Flexible US shale industry is changing world gas trade

A cargo of LNG hauled from Louisiana in late December has become a symbol of how global trade is changing for a fuel increasingly seen as a cheap, cleaner-burning option for countries from Latin America to China and India, Bloomber reports. The tanker Maran Gas Achilles passed through the Panama Canal and was headed toward Asia at…

Oxford Institute for Energy Studies: new paper shows subtle shale well productivity gains

The Oxford Institute for Energy Studies (OIES) has published PetroNerds’ new research paper, “Unravelling the US Shale Productivity Gains,” authored by PetroNerds co-founders Trisha Curtis and Ben Montalbano. “Unravelling the US Shale Productivity Gains” examines the significant year-over-year well productivity gains that have been generated in several prominent US shale and tight oil plays since the beginning of…

US shale oil well output decline rates slowing

Since the beginning of the U.S. fracking revolution, oil producers have struggled with a frustrating issue: after an initial burst, crude output from new shale wells falls much faster than from conventional wells. However, those well decline rates have been slowing across the U.S over the past few years, according to data analysis provided exclusively…

US researchers experiment using liquid nitrogen instead of water in fracking

Gas fields in the US state of Colorado soon may serve as a laboratory for testing a different way to fracture shale rock formations – one that doesn’t pump millions of gallons of water underground or yield contaminated wastewater. As activists rekindle efforts to ban hydraulic fracturing in the state, petroleum engineers in Colorado are…

Improved techniques open up prospects for re-fracking in major US shale plays

Tens of thousands of oil and gas wells have been drilled and hydraulically fractured in recent years as part of the shale boom that has spread across the US. Now improved techniques and with a few years of experience under their belts, the leading US oil field service companies are in the early stages of…

MIT develops new process that cleans contaminated water from shale oil wells

In a nondescript site in Midland, Texas, a cost-effective new process is cleaning up some of the most contaminated water around—the extremely salty stuff that comes up with oil at wells. By the end of next month the technology is expected to be chugging 500,000 gallons per day, furnishing water that’s sufficiently clean to use…
