Lecture 3: Capillary Pressure 0.0 / 5 ? GeographyReservoir Engineering and Petroleum EconomicsUniversityNone Created by: alishaCreated on: 20-05-17 17:30 What is the klinkenberg effect? velocity is found to be at a maximum at the centre of the tube, and zero at the wall due to viscous forces 1 of 10 Critical Saturation fluid remains immobie until its saturation exceeds a certain saturation, called critical saturation which above the fluid begins to move 2 of 10 Residual Saturation The portion of oil that remains in the reservoir after displacement 3 of 10 Wettability tendancy of preference of a fluid to spread on or adhere to a solid surface to the prescence of other immiscible fluids 4 of 10 Name two types of wettability homogenous or heterogenous 5 of 10 Drainage displacement of the wetting phase from the porous medium b a with a non wetting phase 6 of 10 imbibition wetting phase saturation increases and the non wetting phase saturation decreases 7 of 10 Capillary pressure pressure which exists at the interface between two immiscible fluids in the pores 8 of 10 How do you calculate the capillary pressure? (pressure of non wetting phase) - (pressure of wetting phase) pc = pnw - pw 9 of 10 what is Leverett J- Function capillary pressures obtained from small samples. 10 of 10
