The biofuel mix in transport in the UK must be increased from currently exploited 3.33% to the EU target mix of 10% by 2020. Under the face of this huge challenge, the most viable way forward is to process infrastructure-compatible intermediate, such as bio-oil from fast pyrolysis of lignocellulosic biomass, into biofuels. New facilities may integrate multiple distributed pyrolysis units produc...

We investigate the effect of different saturation histories relevant to various oil displacement processes (including secondary and tertiary gas injections) on three-phase gas/oil/brine relative permeabilities of water-wet sandstone. It is found that three-phase water (wetting phase) relative permeability is primarily a function of water saturation and shows no dependency upon saturation histor...

Virtually all of the published correlations for solution gas-oil ratios for pressures at and below bubblepoint pressures suffer from two major deficiencies. First, calculated values of solution gas-oil ratios do not match the concave up, point of inflection, concave down shapes as pressure declines below the bubblepoint that are evident in experimental data, especially at high initial solution ...

Carbon-chain length and degree of saturation of dietary fat may influence weight gain. To examine this hypothesis we randomly allotted 100 male, 30-day old, albino rats to each of four groups. Each group was fed, ad libitum, a diet containing, as the only source of fat, either lard (L) or safflower oil (SO) (representing saturated and polyunsaturated fat respectively) or groundnut oil (GO) or c...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a eld with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the eld such that the total production of oil from the eld is maximized. This paper describes a non-linear optimization problem with constra...

With the development of strategic oil and gas assets, massive spatiotemporal oil and gas data have been accumulated. Application systems that assist in the storage and management of the voluminous and complex oil and gas datasets are in high demand. The voluminous and various data should be leveraged and turned into information for business decision-making and operation assistance. In this pape...
