Permeability Measurement in Core Flooding Tests

Why is it important to carry out core flooding tests for permeability measurement at high temperatures?

To make the pore spaces more accessible for testing
To reduce the viscosity of the crude oil for accurate measurements
To ensure the wax deposition does not alter the internal geometry of the pore network
To prevent paraffin deposition in the pore spaces when using very waxy crude oil at room temperatures (correct)

What might happen if wax deposition takes place in the pore spaces during core flooding tests?

The internal geometry of the pore network might be temporarily altered (correct)
The viscosity of the crude oil might decrease
The permeability measurement accuracy might increase
The porosity of the rock might decrease

How can deposited wax be removed from the pore spaces during core flooding tests?

By adding a solvent to dissolve the wax
By reducing the temperature gradually
By increasing the pressure in the core sample
By using high temperatures (correct)
