[[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 in estimating richness|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.
