Humbly Grove Energy Ltd, a wholly owned subsidiary of Petronas, operates the Humbly Grove Oilfield and Gas Storage facility near Lasham in Hampshire. The gas storage facility has to respond to the business requirements of commodity trading and thus has to be in a state of readiness at all times to either import gas from the national grid or export from the store to the grid. The company recently upgraded its control and monitoring systems to ensure reliability and availability, the work was undertaken by Cougar Automation, based locally at Waterlooville, using the latest version of Wonderware InTouch provided by SolutionsPT.
Humbly Grove Energy is situated in the Weald Basin which is a major geological feature of southern England and northern France. Their operations are disposed across the region with an oil production and gathering plant at Weston Common, satellite well sites, interconnecting pipelines for the transfer of gas, oil and water, an oil pipeline to a rail terminal at Holybourne and a gas pipeline to Barton Stacey for gas import and export. The 10 billion cubic feet underground gas storage facility at Humbly Grove was built as an extension to an existing on-shore oil production plant. The store operates by taking natural gas from the National Grid Gas Transmission System through a 27 km long, 24-inch diameter pipeline to the Humbly Grove oilfield. The gas is then pumped for storage into depleted oil reservoirs.
