BS EN 1918-1 covers the functional recommendations for design, construction, testing, commissioning, operation, maintenance and abandonment of underground gas storage (UGS) facilities in aquifers up to and including the wellhead.
BS EN 1918-1 specifies practices, which are safe and environmentally acceptable.
In this context, "gas" is any hydrocarbon fuel:
BS EN 1918-1 specifies common basic principles for underground gas storage facilities.
Note 1: Users of this European Standard should be aware that more detailed standards and/or codes of practice exist. A non-exhaustive list of relevant standards can be found in Annex A.
Note 2: For necessary surface facilities for underground gas storage, EN 1918-5 applies.
BS EN 1918-1 on Underground gas storage - Functional recommendations for storage in aquifers is useful for:
The primary function of UGS is to ensure that supply is adjusted for peak and seasonal demand. Apart from this, the storage facilities can provide stand-by reserves in case of interruption of the planned supply. Increasingly UGS is applied for commercial storage services.
Thus, in summary, underground gas storage facilities can be used for:
Storage of gas in aquifers is a proven technology and is mainly used for the storage of large gas volumes. UGS in aquifers (see Figure 2), in which gas reservoirs are built up artificially in originally water bearing structures, require an extended exploration phase in order to prove its ability for the storage of gas.
BS EN 1918-1 provides guidance on design, construction, operation and maintenance of the facility to ensure safety and reliability.
Storage of gas in oil and gas fields in accordance with BS EN 1918-2 will help you ensure:
BS EN 1918-1 supersedes EN 1918-1:1998. BS EN 1918-1 includes some technical changes with respect to EN 1918-1:1998. These include:
