The National Petroleum Council, the Energy Information Agency and other organizations have completed recent studies that predict a need for an increase in storage capacity - particularly for flexible (short term) storage services, Worldwide. Improved technology can make fulfilling this need less expensive for operators and consumers alike. In addition regulatory scrutiny on all phases of the energy industry, in all major worldwide energy consuming nations, have made operational integrity increasingly important and has increased the costs associated with maintaining the integrity.

The Salt Cavern Gas Storage Toolbox (SCGS Toolbox) was prepared to meet worldwide industry needs as follows:

• The need to develop additional capacity at the lowest possible cost.
• The need to increase the flexibility of storage services available to meet market demands for short-term services.
• The need to maintain and improve system reliability and safety. This includes examining the effects of projected increases of non-traditional supplies (including LNG) on storage operations.
• The need to manage costs to protect customers and improve competitiveness
• The need to respond to increased regulatory pressures - ensuring that new regulations are based on sound science.

What is the Salt Cavern Gas Storage Toolbox (SCGS Toolbox)?

The Salt Cavern Gas Storage Toolbox (SCGS Toolbox) is a suite of applications (software and electronic documents) used to meet the technical and economic needs of the gas industry, specifically in the area of Salt Cavern Gas Storage. Salt caverns are becoming increasingly popular as storage vessels for large volumes of high-deliverability compressed natural gas.

What does it contain?

The Salt Cavern Gas Storage Toolbox (SCGS Toolbox) contains a state-of-the-art mathematical simulator (Salt Cavern Thermal Simulator Edition 2.0) as well as five (5) engineering design and operational integrity reports:

• Design Guidelines for Mined Cavern Storage of Natural Gas
• Studies Relative to the Design of Salt Cavern of Natural Gas
• Geomechanical Analysis of Pressure Limits for Thin Bedded Salt Cavern
• Inventory - Migration - Deliverability in Underground Storage
• Technology Enhancements for Inventory Assessment and Integrity Testing

Who would use it and why?

• Design & Engineering - Example; pre-feasibility studies, alternative detailed design simulations calculating transient wellhead pressures and temperatures, etc.
• Gas Marketing & Operations - Example; Feasibility calculations for meeting potential gas nominations, hydrate formation restrictions, etc.
• Finance & Accounting - Example; Inventory verification, true deliverability and remaining unrecoverable calculations, etc.

Benefits to the user:

• Calculation of transient wellhead pressures and temperatures
• Calculation of cavern pressures and temperatures
• Feasibility calculations for meeting potential gas nominations
• Evaluation of hydrate formation potential for possible gas nominations
• Inventory verification
• Calculation of compressor needs for meeting gas nominations
• Calculation of gas velocities.
• Much, much, more.

And most important to industry and operators; Reduced cost for increased gas storage capacity - The SCTS model has been demonstrated to allow lowering of gas pressures, increasing existing working capacities up to 20% with zero increase in cavern size. The key to optimizing salt cavern performance is to determine the minimum allowable gas pressure that will limit microfractures from coalescing and growing uncontrollably.

What is the price and what are the terms of use?

The Salt Cavern Gas Storage Toolbox (SCGS Toolbox) is sold as a single-user license for US$9,995 and includes the first year annual maintenance and support.
