Excitement continues to build over America’s possible energy independence, courtesy of shale energy production. Innumerable articles describe exploration and production companies, pipeline companies, and refiners. But a lesser-known category of stocks also stands to benefit from America’s booming energy production: the “pick-and-shovel” companies providing the hardware and equipment that energy producers need.

Diesel where the trucks are
Think about this.  Crude oil is extracted from Bakken shale in the Dakotas, shipped to a coastal refinery, made into diesel fuel … and returned to the Dakotas to fuel all the trucks there. Why not make diesel fuel right where it’s extracted?

That’s what MDU Resources Group Inc (NYSE:MDU) thought, so it teamed up with Calumet Specialty Products Partners to build a refinery in North Dakota. The state recently issued final approval to build the refinery, and construction should begin this month. According to the company, diesel fuel consumption in North Dakota grew 75% over the past four years, with no letup in sight.

This joint venture adds to MDU Resources Group Inc (NYSE:MDU)’s portfolio of businesses. Currently, the company operates a variety of endeavors, including regulated electricity generation, unregulated  energy ventures, and construction. Oil and gas production is the single biggest source of revenue, and will likely drive future revenues higher.

As a major electric utility in the Dakotas, MDU Resources Group Inc (NYSE:MDU) stands to profit from the growing population coming to work in the energy business. MDU Resources Group Inc (NYSE:MDU)’s pipeline business could also benefit from growing oil and gas production. Lastly, MDU’s construction division should thrive amid continued transportation building activity.

Keep an eye on the 40% debt the company carries.  Much of that is capex to seize  business opportunities. MDU Resources Group Inc (NYSE:MDU)’s smart to invest in the future, but you should monitor the company to insure that its investments pay off.

Water, water, everywhere — but you don’t want to drink it.
Hydraulic fracturing revolutionized shale energy production, but the process leaves behind a lot of contaminated water. Enter Heckmann Corporation (NYSE:HEK).

Heckmann (soon to be Nuverra Environmental Solutions) recycles or disposes of water after fracking.  It also collects and recycles oil-related waste products, antifreeze, and solid waste products from shale exploration sites.  In short, Heckmann provides clients with a single vendor to clean up hydraulic fracturing waste.

Recently, Heckmann Corporation (NYSE:HEK) completed a merger with the private firm Power Fuels, the largest environmental services company in the Bakken shale area.  Power Fuels grew about tenfold since 2007, and it should complement Heckmann Corporation (NYSE:HEK) nicely.

Currently, Heckmann Corporation (NYSE:HEK) stock has been under pressure from declining natural gas prices and a large short position. But given the Power Fuels acquisition, I’m not sure selling short makes sense. Motley Fool analyst Matt DiLallo believes that the market thinks Heckmann’s business depends on shale gas exploration, whereas the company actually derives 70% of its income from liquids and oil plays.

Heckmann Corporation (NYSE:HEK) looks like an investment for those willing to wait for acquisition expenses to run their course. Once they do, this stock could pleasantly surprise the market.
