==Dissolved-gas shows==

Dissolved-gas shows are reported as mud-log shows, trip gas, gas-cut fluids, and gas bubbles in samples. Dissolved-gas shows occur when gas is liberated from water as pressure drops in rock cuttings pores as they rise to the surface during drilling. The amount of gas contained in formation water depends on the salinity. Fresher formation water absorbs more gas. Quantities range up to 14 scf/bbl of water.<ref name=ch09r54>Schowalter, T., T., 1979, Mechanics of secondary hydrocarbon [[migration]] and entrapment: AAPG Bulletin, vol. 63, no. 5, p. 723–760.</ref> Dissolved gas has no capacity to flow into a wellbore, and dissolved shows are significant only in that hydrocarbons are present.
