- •
TD-GC analysis can provide chemical fingerprinting of Rock-Eval S1 peaks.
- •
Rock-Eval S1 peaks may overestimate hydrocarbon resources due to mud contamination.
- •
S1 peaks may also underestimate resources potential due to evaporative loss.
- •
High TOC in shale is favorable to hydrocarbon retention but can lower production efficiency.
