Visual kerogen estimates are usually presented in terms of the percentage of each type of kerogen in a sample derived from cuttings composites or core (conventional or sidewall). For example, a visual estimate of kerogen type might be stated as 50% woody, 45% amorphous, 5% inertinite. In general, the more amorphous kerogen present, the more oil prone the rock is. | Visual kerogen estimates are usually presented in terms of the percentage of each type of kerogen in a sample derived from cuttings composites or core (conventional or sidewall).
