... Abstract Diagenetic changes (e.g. cementation, compaction) in tight gas sandstones (TGSS) often disconnect the original, inter-granular pore space and further create microporosity within the original grains (e.g. by dissolution) or by filling the inter-granular porosity with clay...

To that end, our work-flow integrates multiple data evaluation techniques and multiple data scales using a core-based rock typing approach that is designed to capture rock properties characteristic of tight gas sands. Fundamental to this process model...

... the analysis of the database, we divided the wells into groups based on the type of formation in which they were completed. Those groups are (1) sandstones, (2) carbonates, (3) coals, and (4) shales. In addition, we felt that it would be beneficial to keep the offshore wells in a separate group; so, we...
