SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Estimating field-life greenhouse gas emissions and carbon intensity early in a concept study usually requires detailed combustion modelling or certified emission factors that are not yet available. This Skill provides a transparent, dependency-free screening roll-up that converts year-by-year energy use into annual and total CO2e, a carbon intensity in kg CO2e per boe, and an optional CO2-tax cost. ## Core Features & Use Cases - Field-Life Emissions Roll-Up: Converts annual energy use (MWh) and a public emission factor into per-year and total CO2-equivalent tonnes. - Carbon Intensity & Warning Levels: Computes kg CO2e per barrel of oil equivalent and classifies the result as ok, watch, high, or no-production against a configurable threshold. - CO2-Tax Cost Estimate: Applies an optional carbon tax to produce annual and total emission costs in million USD. - Use Case: An engineer screening a field concept supplies five years of energy use and production forecasts, then receives total CO2e, carbon intensity, and tax exposure to feed an asset-value comparison before committing to detailed NeqSim combustion modelling. ## Quick Start Ask the agent to estimate field-life CO2e emissions, carbon intensity, and CO2-tax cost from a list of annual energy use in MWh, an emission factor, and annual production in boe.

FAQPage Schema
How do I estimate field-life CO2 emissions from annual energy use?

Multiply each year's energy use in MWh by a public emission factor in kg CO2e per MWh and divide by 1000 to get tonnes per year. The EnergyEmissionsModel evaluate method performs this roll-up and returns annual and total CO2e, carbon intensity, and optional tax cost.

How is carbon intensity per barrel of oil equivalent calculated?

Carbon intensity equals total CO2e in kilograms divided by total production in boe. The model returns None and a no-production warning when total production is zero, and classifies results as ok, watch, or high against a configurable threshold defaulting to 17 kg CO2e per boe.

Does this screening model require NeqSim or other Python packages?

No, the model is dependency-free and runs on the Python standard library alone. It optionally detects whether the neqsim package is importable and reports that flag, but NeqSim is only needed for the validated combustion path, not for the screening calculation.

Can I use this screening output for official emission reporting?

No, the output is an educational placeholder using a single public average emission factor with no combustion efficiency, methane slip, flaring, or capture credit. Any reporting or quantitative design use must be escalated to validated NeqSim combustion modelling and certified emission factors.

Why does the carbon intensity result come back as None?

Carbon intensity is undefined when total production is zero, so the model returns None and sets the intensity warning to no-production. Provide a positive flat value or per-year sequence for annual_production_boe to obtain a numeric intensity.
