...Results & Discussions This study will investigate the wettability contact angle of several pore systems, such as, pore body, pore throat, nano-pore, and finally natural fracture pore system ( Figures 2 - 7 ). The six reservoir candidates use big data electron contact angle measurements...

... Throat Space Shale reservoir pore throat space is characterized by complex and multi-pore size connectivity structures and relatively complex chemical components, which produce significant complications when studying the oil-water component accumulation and migration in pore throat structures...

... fluid is now commonly used in this area. As small size pore throat, high clay content and water lock, this gas deposit is sensitive to treatment fluid, thus the flowback time of fractured well is very long and production is generally low. In this paper we introduce a new fracturing fluid which can...

... as absorbed gas on pores surface. The effect of gas adsorption is generally ignored in conventional reservoirs. However, the absorbed gas has to be taken into consideration for shale gas production because of its huge amount in nanoscale porous media. The smaller the pore throat radius, the more significant...

... petrophysics were analyzed. New formation evaluation parameters for low permeability carbonate reservoir are proposed involving mean pore-throat radius, movable oil saturation and threshold pressure gradient. Results of the MICP indicated that there mainly 6 type pore-throat distribution. Good exponentiation...

.... In fact, there are no causative relationships among the calculated parameters. Recent developments are marked by the use of pore throat size distribution for relating porosity to permeability (Winland and Pittman equations). The equations are theoretically correct but they are actually established...

... by changing wettability induced by adsorption of polysilicon on the porous surface of sandstone. On the other hand, the adsorption on the porous surface and plugging at the small pore throats of the polysilicon may lead to reduction in porosity and absolute permeability ( K ) of porous media for pore sizes...
