crude oil
liquid oilGeneric crude oil, modeled on IPCC 2006 global defaults (rulebook C.3). No DESNZ entry. Density deliberately omitted (not available in a serious primary source in the v0.1 research pass) so volume↔mass shows 'not available' rather than an invented number.
Typical ranges: Physical crude density varies by grade (~800–950 kg/m³, light vs heavy); a serious primary density was NOT FOUND in this pass, so density is omitted. Energy per physical barrel is an estimate (~5.6–6.3 GJ) and is NOT the same as 'boe' (fixed 5.8 MMBTU convention).
- Crude oil is not a single substance: density and energy content vary by grade (API gravity). Any barrel↔energy or volume↔mass figure for crude is an ESTIMATE, not a measured property of a specific oil.
- A physical barrel of crude is NOT the same as 'boe' (barrel of oil equivalent), which is a fixed 5.8 MMBTU energy-equivalence convention.
