To assess kerogen quality visually, we can separate it from the mineral matrix through acidification. We can then examine the kerogen using transmitted light through a microscope to determine its form (structured or amorphous) and origin. Structured kerogens include woody, herbaceous, vitrinite, and inertinite. Amorphous kerogens are by far the most prevalent and include most of the algal material.

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.
