The '''Ellerslie Member''' is a [[stratigraphic unit]] of [[Early Cretaceous]] [[Geochronology|age]] in the [[Western Canadian Sedimentary Basin]].

It takes the name from [[Ellerslie, Edmonton|Ellerslie]], a community in southern [[Edmonton]], and was first described in [[Imperial Oil]]'s ''Whitemud No. 3 well'' by C. Warren Hunt in 1950.<ref>Hunt, C. Warren, 1950. Preliminary report on Whitemud oil field, Alberta, Canada; The [[American Association of Petroleum Geologists]] (AAPG), [[AAPG Bulletin]], vol. 34, no. 9 (September), pp. 1795-1801.</ref>

==Lithology==
The Ellerslie Member is composed of fine grained [[sand]] with sandy [[shale]] and shaley sand lenses in the upper part, and medium grained [[quartz]] [[sand]], [[siltstone]] and [[coal]] in the lower part.

===Hydrocarbon production===
[[Petroleum|Oil]] is produced from the Ellerslie Member in [[southern Alberta]] and [[central Alberta]].

==Distribution==
The Ellerslie Member Lateral reaches a thickness of {{convert|40|m|ft|-1|abbr=on}} (Upper Ellerslie) and {{convert|30|m|ft|-1|abbr=on}} (Lower Ellerslie). It occurs in the sub-surface in central and southern Alberta and south-western Saskatchewan.

==Relationship to other units==

The Ellerslie Member represents the lower part of the [[Mannville Group]] in southern and central Alberta. It is conformably overlain by the [[Ostracod Beds]] of the Manville Group and rests [[unconformity|unconformably]] on [[Paleozoic]] strata such as the [[Banff Formation]] or [[Pekisko Formation]], often separated by a [[Detrital Beds|Detrital Zone]].<ref name=lexicon/>

It is correlated to the [[McMurray Formation]] in the [[Athabasca Oil Sands]] of north-eastern Alberta and the [[Dina Member]] in east-central Alberta and west-central [[Saskatchewan]].
