An experimental study on the CO2/sand dry-frac process
Natural Gas Industry B, 2014 The CO2/sand dry-frac process is a waterless fracturing technology in which CO2 instead of water is used as fracturing fluid. The application of the technology abroad (in the USA and Canada) shows that it works well in stimulating low-pressure, low ...

Haiti-Drill: an amphibious drilling project workshop [PDF]
Scientific Drilling, 2020 Abstract. The Haiti region – bounded by two strike-slip faults expressed both onshore and offshore – offers a unique opportunity for an amphibious drilling project. The east–west (EW)-striking, left lateral strike-slip Oriente–Septentrional fault zone and Enriquillo–Plantain Garden fault zone bounding Haiti have similar slip rates and also define the ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
