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.

What if I told you that the government was blocking America’s prosperity in the form of enormous untapped energy reserves that represent wealth and jobs that would once again put America on the path to fiscal security and growth?
Recently, Matt Vespa, on CNS.com reported that the International Energy Agency released a report that said the United States has the capacity to outpace Saudi Arabia as one of the world’s leading producers of oil. It projected that the U.S. could become a net oil exporter around 2020. It could become entirely self-sufficient.
Even so, the Obama administration just moved to cordon off 1.6 million acres estimated to represent one trillion barrels worth of oil in the name of conservation. At the same time, the Environmental Protection Agency is moving to so encumber hydraulic fracturing—fracking—with so many regulations it will thwart increased use of this extraction technology that has been safely in use for decades.
As Dan Kish, Senior Vice President for Policy at the Institute for Energy Research, warns, there is a major government effort “to federalize hydraulic fracturing regulation” which is already being done by states “in a very professional and knowledgeable way. Take fracking away, the oil and gas production drops.”
For years, through many administrations, the federal government has been doing everything in its power to restrict drilling domestically and off-shore where billions of barrels of oil remains untapped. In October, a Wall Street Journal editorial noted that “The latest example is the Interior Department’s little-noticed August decision to close off from drilling nearly half of the 23.5 million acre National Petroleum Reserve in Alaska.”
As far back as 1976, Congress designated the Reserve a strategic oil and gas stockpile to meet the “energy needs of the nation”, but oil and gas that is not extracted meets no needs. It keeps the nation dependent on imported oil and gas. In an August 22 letter to Interior Secretary Ken Salazar from the entire Alaska delegation in Congress called it “the largest wholesale land withdrawal and blocking of access to an energy resource by the federal government in decades.”
Noting that “Most of the other 11.5 million acres are almost indistinguishable from the acreage owned by the state that is being drilled safely nearby” the Journal pointed out that drilling on privately owned land has seen North Dakota pass Alaska as the second highest oil-producing state behind Texas.”
According to the Congressional Research Service, “The federal government owns roughly 635-640 million acres of the land in the United States. Four agencies administer 609 million acres of this land; the Forest Service in the Department of Agriculture, and the National Park Service, Bureau of Land Management, and Fish and Wildlife Service, all in the Department of the Interior.” The Bureau of Land Management manages 248 million acres and is responsible for 700 million acres of subsurface mineral resources.
Mostly by stealth, more and more privately owned land is being purchased by the federal government. In September 2011, Audrey Hudson, writing for Human Events, reported that “The Obama administration is spending $35 million to buy 30,000 acres of private property across the U.S. this year to make permanent homes for mice, fairy shrimp, mussels, prairie bushes and beetles. Those are just some of the 70 critters and plants to benefit from the land purchases in a dozen states as part of the government’s habitat conservation plans for endangered species.”
Quoting Rob Gordon of The Heritage Foundation, Hudson reported that “The federal government already owns more land than Germany, France, the United Kingdom, Spain, Italy, and Poland combined.” The Endangered Species Act is just an excuse to secure ownership of more land and, in particular, to restrict development of every description from housing to hospitals.
Instead of a future in which our oil and gas reserves could unleash all manner of economic growth and the generation of thousands of new jobs, Ben Wolfgang, reporting in the November 22 edition of The Washington Times, “The drilling process that has brought the U.S. energy independence within reach faces renewed scrutiny from the Obama administration and an uncertain future in many states.”
“Next month, the Environmental Protection Agency is expected to release a draft of its long-awaited report on suspected links between water pollution and fracking, which uses huge amounts of water, combined with sand and chemical mixtures, to crack underground rock and release trapped oil and gas.” Fracking, however, occurs well below underground water levels and has been shown to have no effect on it.
What we are witnessing is the deliberate effort by the Obama administration, in concert with earlier administrations, to deny the economic benefit of tapping the nation’s vast reserves of oil and gas domestically and off-shore. This was evident, as well, in the President’s decision about the XL Keystone pipeline on the grounds that it threatened aquifers if allowed to proceed. Thousands of jobs were lost in that single decision with no evidence of the truth of the assertion.
As the nation sinks further into economic decline and default, it is obvious that the nation’s energy sector is being thwarted at a time when it holds the promise of lifting it out of growing unemployment, higher energy costs, and the drumbeat of utterly false environmental claims about greenhouse gas emissions.

Cummins Westport announced it has begun development on the ISB6.7 G, a mid-range 6.7 liter natural gas engine designed to meet the increasing demand for on-highway vehicles powered by lower cost, cleaner and increasingly abundant natural gas. As a leading supplier of natural gas engines, Cummins Westport Inc. continues to expand its product range to supply the growing demand for natural gas engines.
The ISB6.7 G engine will be based on the Cummins ISB6.7 diesel engine and will use Cummins Westport’s proven spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology. Exhaust aftertreatment will be provided by a simple, maintenance-free three-way catalyst.
The engine will run on compressed natural gas (CNG), however, the natural gas may be stored on the vehicle in liquefied natural gas (LNG) state or as CNG. The ISB6.7 G is expected to be in production by 2015 and will be designed to meet Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regulations in force at the time of launch.
“The addition of the ISB6.7 G will round out our family of high performance natural gas engines,” said Jim Arthurs, President of Cummins Westport. “It joins the 8.9-liter ISL G, with over 16,000 engines in service, and the 11.9-litre ISX12 G, which will start production in 2013, to give our customers a broad range of natural gas engines for on-highway applications.”
