Reservoir Engineering Concepts Quiz

Reservoir Engineering Concepts

• Capillary pressure in a reservoir is given by the equation $P_c = \frac{{\gamma}},{{r^2}}$, where $\gamma$ is the interfacial tension and $r$ is the radius of curvature of the meniscus.
• The Young Laplace Equation relates capillary pressure difference between fluids to interfacial tension and principal radii of curvature of the interface.
• Reservoir rock wettability can be water-wet, oil-wet, or mixed-wet, with mixed-wet being a combination of both.
• The likely performance of a reservoir during production depends on factors such as reservoir quality, porosity, and hydrocarbon saturation, with high hydrocarbon production rates being more favorable.
• Gross rock volume in a reservoir is primarily controlled by the shape of the structure, depths of fluid contacts, and facies distributions, rather than the depositional environment.
• Permeability of a reservoir is primarily controlled by the grain size of the reservoir rock, with smaller grain sizes generally resulting in lower permeability.
• Darcy's Law, which describes the flow of fluid through a porous medium, is given by the equation $q = \frac{k \Delta P A},{\mu L}$, involving permeability, pressure difference, cross-sectional area, viscosity, and length of the porous medium.
• The main objective of reservoir appraisal is to estimate the hydrocarbon reserves in the reservoir by assessing the volume of recoverable hydrocarbons and their distribution within the reservoir.
• A Drill Stem Test (DST) in oil exploration is conducted to evaluate the productivity of the reservoir by measuring the flow rate and pressure of the reservoir fluids.
• The net-to-gross ratio in a reservoir is primarily controlled by the depositional environment, which determines the distribution of facies and diagenetic processes affecting the rock.
• The equation for calculating pore pressure in a reservoir is $P_{Hydrostatic} = \rho_{water}gh$, where $\rho_{water}$ is the density of water, $g$ is the acceleration due to gravity, and $h$ is the depth.
• The equation for capillary pressure in a reservoir is $PC = (\rho_o - \rho_w)gh$, where $\rho_o$ is the density of oil, $\rho_w$ is the density of water, $g$ is the acceleration due to gravity, and $h$ is the height above the free water level.
