Calgary-based Pulse Oil Corp. has announced that Pulse and its contracted technical consultants have completed Phase Two of the Bigoray Enhanced Oil Recovery (EOR) Modelling Project. Phase 2 incorporated the geological and petrophysical analysis completed in Phase 1 into a pool architecture and structural model.
The company’s 3-D seismic data base was incorporated into the model, the first time modern 3-D seismic data has been involved in these pool evaluations. This detailed delineation of the pool boundaries has provided a positive alternate interpretation to those evaluations undertaken previously by the Alberta Energy Regulator and by Pulse’s independent resource assessment of the company’s Nisku EOR project in the Bigoray area of Alberta previously announced on January 9, 2018.
Phase 3 has now started and consists of a dynamic model being used to history match existing data and run sensitivity cases simulating various development and solvent injection scenarios. This final Phase 3 work is scheduled for completion before year-end and will ensure Pulse’s team make the best decisions to maximize oil recovery from these well-established Devonian-aged oil reservoirs.
Pulse Oil president and COO, Drew Cadenhead, commented, “We are very happy with the results of our EOR project to date, in particular the Phase 2 structural interpretation of our reservoirs. Our 3-D data sheds far more detailed light on what these two pinnacle reefs look like 2 km under the surface of central Alberta and give us a new positive interpretation on some of the assumptions we have been making from past work.
“This is why we are going through this detailed project before implementing the physical injection scheme of the EOR. Identifying the optimal type of miscible product to use in our injection scheme as well as the optimal location of our production and injection wells will ensure we maximize the recovery factor of the remaining oil in our pools.”
