  • Estimation of formation porosity using water measurement
    Patent number: 6894274
    Abstract: Methods and systems for enabling estimations of porosity that are less sensitive to standoff and borehole size effects, and less reliant on corrective techniques for such effects. In one embodiment, a method is provided for estimating porosity of a formation using a downhole neutron tool. The method includes obtaining a near count rate in water, obtaining a far count rate in water, obtaining a near count rate in the formation and a corresponding far count rate in the formation, subtracting the near count rate in water from the near count rate in the formation to form an adjusted near count rate, subtracting the far count rate in water from the far count rate in the formation to form an adjusted far count rate, and estimating a formation porosity value as a function of the adjusted near count rate and the adjusted far count rate.
