Oil and gas services-related exchange traded funds were leading the energy sector rally Tuesday, with Transocean (NYSE: RIG) shares surging, as a weak dollar and a Kuwait strike prop up crude oil prices.

On Tuesday, the SPDR Oil & Gas Equipment & Services ETF (NYSEArca: XES) advanced 4.4%, Market Vectors Oil Service ETF (NYSEArca: OIH) gained 3.7% and PowerShares Dyanmic Oil and Gas Service ETF (NYSEArca: PXJ) rose 3.6%. The three oil & gas equipment & services related ETFs also broke above the resistance at their respective 200-day simple moving averages.

The oil services sector was rallying, with RIG jumping 10.1%. Transocean shares were strengthening on positive earnings revisions for the quarter and year.

Additionally, Diamond Offshore Drilling (NYSE: DO) also jumped 5.7% on Tuesday.

XES includes a 3.7% tilt toward DO and 3.2% in RIG. OIH holds 3.2% RIG and 2.0% DO. PXJ includes 2.6% RIG and 2.6% DO.

Meanwhile, the broader Energy Select Sector SPDR (NYSEArca: XLE) was up 1.6% Tuesday. XLE has a 16.8% weight in the energy equipment & services sub-sector.

The oil equipment and services industry is also beginning to outperform the broader energy sector. Over the past three months, XES was up 24.7%, OIH increased 23.0% and PXJ returned 24.7% while XLE was 19.7% higher.

The energy sector was among the better performing areas of the market Tuesday as a depreciating U.S. dollar and the ongoing Kuwait oil worker strike supported oil prices.

The United States Oil Fund (NYSEArca: USO), which tracks West Texas Intermediate crude oil futures, increased 2.1% and the United States Brent Oil Fund (NYSEArca: BNO), which tracks Brent crude oil futures, rose 2.0% on Tuesday as WTI futures added 2.9% to $41.0 per barrel and Brent futures were up 2.3% to $43.9 per barrel.

The U.S. Dollar Index, which tracks the movement of the USD against a group of developed market currencies, dipped 0.5% to 94.0 Tuesday, a 10-month low – a weaker greenback makes USD-denominated commodities like oil cheaper for foreign buyers.

The labor stop in Kuwait cut daily output by as much as 1.7 million barrels and entered its third day, reports Mark Shenk for Bloomberg.

“Having a strike in one of the the most stable, better-run producers comes as a big surprise,” Francisco Blanch, head of commodities at Bank of America Merrill Lynch, told Bloomberg. “The market viewed the sell off as a buying opportunity. The market is moving from a surplus to a deficit in the second half of the year.”
