A new report from the Department of Energy calls for the creation of a shale gas production organization -- a private sector agency that would set safety standards and address environmental concerns
The boom in natural gas extracted from shale rock through new technology holds out great transformative promise for the future: for consumers in lowering energy costs, for workers in creating domestic jobs, for the environment as a substitute for coal, for balance of trade as we may export more than we import and for energy security as we become less dependent on foreign oil and gas and reduce the influence of nations like Iran, Russia and Venezuela.
But today shale gas production faces important environmental and safety issues which must be addressed through both voluntary corporate action and appropriate regulation, with business leaders playing a key role in both spheres.
This is a central conclusion in an important, interim report from a panel of experts constituted by the Department of Energy to assess environmental and safety implications of the new technologies of horizontal drilling and hydraulic fracturing which have made the shale gas boom possible.
The report was issued on August 11th, but it was lost amidst stock market gyrations and global economic uncertainty. Yet, the long-term implications of dramatically increasing supplies of natural gas from shale are of first-order significance to the global economic future. And the report -- from the shale gas subcommittee of the Secretary of Energy Advisory Board -- provides incisive perspective on how to balance economic and environmental issues and on the central part enlightened business leaders must play.
The remarkable story of extracting gas from shale through new technology has become widely known in recent years. Natural gas provides about 25 percent of U.S. total energy. Production of gas from shale formations has gone from virtually zero a few years ago to 30 percent of total U.S. gas production today and is projected to be in the vicinity of 45 percent by the middle of the next decade. (Shale gas recovery -- from an "unconventional deposit" -- is in contrast to gas recovery from "conventional" deposits in porous rocks which need only to be tapped by a well to rise to the surface through existing pressure.) The size of U.S. shale gas reserves continues to grow as exploration occurs around the country -- today they are about 30 percent of all natural gas reserves.
As drilling and "fracking" technologies change, gas supplies increase and debates ensue about the nature, degree, and timing of the benefits of this "revolution," so, too, significant debates have emerged about the environmental impact and safety of shale gas production, especially the impact of high pressure water fracturing of shale on air and water quality.
The shale gas subcommittee charts a course between the predictable extremes of the debate (no regulation v. no fracking). Chaired by John Deutch (MIT professor and former deputy secretary of energy and director of the CIA) and comprised of business people, former regulators, environmentalists, academics, and noted energy consultants, the subcommittee clearly identifies a range of environmental and safety issues that must be addressed to maintain the momentum and credibility of shale gas development. Said the report: "An industry response that hydraulic fracturing has been performed safely for decades rather than engaging in the range of issues concerning the public will not succeed." (Environmental concerns have led to a moratorium on shale gas production in France.)
The subcommittee looked at "all steps in shale gas production, not just hydraulic fracturing." And the essence of the report is the reflected in the following :
As with all energy use, shale gas must be produced in a manner that prevents, minimizes and mitigates environmental damage and the risk of accidents and protects public health and safety. Public concern and debate about the production of shale gas has grown as shale gas output has expanded.
The Subcommittee identifies four major areas of concern: (1) Possible pollution of drinking water from methane and chemicals used in fracturing fluids; (2) Air pollution [e.g. ozone precursors, methane and other pollutants from the production life cycle]; (3) Community disruption during shale gas production; and (4) Cumulative adverse impacts that intensive shale production can have on communities and ecosystems.
There are serious environmental impacts underlying these concerns and these adverse environmental impacts need to be prevented, reduced and, where possible, eliminated as soon as possible. Absent effective control, public opposition will grow, thus putting continued production at risk. Moreover, with anticipated increase in U.S. hydraulically fractured wells, if effective environmental action is not taken today, the potential environmental consequences will grow to a point that the country will be faced with a more serious problem. Effective action requires both strong regulation and a shale gas industry in which all participating companies are committed to continuous improvement.
This interim reports focuses on the importance of industry action in providing information, in setting standards and in developing best practices. Such activities, the report recommends, should be adopted by leading companies and then collected and disseminated by a new "shale gas industry production organization." Such an organization would identify "industry techniques or methods that have proven over time to accomplish given tasks and objectives in a manner that most acceptably balances desired outcomes and avoids undesirable consequences." The broad benefits of efforts by an industry-wide organization, the report maintains, will be to provide better information to regulators, to achieve more efficient operations and to inform the public and create public trust. Indeed, the report optimistically hopes that better economic efficiency -- waste minimization, less water usage, and reduced operating footprint -- will also have environmental benefits.
