By John J. Interval It is hard for a petroleum geologist like me to find good news in the drastic cuts in shale-gas drilling or the calls by some politicians for a moratorium on fracking, but there is at least one silver lining: Producers in the Marcellus have become much more efficient, using innovative technologies and better knowledge of the shale formation to complete a well in less than half the time it took a decade ago. Producers are...

Chevron Corp., which entered the Pennsylvania shale-gas competition this year with the acquisition of Atlas Energy Inc., on Wednesday substantially beefed up its stake by acquiring new acreage in southwestern Pennsylvania. The San Ramon, Calif., company will acquire leases covering 228,000 acres from closely held Chief Oil & Gas L.L.C. and Tug Hill Inc. The terms weren't disclosed. In February, Chevron paid $3.58 billion for Atlas and its 622,000 Marcellus acres. Atlas was founded by Philadelphia's Cohen family.

A natural gas subcommittee appointed by U.S. Energy Secretary Steven Chu is recommending more public disclosure, more tracking of data, and other actions to reduce the environmental and safety risks of shale gas production in the nation. In a report to be released Thursday, the committee calls for better ways to measure and limit air pollution, and recommends water-quality requirements. It also wants to see the full disclosure of chemicals in fluids used for fracking, the process in which water and additives are injected underground at high pressure to break apart the geologic formation and release the gas. Addressing a contentious issue - whether methane contaminating some wells is related to drilling or is from natural causes - it recommends determining background levels of methane in nearby water wells before drilling.

Since the federal government deregulated natural gas prices in the 1980s, the prices of crude oil and natural gas have moved more or less in tandem. But in the last three years, the prices have become unhinged. One reason is the dramatic increase in natural gas production from unconventional formations such as Pennsylvania's Marcellus Shale, which has driven down natural gas prices while crude oil prices have soared. When the two fossil fuels are compared on the basis of energy equivalency, natural gas is a bargain compared with oil. A dollar spent on natural gas buys more than three times the energy that a dollar spent on crude oil buys.

SYCAMORE, Pa. - The towering flares that turn night into day in the Marcellus Shale gaslands are becoming an increasingly rare sight. Natural gas producers are turning to new techniques to capture the gas emitted during the well-completion process. In the past, a well's initial production was typically vented or burned off to allow impurities to clear before the well was tied into a pipeline. Now, more operators are employing reduced-emission completions - a "green completion" - a process in which impurities such as sand, drilling debris, and fluids from hydraulic fracturing are filtered out and the gas is sold, not wasted.

ISSUE | MARCELLUS SHALE TAX Additional expenses will hurt industry, state Energy companies are laying off employees left and right. Pennsylvania won't continue to enjoy the billions of investment dollars it has received from companies developing shale gas in our commonwealth. Reserved Environmental Services employs 70 Pennsylvanians, and 85 percent of our workforce is blue collar. We've postponed capital projects this year and cannot hire an additional 20 employees. And we are not alone.

The Marcellus Shale, which according to some geologists is the world's second-largest natural-gas field, holds the potential to create hundreds of thousands of new jobs for Pennsylvanians - while reducing our dangerous dependence on foreign energy resources. We've known about the Marcellus Shale for years. But advances - specifically, horizontal drilling techniques coupled with a 60-year-old technology called hydraulic fracturing, in which fluid is forced underground - have finally enabled us to reach its enormous stores of clean-burning fuel.

Even though a congressman boasts that his bill signed into law in January will assure steps are taken to safeguard new shale-gas pipelines snaking across Pennsylvania, safety regulators surveyed nationally say they still need convincing. The state regulators' fears, expressed to federal auditors about the public-safety threat from badly built or shoddily maintained pipelines, stand as a continuing concern for residents living amid Pennsylvania's gas boom. At issue is whether thousands of miles of pipeline stretched across rural areas will be subject to safety checks to safeguard against flaws or lax upkeep, given that federal law now exempts these lines from safety rules.

A new national study says Pennsylvania, where Marcellus Shale drilling is expanding dramatically, is expected to lead in job growth attributed to unconventional natural gas development. An industry-sponsored study by IHS Global Insight found that unconventional gas production, including shale gas development, supported more than one million jobs nationwide in 2010 and was projected to grow to nearly 1.5 million jobs by 2015. Unconventional gas production supported nearly 57,000 jobs in Pennsylvania in 2010, 13,600 of those directly, according to the study, which projected that the industry would support 111,000 jobs in the Keystone State by 2015, including 26,000 directly.

Royal Dutch Shell P.L.C. became the latest big international player to buy a stake in the Marcellus Shale when it announced Friday that it will pay $4.7 billion for East Resources Inc., a Pennsylvania company that has morphed into a hefty natural-gas operator. In buying East Resources, headquartered in Warrendale, Pa., Shell will acquire about 1.05 million acres of gas leases, including 650,000 acres of Marcellus Shale rights in Pennsylvania, West Virginia and New York. East Resources, which is based in Allegheny County, is most active in Tioga County, in north-central Pennsylvania, and also owns substantial acreage in Allegheny National Forest.
