[[Depositional environment]] controls the amount of organic carbon contained in a rock. [[Source rock]]s are generally associated with areas where high organic productivity is combined with (1) deposition in poorly oxygenated environments ([[anoxic]] to [[dysaerobic]]), (2) upwelling, and (3) rapid sedimentation,<ref name=ch06r3>Chinn, E., W., 1991, The role of organic geochemistry in petroleum exploration: Basin Research Institute Bulletin, Louisiana State University, Baton Rouge, LA, p. 15–23. ''Short paper that summarizes petroleum geochemistry and its analytical techniques.''</ref> because these processes preserve organic matter.
