2.71 g/cc Limestone Density Matrix used to calculate porosity.
Sonic porosity calculated using (47.5usec/ft) Limestone scale.
Tight pulls, washouts, and borehole rugosity will affect data quality.
All intervals logged and scaled per customer's request.
Annular volume with 4.5 inch production casing from TD to 3700= 266 cu. ft.
Total hole volume from TD to surface casing= 1958 cu. ft.
