ABSTRACT
The study area lies in southeastern Saskatchewan and is located
five miles west of the Manitoba border and twelve miles north of the U.S. -
Canadian border .
The regional dip is generally southwe.st into the Williston Basin .
Post-Mississippian, Pre-Jurassic erosion bevels all of the strata under
discussion with the oldest, the Tilston Beds, subcropping at the northern
limits of the study area and the Frobisher, the youngest, at the south. The
structure is monoclinal and demonstrates no unusual features .
The eroded surface of these Mississippian rocks exhibit character
istics of a mature landscape. The Mississippian strata are overlain un
conformably by the Mesozoic Watrous Formation.
Accumulations of petroleum occur in seven separate reservoirs
over the area, usually fairly close to the top of the eroded Mississippian
strata.

INTRODUCTION
The area under examination lies in southeastern Saskatchewan
and includes all of Townships 3, 4 and 5, Ranges 31 and 32, west of the
Prime Meridian, plus some adjacent areas (Figure 1).
The reservoir rocks involved in this report all fall within
the upper portion of the Madison Group of Mississippian age (Figure 2).
The dip is to the southwest into the Williston Basin and the structure is
a simple monocline with no complicating features of any magnitude apparent.
Limestones constitute the greater part of the section with
dolomites and anhydrites occurring throughout. Subordinate amounts of
sandstones, siltstones and shales also occur.
The southwesterly dipping Mississippian beds were bevelled by
a long period of erosion and the contact with the overlying Mesozoic strata
is marked by an angular unconformity . The hiatus represents a period of
time possibly extending from Upper Mississippian to Jura-Triassic. The
eroded surface of the Mississippian carbonates ,=xhibits a mature topography
with a well dissected upland and generally wide valleys. The occurrence of
hydrocarbons in the several pools of the area i :s related to the morphology
of this eroded surface.
None of the rocks covered in this paper outcrop within the
study area nor within the province .

STRATIGRAPHY AND LITHOLOGY
General
All strata discussed in this report: occur within the upper
portion of the Madison Group of Mississippian age (Figure 2) , The lowest
beds considered are those of the Tilston which are Upper Kinderhookian in
age (Brindle, 1960, pp. 17-22). The Tilston Beds are the equivalent of the
MCl and MC2 (Mission Canyon 1 and 2) of Thomas (J.954), I n general, the
Tilston Beds are limestones which tend to be argi.llaceous or, in places,
dolomitic.
Above the Tilston Beds lie the Frobisher-Alida Beds which are
of lower Osage age (Brindle, ibid.). Within the study area the Frobisher
Alida Beds may be divided, in ascending order, as follows: Alida Beds,
Kisbey Sandstone and Frobisher Beds, Over much of southeastern Saskatchewan
it is difficult to divide the Frobisher-Alida Beds in this way as distinctive
markers are not persistent over any great distance, Within the study area
such a division is generally possible, though local l y some difficulty may be
encountered.
The Alida Beds are the equivalent of the MC3 of Thomas and they
rest conformably on the Tilston Beds . For the most part they are carbonates,
both limestones and dolomites, but sandstones and siltstones occur in minor
amounts . The latter are of limited areal extent.
The Kisbey Sandstone occurs immedicttely above the Alida Beds
and was termed the MC4 by Thomas. At a particulctr locality it may be a true
sandstone, a siltstone or an argillaceous limestone. In thickness the Kisbey
varies between 7 and 20 feet, and in this area, i.t is normally picked with
l ittle difficulty on mechanical logs or in cores.

The Frobisher Beds, the MCS of Thomas, lie on the Kisbey Sandstone.
Generally, the Frobisher Beds are limestones, s,ome of them dolomitic. In the
southwestern corner of the study area evaporite:s are abundant.
In the southwest of the area under ,~xamination the Midale Beds
(Figure 5) rest directly upon the Frobisher Bed:s. These are carbonates and
evaporites and have only limited ar ea l extent within the confines of this
paper. The Midale Beds are Osagean in age (Bri1ndle, ibid.). As they have
no economic importance in the area under discus1sion they will receive no
further mention.
Immediately below the contact of th,e eroded Mississippian carbon
ates and the Lower Watrous Formation the Missis:sippian strata are dolomitized
and contain much secondary anhydrite . The anhy,drite was deposited from
solution in the weathered zone and this infilli:ng, together with the shales
of the Lower Watrous Formation, forms the seal ·retaining the hydrocarbons
which have migrated into the positive topographic features of the erosion
surface.

