User Manual
The Pulsar is a slim pulsed neutron tool for formation evaluation and reservoir monitoring in cased boreholes. The Pulsar Processing provides integrated interpretation of the data logged by this tool. Porosity, Sigma, FNXS, Elemental yields and saturation are computed.
    There are following Worksteps implemented in this plugin.
  • Dataset creation: prepares input dataset for the following modules.
  • GSH Analysis: computes Porosity, Sigma & FNXS
  • Spectral Analysis: computes elemental yields and C/O ratios.
  • Spectral Reconstruct: perform a quality control on the spectral analysis processing.
  • Stacking module: stacks dataset from multiple passes in same well.
  • SW from C/O: computes Sw from carbon/oxygen ratios.
  • Three Phase Holdup: compute the borehole holdup from Pulsar log data.
  • Layout Templates: views results on a graphical layout.
    Following modules are released in this plugin.
