A Brief Review of Capillary Number and its Use in Capillary Desaturation Curves

نویسندگان

چکیده

Abstract Capillary number, understood as the ratio of viscous force to capillary force, is one most important parameters in enhanced oil recovery (EOR). It continues attract interest scientists and engineers, because nature quantification macroscopic forces remain controversial. At least 41 different numbers have been collected here from literature. The enters crucially into desaturation experiments. Although length scale dependent, not all definitions number depend on scale, indicating potential inconsistencies between various applications publications. Recently, new appeared subject be actively discussed. Therefore, a short review seems appropriate pertinent.

Positive Coupling Effect in Gas Condensate Flow Capillary Number Versus Weber Number

Positive coupling effect in gas condensate reservoirs is assessed through a pure theoretical approach. A combination of linear stability analysis and long bubble approximation is applied to describe gas condensate coupled flow and relative permeability, thereof. The role of capillary number in gas condensate flow is clearly expressed through closed formula for relative permeability. While the m...

Renal Capillary Hemangioma Mimicking Urothelial Carcinoma, A Case Report and Review of the Literature

Renal hemangioma is a rare tumor which can be capillary or cavernous. There have been less than 30 renal capillary hemangioma cases reported in the English literature. Herein we will report a case of renal hemangioma which was detected in a 74-year-old man operated with the impression of urothelial carcinoma of hilum.

An Efficient Method for Determining Capillary Pressure and Relative Permeability Curves from Spontaneous Imbibition Data

In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed method, a cuboid with an identical core plug height is considered. The equal dimensions of...
