A geological reappraisal of the Preesall Saltfield, Lancashire, United Kingdom : recognizing geological factors relevant to gas storage

摘要

Bedded salts are characteristic of halite developed in onshore UK, and are hosts or proposed hostsudfor underground gas storage sites in Cheshire, Dorset, Lancashire and Yorkshire. Geologicaludassessments of proposed storage sites provide information that influences aspects of the planning,uddesign and construction of facilities, including cavern and infrastructure placement and operationaludparameters. The Preesall Saltfield is located near Blackpool in north-west England and has been anudarea of interest for the underground storage of gas in solution mined caverns in thick bedded halite forudover a decade. Interest in this area continues, driven by UK Government’s need for additional gasudstorage in a bid to stabilize supply as the UK makes a transition to become a net importer of naturaludgas.
