Mineralogy, Fracture and Textural Analysis for Formation Evaluation in Tight Gas Reservoirs

Tight gas reservoirs are generally defined as having permeability less than 0.1mD and requiring hydraulic stimulation to<br>produce commercially. Their low permeability is a consequence of a complex diagenetic history where compaction and<br>mineral growth reduces the pore and pore throat sizes. Tight gas sands are also often deeply buried and subject to large<br>stresses.
