First LNG-Fueled Hydraulic Fracturing Completed in Eagle Ford Play

The liquefied natural gas (LNG) division of Calgary-based Ferus LP successfully completed in October what the company believes to be the first-ever hydraulic fracturing operation utilizing liquefied natural gas (LNG) as engine fuel in North America.

Ferus’ LNG Division was engaged by a major oil and gas service company in the United States to conduct the pilot project, which involved six dual-fuel 2,250 horsepower pressure pumper units, powered by LNG, to stimulate well performance in the south Texas Eagle Ford shale.

The dual fuel systems allow for natural gas and diesel to be consumed simultaneously with no decrease in performance, Jed Tallman, manager of market development for Ferus LNG, told Rigzone. Approximately 10,000 gallons of LNG was used in the pilot project, which took place in the southwestern portion of the Eagle Ford play.

While the company cannot discuss the plans of the operator involved in the pilot project, Ferus LNG has been contacted by numerous operators and service companies regarding LNG as a low-cost, environmentally superior alternative fuel, Tallman said.
The increase in interest by operators and service companies in using LNG for hydraulic fracturing has been dramatic.

“Because of the large amounts of diesel consumed in fracturing fleets, the use of LNG as an alternative fuel will result in cost savings for the operator or service company, not to mention a significant reduction in greenhouse gas emissions,” Tallman commented.

“LNG offers significant environmental and cost-saving advantages and is quickly becoming the alternative fuel of choice for heavy-duty high horsepower on-road and off-road applications in North America,” said Ferus President and CEO Dick Brown in a Nov. 28 statement. “We were very pleased to play such a critical role in this ground-breaking project, and we intend to be at the forefront of this growing industry as more and more diesel consumers make the switch to North America’s abundant supply of natural gas.”

It is difficult to estimate the specific size of the market for LNG in hydraulic fracturing and in other areas such as railroad transportation and trucking moving forward, Tallman commented.

“But given the economic benefits, improved emissions profile, and increased gas production, we feel that LNG will make up a considerably larger percentage of our domestic energy consumption in the future.”

While the use of LNG for hydraulic fracturing is not being specifically done to alleviate criticism of hydraulic fracturing, the improved emissions profile of natural gas certainly is a benefit, Tallman said.

To complete this project, which marks a significant milestone in the adoption of natural gas as an alternative engine fuel, Ferus managed the entire supply chain on behalf of its client including LNG supply, transportation, and on-site storage and vaporization using specialized equipment and highly-trained personnel.

In addition to being a cleaner-burning and less expensive fuel alternative, LNG is non-toxic, non-combustible, non-flammable as a liquid, and dissipates into the atmosphere in the event of a leak or a spill, making it safer than diesel and gasoline, the company said in a statement.

The use of LNG requires specialized fuel handling equipment and additional training for individuals involved in the LNG supply chain.

“As a leading provider of cryogenic liquids for the energy sector, Ferus is uniquely qualified for the undertaking,” Tallman said.

The increased use of natural gas to fuel not only hydraulic fracturing but transportation has grown thanks to the abundance of shale gas in the United States.

The use of natural gas over diesel is becoming more widespread, likely due to the cost benefits associated with fuel switching, according to a Nov. 28 analyst report from GHS Research. GHS referenced Baker Hughes‘ Nov. 26 announcement that it would convert a fleet of its Rhino hydraulic fracturing units to bifuel pumps as a way to improve operational efficiency, lower costs and reduce health, safety and environment impacts. Bifuel is a mix of gas and diesel.

The new pumps use a mixture of gas and diesel, reducing diesel use by up to 65 percent with no loss of hydraulic horsepower. The converted fleet, which meets all U.S. Environmental Protection Agency emissions standards, can also reduce a number of emissions including nitrogen oxides, carbon dioxide and particulate matter.

Baker Hughes first converted a small fleet of its units in Canada; the success Baker Hughes saw with this endeavor prompted to company to convert an entire fleet in the United States. The company is converting several more fleets of Rhino trucks to Rhino Bifuel equipment. Baker Hughes also has a test program in Oklahoma, where a number of light-duty vehicles have been converted to natural gas.

Westport Innovations, which manufactures natural gas-powered truck engines, recently reported it is building a railroad locomotive engine that can run on LNG. During 2012, the company saw “broad consensus” for the first time that natural gas will take material market share in every global transportation market within the next five years, said David Demers, chief executive officer for Westport, during the company’s third quarter 2012 earnings update Nov. 8.

Demers noted that consensus suggests that the company will see 7 percent to 15 percent of the North American trucking industry run on natural gas in 2017.

Westport Innovations will also introduce new natural gas-powered versions of the Ford F-450 and F-550 Super Duty trucks in mid-2013, the company said in a Dec. 3 statement.

“Although current demand for natural gas used in vehicles is minor relative to the demand associated with power generation, industry and residential heating, it is catching on and may soon reach a tipping a point where growth rapidly accelerates, with or without government intervention,” GHS reported.

AmericaCNG to Build LNG Processing Plants

AmericaCNG has arranged funding for plans to build three strategically located LNG processing plants in Texas, Oklahoma and New Mexico targeting the wholesale and resale markets.

Plans call for development to begin in 2013. Each plant will produce between 7,500 to 40,000 Diesel Gallons Equivalent (DGE) per day of capacity, subject to current and future contractual commitments. According to Joseph Farley, Director of Business Development, “We see a need for LNG and CNG as another important supply fuel to the Oil & Gas industry and service providers. Producers and Suppliers of Oil & Gas are looking for ways to cut their fuel cost and by switching to Natural Gas for their rigs, frac units and fleets they can save millions of dollars each year.

“AmericaCNG.Com,Inc along with their Strategic Alliance Partners(SAP) can convert the trucks, the frac units and the drilling rigs to run off CNG. Thigpen Energy, one of our SAP, is a field service company that specializes in the installation and operation of natural gas fueling infrastructure, be it CNG, LNG or field gas.

“Gas safety equipment, crew safety training and fuel reconciliation are all part of the Thigpen Energy solution. By utilizing our LNG processing, storage and transportation capabilities we will be able to wholesale the fuel, plus transport the fuel to each well site, regasify it back to CNG, and sell it to drillers, suppliers, service companies and converted vehicles…”

“We have the capability to turn around a project in about 180 days for the smaller units out in the field.”

Another SAP is Alternative Gas Processing Inc.. They supply wellhead gas processing equipment for methane and NGL’s, portable LNG fuel skids, and LNG and CNG transportation modules. Methane and NGL recovery at the well head can be accomplished with no out of pocket expense to the producer in specific targeted areas.
