What impact does changing the pore fluid from water to oil have on the rock properties? SIP provides the answer.
In order to understand rock and fluid property responses in the subsurface we employ petrophysical analysis of well log data for variations in fluid types, pressure, temperature, porosity and lithology.
This analysis highlights the impact on the bulk rock frame of changing fluid type, porosity, or lithology. The example below shows the impact on Acoustic Impedance and Poisson’s Ratio logs when reservoir fluid is changed from Brine (red) to oil (yellow) and then gas (blue).
The results from fluid replacement modelling at the well can then be used to develop forward predictive models for exploration and development projects, including time-lapse studies, and up-scaled using AVO modelling.
