The file LAS coverage.pdf graphically depicts the LAS wireline data available for the borehole, and the depths (in metres) over which the data was available for this study. Overlain onto this graph are the formation tops taken from Fraser and Hogue (2007). Log curve abbreviations in this graph are explained in Appendix B.

The ‘Log Plots’ subfolder contains .pdf files named “Log Plot xx-xx m.pdf” which are visual displays of the available wireline log data along with results of the reservoir petrophysical assessment plotted over a specific depth interval of the borehole. The data is presented in a series of seven tracks, with units, value ranges and/or lithology displayed at the top of each track. The acronyms of each log and calculated curve are given in Appendix B.

Track one displays the logs for borehole size (BS), caliper (CALI), gamma ray (GR), and spontaneous potential (SP). It may also show the bulk density correction curve (DRHO).

Track two is the measured depth log and shows reservoir zones (labeled ‘gross’) and pay zones (labeled ‘pay’), highlighted by yellow and red flags, respectively. Track two also displays the bad hole flag (FBH) as blue flags on the left side of the track.

Track three displays a variety of resistivity logs (ILD01; ILM; LL8; SFL; SN; LLD; SN16; and LLS).

Track four displays the sonic logs (DT), neutron logs (NPHI; PHInls), density logs (RHOB, DPHI), the calculated effective porosity curve (PhiE), and the core porosity curve (PhiCor). It may also show the density correction curve (DC).

Track five displays calculated water saturation (Sw) and shale volume (Vsh) curves.

The sixth track is the visual lithology track displaying calculated relative abundance of shale (Vsh), sandstone (Sand), limestone (Lime), dolostone (Dolo), and the effective porosity (PhiE) and bulk water volume (Bvw) curves.

Track seven displays the calculated permeability curve (K*). Ki is the permeability curve calculated from the Wyllie-Rose equation, and Kc is the permeability curve calculated from the ‘Coates’ equation. Ka is a curve merging Ki and Kc where the data spanned both clastic and carbonate formations. Kmax is permeability calculated from core analyses.

The ‘Log Analysis Tables’ subfolder contains Excel spreadsheets named “Log Analysis Table xx-xx m.xls”. These files contain tables of data displaying borehole depths (Depth) with respective calculated values for badhole flag (FBH), effective porosity (PhiE), permeability (Ki, Kc or Ka), volume of shale (Vsh), and water saturation (Sw). In some wells, one or more of these values may be absent due to insufficient log coverage. The interval/step between borehole depths is determined by the interval/step that was in the original .LAS file.
