Capillary pressure curve and liquid permeability estimation in tight oil reservoirs using pressure decline versus time data
… to estimate saturation profiles and capillary pressure curves in conventional rocks, but these methods fail in tight rocks because of the complexities inherent in these types of reservoirs. This report presents a new method that makes use of the pressure decline versus time data to estimate the …

Nonequilibrium phase Behaviour and Mass Transfer of Alkane Solvents(s)-CO2-Heavy Oil Systems Under Reservoir Conditions
… a constant volume expansion rate and a constant pressure decline rate, respectively. Experimentally, constant-composition expansion (CCE) tests have been conducted for alkane solvent(s)–CO2–heavy oil systems with a PVT setup, during which not only pressure and volume are simultaneously monitored …

Study on the Feasibility of Nitrogen Huff-N-Puff in Heavy Oil Reservoirs
… increase of 5 ℃, and each temperature has four pressure setting of 3 to 8 MPa. It was found that nitrogen has a lower solubility than carbon dioxide and methane. The solubility of nitrogen in the oil sample at 50℃ and 7 MPa is 7.6 m3/m3. The second category is the pressure depletion tests …

A streamline model application for the waterflood performance of NZ-OF-HRL carbonate reservoir
… in place, mainly by internal gas drive, when the pressure had declined from the original pressure of 4,781 psig to 4,009 psig to 8,750 feet. As a result of such rapid change in pressure and due to the fact that energy contribution from the aquifer appears to be negligible, the possibilities of …

Assessing the Impact on Hydrocarbon Production from Tight and Shale Plays by Depletion and Injection Using Thermodynamic and Transport Properties from Confined Spaces
… was developed, incorporating capillary pressure and pore size distribution, to provide a comprehensive approach to simulate the effect of confinement in unconventional reservoirs. With the developed mechanistic model, fluid model and pore size distribution models, a series of sensitivity …

The effects of magnesium administration on cardiac ventricular function, heart rate variability, and myocardial morphological changes in a chronic diabetes disease model in rats
… decreased the left ventricular (LV) developed pressure and the maximal rate of LV pressure increase (+dP/dt), and these diabetic effects were prevented by Mg2+ treatment (P < 0.05, STZ+Mg vs. STZ). DM also decreased the maximal rate of LV pressure decline (-dP/dt) and the rate pressure product, …
