摘要:
The invention concerns a method for determining the porosity of an earth formation penetrated by a borehole. The method comprises conveying a tool along said borehole, wherein the tool comprises a source of neutron radiation and at least two detectors axially spaced from said source at at least two different spacings. At least one near detector and at least one far detector are selected and a correction computed. The porosity of the earth formation is determined by correcting the far detector porosity with the computed correction.
