The fundamental objective of the project is to demonstrate the application and economic feasibility of ?new and novel? fracturing technologies for restoring the deliverability of existing underground gas storage wells. Within this primary objective, several tactical objectives are as follows: - Identify ?new and novel? fracture stimulation methods that hold potential for gas storage wells. -Demonstrate their application, including treatment design, implementation and results. -Evaluate their economic performance as compared to ?typical? (non-fracturing) stimulation practices of gas storage operators, such as blowing/washing or mechanical cleaning of the wellbore, reperforating, water/solvent washes, and acidizing.
