Reserves estimations in natural gas markets are fundamental for decision making of private and public agents. When markets are mature, market signals such as demand growth, costs, and price expectations activate exploration and new reserves are continually added to the proven reserves base. We can describe the process of discovering new reserves in a market with a simple dynamic hypothesis in w...

Increasing the density of natural reserves in the forest landscape may provide conservation benefits for biodiversity within and beyond reserve borders. We used 2 French data sets on saproxylic beetles and landscape cover of forest reserves (LCFR) to test this hypothesis: national standardized data derived from 252 assessment plots in managed and reserve stands in 9 lowland and 5 highland fores...

The ever-increasing demand for new energy sources witnessed at present is leading to a shortage of oil and gas resources throughout the world. At same time, polluting such as coal are being gradually replaced by gas, fuel types electricity produced renewable methods. Unconventional shale reserves, relying on presence substantial volumes good quality, thermally mature organic matter, therefore c...

Unconventional gas reservoirs have shown the potential to be the next world primary energy resource and have received a lot of attention in the past few years in the world. Even with the significant progress that has been made world-wide towards commercial development of natural gas from these unconventional resources, understandings or modeling tools of gas flow in these extremely low-permeabi...

The effect of sugar feeding on egg-batch size in Aedes aegypti was examined in a way that would distinguish between the roles of a recent sugar meal (full vs. empty crop) and of repeated sugar feeding and digestion (high vs. low energy reserves). Egg numbers of females representing the four combinations of these characteristics (full crop/high reserves, full crop/low reserves, empty crop/high r...

www.frontiersinecology.org © The Ecological Society of America T number of marine reserves is growing worldwide (Wood et al. 2008), so it is prudent to consider how to assess whether such reserves achieve their goals. The stated goals of marine reserves vary widely, but fundamentally all reserves are designed to achieve some combination of preserving biodiversity and supporting sustainable fish...

BACKGROUND Reserves are the principal means to conserve forests and biodiversity, but the question of whether reserves work is still debated. In the Amazon, fires are closely linked to deforestation, and thus can be used as a proxy for reserve effectiveness in protecting forest cover. We ask whether reserves in the Brazilian Amazon provide effective protection against deforestation and conseque...

Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...

Shale gas reservoirs have huge amounts of reserves. Economically evaluating these reserves is challenging due to complex driving mechanisms, drilling and completion configurations, the complexity controlling producing conditions. Decline Curve Analysis (DCA) historically considered easiest method for production prediction unconventional as it only requires history. Besides uncertainties in sele...

Abstract Kuwait has proven conventional oil reserves of about 100 billion barrels which makes it one the major oil-producing countries worldwide. Most this reserve is found in Cretaceous and Jurassic with minor quantities Paleogene sedimentary successions. hydrocarbon production comes from siliciclastic Burgan Formation most important reservoir Kuwait. The Lower exhibit good quality source rock...
