Distribution of Porosity Thickness in the Leduc Formation, Swan Hills / Slave Point Formations, and Granite Wash in Alberta (tabular data, tab-delimited)

This dataset includes the porosity-thickness (PHI*H) values derived from wells for three geological units in Alberta: the Leduc Formation, the combined Swan Hills and Slave Point formations, and the Granite Wash.

PHI*H is calculated by multiplying net reservoir thickness (H) by average porosity (PHI) at each well location. H is determined from logs by using petrophysical cutoffs, while PHI is interpreted from logs and calibrated with core data. PHI*H is an estimate of total pore space per unit area at each well location.

The parameter cutoffs used for net reservoir thickness determination for the respective geological units are as follows:
1) Leduc Formation: porosity >=3%
2) combined Swan Hills and Slave Point formations: porosity >=3%
3) Granite Wash: volume of shale <=40% and porosity >=8%
