ICCATICN

T;e Reynolds field is in the northwestern nart of
i‘-1ontcalm County and the extreme southwestern hart of Mecosta
Cruntv, Michiean. The field is situated about three miles
north of Howard City and one nile south of the snall town of
Morley. Hiehway U. S. 131 runs throufih the western part and
State Hiihway he passes through the southern nortion of the
field. All wells drilled in this area are easily accessible
from roads conqectine to the nain hiehways.

The productive area of the Reynolds field lies pri-
marily in Sections 1, 2, l2, and 13 of T. 12 F., R. 10 W;
sections 6, 7, 17, and 13 of T. 12 N., R. 9 W; and the 8%
section 36 of T. 13 N., R. 10 W. Fiaures 1 and 2 show the

location of the Reynolds oil field.

PHYSIOGRAPHY

Surface features in this area have been determined by
glacial action and erosion. A noraine trending northeast-
southwest is located in the northern part of the field.
However, about seven—eirhths of the surface in the field
area is part of a till plain. The gently rolling land varies
in elevation from 900 feet above sea level in the western
and southern part, to 960 feet above sea level in the north-
east.

Most of the farms in the area are snall, averaging 30

acres.

-JJ—

Two streans flow throueh the area and enter the Muskeeon

River at points northwest of the field.

HISTORY AND DEVELOPMENT

A shallow well was drilled to a denth of 1,150 feet in
1935 by Edward Stewart in NE.£, SE.£ of Sec. 17, T. 12 N.,
R. 9 W. It yielded gas at the rate of 1,430 million cubic
feet her day from +he "Stray" sandstone neqher of the
Michigan formation.

.The Haines No. 1 discovery well opened the Winfield gas
field. Subsequent drillinr revealed {as in many other
locations.

A well drilled in 1936 by the Daily Crude Oil Conpany
in the SW.£, SW.L, of Sec. 20, T. 12 N., n. 9 N., discovered
oil in the "Reed City" dolomite of the Dundee foruation at
a depth of 3,3t0 feet.

Further drilling resulted in five producinz wells in
the Winfield pool, ami in July, 1957, one well was still
producing. The accumulative production to July, 1957 was
68,293 barrels of oil.

Meanwhile, the Carter Oil Conpany had leased property
north of the Winfield field. They farmed out these leases
to the Tagaart Comoany with the agreement that if they uid
not develop this area, they would relinquish it to Carter.
The Tageart Commany proceeded on an extensive drilling

Droqram and found many more "Stray" aas wells. In the summer

-4-

of 1938, one of these wells, the Jacks Estite No. 2, in the
NE.£, NW.£, NW.£ of Sec. 7, T. 12 N., h. 9 W, was drilled
deeper into the "deed City" dolomite of the Dundee formatioi.

t a depth of 3,3h6 feet, a "show of black, dead oil" was
reported. The infornation was not released until the early
1950's. Two consulting geoloeists, Jack Mortenson and
Manley Oseood, discovered a driller's log furnished by the
driller of the well. Examination of the sanples from the
well indicated the presence of oil.

iineral riehts were leased in the vicinity of the well,
and subsequently, Osaood and Mortenson persuaded McClure Oil
Connany and Associates to drill the Kohn No. l in the SE.£,
SE.£, NW.£ of sec. 1, T. 12 N., R. 10 w. On March 20, 1954,
oil was discovered at a depth of 3,3h3 feet in the "Reed City"
dolomite of the Dundee formation. The well flowed initially
132 barrels of h2.60 gravity sweet crude oil per day. Devel-
0pment of this field was rather slow and by the end of 1955,
only eiaht producing wells had been drilled.

Since the discovery of the Reynolds field, A6 flowing
wells have been drilled to the "Reed City" dolomite.

