Abstract: In the field of wellbore data logging it is known to use isotopic neutron sources in a neutron capture logging technique. However, continuous isotopic sources are unpopular for regulatory and safety reasons. Attempts to employ neutron generator tubes to generate neutron bursts for use in the neutron capture technique have encountered various difficulties in areas connected with signal identification and processing. The disclosure relates to a method of data logging in which a low burst rate neutron generator tube is pulsed at comparatively low rates to generate neutron bursts that are captured in atomic nuclei in a proximal formation. The gamma radiation arising from the neutron capture is detected over a gating intervals defined by temporally distinct points. The gamma detector output is integrated over the gating interval to provide a measure of the decay rate that is independent of the pulse rate. Consequently the signal processing problems do not arise.

Abstract: A sizing processing system according to the present invention generates an offset figure based on an offset point set obtained by offsetting the respective sides of a source figure by a distance equal to a prescribed sizing amount. When an inside-out side is detected on the offset figure, two sides of the source figure that intersect at a vertex thereof associated with the detected inside-out side are translated by a distance equal to the prescribed sizing amount, and the respective end points of the thus translated sides corresponding to that vertex are taken as offset points. Then, the offset points are added to the offset point set to generate an offset figure that does not entail the generation of an inside-out side. This can also address the problem of an inside-out side that occurs when an edge cut is inserted in the offset figure.
