1. Scope and Applicability
This PCR defines foreground production records for crude petroleum recovered from reservoirs or bituminous minerals, ending at a declared crude-production gate before manufacture of refined fuels. Oil-sand recovery and oil-shale retorting are distinct conditional routes; synthetic crude upgrading is included when necessary to reach the declared crude feedstock state. It is not a fuel-combustion functional comparison. Declare the route and country, rather than pooling technologies into an assumed representative yield. Sources: un-cpc-3-structure, ifc-onshore-oil-gas-2007, nrcan-oil-sands-processing, epa-spent-oil-shale.

4. Measurement and Unit Rules
| rule_id | Applies to | Required property | Required unit | Rule |
|---|---|---|---|---|
| reference_mass | reference product | Mass | kg | Use net crude mass at the gate, excluding free water, sediment, exported gas and added diluent. Measure using cp_crude_dispatch. |
| volume_conversion | reference product | Mass | kg | Convert metered crude volume to mass using measured density at the same temperature and water/sediment corrections; retain the original volume, temperature and density evidence. Do not assume a universal barrel-to-kg factor. |
| gas_state | fuel_gas; natural_gas_coproduct | Volume | m3 | Retain gas composition, pressure, temperature and dry/wet convention; distinguish metered from standard volume. No assumed density or calorific value. |
| electric_energy | electricity | Net calorific value | MJ | Convert electricity records using 1 kWh = 3.6 MJ; this is a unit identity, not a fuel heating value. |
5. System Boundary
Boundary Abstraction
| Field | Value |
|---|---|
| declared_starting_condition | Reservoir oil in ground, or purchased mined oil-sand/oil-shale feedstock at receiving gate; distinguish these alternatives |
| starting_condition_role | Physical foreground inlet; never an assumption of zero upstream burden |
| product_classification_scope | Crude oils before refining; minerals and co-produced gas are separate inputs or outputs |
| recursive_input_rule | Purchased crude input carries a compatible upstream dataset; internal crude transfers are reconciled without adding a second external input or output |
| upstream_dataset_requirement | Link electricity, fuels, water, hydrogen and mined feedstocks to compatible supply datasets. If mining or drilling is outside foreground, attach its disclosed upstream burden; no silent zero-burden inlet |
| disclosure | Foreground versus background mining and well development; gate, water handling, flaring, upgrading, capital infrastructure and abandonment boundary |
| rule_id | applies_to | Rule | source_ids |
|---|---|---|---|
| boundary_operations | foreground | Include recovery, gathering, separation, conditioning, in-boundary storage, direct combustion, flaring and fugitive losses up to the declared gate; offshore operations require site evidence rather than treating onshore guidance as offshore measurements. | ifc-onshore-oil-gas-2007 |
| boundary_routes | bituminous_minerals | Include the selected mining/recovery or retorting route and upgrading needed for the specified crude state; separately identify internally reused water, gas and heat. | nrcan-oil-sands-processing; epa-spent-oil-shale |
| boundary_completeness | foreground | The cards are a collection core, not an exhaustive list for every field. Add one atomic row for each actual chemical formulation, diluent, drilling input, land occupation, waste and speciated discharge absent from the core. Retain evidence for absence; disclose capital and abandonment burdens via linked datasets or separate records. Exclude post-gate transport, refining and final combustion from foreground. | ifc-onshore-oil-gas-2007 |
6. Process Inventory Structure
Process Map
| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
|---|---|---|---|---|---|
| recovery | Reservoir or bituminous-mineral recovery | required | Declared reservoir extraction, mined feedstock recovery or retorting route | foreground collection block | per 1 kg reference flow |
| conditioning | Separation and residue handling | required | Crude separation and treatment before dispatch | foreground collection block | per 1 kg reference flow |
| upgrading | Crude-feedstock upgrading | conditional | Synthetic crude requires hydrogen addition or carbon removal before the declared gate | foreground collection block | per 1 kg reference flow |
| development | Well development | conditional | Well drilling is inside the declared foreground boundary | foreground collection block | per 1 kg reference flow |
| dispatch | Production-gate storage and dispatch | required | Net crude measurement at the declared gate | foreground collection block | per 1 kg reference flow |
Process blocks partition one aggregate foreground system. Do not count internal transfers as external exchanges. Utility and direct-emission cards in recovery collect the system-wide totals once, with submetered attribution retained by operation. Each conditional card is included only when its stated physical exchange occurs.