OVERLYI NG BEDS
Overstepping the Mississippian strata are the red silty and
sandy shales of the Lower Watrous Formation. Th,e sandy and silty zones
are especially abundant toward the base of the f ,ormation. Minor evaporites
are present locally. The contact with the Mississippian carbunate s is
marked by an angular unconformity . This break r e presents an hiatus which
extended probably from late Mississippian time to the Jura -Triassic and
wa s likely a period of both erosion and non-de position .
Milner and Thomas (1954) placed the Lower Watrous in the
J urassic (possibly Triassic in part) . Francis ( 1956) placed his "Red Beds"
in the Jura-Triassic and indicated that they are the equivalent of the
Watrous of Milner and Thomas.
Francis (ibid.) suggests that the Lower Watrous Formation is
partly of continental origin and is of the opinion that one or more un
conformities exist though lithologic evidence is lacking. To date no
diagnostic fossils have been found .
UNDERLYING BEDS
Below the Tilston Beds lie those of the Souris Valley . These
are Kinder hookian in age (Brind l e, 1960-. p. 17) and form the lowest unit
of the Madison Group . They are argillaceous lirrtestones with some zones of
fossils and fossil debris. In t he study area the Souris Valley Beds become
incr easingly argillaceous as the contact with the Tilston Beds is approached.
I n t he a r ea under examina t ion, the Souris Va l ley Beds have not, as yet, pro
duced oil or gas . This may be attributed to the: fact that because they do
not subcrop in the area of s t udy t hey do not form positive topographic
features which a ppear t0 be invariab l y associated with the accumulation of
hydrocarbons in the area.

PALEOTOPOGRAPHY
The map of the eroded Mississippian surface (Figure 4) shows
an alignment of the topographic highs and intervening valleys from north
east to southwest. The most highly dissected areas of the lands studied are
to the north and along the eastern side (Figure 4). Within these portions
of the study area are concentrated the producing oil pools.
The shallowest point observed on the eroded surface is found
in the F .H. Calstan Nottingham well (Lsd 8-21-5·-31 Wl) where the erosion
surface was cut at 3311 feet below K.B. (1500 foet sub-sea). The deepest
point noted was in the Homestead et al. CarndufJE dry hole (Lsd 12-2-3-33 Wl)
where the erosion surface is at 3929 feet below K.B. (2165 feet sub - sea).
In the northwest corner of the study area the Nottingham Alida
Beds Pool is shown on the erosion surface map as coincident with an elongated,
southwest-trending ridge which expands at its southern end to a broad hill
separated from the body of the ridge by a low saddle. This latter positive
feature is associated with the Oakley Frobisher Beds Pool.
Parallel to the Nottingham ridge and to the southeast of it is
another elongated topographic high which coincides with the Rosebank Alida
Beds Pool. It is separated from the Nottingham ridge by a broad valley
which narrows and steepens at the southern end between the Rosebank and
Oakley Pools.
To the east of the north end of Rosebank Alida Beds Pool is the
Storthoaks Alida-Tilston Beds Pool, which is located on another southwest
trending ridge parallel to the topographic high associated with Rosebank.
This ridge terminates at the southeastern end ojf the pool in a shallow
saddle or col beyond which the feature is continued. This continuation
coincides with the Rosebank South Alida Beds Pool.

