Heavy Oil Exploration
As the heavy oil industry continues to gain momentum, Orion 3D’s high-resolution DCIP & MT (magnetotelluric) images of the subsurface maximise oil recovery and reduce steam requirements. By measuring the resistivity difference between water, bitumen and rock, Quantec can pinpoint the location of bitumen versus water. Orion 3D collects more data than any other geophysical survey in the world improving image detail and making Quantec’s inversions more precise. Plus, by integrating with all data sets Quantec creates comprehensive models, thereby increasing confidence in reservoir management for petroleum clients.
Why Does Seismic Struggle To Establish Heavy Oil Drill Targeting?
The difference between oil density and water density after SAGD injection is too close to get an accurate reading from seismic, which can only measure density difference. Instead, with the greatest accuracy in the industry, Quantec isolates oil from water with resistivity measurements (using magnetotelluric methods) helping you:
- Determine the underlying water strata to detail the interface between the water/bitumen mixtures.
- Identify thief zones so you can see which obstacles are preventing SAGD from working more efficiently.
- Track the bitumen interface over time through 4D differencing models to identify changes within the reservoir and maximise recovery percentage.
