Abstract

The objective of this work was to determine the amount, type and thermal evolution of organic matter in sections of Irati Formation thermally affected by igneous intrusions. Organic petrographic analyse, Total Organic Carbon and Rock-Eval pyrolysis data showed a suitable amount and type of organic matter for oil generation. The biomarker data indicated a low degree of thermal evolution for the extract sampled in the wet gas/dry gas zone, suggesting the presence of migrated hydrocarbons. It was noted that the thickness of the section affected by igneous intrusions depends on the temperature of the igneous body, depth of intrusion and thermal conductivity, which could explain the differences between maturation logs.