East and south of the Rosebank South Alida Beds Pool is the
Ingoldsby Frobisher-Alida Beds Pool which occupies the site of a broad
hill of considerable area with a south-plunging spur at the southeastern
edge.
On the west side of the study area, west of Ingoldsby and at
the termination of the Rosebaak South-Storthoaks topographic feature, is
the Silverton Frobisher Beds Pool. This pool is marked by a small oval
hill. The pool is small and is now close to depletion. In topographic
relief it is the least prominent of all of the pools in the area and its
oil production is less than the others.
The close relationship of the well-dissected erosion surface
with oil production bears out Fuzesy's views on the Frobisher-Alida Beds
(Fuzesy, 1966, pp. 43-44): "Oil accumulated int the areas where reservoir
rocks are associated with topographic highs, these two factors determining
the position of cormnercial oil accumulations".

STRUCTURE
Within the study area the combination of dipping strata and the
bevelling effect of the erosion surface makes it impossible to select a
single mapping horizon to demonstrate the structure of the entire area , I n
addition, many of the wells do not penetrate the Mississippian strata deep l y
enough to reach any such horizon .
A structural map (Figure 6) has been drawn on the top of the
Tilston Beds which does give a map over most of the area . The part of the
area where the Tilston Beds subcrop (and hence where this top is missing)
is of small extent and comparatively few wells have been drilled there .
On Figure 6 the dip of the strata is shown to be to the south
west with the strike running from southeast to northwest. The dip averages
between 50 and 75 feet per mile ,
There is little in the way of local. structural features other
than the gentle nosing which is associated with some of t he oil pools.
This nosing , however, may be related to the minor folding of the Frobisher
Alida Beds noted by Fuzesy (1966, pp. 44) . In this paper Fuzesy indicates
that t his folding often coincides with the positive topographic features
of the erosion surface in several of the oil p~oducing areas of southeaster n
Saskatchewan. I n the lower portion of the Frolbisher-Alida beds trapping of the
hydrocarbons is related to the topographic highs and is largely structural
stratigraphic . In the upper part of the Frobisher Beds, outside the present
area, the relation of topography to oil accumulation is not close and the
trapping is largely controlled by variations in porosity and permeability of
the rocks (Fuzesy, ibid .).

