WebBackground gas levels (minimal gas in claystone/shale ) generally increase from ambient values when drilling into under-compacted shales.; Gas shows (from the pores of gas-containing reservoir rock being drilled) will be apparent when a hydrocarbon reservoir is entered.The show’s degree depends on the rock’s pore pressure. Excessive gas shows … Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers (laminae) less than one centimeter in thickness. This property is called fissility.
