Steam Injection Recovery Services

DESHI started providing steam Huff and Puff services to SHENGLI oilfield since 2002. DESHI is now operating 15 sets of sub-critical steam generators in 3 major oilfields in China. DESHI has been providing reliable and safe services in the past years.

SAGD (Steam Assisted Gravity Drainage) is a thermal production method for heavy oil. It pairs a horizontal injection well with a horizontal production well drilled along a parallel trajectory. The wells are drilled with a vertical separation of approximately 5 meters with the injector above the producer, and with both wells positioned low in the reservoir. Saturated steam is injected into the reservoir via the SAGD injection well where the steam rises and expands throughout the reservoir.
