In this paper we present empirical facts on oil exploitation and a model that can replicate some of these facts. In particular, we show that the time path of the oil price, on the one hand, and the extraction and discovery rate, on the other hand, seem to follow a U-shaped and an inverted U-shaped relationship, respectively, which is confirmed by simple non-parametric estimations. Next, we pres...

Abstract The acid degumming waste of the seeds oil refining industry is currently disposed of, but, instead, it could be exploited as an important source for preparation many products. In this work, coming from soybean step was first recovered and treated, allowing isolation a fraction enriched phospholipids (PLs). Then, latter transformed, via enzymatic reaction catalysed by phospholipase D (f...

Oil shale can produce oil and gas by heating the at 300–500 °C. The high temperature release of organic matter change physical mechanical properties rocks make originally tight impervious layer become a permeable under in situ exploitation conditions. To realize potential impact on groundwater environments, series water–rock interaction experiments different temperatures was conducted. results ...
