Scientists used drones, infrared cameras and portable isotope spectrometers to study gas emissions from volcanoes in the South American Andes. Researchers are trying to gain a better understanding of volatile recycling by measuring the amount of volatiles released into the atmosphere from subduction zones.
Researchers will use additional seismic monitoring stations to study earthquakes in Texas, seismology experts said last week. The Texas Seismological Network stations aim to increase understanding of the region's seismic activity, some of which has been linked to wastewater injection.
Activity at the Haynesville Shale in northwest Louisiana and eastern Texas dropped off in recent years because of lower-cost natural gas supplies elsewhere, but activity has been renewed thanks to pipeline complications in the Northeast. Gas rates have gone up and rig counts have increased to 37 since November at the formation, which produces about 6.3 billion cubic feet of gas per day and is estimated to hold almost 500 trillion cubic feet.
A new book published by the American Geophysical Union examines fault zones in the eastern Mediterranean region and looks at potential ways to improve earthquake prediction. The book discusses neotectonics, which uses geological and geophysical techniques to determine tectonic plate movement before an earthquake occurs.
The State Department approved a construction permit for TransCanada's Keystone XL pipeline project on Friday after being first proposed in 2008. TransCanada still needs to secure approvals from states, where it might encounter legal hurdles.
US shale producers are leaving thousands of wells unfinished in the Permian Basin, with the number of drilled but uncompleted wells hitting a record of 1,764 in February, government data show. This suggests that rig count data is not a reliable indicator of production as many companies drill wells just because they are forced to do so to retain their leases.
Arctic oil exploration is unjustifiable and infeasible in the current price environment, especially in areas not easily accessible such as Alaska, said Goldman Sachs commodities analyst Michele Della Vigna. "Overall, the idea that we have to go into the Arctic to find new resources I think has been dispelled by the enormous cheap, easier to produce and quicker time-to-market resources in the Permian onshore US," he added.
US oil and natural gas companies doubt that President Donald Trump's energy policy will lead to much positive or negative change within the industry, a Reuters analysis of Securities and Exchange Commission reports shows. According to the filings, 13 of the 15 biggest US oil and gas producers say that the current regulatory environment is not affecting their operations or finances.
The 14-member California Air Resources Board on Thursday voted unanimously in favor of adopting new methane emissions rules that are considered the strictest in the US. The regulations establish new efficiency guidelines for natural gas transportation and production and oil-handling equipment, and also introduce tougher gas leak monitoring and reporting requirements.
