Abstract In marine and freshwater oxygen-deficient zones, the remineralization of sinking organic matter from photic zone is central to driving nitrogen loss. Deep blooms photosynthetic bacteria, which form suboxic/anoxic chlorophyll maximum (ACM), widespread in aquatic ecosystems, may also contribute local input matter. Yet, influence ACM on carbon cycling remains poorly understood. Using a su...

the emarat pb-zn mine is located at about 80 km south of the city of arak , iran. i the present mine-scale litho geochemical survey 56 hanging wall samples and 37 footwall samples were taken form exploratory tunnels, drillholes and open pit all samples were taken in the range of 0-40 m from pb-zn veins. the relationship between three variables including concentration of zn in wallwork, distance...

A precise identification of pore fluid pressure (PP) is great significance, specifically, in terms drilling safety and reservoir management. Despite numerous work have been carried out for prediction PP oil reservoirs, but there still exists a tangible lack such gas hosting rocks. The present study aims to discuss evaluate the application number existing methods two selected giant carbonate res...

Abstract The Mamuniyat sandstones represent the main reservoir in “A” Oil Field, NC115 Concession, Murzuq Basin of Libya. As a result, primary objectives current work are to evaluate and define Formation’s petrophysical parameters using well-logging analysis. For this study, available data from ten exploratory wells were provided. Several cross-plots used lithologic constituents fluid saturatio...
