The liquids extraction plant closed in 1927 and reopened in 1933 after the company revamped the facility. The new plant used "lean oil" absorption, a process that forced raw gas into contact with lean oil in chains of steel bubble caps. Improvement of the absorption medium and contact between the gas and the oil made for substantially higher rates of liquids recovery. The new plant was so successful that other companies built two similar plants in Turner Valley, and Royalite built a second plant to handle its production from the south end of the field. Gas and Oil Products Ltd. built a similar plant at Hartell in 1934 and British American (BA) opened one at Longview in 1936.
