Wettability estimation using magnetic resonance
A method of estimating a wettability characteristic of a formation includes: disposing a magnetic resonance (MR) measurement apparatus in a borehole; generating a low gradient static magnetic field and an oscillating magnetic field in a region of the formation; detecting a MR signal generated in the region; calculating relaxation parameters for at least one fluid in the region; and estimating the wettability characteristic of the region based on the relaxation parameters.
