Source rock richness is determined by measuring the total organic carbon (TOC) present in a rock. The two most common techniques of analyzing a rock for TOC are Rock-Eval pyrolysis with TOC and the LECO method. Conventional well logs can also provide information for evaluating interval richness. | Source rock richness is determined by measuring the total organic carbon (TOC) present in a rock.
