Appendices for PhD Thesis: "Laboratory insights into reactions between gas shales and hydraulic fracturing fluids at reservoir temperatures and pressures: a global perspective."

Three excel spredsheets contain extended geochemical data produced as part of the PhD research and referenced in the thesis. The data was generated using ICP-MS and ICP-AES at external laboratories.

Appendix A - contains total recoverable element concentrations (TRE sheet) and acid extractable element concentrations (AEE sheet) for approximately 65 elements for all the shale samples used in this study. The element concentrations are reported as an average of duplicates.

Appendix B - contains five sheets as follows with element concentrations reported as an average of duplicates:

Table B1 SHFF: Summary results of leaching tests with synthetic hydraulic fracturing fluid (SHFF) for elements of interest.

Table B2 SGW: Summary results of leaching tests with synthetic groundwater
(SGW) for elements of interest.

Table B3 % SHFF TRE: SHFF leaching results for elements of interest, normalised
to the element content of each sample (TRE) and expressed as a %. Numbers in red are % calculated based on the detection limit.

Table B4 % TRE SGW: SGW leaching results for elements of interest, normalised to
the element content of each sample (TRE) and expressed as a %. Numbers in red are % calculated based on the detection limit.

Table B5 1M HCl: results of the preliminary 1M HCl leaching tests. % TRE represents element concentrations normalised to a given element total recoverable content of each sample. Numbers in red are % calculated based on the detection limit.

Appendix C - a full dataset of the synthetic hydraulic fracturing fluid (SHFF, 54 elements) and synthetic groundwater (SGW, 54 elements) leaching results presented in Chapter 4.4. The element concentrations are reported as an average of duplicates.
