Item 7.01 – Regulation FD Disclosure

The information in this Item 7.01 of this Current Report, according to general instruction B.2., shall be deemed to be “filed” (not furnished) for the purposes of Section 18 of the Securities Exchange Act of 1934.

On August 15, 2012, the Company held a conference call to discuss its financial results for the second quarter of 2012. In addition to information previously provided, management provided certain details regarding its operations and expectations for the future, some of which are summarized below.

Management explained that the Company faced an increase in competition in its fluid logistics segment in the second quarter of 2012, as equipment from dry gas markets was transferred into the oil and liquids rich markets where the Company primarily operates and new start-up companies began entering the fluid logistics market. During the call, management discussed how this competition has created labor pressure, as some skilled employees have been hired away by competitors. While management feels that this competitive pressure will continue through 2012, it feels that the Company’s existing geographic footprint and modern equipment and steps it has taken in response to the increased competition will help its financial performance for the remainder of 2012.

In response to questions during the conference call, management provided information regarding its plans and expectations for the future. Management estimated that its total capital expenditures for the full year 2012 will be approximately $110 million to $115 million. Management also stated that it expects capital expenditures for 2013 to be more limited, with the Company adopting a more conservative approach to expansion during that year. Further, management discussed the Company’s recently acquired coiled tubing unit. Management estimates that this unit, as well as the other similar units on order, will be able to achieve attractive margins and revenue per unit, dependent on market conditions and other factors that may impact utilization.

Additionally, management was asked during the call about the possibility of the Company repurchasing equity or senior notes. Management stated that it continually evaluates opportunities to increase shareholder value, including assessments of the appropriateness of repurchasing equity or senior notes.

This report contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. The accuracy of the Company’s assumptions, expectations, beliefs and projections depend on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this press release for a variety of reasons, which include: supply and demand for oilfield services and the level of oil and natural gas prices; the continued uncertainty in the global financial markets and its effect on domestic spending in the oil and natural gas industry; the Company’s ability to maintain or improve pricing on its core services; the potential for excess capacity in the industry; competition; future decisions regarding capital expenditures; and levels of success in achieving utilization and revenues with new coiled tubing units. Additional factors that you should consider are set forth in detail in the Risk Factors section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2011, as well as other filings

the Company has made with the Securities and Exchange Commission. Should one or more of the foregoing risks or uncertainties materialize, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and the Company’s business, financial condition and results of operations could be materially and adversely affected.