7. Allocation and Co-product Handling
| rule_id | applies_to | Rule | source_ids |
|---|---|---|---|
| allocation_subdivide | shared_operations | Use cp_allocation to separate directly metered crude-only, gas-only and shared operations before assigning shared burdens. Keep crude, gas and recovered products distinct; returned gas and water are internal flows. | |
| allocation_causal | shared_burdens | Use documented process-specific causal relationships from cp_allocation. If no defensible physical relationship exists, use declared period revenue shares with actual product quantities and prices, and report a physical-allocation sensitivity. Do not assume one universal energy or mass fraction; no displacement credit for flaring or disposal. | |
| allocation_losses | losses | Assign losses and treatment burdens to the operation that caused them, using the same declared allocation method as its products. Compare pre-allocation total balances and retain the unallocated inventory. |

Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| period_normalization | all inventory rows | Divide period net exchange amount by same-period net crude output mass; assign shared burdens using cp_allocation first; reference output is 1 kg | exchange collection protocols; cp_crude_dispatch; cp_allocation | exchange per 1 kg reference flow | |
| gas_balance | natural_gas_coproduct; methane | Reconcile recovered gas with export, internal fuel use, reinjection, venting and flaring; calculate species emissions only from measured composition and combustion efficiency, not total gas volume | gas meters, composition and fate records | species emissions and gas balance | ifc-onshore-oil-gas-2007 |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| dq_identity | reference product | Confirm declared crude state, route and all required qualifiers; mineral feedstock or refined fuel cannot be the reference product | product tests and gate records |
| dq_completeness | foreground | Reconcile every actual exchange against the site process diagram; disclose estimates, uncertainty and recollection needs; missing data is not zero | site balances, procurement, transfers and emissions |
| dq_range | important flows | Use inferred empirical ranges only with at least two independent original-text-verified sources compatible in boundary and state; no external empirical range is prescribed here | foreground records and source applicability analysis |
9. Validation Rules
| rule_id | applies_to | Rule | source_ids |
|---|---|---|---|
| validate_reference | crude_dispatch | Confirm reference output is 1 kg net crude and every row and collection aggregation uses the same gate, period and net-mass denominator | |
| validate_balance | foreground | Reconcile pre-allocation oil, gas, water and solids balances; disclose stock changes and measurement uncertainty; output mass must not duplicate assumed resource extraction | |
| validate_emissions | direct_emissions | Reconcile combustion, flaring, venting and fugitive sources separately; species, mass units and air compartments must agree; NOx cannot be substituted by N2O | ifc-onshore-oil-gas-2007 |
| validate_uuid | inventory | Check public flow identity, state, type, property and units for each row; unresolved identity remains a named exchange and cannot receive an unverified proxy UUID |

System boundary rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
boundary_operations | foreground | Include recovery, gathering, separation, conditioning, in-boundary storage, direct combustion, flaring and fugitive losses up to the declared gate; offshore operations require site evidence rather than treating onshore guidance as offshore measurements. | ifc-onshore-oil-gas-2007 |
boundary_routes | bituminous_minerals | Include the selected mining/recovery or retorting route and upgrading needed for the specified crude state; separately identify internally reused water, gas and heat. | nrcan-oil-sands-processing, epa-spent-oil-shale |
boundary_completeness | foreground | The cards are a collection core, not an exhaustive list for every field. Add one atomic row for each actual chemical formulation, diluent, drilling input, land occupation, waste and speciated discharge absent from the core. Retain evidence for absence; disclose capital and abandonment burdens via linked datasets or separate records. Exclude post-gate transport, refining and final combustion from foreground. | ifc-onshore-oil-gas-2007 |
Allocation rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_subdivide | shared_operations | Use cp_allocation to separate directly metered crude-only, gas-only and shared operations before assigning shared burdens. Keep crude, gas and recovered products distinct; returned gas and water are internal flows. | |
allocation_causal | shared_burdens | Use documented process-specific causal relationships from cp_allocation. If no defensible physical relationship exists, use declared period revenue shares with actual product quantities and prices, and report a physical-allocation sensitivity. Do not assume one universal energy or mass fraction; no displacement credit for flaring or disposal. | |
allocation_losses | losses | Assign losses and treatment burdens to the operation that caused them, using the same declared allocation method as its products. Compare pre-allocation total balances and retain the unallocated inventory. |