The A. Williams No. l, drilled by the McClure, Swan-King,
Basin Oil Companies and G. Ackerman in the SE.£, NW.£, SE.£
of Sec. 1, T. 12 N., R. 10 W, was dry in the "Reed City"
dolomite. It gave a eo‘d show of oil in the upper part of
the "Traverse limestone" and just below the "Traverse forma—

tion," In Auaust, 1955, the well was plugged back to a depth

l"

c.)-

of 2,792 feet and after acidizing, it pumped 15 barrels of
oil per day and some water in the "Traverse limestone".

Since this discovery, six punoing wells and one flowing
well have been drilled into the Traverse Groun.

Production from the Traverse wells has been limited and
has furnished a ninor part of the oil in the Reynolds field.
The Traverse has produced 43,7h3 barrels and the Dundee has
produced 1,067,210 barrels of oil as of August 31, 1957. Due
to its limited production, the Traverse portion of the field
has not been restricted by conservation practices. The
.Dundee production has been the main concern of the Conserva-
‘tion Department of the State of Michiqan.

The development of the Dundee portion of the field has
tween under the constant surveillance of the Petroleum Engineer-
iJig section of the State Geological Survey Division since
fihrrch, l95h. Forty acre spacing of the wells has been used
frmxn the first discovery of the field. Production in the
foxeld has been prorated, and in Aurust, 1957, each well was
ILhnited to 50 barrels of oil per day.

Periodic investigations of the field by the Petroleum
Enziudeering section have furnished such basic reservoir
ihdxlrmation as gas-oil ratios, bottom hole pressures, and
edema water encroachment. Regulations based on these inves-
ti?FItiens have greatly aided the development and increased
the life of the field.

Although there are a number of undrilled locations, the

-6-

present Spacing has fairly well delineated the production
limits of the field. Dry holes have penetrated the "Reed
City" zone and determine the western, southern, and northern
limits of the field. Wells recently drilled in the eastern
portion are producina both oil and water, indicating the
possibility of a termination of the field in this direction.

The average product on per acre to date is 580 barrels.

Preparation of Samples:
Two types of samples were used, those received directly
.from the drillers and these which were previously washed and

lxottled. The sanpl 5 received from the drillers were furnished

tfirrouqh the cooperation of Jack Mortenson, and the other
sannnles were furnished mainly by the State Geological Survey.

Wfiyo sample sets were furnished by the Sun Oil Company. For

a (:omplete inventory of the saqples used in this report see

pages 12 and 13.

Samples received from the drillers were contaminated
‘Witfli mud and had to be washed and dried prior to microscopic
eXiarnination. The sanples were poured into a small saucepan
untdfll it was approximately half full. The pan and sample were

theri placed under a small, slow stream of water and agitated.
Thiss process of shaking the pan tended to loosen the mud
frond the samples and caused it to become suspended in the
watexr. The mud-filled water was decanted and the process

repgated until the water vas Clear. The wet sample was then

-7-

drvied over a stove. Dried samples were placed in manila
enxrelopes that had been previously marked with the corres—
porvding well nanes and footages.

It was more efficient to wash 20 sanples at a time,
pléacze them on a large aluminum pan, and dry them on a large
tmvch—burner gas stove. While this nroup was drying another

vmerwe washed for sample examination.

Exanination _o_f_ the Samples:

 

 

After completion of the washing and drying process,
micxroscooic examination of the samples was accomplished.
Thea eduinment used in the examination was as fo lows:

l. Binocular microsc

pover from 9X to 36X
2. Scoop tray
3. Steel teasing needle
b. Small pair of forceps
5. Shall horseshoe mafinet
6. Table lamp
7. Acid dish
8. Ten per cent hydrochloric acid

9. Toothoicks

The sample was examined for contamination caused by the
DreSence of steel shavings from the drill bit. These shavines
Werwe renoved by passing a horseshoe madnet over a piece of
paTwér'that was lyina on top of the same e. The paper and

mafirhet were then raised toaether to remove the shavings.

This nrocess kept the nannet Clean for future use.

