Shale gas is natural gas – mainly methane – trapped within the micropores of shale formations or adsorbed onto the shale (sedimentary rock). In Europe, known deposits exist in the UK, France, the Netherlands, Germany, Poland, the Baltic States and Scandinavia. In Switzerland, deposits are suspected to lie in the Permo-Carboniferous trough of Northeastern Switzerland, below Lake Geneva, and in Lower and Middle Jurassic strata, e.g. in Canton Fribourg. In view of the depletion of conventional energy resources and as a result of advances in drilling technology, the exploitation of shale gas reserves – long considered unviable – now appears to be economically attractive. In Switzerland and in Southern Germany, debates have been prompted by the awarding of concessions north of Lake Constance and the suspension of drilling licences in Canton Fribourg. This factsheet is intended to provide an overview of the current state of scientific knowledge in this area.
Fracking & Shale Gas
Unconventional natural gas production (shale gas) by hydraulic fracturing - Quantification of the Environmental FootprintDue to the global decline of fossil energy reserves and resources, unconventional natural gas production has become increasingly important in the last decade.In this context, unconventional natural gas production means the production of shale gas, tight gas and coal bed methane. A useful approach to determine the environmental footprint of unconventional gas production is Life Cycle Assessment...
Colombian oil revival hopes face electoral test
An upcoming election and auction round will help determine the country`s oil fortunes The outcome of Colombia`s election next week is being watched closely as the country attempts to reverse its sliding oil fortunes, which have suffered since the downturn started in late 2014. Colombians will head to the polls to choose a successor to Juan Manuel Santos on 27 May for the first-round vote, with a run-off likely on 17 June. The most critical issues that the industry will want the next president to address include...
PVC Geomembranes - Good, Better, Best
Are different grades of PVC Geomembranes available or are they all the same? There has been a common misperception in our industry that all polyvinyl chloride (PVC) membranes are the same. The fact is that this is far from the truth and as we explain in this blog there are several different grades, and each has its own specific properties with respect to geomembrane applications. Without providing a “Wikipedia” on polyvinyl chloride, it is one of the most commonly specified lining materials in the...
Oklahoma Oil Industry Eyes Produced Water Reuse Strategies
As the scale of fracking increases, states and operators are rethinking produced water management Hydraulic fracturing, or fracking, is a technique for stimulating production in an oil or gas well by injecting large quantities of pressurized fluid, which creates fissures. Each well is different, but according to StateImpact Pennsylvania, fracking requires an average of 4.4 million gallons of water per well — enough to fill more than six Olympic swimming pools. With persistent drought and water scarcity...
Living near a fracking well means more asthma attacks
It`s probably telling that the word ‘fracking’ sounds just shy of a curse word. Researchers at the Johns Hopkins Bloomberg School of Public Health have found that people who live near active, unconventional natural gas wells operated by the fracking industry were significantly more likely to suffer from asthma attacks. It’s the latest in a string of studies that has linked the fracking industry to health issues including lower birth weights, skin problems and upper respiratory issues. First...
