Mechanisms and Possibility of Autocatalytic Criticality by High-Level Wastes Buried in Water-Saturated Geologic Formation

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. ...

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

A pressure-induced strength transition in water-saturated geologic materials

Porous, water-saturated geologic materials exposed to shock wave loading should undergo a gradual transition from a Terzaghi solid to a much stronger and stiffer material as the confining pressure increases over the range of about 0.2 GPa to about 2 GPa. This transition can thus be expected to become important in cases such as high explosive or nuclear cratering events in which ground shocks in...
