EXECUTIVE SUMMARY

This report presents the results of a re-evaluation of the Jurassic – Tertiary stratigraphy of four southern

Newfoundland margin wells (Laurentian, South Whale and Whale Basins); East Wolverine G-37, Eider

M-75, Emerillon C-56 and Narwhal F-99, carried out on behalf of Nalcor Energy.

Biostratigraphic (palynological and micropalaeontological) and lithologic analyses have been carried

out on the following well sections, in order to establish a revised, internally consistent and regionally

correlative stratigraphic framework.

East Wolverine G-37: Middle Miocene, Serravallian – Bathonian / ?Bajocian

Eider M-75: Early Maastrichtian / Campanian – Aalenian / ?Late Toarcian

Emerillon C-56: Late Campanian – ?Sinemurian / Hettangian

Narwhal F-99: Early Pliocene – Berriasian – Volcanics

This study, commissioned by Nalcor Energy, is a continuation of our earlier well studies carried out as

part of a much larger regional assessment of the slope and deepwater prospectivity of the offshore

Eastern Canada Newfoundland / Labrador margins, with the aim of improving shelf-slope-deepwater

stratigraphic correlations.

2. OBJECTIVES

A biostratigraphic / lithostratigraphic study of four wells (East Wolverine G-37, Eider M-75, Emerillon

C-56 and Narwhal F-99) has been carried out as part of a larger regional assessment of the hydrocarbon

prospectivity of the southern Newfoundland margin (Laurentian, South Whale and Whale Basins) with

the goal of improving the interpretation of shelf-slope stratigraphic correlation. The East Wolverine G-

37, Eider M-75 and Emerillon C-56 wells were chosen by Nalcor as representative datasets that cover a

range of stratigraphies in the slope and deepwater regions in the Southern Newfoundland area. The

Eider M-75 well, which is located on the shelf, was selected due to its encountered stratigraphy

coverage and also as a representative dataset for the shelfal Whale Basin.

The study attempts to present a revised, internally consistent and regionally correlative Jurassic to

Tertiary biostratigraphic (palynological and micropalaeontological) and lithostratigraphic framework.

Newly prepared ditch cuttings samples obtained via the CNLOPB have been used throughout the four

well study. These biostratigraphic datasets are to be integrated into a regional seismic interpretation,

providing the foundation for extending the basin-to-basin tie lines, as well as anchoring the

interpretations away from the shelf and into the slope and deepwater regions that lack well control.

The southern Newfoundland margin (Laurentian, South Whale and Whale Basins) is situated to the

north-northeast of the Scotian Shelf, southwest of the Jeanne D’Arc Basin and west of the Carson -

Bonnition Basin. The drilled sequences occurring within the Laurentian, South Whale and Whale

Basins, include sediments which are comparable to those recorded from both the Scotian and Jeanne

D’Arc Basins. As such a “best fit” lithostratigraphic nomenclature for these Laurentian, South Whale

and Whale Basin wells, has been taken from both the Scotian and Jeanne D’Arc Basins; following

published schemes of Jansa and Wade (1975), McAlpine (1990), McIver (1972) and Wade (1981).

Chronostratigraphic terminology follows Gradstein et al. (2012).

Tertiary micropalaeontology is based on Ascoli (1976, 1988), Charnock & Jones (1990), D’Iorio

(1986, 1987), D’Iorio & Agterberg (1989), King (1989) and unpublished personal observations.

Mesozoic micropalaeontology follows Ascoli (1976, 1981, 1988a, b, 1990), Ascoli et al. (1990), Exton

and Gradstein (1984), Gradstein (1975, 1976, 1978), Gradstein et al. (1975), King et al. (1989), Stam

(1986), Williams et al. (1990), Williamson (1987) and unpublished personal observations.

The Jurassic – Tertiary palynology is largely based on Barss et al. (1979), Bujak & Williams (1978),

Fensome et al. (2009), Gradstein et al. (1975), van Helden (1986), Williams (1974), Williams &

Brideaux (1975), Williams et al. (1990), plus Williams and Bujak (1977) and unpublished personal

observations.

