Determination of Residual Oil Saturation to Carbon Dioxide
Why it is important?
• Miscibility developed by multiple contact results in variable amount of oil left behind in CO2-swept zone
• Uncertainty in projection of oil recovery by the simulator
![Page 12: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/12.jpg)
Critical Issues to the Measurements
• Measurement needs to account for
– Well defined development of miscibility
– Representative fluid and rock properties

Current Reservoir Condition
• Average reservoir pressure is around 500 psia, which is not high enough for CO2 miscible displacement
• Reservoir must be pressurized
![Page 19: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/19.jpg)
Approaches
• Construct a generic model to simulate the process of– Primary production– Pressurization
• Model contains– 126 active production wells in a 2 by 2
square miles area (2560 acres)

Satisfactory Match
• Simulation results were to match– Reservoir average pressure– Cumulative oil and water production– Current oil and water production rate
![Page 23: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/23.jpg)
Observations
• Reservoir is a layered reservoir with high permeability contrast between layers
• Bottom water drive
Edge water drive does not provide enough energy to support the average reservoir pressure and production performance

Simulation Tests to Pressurize a Project Area
• 5 spot pattern (10 acres) with 6 confining injectors (within 120 acres)
![Page 26: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/26.jpg)

Pressure Distribution After 3-year’s Pressurization
![Page 28: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/28.jpg)
Summary of Pressurization Process
• The magnitude of pressure increase within a pattern depends on the size of the pattern, confining area, and bottom hole pressure control of injectors and producers.
• The ultimate pressures within the pattern varied from 1200 psia to 1500 psia.
![Page 29: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/29.jpg)
Preliminary Results
• Attainable reservoir pressure might slightly below the MMP as required for a miscible CO2 displacement
• Oil recovery remains relatively high (70 ~85%) for a few hundred psi below MMP
![Page 30: Carbon Dioxide Demonstration Project Supporting Research at KU Jyun-Syung Tsau presented for Tertiary Oil Recovery Project Advisory Board Meeting October.](https://reader036.fdocuments.us/reader036/viewer/2022081602/5518a178550346881f8b48c6/html5/thumbnails/30.jpg)
Current Status
• Oil and gas samples collected from the wellhead and separator were analyzed by Core-Lab
• High nitrogen content was found on some of the separator samples through the quality check, which suggests the needs to measure MMP and oil recovery using a live oil sample
• Detailed PVT test and swelling test would be conducted by Core-Lab, and data would be used for compositional simulation
