Klinkenberg-corrected permeability
Did you know?
In Petrophysics a Klinkenberg correction is a procedure for calibration of permeability data obtained from a minipermeameter device. A more accurate correction factor can be obtained using Knudsen correction. When using nitrogen gas for core plug measurements, the Klinkenberg correction is usually … See more Under steady state and laminar flow condition, Klinkenberg demonstrated that the permeability of porous media to gases is approximately a linear function of the reciprocal pressure. When Klinkenberg … See more Permeability is measured in the laboratory by encasing a core plug of known length and diameter in an air-tight sleeve (the Hassler Sleeve). A … See more WebThe Klinkenberg effect is important when permeability is lower than 10 −18 m 2 and at low differential pore pressures, and its correction is essential for estimating water …
WebN2 - Standard industry practice to correct absolute gas permeability for what is known as the Klinkenberg effect is to perform single point gas permeability measurement and use assumptions or existing correlations. Available correlations for Klinkenberg-correction of gas permeability are based on measurements of sandstone samples. WebJan 28, 2024 · Klinkenberg plots showed that, under constant Pc, gas permeability kg decreased linearly for high values of 1/ Pf, reached a minimum and then sharply increased as 1/ Pf approached zero. Under constant Pc − Pf, kg again decreased linearly in the high limit of 1/ Pf and showed additional decrease in the low 1/ Pf limit.
