Source-derived summary

The Spirit River Formation is a stratigraphic unit of middle Albian age in the Western Canadian Sedimentary Basin.

It takes the name from the Spirit River, and was first described in Imperial Oil Spirit River No. 1 well by Badgley in 1952.

Lithology

The Spirit River Formation consists, from bottom to top of fine to medium grained argillaceous sandstone, dark shale, ironstone, greywacke, shale, siltstone, coal and dark shale with thin sandstone and siltstone stringers.

Hydrocarbon production

Gas is produced from channels developed in the Falher Member in northern Alberta.

Hydraulic fracturing in Canada

'Massive' hydraulic fracturing has been widely used in Alberta since the late 1970s to recover gas from low-permeability sandstones of the Spirit River Formation. Massive hydraulic fracturing has been widely used in Alberta since the late 1970s. The method is currently used in development of the Cardium, Duvernay, Montney and Viking formations in Alberta, Bakken formation in Saskatchewan, Montney and Horn River formations in British Columbia.

Distribution

The Spirit River Formation reaches a maximum thickness of 348 metres (1,140 ft). It is found in the sub-surface in the Peace River Country, in an area stretching from Fort St.

Editorial summary

Begin with the source’s own compact description: “Spirit River Formation” is geological unit of the Western Canadian Sedimentary Basin. The dossier treats that line as a proposition to test through Spirit, River and Formation, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1952—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Spirit, River and Formation is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “geological unit of the Western Canadian Sedimentary Basin” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q7577912. Authority coordinates are 55.775, -118.906. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1952.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
