Lloydminster-type crude (also marketed as Lloyd Blend / LLB) is a conventional heavy, high-sour crude produced at the Alberta–Saskatchewan border region, distinct from oil sands bitumen in its production method and molecular character, yet comparable in API gravity and processing demands. It is one of Canada's longest-produced heavy streams, with field history dating back to 1926.

The Lloydminster field was discovered in 1939 and has been operated by various majors over time — Cenovus Energy is today the dominant operator via 12 thermal SAGD-based assets plus legacy cold-production wells.

While Lloyd Blend and WCS appear nearly identical on basic quality metrics (API, sulfur), Lloydminster-type crude is a single-source conventional stream with no condensate diluent added, whereas WCS is a formulated multi-component blend — a distinction that matters for refinery unit feed consistency and downstream processing predictability.
