Summary

This study tests the influence of environmental conditions on conversion of the maceral bituminite to a solid petroleum residuum (solid bitumen) during pyrolysis. The presence of water in sedimentary basins controls multiple processes during petroleum generation, migration, and storage. Four organic-rich (26–36 wt.% total organic carbon) oil shale samples were collected from thin-bedded (several cm thick), discontinuous outcrop exposures in the Neoproterozoic–Lower Cambrian restricted marine Salt Range Formation in the upper Indus Basin, Pakistan. Samples were from the Khewra Gorge (K-2) and Sohan Nala localities [SN-R(c), SN-5(b), SN-1]; a sample of Joadja torbanite coal from Australia containing terrigenous vitrinite was also included [...]

Purpose

The purpose of this study is to describe the response of sedimentary organic matter to heat treatments in different environmental conditions. This work was performed to better understand: i) how water behaves as a H donor during petroleum generation, ii) how brine can influence organic reactions during pyrolysis, and iii) how the presence or absence of water or brine can influence solid bitumen properties during thermal evolution.
