There's a lot to be said for better mousetraps in any industry, but service companies that can help energy producers reliably increase their well productivity are almost always popular. With its patented and proven surfactant, Flotek (NYSE:FTK) has battled back from near bankruptcy with strong growth. Given that management has big expectations for its fluids business, the growth story may yet have room to run.

A Diverse Set of Services 
Flotek offers a relatively diverse array of services across chemicals, drilling equipment and artificial lift, but the chemicals business is more than half of sales and gross profits. We'll get back to the chemicals business in a moment, but the company's tools and drilling equipment (which are sold under brand names like Teledrift and Cavo) appear on as many as one-quarter of the rigs in North America. While the artificial lift business has historically been weighted toward gas production, some of the technologies and products can be used in oil production.
