  1. Apache reports new water release in Alberta

    Apache Canada Ltd. is investigating a second release of produced water at facilities in northern Alberta. An operator on Oct. 25 discovered the new release on a water-injection pipeline at Shekilie oil field, about 50 km northwest of Zama City, while investigating a volume discrepancy. Internal data indicate the release began Oct. 3. Apache estimates volume of the release at 1,800 cu m of produced water and size of the affected area at 5.09 ha. The water contained trace amounts of hydrocarbons. The cause is under investigation. Earlier, Apache reported stress corrosion cracking of a water-injection pipeline as the likely cause of a June release of produced water at its Zama operations, which include an enhanced oil recovery pilot based on injection of carbon dioxide ( OGJ Online, Oct. 22, 2013 ). Neither release endangered the public, Apache said. The company said it is installing real-time monitoring involving supervisory control and data acquisition to its four water-injection systems in the Zama operations area.
