In June 2011, a sinkhole of super-heated earth opened up and swallowed an oilfield worker in Kern County. That field had been producing heavy oil for decades utilizing a high-pressure production ...

A study has shown that steamflooding distillation effects would improve crude recovery from thin reservoirs with less viscous crude. Steam distillation means that steam injection will cause some ...

Flue gas assisted steam assisted gravity drainage (SAGD) is a frontier technology to enhance oil recovery for heavy oil reservoirs. The carbon dioxide generated from the thermal recovery of heavy oil ...

A new gravity-assisted steam flooding technique helped control steam-channeling problems in the Liaohe heavy-oil area in China. Reservoir fluid-mechanics analysis showed that a large dip angle hinders ...
