A mature understanding of the sandstone gas reservoir in the Xiaoheba Formation in the southeastern Sichuan Basin remains lacking. To assess the reservoir characteristics and the origin of the high-quality reservoir in the Xiaoheba Formation, this paper uses systematic field investigations, physical property analysis, thin section identification, scanning electron microscopy and electron microp...
Permeability is a crucial parameter for enhancing shale oil recovery through CO2 injection in oil-bearing shale. After injected into the reservoir, corrosion and adsorption-induced strain can change permeability of shale, affecting oil. This study aimed to explore influence on The deformation internal pore diameter induced by under different pressures was measured low-pressure nitrogen gas adso...
By using the data of logging, cuttings thin section identification and analysis in study area to four characteristics Nantun Formation reservoir their relationship, lower limit standard effective physical property is established by logging interpretation model mud content, porosity, permeability saturation, mercury injection method, oil production test method cumulative frequency statistics met...
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
In this study, it was aimed to investigate the porosity / compactness of the knitted structures made from cotton and modal yarns and to evaluate the air permeability property for sportswear. In the experimental section, cotton and modal yarns spun in different counts ( Ne 30, Ne 40 ) with the same twist coefficient of αe = 3.53 and 3.3 respectively were knitted as single jersey fabrics in the s...
For obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as X-ray computed tomography, CT, seems to be precise and accurate. Porosity is deducted from the CT image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. More than one hundred samples with carbonate li...
This paper describes the application of a new methodology to estimate permeability of clastic rock formations based on the numerical simulation of the physics of mudfiltrate invasion. The methodology assumes a key well with a complete suite of well logs and rock-core laboratory measurements of porosity, permeability, capillary pressure, and relative permeability. For additional wells in the sam...
Aging in super glassy polymers such as poly(trimethylsilylpropyne) (PTMSP), poly(4-methyl-2-pentyne) (PMP), and polymers with intrinsic microporosity (PIM-1) reduces gas permeabilities and limits their application as gas-separation membranes. While super glassy polymers are initially very porous, and ultra-permeable, they quickly pack into a denser phase becoming less porous and permeable. This...
