Chesapeake Accelerates Growing Fleet’s Conversion to CNG

July 18, 2011

OKLAHOMA CITY, OK – Chesapeake Energy Corp. announced that it is accelerating its plans to convert the 4,500 vehicles that make up its light-duty fleet, and the 400 heavy-duty vehicles in its fleet, to run on natural gas. In addition, the company’s fleet is growing as it expands its operations. The company said this conversion process would result in savings of $15 - $20 million per year. The company is also converting 100 of its drilling rigs to run on natural gas.

Automotive Fleet spoke with Norman Herrera, director of market development for Chesapeake, about the conversion of the fleet to run on natural gas and its plan for this process over the next few years.

In terms of the company’s projected savings of $15-$20 million, Herrera explained the company’s formula. 

“Each vehicle is driving 30,000 miles per year,” Herrera said. “We own each vehicle for three years. Our fuel economy is, say, 10 mpg, and we’re saving $1.50 per gallon on fuel. So if you put all of those variables together, you get those savings. We’re driving 4,500 vehicles every day in remote areas.”

This conversion makes sense for the company, beyond its goal to increase demand for natural gas as a fuel source, as its fleet is growing rapidly.

“We’ve experienced 16 percent year-over-year growth in our fleet,” Herrera, said. “At this time last year we were in the high 3,000s last year, now we’re at 4,500, and we really expect to be closer to 5,000 next year.”

Herrera said most companies in the natural gas industry are driving either 1/2-ton or 3/4-ton trucks, such as a Ford F-250 or a Chevrolet 2500. In Chesapeake’s case, the company primarily uses the Chevrolet 2500.

“We’re in a CAP (Competitive Assistance Program) with General Motors, so we get a pretty significant fleet discount,” Herrera said. “The truck is a Chevrolet 2500 6.0L extended cab with 21 gallons of CNG fuel storage on board, plus the original gasoline tank. These vehicles are bi-fuel. Our vehicles’ kits are aftermarket, and we’re working closely with IMPCO Automotive.”

Converting the Fleet

Progress in the conversion process has been fast so far, with the company reaching a milestone of having converted its 850th vehicle earlier this year, and is now coming close to its 1,000th vehicle.

“The first place [we’re converting our fleet] is in Oklahoma,” Herrera said. “We announced our 850th vehicle conversion earlier this year. If you took a snapshot on July 13, we’re nearing 1,000 vehicles out of the 4,500. That is every fleet vehicle we operate in the state of Oklahoma.”

Herrera explained that Chesapeake is converting its vehicles on a regional basis. In phase two of the conversion process, he said the next Chesapeake regional fleet to undergo conversion is in northwest Louisiana, in the Haynesville play (a geographic region with a shale formation).

“When we complete the second phase, we’ll be pretty close to the 2,000 number,” Herrera said. “From there, we’re going to the Barnett Shale in Fort Worth. The next two phases are pretty fluid, almost sequential by years, at 1,000 vehicles per year. The third phase will be in Pennsylvania, West Virginia, and Ohio. And the final phase will be the Rockies’ fleet, and that includes Wyoming, Colorado, Montana, and then south Texas.”

In the Oklahoma area, Herrera said the company has a close working relationship with Carter Chevrolet, which has been Chesapeake’s vehicle conversion partner since the company started adding bi-fuel CNG systems to its trucks.

“They do GSA accounts, a lot of other large fleets, but they are our preferred partner to do our vehicle conversions,” Herrera said.

The company said it’s converting vehicles as quickly as it can but that without a factory solution that it can use in the remote areas the company operates in, it’s limited by the speed at which it can convert its vehicles.

“We’d say that if the OEMs come out with a factory solution, then we would listen to them loud and clear,” Herrera said. “If it has that warranty and service relationship, we would look to that direction, too, if that was the direction from Detroit.”

The Big Picture

The natural gas company made this announcement in the context of its plan to invest $1 billion over the next 10 years in an effort to change the transportation fuels market in the U.S. to grow demand for natural gas in that market. Chesapeake said it’s directing approximately 1 – 2% of its forecasted annual drilling budget to projects that the company said will stimulate demand for this fuel.

The company’s investments focus on increasing the existing domestic onshore oil and natural gas liquids production by 3-4 million barrels per day by accelerating drilling and hydraulic fracturing, investing in the construction of publicly available CNG and LNG fueling stations, and deploying processes that can convert natural gas into a room-temperature, tank-ready transportation fuel.
