Aquifer Gas-Injection Alternative for Handling Associated Gas Produced From Deepwater Fields

摘要

Deepwater production requires new approaches to field development.Floating production structures provide a method to produce oil and transport it to market.However,handling the associated gas is a new challenge.Storing produced associated gas in an aquifer for recovery at some future time was studied by use of a hypothetical sandstone aquifer in an anticlinal trap.The results indicate that it is technically feasible to recover gas injected into an aquifer,provided the aquifer exhibits the appropriate structure,size,and permeability.
