This is a well log used in the oil and gas industry. The acronym PXND_HILT can be found in any (ASCII) log files provided by the logging company. The full name for this log used in the industry is 'Crossplot Porosity from HILT Lithology Computation'. This log is very common in the industry.

The values of this log represent the ratio of the volumes occupied by two components, or by one component to the total volume of the system.

This log usually has the unit 'Porosity'. This is the pore volume per unit gross volume. Porosity is determined from measurements on cores or interpreted from logs.

Data from this log can be used to investigate the porosity of the formation. Similar logs are listed below:

• Neutron Borehole Invariant Porosity, Upper Half (BNPU)
• Density - Magnetic Resonance Porosity (DMRP)
• Neutron Porosity Sandstone, Borehole Corrected, Memory (NPSM)
• APS High Resolution Near/Far Corrected Dolomite Porosity (HFMC)
• Neutron Porosity Base, Transmitted (NPBX)
• MRIL total porosity (MPHS)
• Smoothed Near Detector ONLY Porosity (Sandstone Matrix-Fixed Hole Size) (SNSF)
• APS Near/Far Porosity Standoff Correction (FSOC)
• APS Total Correction Applied to APLC (PHICOR_APLC)
• Density Porosity, Sandstone (DPHS)
