Pore Typing

Pore typing, the first half of the Petrographic Image Analysis (PIA) software system, represents a quantitative way of classifying the overall geometry of a pore system as sampled in a thin section and determining how that system changes either vertically, horizontally or both in a reservoir and among connected reservoirs.  The goal is to sample a great number of pores/porels in a thin section and among a collection of thin sections to determine the major pore types, what the geometry of those pore types express and, finally, how these pore types vary across the study area.  Not only is pore typing important to understand the geology and post-depositional history of a reservoir, it is important to the petroleum engineers and petrophysicists.

The underlying assumption to pore typing (which has held up in our experience) is that the shape of the pores/porels is at least a partial record of the original depositional environment facies, diagenesis and burial history of that sample of rock.  The fact that it is a partial record reflects the fact that the shape of the pores/porels generally reflects the last of a sequence of post-burial events affecting the rock. Being able to produce three dimensional mappable variables are valuable to produce the insights needed to properly engineer a reservoir over time.
