| SAMPLES | A listing of downhole samples, such as conventional cores and cuttings recovered from the well. The top and bottom are noted for each conventional core, however, only the sample interval and sample frequency are noted for cuttings and sidewall core. The name of the sampled lithostratigraphic unit is noted for each conventional core. |

|---|---|---|
| SAMPLES | LOC_NO | Location number. A three digit number, preceeded by the letter "D" (for Dartmouth) that is used by GSCA and CNSOPB staff as a shorthand means of referring to a well. Each well is assigned a location umber when the well samples arrive at CNSOPB for curation. |
| SAMPLES | AUTHOR | The author (usually an oil company) of the well history report. The operator of the well is usually the author of the well history report. |
| SAMPLES | YEAR | The year in which the well history report was published. If a well has been re-entered and sampling was carried out over two or more drilling seasons and a new well history report was produced to document the re-entry data, then the year component will give the year of the publication of the new well history for samples taken during the re-entry seasons(s). |
| SAMPLES | JOURNAL | The title of the journal (usually the well history report). The primary source of sample data is the well history report, although the detailed sample files kept by CNOPB/CNSOPB are also examined because they list sidewall cores available for examination and study. The well history sidewall core lists are compiled before the sidewall cores are subjected to analysis in Calgary, which often leads to their destruction. |
| SAMPLES | SAMPLE | The type of well sample, such as CUTTINGS, CONVENTIONAL CORE or SIDEWALL CORE. |
| SAMPLES | COMMENTS | Descriptive information on the well sample. In the case of cuttings this component lists the cuttings interval (such as "5 M INTERVAL"), for conventional core this component lists the core recovery (such as "6.3 M RECOVERY"), for sidewall core this component lists the number of sidewall cores available for study. |
| SAMPLES | LOCATIONS | The location where the samples are curated. Such as CNSOPB (Scotian Shelf samples) or CNLOPB (for Grand Banks/Labrador samples). |
| SAMPLES | FORMATION_CORED | The geological formation that the conventional core was taken from. A slash "/" denotes a formation or member boundary within the cored interval (such as "WYANDOT FM/DAWSON CANYON FM"), but this contact may not necessarily appear in the core due to poor or incomplete recovery. A dash "-" denotes an ambiguously defined formation (such as "MICMAC-ABENAKI FM"). The data sources for the numbered source sandstones (such as "SANDSTONE #02") in some or most of the Venture/West Venture/West Olympia/Thebaud wells are the well history reports. "N/A" indicates no recovery on the core. |
| SAMPLES | TOP | Depth in the well, from the rotary table, to the top of the sample interval. |
| SAMPLES | BOTTOM | Depth in the well, from the rotary table, to the bottom of the sample interval. |
| SAMPLES | UNITS | The unit of depth measure, feet or metres. |
| SAMPLES | CORE_ANALY | Does the BASIN database contain core analysis data for this well?) "Y" = yes. |
