simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
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. ...
Laboratory Evaluation of the Dual-Probe Heat-Pulse Method for Measuring Soil Water Content
to evaluate the level of accuracy and precision that can be achieved with the DPHP method. Tarara and Ham The dual-probe heat-pulse (DPHP) method provides a means of (1997) conducted a laboratory experiment in which estimating volumetric soil water content ( ) and change in volumetric water content ( ) from measurements of volumetric heat capacity. DPHP-based estimates were compared with values...
متن کاملTranslating aboveground cosmic-ray neutron intensity to high-frequency soil moisture profiles at sub-kilometer scale
Above-ground cosmic-ray neutron measurements provide an opportunity to infer soil moisture at the subkilometer scale. Initial efforts to assimilate those measurements have shown promise. This study expands such analysis by investigating (1) how the information from aboveground cosmic-ray neutrons can constrain the soil moisture at distinct depths simulated by a land surface model, and (2) how c...
متن کاملMeasuring soil moisture content non-invasively at intermediate spatial scale using cosmic-ray neutrons
[1] Soil moisture content on a horizontal scale of hectometers and at depths of decimeters can be inferred from measurements of low-energy cosmic-ray neutrons that are generated within soil, moderated mainly by hydrogen atoms, and diffused back to the atmosphere. These neutrons are sensitive to water content changes, but largely insensitive to variations in soil chemistry, and their intensity a...
