Cold heavy oil production with sand
Cold heavy oil production with sand (CHOPS) is a technique for extracting difficult heavy crude oil where sand is used as a means enhancing the productivity of the oil well. CHOPS is now used as a "quasi primary" production approach in unconsolidated sandstones. By 2002 Energy Alberta claimed that there were already thousands of wells in Canada that were stably producing oil through CHOPS. However, by 2014 there were still no regulations for this widely used heavy oil production method. Serious health concerns regarding the way in which CHOPs was used by Baytex Energy in the Peace River oil sands area creating emissions that forced long-term residents from their homes. Alberta responded by denying Baytex any further drilling permits.
