Abstract
A method for estimating a depth pressure and/or permeability profile of a geological formation having a well extending between a first end and a second end includes equipping the well with an inner tube defining an inner space and an annular space; performing a first well closing phase by injecting a second fluid having a higher viscosity than a first fluid in the well while extracting under a first constant pressure value; performing a second well closing phase by injecting the second fluid while extracting the first fluid under a second constant pressure value, different from the first constant pressure value; and estimating the depth pressure and/or permeability profile of the geological formation based on measurements performed during the first well closing phase and the second well closing phase.
