ID4.Q Questions
ID4.F Frequently Asked Questions
Modeling of natural gas reservoirs converted to storarge operations by traditional techniques is often difficult because of the lack of information on the geometry of the aquifer underlying the gas-bearing rock and on its dynamics. Identification techniques have been applied by Agip Mineraria (Italy) to obtain models whose accuracy extended to more than 24 months and could thus be effectively used in developing optimal storage/injection policies.
