Permeability Measurement in Core Flooding Tests

Play an AI-generated podcast conversation about this lesson

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)
