Natural gas is currently the number three fossil fuel in terms of share of the global primary energy mix and for years the world has debated the potential for natural gas to play a critical part in building a more resilient and sustainable energy future. While the demand outlook is currently uncertain, advances in supply side technologies for unconventional resource development, led by advances in US shale gas operations, have changed the supply landscape and created new prospects for affordable and secure supplies of natural gas. Continued demand for oil- and gas-based energy services ...

The geologic structure in which petroleum has been trapped and has accu-mulated, whether it was the source rock or the rock to which petroleum has migrated, is called the petroleum reservoir. Predictions of future shortages of oil began shortly after commercial production started in the late nineteenth century. In the first half of the twentieth century, there was national concern about imminent and irreversible shortages of oil on at least six occasions. In the 1950s M. King Hubbert, a geophysicist at Shell Development Company in Houston, developed a model of a cycle of production of ...

The concern is reinforced due to Europe’s dependence on oil and gas from other regions. In addition, many commentators fear domestic oil and gas resource depletion will produce significant supply scarcities in the short term, i.e., well before 2020. Thus, the purpose of this analysis is to address the subject by estimating conventional and unconventional oil and gas supply cost curves for the region. Recent years have seen increasing attention being paid to the broad issues of energy security and climate change, which are of the utmost importance for the European Union and its member ...

fighting poverty must be a global issue, so here are some articles from many economists and experts that introduce some solutions to this crisis

A revolutionary invention in 1909 greatly increased the depth of wells that could be drilled. The original drilling technology, adapted from water well drilling, was to drop a heavy “bit” onto the rock. The rock would shatter and be periodically removed by a scoop. This method is slow, inefficient and not feasible below a thousand meters or so. The far more efficient continuous hydraulic rotary drilling system used today was invented by Hughes Tool Co. c. 1900. It consisted of a rotary cutting tool at the bottom end of a pipe, which was rotated as a whole by an engine at the top. A ...

Oil and gas resources have provided much of the world’s energy in the twentieth century and are expected to be an important part of the energy mix well into the twenty-first century. Currently, oil and gas provide approximately 63 % of primary energy consumption in Europe. However, energy security in the region remains a concern. In the mid-nineteenth century, mineral oil entered the market as an energy source. Refined oil in the form of petroleum and kerosene, for instance, rapidly gained a foothold in the lighting industry. At the time, oil deposits were much fewer in number than coal ...
