|---|---|---|
| MATURITY | LOC_NO | Location number. A three digit number, preceded 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 number when the well samples arrive at COGLA/CNSOPB for curation. |
| MATURITY | AUTHOR | The author (oil company or individual). Author of the document/report from which the maturation data is taken. |
| MATURITY | YEAR | The year in which the document/report was published/produced. |
| MATURITY | JOURNAL | The title of the document/report from which the maturity data is taken. |
| MATURITY | DEGREE | The quantitative measure of maturation, such as 0.34 (vitrinite reflectance). |
| MATURITY | TEST | The technique used to determine maturity, such as vitrinite reflectance. Maturation studies are employed in petroleum geology to detect zones of possible oil/gas production by determining the degree to which organic matter, found dispersed throughout some sedimentary rocks, has been converted, by temperature and time, into petroleum. In BASIN, the technique of maturation determination most often cited is vitrinite reflectance, (VIT), as this analytical technique has been applied to a large number of east coast offshore wells by GSCA staff. Other methods of maturation determination that have been applied to a smaller number of wells are kerogen analysis, thermal alteration index determination- (TAI), and fluorescence studies, (FLUORESCENCE). The following abbreviations are used: VIT (COAL)- vitrinite reflectance measured from coaly matter. VIT (OXIDIZED)- measured degree of vitrinite reflectance is anomalously low, due to oxidation of the samples. VIT (REWORKED)- measured degree of vitrinite reflectance is anomalously high, probably due to reworking of the sample. VIT (MEASURED)- measured vitrinite reflectance value (not corrected for oxidization or reworking). VIT (CALCULATED)- calculated vitrinite reflectance value (corrected for oxidation or reworking). VIT (CORRECTED)-as above. VIT (AVERAGE)- the vitrinite reflectance value presented is the average of a number of readings taken on a single sample. VIT (EDITED)- the vitrinite reflectance value presented is the average of a number of readings that have been edited of anomalous values. VIT (SEE PAPER)- vitrinite reflectance data cannot be adequately summarized for inclusion in BASIN. PRELIMINARY TAI - thermal alteration values not presented becaues they are based on a different numerical scale than all subsequent TAI data. (FLOURESCENCE)- non-quantative fluorescence data (only fluorescence colours given). |
| MATURITY | TOP | Depth in the well, from the rotary table, to the top of the sample from which maturation was determined. |
| MATURITY | BOTTOM | Depth in the well, from the rotary table, to the bottom of the sample from which maturation was determined. |
| MATURITY | UNITS | The units of depth measure, FT or M. |
| MATURITY | VIT_SD | The standard deviation value associated with the vitrinite reflectance reading. |
| MATURITY | CITEID | Citation ID number (Bibliographic reference number). |
