other matter.

"Cameron is acquiring NTG's strategically positioned manufacturing facilities/distribution network in Southeast Asia, the Middle East, South America and West Africa plus manufacturing capabilities in processing and separation products," Pritchard analysts said in a note to clients.

"This is a major positive for Cameron as it trailed FMC Technologies, Inc.'s (FTI) market leading subsea processing solutions technologies," Pritchard said.

Royal Dutch Shell Plc (RDSA) Chief Executive Jeroen van der Veer said Tuesday he's seen costs come down in recent months after re-working contracts with its oil service firms.

"As far as projects are concerned and normal operating costs, we see a lot of our renegotiations ... enter with lower costs at this moment," he said at an industry conference in Abu Dhabi, according to a Reuters report.

Among analyst actions, Citigroup downgraded French integrated oil giant Total SA (TOT) to hold from buy. Total SA shares fell 1.3% to $58.71.

Atlas Pipeline Partners (APL) said it's closed a joint venture with Williams (WMB) called Laurel Mountain Midstream LLC, which plans to develop Atlas' presence in the southwestern Pennsylvania portion of the Marcellus Shale. Shares of Atlas Pipeline Partners fell 1.3% to $5.34.

Atlas Energy Resources, LLC (ATN) will become the anchor tenant on the system. As part of the deal, Williams will pay approximately $90 million in cash to Atlas, which will hold a 49% equity interest in Laurel Mountain.