5. CONCLUSIONS

The following conclusions are noted:

1. ?Iroquois Formation

This sequence of sediments only occurs in the Emerillon C-56 well. It has only been tentatively

assigned to the Iroquois Formation, based on lithological criteria (red and green-stained

claystones, interbedded with dolomites and locally anhydrite beds). A tentative Hettangian /

Sinemurian age has been assigned based on regional criteria.

2. The Downing Formation / Downing Formation Equivalent / Whale Member

The Downing Formation is present, as a thick sedimentary package, in three wells (East

Wolverine G-37, Eider M-75 and Emerillon C-56). It has a maximum stratigraphic range of

Pliensbachian? / Early Toarcian through to Late Bathonian.

The Downing Formation exhibits a wide variation in facies; in the Emerillon C-56 well, the

sedimentary sequence is dominated by limestone (often oolitic) indicating a shallow, high

energy marine environment, whereas in both the East Wolverine G-37 and Eider M-75 wells the

sequences are more argillaceous, indicating deeper water, more tranquil, marine environments.

The Whale Member of intra-Bajocian age is only seen in the Eider M-75 well.

3. Voyager Formation / Voyager Formation Equivalent

This marginal marine to inner sublittoral sedimentary sequence, as seen in East Wolverine G-

37, Eider M-75 and Emerillon C-56, has an observed stratigraphic range of Late Bathonian to

“Middle” Callovian.

No Late Jurassic (Oxfordian – Tithonian) are preserved in the four well sections studied.

4. Verrill Canyon Formation / “Middle Missisauga Member”

The Verrill Canyon Formation is recognised in two wells, East Wolverine G-37 and Narwhal F-

99. It has an observed stratigraphic range of Berriasian to Late Barremian.

Thin “Middle Missisauga Member” sandstones are of Berriasian to Early Valanginian age.

Well-developed limestone units are also noted in the Narwhal F-99 well.

5. Missisauga Formation

The arenaceous Late Barremian – earliest Aptian, Missisauga Formation, is only recognised in

the Emerillon C-56 well.


_______________________________________________________________________________________________________

17

6. Logan Canyon Formation, Naskapi Member

Aptian, Naskapi Member, sediments occur in the East Wolverine G-37 well and they may also

be present in the Emerillon C-56 well. Large numbers of planktic foraminiferids suggest a more

open marine environment in East Wolverine G-37, than that inferred in possible correlative

sediments in the Emerillon C-56 well.

8. Logan Canyon Formation

This predominantly arenaceous sequence Aptian aged sediments is only seen in the Emerillon

C-56 well. It is envisaged to have been deposited in a transitional to inner sublittoral marine

environments.

9. Shortland Shale / Shortland Shale Equivalent

The Albian, Shortland Shale only occurs in Narwhal F-99. These sediments are envisaged to

have been deposited in an inner sublittoral marine environment.

A slightly deeper water, low energy, marine environment (Shortland Shale Equivalent) is

recognised in the East Wolverine G-37 well.

9. Eider Formation

These unconformity bounded, marginal marine / inner sublittoral sediments of Late Albian /

Cenomanian age are only recognised in the Eider M-75 well.

10. Eider Formation Equivalent / Shortland Shale

A transitional series of sediments (Early – Late Albian) between the marginal marine / inner

sublittoral Eider Formation Equivalent and the inner sublittoral Shortland Shale is recognised in

the Emerillon C-56 well.

11. Dawson Canyon Formation

The Dawson Canyon Formation is present in all four well sections; with an observed

stratigraphic extent of Cenomanian - Late Campanian / ?Early Maastrichtian.

All three members are recognised; “Lower Dawson Canyon Member” (Cenomanian), Petrel

Member (Early – Middle Turonian) and “Upper Dawson Canyon Member” (Late Turonian –

Late Campanian / ?Early Maastrichtian). Highly attenuated, and unconformity bounded

sequences are recognised in both the East Wolverine G-37 and Narwhal F-99 wells.

12. Wyandot Formation

The carbonate Wyandot Formation (Late Campanian in this study) occurs in both East

Wolverine G-37 and Emerillon C-56.


_______________________________________________________________________________________________________

18

13. Banquereau Formation

The Tertiary Banquereau Formation is recognised in both the East Wolverine G-37 and Narwhal

F-99 wells, with a stratigraphic extent of Late Paleocene, Selandian to Early Pliocene, Zanclean.
