Pulse Oil Corp. has announced the completion of phase one of the Bigoray Enhanced Oil Recovery (EOR) Modelling Project.
The modelling project sets out to create a dynamic reservoir model of Pulse’s two Bigoray Nisk reefs by incorporating all petrophysical log data, petrological core and drill-cutting data, 2D and 3D seismic data, and all historical production and pressure data into a single dynamic model.
The model will then simulate different development solvent injection scenarios, allowing Pulse’s team to make the best decisions to maximize oil recovery from well-established Devonian-aged oil reservoirs.
Phase one included an analysis and interpretation of the logs and petrophysical data associated with every well (15 wells) drilled within Pulse’s two Nisku pools.
This was then followed by an analysis and interpretation of every core cut within the two pools (10 cores).
“Given our two pools have already proven themselves as established oil reservoirs associated with secondary water-flood schemes over their production history to date, we aren’t surprised by the outcomes of phase one of the study,” said Pulse’s president and COO, Drew Cadenhead.
This data is important for phase two, when the petrological and petrophysical data will be incorporated into a pool architecture and structural model is built from Pulse’s 2D and 3D seismic data base.
“What is surprising, and encouraging at the same time, is that pervasive matrix dolomitization has shown the existence of a tri-modal porosity system in these two reservoirs where matrix, vugular, and fracture porosity all play a role in the large amount of discovered petroleum initially in place (PIIP) as we detailed in our January 2018 news release,” Cadenhead continued. “The porosity/permeability cross plots compared favourably with off-setting pools where EOR implementation has resulted in recovery factors as high as 85 per cent of PIIP.”