PRODUCTIVE HORIZONS
Tilston Beds
The lowest productive rocks in the area under consideration
are those of the Tilston Beds. They average about 150 feet in thickness,
though this varies in different localities . The Tilston Beds are the
equivalent of Thomas's (1954) MCl and MC2. The lower part of these beds,
the MCl, is usually about 135 feet in thickness while the upper, or MC2,
portion is normally 10 to 15 feet thick .
The Tilston Beds were named by the Saskatchewan Geological
Society (Saskatchewan Geological Society, 1956) from beds at this strati
graphic level in the Tilston Oil Field in Manitoba .
The sediments are carbonates, usually fine grained. They may
be limestones or partially or completely dolomitized limestones . They
often contain oolites, crinoidal fragments and fine silty material. The
thinner upper part, the MC2, is usually silty and argillaceous and may be
dolomitic.
I n the study area Tilston Beds production is restricted to the
subcrop or areas immediately adjacent to the subcrop. It appears that the
trapping of Tilston Beds and Alida Beds oil is dependent on positive topo
graphic features on the erosion surface.
Tilston production in this area is confined to the Storthoaks
Al ida-Tilston Beds Pool where the Tilston Beds produce in the northeast
end of the pool, and the Nottingham Alida Beds Pool, where a few wells
produce Tilston oil in the northeast portion of the pool.
- 11 -
Frobisher-Alida Beds
In 1956 the Saskatchewan Geological Society (Saskatchewan
Geological Society, 1956) named the strata occurring between the top of the
Tilston Beds and the base of the Midale Beds, the Frobisher-Alida Beds,
The designation comes from those correlative beds found in the Frobisher
and Alida oil fields in Saskatchewan. They did niot subdivide the Frobisher
Alida Beds as no suitable dividing horizons were found that were regionally
persistent.
Within the study area the Frobisher-Alida Beds may usually be
divided in the following manner from oldes t to youngest (Figure 2): Alida
Beds (MC3), Kisbey Sandstone (MC4), and Frobisher Beds (MC5). This sub
division follows Fuzesy's (1960) comparison with Thomas's work of 1954
(Figure 2),
Alida Beds
The Alida Beds lie between t he Tilston Beds and the Kisbey
Sandstone. Brindle (1960, p. 25) indicates Osagean age for the Frobisher
Alida Beds.
The Alida beds vary from 150 to 200 feet in thickness. The
rocks are typically crinoidal limestones, fine to coars~ly sucrosic dolo
mitized limestones, fossiliferous limestones, ca]lcilutitic limestones and
sandstones and siltstones of limited areal extent. The beds may be oolitic
and pisolitic, though this is not common. Where porous the Alida beds
usually have intercrystalline or intergranular porosity.
Petroleum is produced from these beds in the Ingoldsby Frobisher
Alida Beds Pool, in the Rosebank Alida, Rosebank South Alida, Nottingham
Alida and Storthoaks Alida-Tilston Beds Pools.
- 12 -
The entrapment of hydrocarbons is dependent on positive topo
graphic relief and reservoir rock occurring together.
Kisbey Sandstone
The Kisbey Sandstone lies above the Alida Beds and directly
beneath the Frobisher Beds, and is the MC4 of Thomas (Thomas, ibid .). The
subcrop of this sandstone roughly divides the study area in half from south
east to northwest (Figure 5) . Edie (1958) notedl an upper a.nd a lower sand
at this point in the section. Fuzesy (1960) used the upper sand as the true
Kisbey Sandstone a s it is more constant and regi.onally identifiable . Other
sandy and silty zones occur in both the Frobisher and the Alida Beds but
their areal extent is limited .
In thickness the Kisbey Sandstone varies between approximately
7 and 20 feet. It is principally composed of quartz, feldspar and chert,
and is usually medium grained and well sorted. Within the study area at
different localities the Kisbey is a true sandst:one, a siltstone and an
argillaceous limestone. Where the overlying Frobisher beds approach the
erosion surface infilling may change the character of the curves of mechani
cal well logs. This, with the occurrence of st1ray sandstones and shales in the
section can make identification difficult .
The colour of the sandstone may be grey, brown or red. In places
it is current bedded and ripple marked indicating high energy and/or shallow
water deposition.
The Kisbey Sandstone produces oil in the Ingoldsby Frobisher-
Al ida Beds Pool but it is included in the Frobi:sher -Alida Beds which are
consider ed a single reservoir by the Saskatchew,an Department of Mineral
Resources.
- 13 -
Frobisher Beds
The Frobisher Beds are the youngest Mississippian strata re
maining over most of the study area , The Mida1le Beds of the southwest
are younger than the Frobisher but are not included in this report .
The Frobisher Beds conformably ove:rlie the Kisbey Sandstone
and are, in turn, overlain unconformably by the J ura-Triassic Lower
Watrous Formation in the study area. The Frobisher Beds average 170 feet
in thickness . They are mostly carbonates with algal, oolitic and piso
litic limestones occurring most frequently . T'hese limestones normal ly
have very fine crystalline matrices . There are also, in lesser amounts,
fine fragmental limestones, fossiliferous limeistones, argillaceous and
silty dolomitized limestones and lenses of sandstone and sil t stone.
Vuggy porosity is typical of the Frobisher Beds .
In the lower Frobisher Beds t he oc:currence of oil is governed
by the structural-stratigraphic conditions, as in the Al ida Beds . The
presence of oil in the upper Frobisher Beds depends on stratigraphic
conditions rather than structure. Within the s t udy area Frobisher produc
tion is confined to the lower portion of these beds.
I n the southwest of the area of study the Hastings Evaporite
occurs in t he upper part of the Frobisher Beds ( Figure 5) . Generally this
evaporite is found 10 to 12 feet below the top of the Frobisher Beds and
is overlain by non-evaporites, normally argil l aceous and silty limestones
and dolomites .
The Hastings evaporite varies in thickness from 35 to 102 feet.
As it nears its northern depositional limit it undergoes a lateral facies
change to carbonates. This change progresses upward from the base and at
the depositional limit the remaining evaporite is the equival ent of the
upper Hastings as it occurs in a full section.
- 14 -
The Frobisher Beds are productive in the lngoldsby Frobisher
Alida Beds Pool, the Oakley Frobisher Beds Pool and the Silverton Frobisher
Beds Pool.
