15 صفحه اولVp-Vs ratio sensitivity to pressure, fluid, and lithology changes in tight gas sandstones
Low Vp/Vs anomalies can assist in prospect identification in tight gas sandstone reservoirs, because they are related to good quality rocks (sandstones with low clay content), presence of gas, and overpressure conditions. In such rocks, gas saturation lowers Vp/Vs and the effect is larger if the gas is overpressured. On the other hand, with water saturation, Vp/Vs increases and the effect is en...

15 صفحه اول15.2 Common Issues in Petrophysical Analysis of Tight Gas Sandstones
We discuss petrophysical analysis of wireline logs, methods for formation evaluation and issues in evaluating tight sandstone formations. The main concerns of log interpretation in tight gas sandstones include porosity interpretation, understanding the effect of clay on the log responses, accurate computation of water saturation, and permeability determination (Kukal et al., 1985). Moreover, va...
متن کاملEffect of three different sanitizing solutions on the contaminated bone: an experimental study in the rabbit
Background: To determine the efficacy of three different antiseptic solutions (Control group (I), Antibiotic solution – Neomycin and polymyxin (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in disinfecting contaminated bone fragments. Methods: Under sterile conditions, the femora of 12 rabbits were removed and cut into six millimeter pieces. A total of 200 bone specimens were ...
