Abstract

Shale gas has become one of the key points for the development of unconventional oil and gas. To better understand the influence factors of TOC in shale from Montney formation, total organic carbon (TOC), Rock-Eval analysis and saturation measurements were conducted to quantitatively analyze the influence factors of TOC. The results show that the kerogen type in the study block is gas-prone. Porosity and permeability have good correlations with TOC for high-maturity samples, demonstrating that organic pores are well developed in studied shale. The relationship between TOC and Tmax is not obvious in low maturity samples, whereas the relationship between TOC and Tmax show a negative correlation for the samples with high maturity. Organic matter begins to transform into hydrocarbon before Tmax reaches a certain level. Gas saturation increases with the rise of TOC. Bulk density decreases with the increase of TOC. In general, TOC has a great influence on the pore structure of shale and the hydrocarbon-generating transformation of kerogen and could well characterize the gas content and thermal evolution of the reservoir.
