Description
Note: model still runs, it just produces higher emissions than reasonable
Description
Runs with high production using defaults for number of wells and well diameter can produce high emissions driven by excessive CO₂ combustion emissions. The issue is likely caused by large liquid volumes being pumped through an insufficient number of wells, resulting in extremely high calculated duties and combustion emissions for processes like water injection and downhole pumping.
This issue occurs primarily in high-production fields where well count defaults to a low value, leading to exaggerated energy requirements for pumps.
Solution
To address this, the user cannot use the default well counts for injection and production for fields with high production (exact cutoff unknown but definitely causes issues above 500 KBD with the defaults of 24 producing wells, 20 injection wells, 2.78" production tubing diameter). Where well counts (producing and injecting) are not explicitly provided, we are now calculating them using a 1,200 bbl oil/day per well limit as a quick fix. This could underestimate emissions since high producing and injectivity wells can likely flow over that volume. There is a need to continue develop a more robust long-term well count smart default strategy.
