Data for: Natural mineralized fractures from the Montney-Doig Formations (Western Canada Sedimentary Basin): controlling factors and implications for unconventional exploration
Description
Table S1a. Details on investigated samples from well core 16-17, including sample name, depth, sequence of provenance, depositional environment, number of fractures, their orientation and kinematic aperture, texture of the sealing calcites and their O-C-Sr isotope composition. In some samples, O-C isotope analysis were performed for different veins or for different calcite textures occurring in the same vein. Table S1b. Same as in Table S1a for the samples from well core 12-36. Table S2a. Details on samples from well core 16-17, including sample name, depth, sequence of provenance, depositional environment and the parameters obtained from Rock-Eval analysis accomplished with the Shale Play Method® developed at IFP Energies nouvelles (Pillot et al., 2014; Romero-Sarmiento et al., 2016a, 2016b): Sh0, Sh1, Sh2, Tmax, TOC, HI, OI, HCcont, MinC. TOC= total organic carbon, HI= hydrogen index, OI= oxygen index, HCcont= content in hydrocarbons, MinC= mineral carbon. Column names with –B and –E refer to analyses performed on bulk-rock and extracted organic matter, respectively. Table S2b. Same as in Table S2a for the samples from well core 12-36. Table S3a. Spreadsheet for well core 16-17 with the evolution of different properties with depth used for frequency distribution analysis with EasytraceTM software. The properties considered are: presence/absence of fractures (i.e. FRACTURE), the stratigraphic sequence (i.e. SEQUENCE), the depositional environment (i.e. ENVIRONMENT), the TOC values (i.e. TOC). Each line of the table represents a point virtually sampled along the log of well 16-17 to which information on the different properties were attributed via numerical codes (see Table 1). As requested by the software, the value “777” was attributed to the cells where information for a given property was not available. Table S3b. Same as in Table S3a for well core 12-36.
