DJ Basin Niobrara SuperEORTM

 

The graph below compares the recovery of oil from five stages of a selected DJ Basin Niobrara horizontal well with unoptimized SuperEORTM cyclic injection, versus primary (pressure depletion) production.

While the SuperEORTM process does require accurate compositional reservoir simulation modeling to design, implement and operate a shale oil EOR project, it is simpler to design, install, operate and adjust than natural gas or CO2 huff and puff EOR. 

SuperEORTM process injection periods are short, providing less chance of the injectant moving away from the well and to an offset well, or out of zone. Adjacent wells in pressure communication may be operated efficiently with our process. The compositional model video below depicts the change in reservoir shale oil saturation during the SuperEORTM process, illustrating that oil recovery is predominantly from the inter-stage areas.