Samples rare then distributed evenly on the scooh tray
and.pdaced in the illuminated microscopic field. For most
cm? the work a magnification of 12X vas sufficiently strong.
lkywever, for the insnection oi finer detail such as identi-
incation of nicrofossils, a meanification of 27A was used.

hardness was determined by holding the sannlc with the

L

ikorceps and scratching xith a steel teasing needle. Forceps
snare also used for removing a sample for future testing, and
s1 \vetted end of a toothpick was used to remove the fine
rnarticles.y

Chins were removed and placed in an acid dish containing

:ncnanted on slides.

For other imwortant lithologic characteristics such as
c<>l<n3 stain size and train shape, various charts and diagrams
\"exée constructed previous to the exanination. An explanation
of‘ the adjectives used in describing the lithology of the
sannoles is contained in the following outline ihich has been

mootified from Low's, Examination 9: Well Cuttings, p. 9-20.

 

 

A. Coarse elastic rocks (sandstone)
1. Color - The colors of red, sray, brown,

The litholoaio description of each sample was recorded

on a pad of paper beside the microscope. This process

continued until the sa’iples from one well r-Jere finished.

Forrnai'ional and lithologic breaks were then determined from

the comoleted sample lcn.

Since the fossils found in the samples were fragnen-

tary, making identification difficult, the formational breaks

have been chosen by means of lithologic characteristics. In

one case, fossils were of value in seoarating two formations

'v'here the litholcnj,r was very similar. Cavings were common

in many samples examined. neviev; of existing descriptions

of nearby wells, along, with the co m‘uarison of samples

reviously examined, aided greatly in dieting-jwjuisl'ling cavings

fro m other rocks .

The inventory of samnles used in examination is shown

in chart form on pages 12 and 13.

The names used for identifying the mUhSUPfHCG forma-
tions in the Reynolds field are those which have become
00mmon usase in nearby oil fields. Wells in the Reynolds
field er4a averafie 3,350 feet in depth. The subsirface
horizons are eesily identified and there are a number of key
beds exemplified that are continuous and regular throughout
the field. The stratifiraphy of the field has been known
since the discovery of the Reynolds nool, because it is
similar to other nearby fields where the yeoleic sections
have been previously described. However, no 0 mplete and
detailed report has been made of the Reynolds field's stratig—
ranhy.

Figure 3 shows the grathic representation of the geolog-
ical column and e fihasizes the prominent beds identified.
A type sample 109 of t.e field is seen on pages 33-36. This
Will dive a connlete ricture of the litholoay obedrved in
each well examined.

Pleistocene:

 

The Pleistocene section is represented by deposits
consisting largely of gravel, sand, clay, and pebbles. The
drift section ranges in thickness from 350 to 550 feet. An
isopach map of the drift is in Figure A. The great variation
in thickness of the drift nay be attributed to the differing

intensities of filacial activity and to postglacial erosion.

Perno—Carboniferous:

Below the drift is a section

f red Clay, .nud, gypsum,
sand, and shale that is commonly referred to es the "Red

_1

Beds". The exact age of this formation has been a rather

(I)

controversial subject, but recent ieolopists hav placed
it in the Perno-Cnrboniferous. The beds range in thickness
from 80 to 150 feet. This larze range of thickness can be
attributed to unequal erosion cau,ed by the glacial ice
and nreglacial erosion.
Pennsylfinuiian:

This system is renr5~ented in the area by two formations,
the Saginaw and the large.

The Seqinav fora tion is coprsed of gray, dark grey,
and black shales; white and light gray, medium to coarse
grained sandstone; and some grey-brown, very finely crystalline
limestone. The formation ranges in thickness fron 90 to
120 feet.

The Parna formation consists of white to grey, medium
to coarse trained sendstone. In host of the wells examined,
however, the litholoaic break between the Ferns and the
underlying Bayhort limestone wes indistinnlishnble. This
could indicate that the upper Bayport has been reworked to
form the sediments of the lower Parma. The Parna sandstone
ranses in thickness from 15 to 30 feet.
