...). As the pressure drops, more and more gas evolves from the oil into the gaseous phase. Figure 3 shows the pressure, oil viscosity, Kro and Gas saturation profiles along horizontal section as a result of the gas being release when pressure decreases at pseudo steady state. The oil viscosity reaches a maximum...

... conducted on different Buff Berea sandstone cores at both 77 and 250°F. CO 2 gas was injected with the different solutions simultaneously to generate foam with 80% quality. The pressure drop across the core was then measured to estimate the MRF. The results of this work show that foam half-life decreases...

...) connecting a low permeability matrix (~100 nD). We studied multiple wells in the history match (HM), using separator pressure and choke size as the control variables for the wells, and rates and pressures as comparison variables. A multi-segmented well approach was used to describe the pressure drop inside...

After that it is possible to apply the principle of differential pressure because of difference of densities between ambient air and flue gases, called chimney effect or natural draught. This phenomenon allows to compensate the pressure drop due to the increase of the length of line...

The axial cyclone separator consists of a flow conditioning section, as will generator section and a segregation section. Finally, a total of 72 points were valuated...

... Abstract Condensate banking refers to the formation of condensate around the well when the reservoir pressure drops below the dew point value during depletion. As a consequence, the gas relative permeability reduces, and the formation of two phases occurs in the reservoir. Various analysis have...

Incorporating with frictional and acceleration pressure drops, a mathematical model with finite horizontal well conductivity (HWC) was established. Employing Laplace transform, the mathematical model was solved. Transient pressure solutions of MFHW were...
