12. Well Model Calibration with DIAL Data
Using the last available data from the DIAL System as a pressure gradient survey, update the WinGlue model to predict downhole conditions and production rates.
Using data from the DIAL System to update model to enable production optimization.

13. Calibrated DIAL Well Model
Using the last available data from the DIAL System as a pressure gradient survey, update the WinGlue model to predict downhole conditions and production rates.
The primary point of injection is DIAL unit No. 3.
Due to a high casing pressure (1200psig) multipoint injection is evident.
The upper IPO valve is open and injecting a proportion of the surface casing gas.

14. Comparing Against Operator Expectations
Using the last available data from the DIAL System as a pressure gradient survey, update the WinGlue model to predict downhole conditions and production rates.
Table of Uplift Estimated by Operator
The operator estimated uplift based on their own modelling was 26%.
Summary of Actual Uplift
The well model enabled us to compare performance against a conventional IPO system.
Modelling based on actual data demonstrate uplift of 29%.
This uplift can be attributed to:
Minimized multi-point injection.
Deeper max. lift depth.
Increased drawdown from the reservoir.

15. Permian Program Conclusions
Using the last available data from the DIAL System as a pressure gradient survey, update the WinGlue model to predict downhole conditions and production rates.
Installation proven & lessons applied.
DIAL data matched to well model.
KPI’s exceeded.
Production enhancement over IPO estimated to be 29%.
Planned enhancements:
All DIAL unit installations.
Visualization.
Live streamed unload.
Gas lift automation.
