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.
Origin & Geology
The Lloydminster area straddles the Alberta–Saskatchewan provincial border, centred on the town of Lloydminster (~300 km east of Edmonton). Oil is produced from the Lower Cretaceous Mannville Group — a sequence of deltaic and fluvial sands subdivided into the Dina, Sparky, Silverdale, and Colony formations. These shallow sands (typically 300–700 m depth) hold 3.34 billion barrels of oil-in-place in the Alberta segment alone, with cumulative production exceeding 176 million barrels as of 2022.
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.
What "Lloydminster-type Crude" Means
"Lloydminster-type" is an industry term covering several related conventional heavy crude streams gathered from fields in the Lloydminster fairway, including:
-
Lloyd Blend (LLB) — the primary pipeline grade, gathered by Husky Midstream (Cenovus) and priced at Hardisty
-
Lloydminster Kerrobert (LKB) — a sub-stream with slightly different quality
-
Federated (FED) — a heavier conventional stream from the same area
-
Midale Blend — southeastern Saskatchewan contribution
-
Imperial Sour Blend — gathered by Imperial Oil from overlapping Mannville formations
These streams are conventional crude (not diluted bitumen/dilbit) — they flow at reservoir temperature without steam or diluent, though CHOPS and SAGD thermal methods are applied to enhance rates.

On CrudeMonitor's September 2025 batch (LLB-1321), the stream showed increased density, sulfur, MCR, and metals vs prior months, with reduced BTEX and C6–C8 light ends — reflecting the variability inherent to multi-pool blending from the Mannville fairway.
Production Methods
Unlike oil sands bitumen which requires either mining or steam-intensive SAGD to mobilize, Lloydminster heavy crude production uses a range of methods:
-
CHOPS (Cold Heavy Oil Production with Sand) — the traditional method exploiting foamy oil drive and high-permeability sands, widely applied historically across the Mannville
-
SAGD (Steam-Assisted Gravity Drainage) — Cenovus operates 12 thermal SAGD assets in the Lloydminster area for tighter/deeper zones
-
EOR (Enhanced Oil Recovery) — polymer and steam flood pilots ongoing
-
Waterflood — applied to maintain reservoir pressure in conventional pools
CHOPS is uniquely suited to the shallow, high-porosity Mannville sands, where wormhole networks formed by sand production create drainage conduits that dramatically improve productivity without steam energy costs.
Infrastructure & Refining Hub
Lloydminster is uniquely positioned at the border of two provinces and hosts its own dedicated heavy oil processing infrastructure:
This co-location of production, upgrading, and refining in the Lloydminster area makes it a uniquely integrated heavy oil hub — unlike most Alberta heavy streams that must travel hundreds of kilometres to a refinery.
Refinery Requirements
Lloydminster-type crude is categorized as heavy sour and requires high complexity processing:
The dominant end-products are asphalt, ULSD, gasoline, and petroleum coke depending on the refinery configuration.
Lloydminster vs. WCS
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.
