API RP 1115, 2nd Edition, November 2018 - Design and Operation of Solution-mined Salt Caverns Used for Liquid Hydrocarbon Storage

This recommended practice (RP) provides the functional recommendations for salt cavern facilities used for liquid hydrocarbon storage service and covers facility geomechanical assessments, cavern well design and drilling, and solution mining techniques and operations, including monitoring and maintenance practices. This RP is based on the accumulated knowledge and experience of geologists, engineers, and other personnel in the liquid hydrocarbon storage industry and promotes public safety by providing a set of industry accepted design and operation guidelines. This RP recognizes the nature of subsurface geological diversity and stresses the need for in-depth, site-specific geomechanical assessments, with a goal of long-term facility integrity and safety.

This RP includes the cavern well system (wellhead, wellbore, and cavern) from the emergency shutdown (ESD) valve to the cavern and facilities that have a significant impact on the safety and integrity of the cavern system. It also includes a structure for risk assessment for salt cavern facilities used for liquid hydrocarbon storage service.

This RP may be applied to existing facilities at the discretion of the user.

This RP does not apply to caverns used for the storage of gaseous products, natural gas, brine production, or waste disposal, nor to caverns that are mechanically mined, or depleted hydrocarbon or aquifer underground gas storage systems. This RP does not cover facility piping.
