Elimination of Engine Aftertreatment Key to Cutting Costs


Time is money, uptime is king and engine reliability is non-negotiable. In an environment of growing complexity, the oil and gas industry is looking for ways to drive escalating service and supply costs down. Balancing the scale between engine performance and efficiency can be a tightrope walk, but with the recent leaps in advanced engine technology, the industry has welcomed new cost-cutting innovations, with new system-streamlining technologies on the horizon. Once in market, operators can expect to see maintenance and fuel costs controlled even before a new engine is installed.

Methane Regulation: It’s Not Just for Cows


When the Obama Administration released its methane emission reduction plan in March, the late night shows trotted out tried and true flatulent cow jokes. And national media ran a picture of a serious-looking farmer plugging something into a sad-looking cow carrying a “methane backpack.”

Did EPA’s New Carbon Emissions Rules Put Coal Industry on Life Support?


It’s not dead yet, but the Environmental Protection Agency’s (EPA) new limits on carbon emissions has all the appearances of putting the U.S. coal industry into a medically-induced coma with the slimmest hope of recovery coming in the uncertain form of carbon capture and sequestration (CCS) technology.
 
Appearances Can Be Deceiving
 
The EPA’s new carbon emissions rules apply only to new power plants. That means that it’s unlikely we’ll be seeing many, if any, new coal-fired power plants in the works. But that was already the case, even before the EPA’s new limits, because lower prices on cleaner-burning natural gas have made natural gas-powered plants a more attractive option.
 
Coal consumption had already fallen by about 5 percent last year, according to the Energy Information Administration (EIA), due to low gas prices driving U.S. utilities away from coal. With natural gas plants emitting about half the carbon dioxide as coal plants and the precedent of these new EPA limitations, don’t expect to see those plants returning to coal any time soon.

Six Steps to 49 CFR Part 192 Compliance while Achieving Long-Term Business Value


Over the last two decades, the Department of Transportation (DOT) and the Pipeline and Hazardous Materials Safety Administration (PHMSA) have been challenged with how to define and regulate the United States’ over 230,000 miles of onshore gathering gas lines or GGLs.  Historically, GGLs have been small in diameter, operate at pressures ranging from 400 to 600 pounds per square inch (psi), connect individual wells or production fields (covering at most a few hundred miles), and located, for the most part, in very rural areas. With the increase of natural gas production from shale exploration over the last six to 10 years, that is no longer the case.
 
In 2006, PHMSA introduced new language into DOT’s 49 CFR Part 192, and defined new requirements for “regulated onshore GGLs” and “unregulated onshore GGLs.”  However, due to the growth in shale gas production since then, PHMSA has stated its growing concern for human health and the environment. This concern is due, in part, to the increase in GGL diameters to 12” to 36” with maximum allowable operating pressures (MAOPs) as high as 1480 psi.  PHMSA are also concerned that it is increasingly common for GGLs to run through urban centers – with potentially hazardous consequences.
