Tracer responses in gas-liquid, two-phase flow through a fractured layer are discussed. Experiments were carried out using a glass bead bed in a cylinder. In the results, over a wide range of flow conditions of particle size, fluids-flow velocity, and water saturation (Sw), one of three types of liquidand gas-flow pattern was obtained: a single-phase (water) flow with entrapped gases, a bubble ...

6 Release of gases from intermediate level radioactive wastes encapsulated in cement-based wasteform grouts is a 7 major concern during the interim storage, transportation and operational stage of a phased geological repository 8 system. The ability of the wasteform grout to retain radioactive gases depends on its mass transport properties, 9 which evolve with age, water saturation degree and a...

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

The monitoring of intestinal oxygen saturation by means of a pulse oximeter is routinely applied in human medicine during surgery of the gastrointestinal tract to evaluate the disturbance of perfusion and assess tissue viability. To some extent, this technique has been applied in veterinary medicine. The purpose of this study was to test the technique in cattle and to describe the influence of ...

We use a three-dimensional mixed-wet random network model representing Berea sandstone to compute displacement paths and relative permeabilities for water alternating gas (WAG) flooding. First we reproduce cycles of water and gas injection observed in previously published experimental studies. We predict the measured oil, water and gas relative permeabilities accurately. We discuss the hysteres...

Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...

Seismic amplitudes contain important information which can be related to fluid saturation. The amplitude-versus-offset (AVO) analysis of seismic data based on Gassmann’s theory and approximation of the Zoeppritz equations, has played an central role in reservoir characterization. However, this standard technique faces a long standing problem, its inability to distinguish between partial gas and...
