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-Volu...

Previous studies based on measurements made in the ascending aorta have demonstrated that it can be useful to separate the arterial pressure P into a reservoir pressure P* generated by the windkessel effect and a wave pressure p generated by the arterial waves: P = P*+p. The separation in these studies was relatively straightforward since the flow into the arterial system was measured. In this ...

Ayre's T-piece. The Ayre's T-piece (Ayre, 1937) has a very low resistance, is simple, and almost trouble-free. Intermittent positive pressure respiration (IPPR) can be induced by occluding the exhalation reservoir tube intermittently with one finger. However, the pressure, volume, and riming of lung inflation depends on the flow of gases from the anaesthetic machine and the duration of finger o...

I A small plastic bell connected to a reservoir suspended on a strain gauge and to a pressure recorder was fixed over a fistula in the scleral wall of Schlemm's canal. The anterior chamber was similarly connected to a reservoir and a pressure transducer. In a majority of vervet eyes an increase of the pressure in the bell over the intraocular pressure caused a bulk inflow into the canal through...

Permeability and capillary pressures are important petrophysical properties. Permeability is one of the most important parameters for reservoir management and development. Capillary pressure data have been widely used in evaluating reservoir rock, sealing capacity, transition zone thickness, pay versus non pay, and absolute and relative permeability. We are working in this study modification tw...

Controversy exists about whether one-dimensional wave theory can explain the "self-canceling" waves that accompany the diastolic pressure decay and discharge of the arterial reservoir. Although it has been proposed that reservoir and wave effects be treated as separate phenomena, thus avoiding the issue of self-canceling waves, we have argued that reservoir effects are a phenomenological and ma...

30 Controversy exists about whether one-dimensional (1D) wave theory can explain the ‘self31 cancelling’ waves that accompany the diastolic pressure decay and discharge of the arterial 32 reservoir. Although it has been proposed that reservoir and wave effects be treated as separate 33 phenomena, thus avoiding the issue of self-cancelling waves, we have argued that reservoir 34 effects are a ph...

Evaporation process, the main component of the water cycle in nature, is essential in agricultural studies, hydrology and meteorology, the operation of reservoirs, irrigation and drainage systems, irrigation scheduling and management of water resources. Various methods have been presented for estimating evaporation from free surface including water budget method, evaporation from pan and experi...
