The U.S. Bureau of Land Management recently revamped 25-year-old rules for oil and gas drilling on federal and Indian lands to deal with environmental concerns about hydraulic fracturing. Both sides of the environmental debate are on the attack.
With real-time monitors, scientists have linked a swarm of small earthquakes west of Fort Worth, Texas, to nearby natural gas wells and wastewater injection. In 84 days from November 2013 to January 2014, the area around Azle, Texas, shook with 27 magnitude 2 or greater earthquakes, while scientists at Southern Methodist Univ. and the U.S. Geological Survey monitored the shaking.
The depth and efficiency of the U.S. natural gas market would buffer it against potential local policy interventions aimed at limiting access to shale gas resources, according to a new paper by energy economists at Rice Univ.’s Baker Institute for Public Policy.
A technology developed by Stanford Univ. scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and natural gas extraction by providing real-time monitoring of the subsurface while lessening the impact on marine life.
Cars that run on natural gas are touted as efficient and environmentally friendly, but getting enough gas onboard to make them practical is a hurdle. A new study led by researchers at Rice University promises to help.
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Natural gas power plants produce substantial amounts of gases that lead to global warming. Replacing old coal-fired power plants with new natural gas plants could cause climate damage to increase over the next decades, unless their methane leakage rates are very low and the new power plants are very efficient.
Hydrocarbon exploration by definition is the search by geologists or geophysicists for hydrocarbon deposits beneath the Earth’s surface, such as oil (petroleum) and natural gas. In such exploration, the oil and gas industry drills holes into the Earth’s surface to extract the petroleum or natural gas. However, such exploration is expensive, not to mention a high-risk operation.
A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change.
A surprising hot spot of the potent global-warming gas methane hovers over part of the southwestern U.S., according to satellite data. That result hints that the U.S. Environmental Protection Agency and other agencies considerably underestimate leaks of methane, also called natural gas. While methane isn't the most plentiful heat-trapping gas, scientists worry about its increasing amounts and have had difficulties tracking emissions.
Penn State Univ. said Wednesday that General Electric Co. will give the school up to $10 million to create a new center for natural gas industry research. GE said the money will support research projects, equipment, and undergraduate, graduate, and postdoctoral fellowships at The Center for Collaborative Research on Intelligent Natural Gas Supply Systems. the money will be donated over the next five years and earmarked for different uses.
Researchers at the U.S. Dept. of Energy (DOE)’s Argonne National Laboratory announced a new tool for analyzing the economic impacts of building new compressed natural gas fueling stations. Called JOBS NG, the tool is freely available to the public. Mostly made up of methane, compressed natural gas is an alternative fuel for cars and trucks that can offer greenhouse gas benefits over gasoline.
North Carolina State Univ. is part of a project team that is researching and developing new catalyst technology to produce the commercially important chemicals ethylene and propylene from natural gas. The project lead, Bio2Electric, LLC, dba EcoCatalytic Technologies, is collaborating with North Carolina State Univ., among other industry partners, to develop the new catalyst technologies.
Reform of energy subsidies in oil-exporting countries can reduce carbon emissions and add years to oil exports, according to a new paper from Rice Univ.’s Baker Institute for Public Policy. The paper reviews the record of energy-subsidy reforms and argues that big exporters should reduce energy demand by raising prices, and that this can be done without undermining legitimacy of governments that depend on subsidies for political support.
The stakes are incredibly high for the safety and compliance efforts of today’s oil and gas industry. Engineers and crews must be trained for increasingly complex processes and procedures used aboard drilling rigs and production platforms. The consequences of inadequate training during oil production can be disastrous to both operator crews and the environment.
High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study jointly led by Purdue and Cornell universities. The findings could have implications for the evaluation of the environmental impacts from natural gas production.
The Obama administration is driving ahead with a dramatic reduction in sulfur in gasoline and tailpipe emissions, declaring that cleaner air will save thousands of lives per year at little cost to consumers. Public health groups and automakers cheered the new rules.
A new study led by the Joint Institute for Strategic Energy Analysis says that the total impact of switching to natural gas depends heavily on leakage of methane during the natural gas life cycle, and suggests that more can be done to reduce methane emissions and to improve measurement tools which help inform policy choices.
The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, as well as those from the natural gas industry specifically.
Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane coming from? Research by a California Institute of Technology atmospheric chemist suggests that losses of natural gas—our "cleanest" fossil fuel—into the atmosphere may be a larger source than previously recognized.
Oil and gas remain primary power sources for both personal and industrial use worldwide. Extraction of these fuel resources from underground reservoirs involves complex geomechanical processes, and can result in subsidence of the ground over a reservoir. Since this occurrence can have an impact on the environment and affect the operability of extraction equipment, it needs to be accurately predicted and kept within safe limits.
The diesel-burning locomotive, the workhorse of American railroads since World War II, will soon begin burning natural gas—a potentially historic shift that could cut fuel costs, reduce pollution and strengthen the advantage railroads hold over trucks in long-haul shipping. Rail companies want to take advantage of booming natural gas production that has cut the price of the fuel by as much as 50%.
In an effort to put to good use natural gas (methane) that might otherwise become pollution, Lawrence Livermore National Laboratory is collaborating with start-up company Calysta Energy on a new technology to convert natural gas to liquid fuel. The process involves taking natural gas from oil and gas operations, and converting it to methanol that can be used as a fuel or converted to other useful chemicals.
The debate over exporting liquefied natural gas is intensifying as the Energy Dept. considers an array of applications to ship the fuel to Japan, India and other countries where prices are far higher than in the United States. Some large manufacturers that use natural gas say the department is moving too quickly to approve gas exports, pushing the U.S. into a "danger zone" that could raise prices and harm the economy.
Scientists at The Univ. of Texas at Austin have developed a new method to estimate gas production from hydraulically fractured wells in the Barnett Shale. The approach, which uses a simple physics theory called scaling, is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.
