abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
background: in this study a series of basic dosimetric properties of a low-density (ld) gel dosimeter are investigated. the dose response is studied regarding to linearity, sensitivity, dose-rate and energy dependence as well as lung tissue equivalence. materials and methods: the ld gel was made by mixing the polymer gel with expanded polystyrene spheres. energy dependence was studied at two d...
