TL;DR: Based on the thermodynamic stability and hydrogen bond mechanisms, alkyldibenzothiophene molecular ratios were used to characterize organic maturity and oil migration, which can act as molecular tracers for the filling orientation and pathway in oil reservoir.
Abstract: Based on the thermodynamic stability and hydrogen bond mechanisms, alkyldibenzothiophene molecular ratios, 4-/1-MDBT, 2,4-/1,4- and 4,6-/1,4-DMDBT, are used to characterize organic maturity and oil migration, which can act as molecular tracers for the filling orientation and pathway in oil reservoir. The application of aforesaid molecular parameters, in a Neogene sandstone reservoir of the XJ24-3 Oilfield, Zhujiangkou Basin and in an Ordovician carbonate reservoir of Karst pore-fissure-network type in the Tahe Oilfield, Tarim Basin, manifests that those ratios are reliable tracers compared with other molecular ratios, and thus, alkyldibezothiophene parameters may be used in a wide range of maturity, especially for high- to post-mature oil and severely biodegraded oil, both of which are short of effective molecular parameters.

TL;DR: In this paper, an improved numerical model was developed to simulate the oil recovery by microbial flooding under non-isothermal conditions, and the model showed that the microscopic oil displacement efficiency increases with the increase in mean fluid velocity and reaches a threshold maximum oil displacement just before the water breakthrough at relatively lower temperature.

TL;DR: In this article, a new interpretation of West Moorcroft field (Mettler, 1966) suggested an origin as point-bar sand deposited in a meandering stream channel with the updip permeability barrier provided by a clay-filled, abandoned channel.
Abstract: Proved oil reserves of more than 40 million bbl have been found in the Lower Cretaceous Fall River Sandstone on the northeast flank of the Powder River basin. Most of the oil is in stratigraphic traps on gentle regional dip of about 2° SW. Fall River reservoir sandstone formerly was believed to have been deposited as barrier bars with the updip permeability barriers provided by lagoonal shale. A new interpretation of West Moorcroft field (Mettler, 1966) suggested an origin as point-bar sand deposited in a meandering stream channel with the updip permeability barrier provided by a clay-filled, abandoned channel. This interpretation is applicable to other Fall River oil fields, as shown by distribution of sandstone at Coyote Creek and Miller Creek fields. On the basis f thickness of permeable sandstone, a pattern is present which is remarkably similar to that of point-bar, swale, and channel deposits of recent stream-meander belts. Recognition of these distinct facies will aid in exploration for new fields, in development drilling within fields, and in planning for secondary recovery projects.

TL;DR: The Turner Valley field is comprised of two Laramide (FOOTNOTE 3) structures, the Turner Valley and Millarville thrust sheets, the latter overriding the down-plunging north extension of the former as discussed by the authors.
Abstract: The Turner Valley field is comprised of two Laramide (FOOTNOTE 3) structures, the Turner Valley and Millarville thrust sheets, the latter over-riding the down-plunging north extension of the former. The ancestral fold and age of accumulation are pre-Jurassic and pre-Blairmore. The reservoir rock is a dolomitic biostrome identified by the abundance of detrital crinoids et cetera which form the porous zones and provide source. This relationship between the early accumulation and the age of folding, together with the organic origin of the reservoir, is significant in prospecting for oil in the Paleozoic rocks of the Foothills and Western Plains areas.
