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 ...
متن کاملSeparation of Ibuprofen Enantiomers by Diastereomic Salt Formation and Precipitation in Supercritical Carbon Dioxide
The aim of the investigation is to validate the potential of SAS crystallization process to resolve racemic ibuprofen. The resolution is performed via diastereomic salt formation and subsequent salt precipitation in a supercritical CO2 environment. Firstly, the operating conditions, using (S)-α-methylbenzylamine as resolving agent, were optimized. Secondly, the measurement of the binary phase d...
متن کاملCapillary-driven Solute Transport and Precipitation in Porous Media during Dryout
Formation drying and salt precipitation due to gas injection or production can have serious consequences for upstream operations in terms of injectivity and productivity. Recently evidence has been found that the complexity of the pore space and the respective capillary driven solute transport plays a key role for the relationship of permeability and porosity. In this study, we investigate dryo...
متن کاملAn Experimental Study of CO2-low Salinity Water Alternating Gas Injection in Sandstone Heavy Oil Reservoirs
Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on mechanism of IFT reduction due to pH uprising. No bright evidence in literature suppo...
