The behavior of four inflow performance relationships are analyzed and discussed. Two of them are developed for petroleum systems and two others are developed for geothermal fluid containing high and low salinity respectively. A methodology to determine the maximum flow rate (Wmax) that a well can produce for a specific stage of its productive life, using these inflow relationships is presented...

Background The normal pattern of left ventricular (LV) inflow and ejection of affects the efficiency of cardiac pumping performance. Altered inflow direction due to a corrected atrioventricular septal defect (AVSD) may disturb this pattern leading to decreased efficiency. We aimed to quantitatively describe the LV blood flow pattern using 4-dimensional velocity-encoded cardiac magnetic resonanc...

J. V. VOGEL MEMBER A/ME In calculating oilwell production, it has commonly been assumed that producing rates are proportional to drawdowns. Using this assumption, a well's behavior can be described by its productivity index (PI). This PI relationship was developed from Darcy's law for the steady-state radial flow of i1 single, incompressible fluid. Although Muskat pointed out that the relations...

Accurate real-time reservoir inflow forecasting is an important requirement for operation, scheduling and planning conjunctive use in any basin. In this study, Time Delay Artificial Neural Network (TDANN) models, which are time lagged feed-formatted networks with delayed memory processing elements at the input layer, are applied to forecast the daily inflow into a planned Reservoir (Almopeos Ri...

The main purpose of this paper is to analyze the sensitivity of system parameters to the performance of the Organic Rankine Cycle (ORC) system quantitatively. A thermodynamic model of the ORC system for binary-cycle geothermal power plants has been developed and verified. The system parameters, such as working fluid, superheat temperature, pinch temperature difference in evaporator and condense...
