- Description
The present report contains a literature review of the key and latest publications on Low Salinity Waterflooding (LSWF) since its real development in the 1990`s to explain the dominant mechanisms, modelling processes and requirements to apply this Enhanced Oil Recovery (EOR) technique. Up-to-date, there is no general agreement of the dominating mechanism that rules the LSWF effectiveness. Currently, wettability alteration to a more water-wet state of the rock as a result of ion exchange and/or double layer expansion mechanism are the two most feasible and supported pore scale mechanisms. However, most of the last published modeling methods are trying to represent the wettability changes only as a result of Multi-Ion Exchange (MIE) processes and geochemical reactions. These methods cross-check their results with observed laboratory data and with the chemical reactions obtained from a recognized geochemical simulator, PHREEQ-C (Kharaka et al., 1988). The present project is oriented to reproduce the experimental results obtained in the IPE laboratory at Heriot Watt University with standard industry reservoir simulation software and validate the outcomes with PHREEQ-C to later define correlations between grid size, cation exchange capacity (CEC), selectivity coefficients, injection rates, and oil recovery in a MIE modelling process in a single phase and two phase system.
El presente estudio analiza el efecto del intercambio i?nico en la recuperaci?n de crudo mediante inyecci?n de agua de baja salinidad. Inicialmente se realiz? un proceso de reproducci?n de datos experimentales a escala de n?cleo para posteriormente probar el proceso en un sistema bif?sico observando el efecto de distintos interpoladores en la recuperaci?n final de crudo.
