Petroleum Reserves and Subjectivity

A Policy of Strategic Petroleum Market Reserves

Unexpected price spikes in petroleum can lead to instability in markets and have a negative economic effect on sectors which rely on petroleum consumption. Sudden rises in the price of petroleum do not have to be long-term to cause negative, cascading impacts across the economy. Firms which make futures purchases or hedge against a higher price during a price spike can become insolvent when the...

Differences in Estimating Reserves between Geothermal and Petroleum Reservoirs

The existing volumetric approach was honored by considering the effects of oil and gas saturations on the evaluation of geothermal resources in oil and gas reservoirs. The main reason to do so was that oil and gas phases may not be simply substituted by water because the values of the specific heat of oil and gas are smaller than that of water. We selected an oil reservoir, Hexiwu, from Huabei ...

The Determinants of Investment in Petroleum Reserves and Their Implications for Public Policy

Oil spills could be cleaned up by bacteria from underground petroleum reserves

Some microorganisms are equipped with enzymes that allow them to degrade, and even live on, chemicals that other species find toxic. For example, many bacteria in the genus Rhodococcus are able to break down polychlorinated biphenyl (PCB), an industrial chemical and environmental pollutant linked to cancer in humans. In a process called ‘bioremediation’, humans can use these micro-organisms to ...

Coyote Control to Protect Endangered San Joaquin Kit Foxes at the Naval Petroleum Reserves, California

We investigated the effectiveness of a coyote (Canis latrans) control program implemented to increase numbers of endangered San Joaquin kit foxes (Vulpes macrotis mutica) at the Naval Petroleum Reserves in California (NPRC). Between 1980 and 1985, the kit fox population on NPRC declined approximately 66% while coyote abundance apparently increased. Coyote predation was identified as the primary...
