Need: While the expansion of the gas market does and will continue to foster the search for new gas reserves in areas of acute need, development of new ideas, new techniques and new concepts for gas storage must be explored if the industry is to meet the long range requirements of the expanding gas market.
Result: Storage of natural gas in subsurface but nonporous media has recently been suggested. Storage in dissolved salt caverns, in mined or natural caverns, in underground cavities induced by nuclear explosions and underwater storage have all been subject to studies in order to evaluate their engineering possibility and economic feasibility. Analysis and evaluation of all these new concepts for potential use in gas storage is the object of this three year research program.
Benefit: In reporting the final results the presentation of various topics have been organized as independent sections in a sequence approximately ranging from current and conventional interest to future, completely novel and unconventional aspects. The concept of over-pressuring, its advantages and limitations are discussed in reasonable detail. The complete mathematical formulation of leak problems as two-phase two-dimensional unsteady state flow across cap rocks is entertained. Equations which reconcile the material balances in gas inventory in the storage bubble with the movement of water in and out of the gas sand with leakage occurring across the cap rocks are given in detail. Presentation of work currently underway on evaluation of grouts and reservoir engineering calculations related to grout injection. The storage of natural gas in subsurface, non-porous storage cavities, unconventional methods and new concepts such as storage in cavities resulting from underground nuclear explosions and deep underwater storage near the bottom of oceans are featured.
