Author's affiliation:  Reservoirs Inc. and Coalinga Corporation
Age: Late Cretaceous
Formation:  Tuscaloosa Formation
Location:  Baywood field, St. Helena Parish, Louisiana, United States
Well:  Keck Clemons No. 1
Depth range:  14540-14600 feet.  
Depositional Environment:  Deltaic channel to point bar environment (best reservoir rocks)
Lithology:  “in terms of composition and diagenesis, the reservoir sandstone is anomalous to most Lower Tuscaloosa sandstones.  The sandstone borders on a quartzarenite (Q=94%, F=0%, RF=6%) and is cemented by a combination of quartz overgrowths (11%), kaolinite clay (6.5%), and dolomite (5.5%).  Most lower Tuscaloosa sandstones in comparison are mineralogically immature with a high lithic fragment content and are cemented by grain-coating chlorite clay.”
Grain size:   fine to very fine grained -- see table of data
Alteration:  see lithology comments above.  “Porosity is comprised of both primary intergranular and leached-grain, secondary pores.  Microporosity is minimal.”
Production:  gas 
Core measurement conditions:  not given.
Data entry:  manual entry from Figure 3 of the referenced paper.
