A new nuclear–physical method and scheme of a device for logging gas and oil wells with the simultaneous determination of the density and porosity of the rocks behind the well are substantiated. Density and porosity are determined by one device. The pulsed neutron irradiation of the medium behind the well was used. Density and porosity are determined by gamma radiation from inelastic scattering and radiation capture of rock–forming elements by two spaced apart gamma spectrometric detectors.

In contrast to the adjustment of single plates a block adjustment is a simultaneous determination of all unknowns associated with many overlapping plates (star positions and plate constants etc. ) by one large adjustment. This plate overlap technique was introduced by Eichhorn and reviewed by Googe et. al. The author now has developed a set of computer programmes which allows the adjustment of any set of contemporaneous overlapping plates. There is in principle no limit for the number of plates, the number of stars, the number of individual plate constants for each plate, and for the overlapping factor.
