Experimental study on thermochemical composite flooding mechanism of extra heavy oil reservoirs with erosion channels

Frontiers in Energy Research
During the steam flooding of extra heavy oil, expansion of steam chamber is difficult and erosion channels appear, which is different from conventional heavy oil.

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Welfare assessment of gas-filled foam as an agent for killing poultry [PDF]

, 2010
During outbreaks of notifiable diseases in poultry measures are taken to restrict the spread of the disease. Mass on-farm killing of birds using gasfilled foam is such a measure.

Novel cationic surfactants for CO₂-foam flooding in carbonate reservoirs [PDF]

, 2015
textA majority of oil throughout the world is contained in carbonate reservoirs. Alkaline-Surfactant-Polymer (ASP) floods cannot be applied in many carbonate reservoirs for three main reasons: conventional alkali are not compatible with divalent ions ...

Burying Futures: Artisanal Mining Deaths and the Politics of Negligence in Zimbabwe

American Anthropologist, EarlyView.
ABSTRACT In the gold‐mining town of Kwekwe, central Zimbabwe, injury and death are a constant presence. Collapsing shafts, sudden explosions, gang fights, and neglected health infrastructure characterize the everyday lives of the town's impoverished residents.

Gaining ground: survival of native estuarine fauna exposed to recycled glass sand, a potential material for coastal restoration

Restoration Ecology, EarlyView.
Abstract Objectives The aim of this research is to develop an understanding of the potential for using recycled glass sand as a resource for restoring Louisiana's coastline by testing the effects of exposure of native estuarine fauna to recycled glass sand and other sand treatments in a laboratory environment.

A Comparative Study of Gas Flooding and Foam-Assisted Chemical Flooding in Bentheimer Sandstones

Transport in Porous Media, 2019
A laboratory study of principal immiscible gas flooding schemes is reported. Very well-controlled experiments on continuous gas injection, water-alternating-gas (WAG) and alkaline–surfactant–foam (ASF) flooding were conducted. The merits of WAG and ASF compared to continuous gas injection were examined.
