Denver-based Enservco Corp., a provider of well-site services, said it will invest $6 million in capital expenditures during 2013, with $4.7 million being allocated to new equipment fabrication. The budget also includes $1.3 million for enhancements to existing equipment. Management estimates the annualized revenue potential from the new equipment at about $10 million. The equipment includes nine frack heating trucks with a total of 12 burner boxes, four hot oilers and two well acidizing trucks. The investments will expand the company’s frack heating capacity by 40% and increase its hot oiling fleet by 15%. Enservco said sales during April reached $3.7 million, up 85% from one year ago. The improvement was fueled in part by cool spring temperatures across the company’s service territories, as well as sustained demand for fluid heating services, particularly in regions where new fracking techniques require higher water temperatures than traditional frack designs.

In the rush to get more gathering and processing infrastructure in place to handle currently flared Bakken Shale associated gas, some hurdles are being met by wells with heavy concentrations of sour gas, or high hydrogen sulfide (H2S) levels, according to North Dakota energy officials.

The Federal Energy Regulatory Commission has vacated authorizations for Calhoun LNG and Point Comfort Pipeline to site, construct and operate a liquefied natural gas (LNG) import terminal and associated facilities at the port of Port Lavaca-Point Comfort in Calhoun County, TX. The Commission approved the project in September 2007 (see Daily GPI, Sept. 21, 2007). The companies, which had planned to build a 1 Bcf/d LNG terminal and a 27.1-mile, 36-inch diameter pipeline from the terminal to pipeline interconnects southwest of Edna, TX, filed a request to vacate the authorizations in December. Calhoun LNG is a subsidiary of Houston-based Gulf Coast LNG Partners LP.

In a long-term bet on abundant U.S. natural gas, South Africa’s Sasol Ltd. on Monday announced plans to construct a $16-21 billion natural gas-to-liquids (GTL) plant in Westlake, LA — the second largest commercial plant of its kind in the world.

Dominion Resources Inc. has secured a long-term natural gas gathering service agreement in northeastern Ohio with M3 Ohio Gathering (Momentum) to process wet gas from the Utica Shale and is readying several projects in the Utica and Marcellus shale region to expand capacity services, CEO Tom Farrell said Thursday.

CHS Inc., the nation’s largest farmer-owned cooperative, launched a proposal Wednesday to build a $1.1-1.4 billion nitrogen fertilizer manufacturing plant in North Dakota that would take advantage of natural gas feedstock to provide U.S. and Canadian farmers with enhanced supplies of crop nutrients.

Enterprise Products Partners LP plans to build one of the world’s largest propane dehydrogenation (PDH) units on the Texas Gulf Coast to take advantage of abundant supplies of propane thrown off by shale gas plays and to address periodic shortages of propylene in the region.

Technology spawned from shale gas got special notice this month in Pennsylvania, with two innovations taking top honors in a competition geared to maximize the economic return from the Marcellus and Utica shales.

Chevron Phillips Chemical Co. (CPChem) LP announced Monday that it has selected a site near Old Ocean, TX, in Brazoria County, for two polyethylene facilities, part of the company’s U.S. Gulf Coast Petrochemicals Project.
