Nonlinear Young’s Modulus of New Red Sandstone: Experimental Studies

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. ...

Experimental Study of Cement - Sandstone/Shale - Brine - CO2 Interactions

BACKGROUND Reactive-transport simulation is a tool that is being used to estimate long-term trapping of CO2, and wellbore and cap rock integrity for geologic CO2 storage. We reacted end member components of a heterolithic sandstone and shale unit that forms the upper section of the In Salah Gas Project carbon storage reservoir in Krechba, Algeria with supercritical CO2, brine, and with/without ...

the effectiveness of strategy-based instruction in teaching english as a second or foreign language: a meta-analysis of experimental studies

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...

Proposal for Experimental Studies of Nonlinear Quantum Electrodynamics

New and Notable Modeling Nonlinear Red Cell Elasticity

The remarkable elasticity of red cells shows up under a variety of conditions both in vivo and in controlled experiments on single cells. Squeezed through narrow capillaries with diameters significantly smaller than the cells themselves, they perfectly recover their biconcave resting shape countless times during their life cycle of about 100 days in the circulatory system. Likewise, this normal...
