When one looks
for oil one first looks for a basin, for oil and gas are found principally
where in ancient times there existed a marine environment in proximity
to land.
One of the best students of basins has been Meyerhoff who
has studied and listed the significant basins of the world. In addition
to those parts of the ocean near land one would seek out the ancient
lakes and rivers, particularly those near the sea, although these
reservoirs would necessarily be less extensive than those found
in the ocean itself.
Deltas are
the prize, because they are located where an important river flows
into the ocean. The combination of the nutrients from the land and
the aquatic life of the river creates at the point where it flows
into the ocean a habitat for the feeding and breeding of vast quantities
of marine life. Although the link connecting the presence of aquatic
life in the past with the petroleum in the present, has never been
made, and how could it be, occurring so long before our present
day, but observations, common sense and experience have correlated
them.
Therefore, the search is for oil and gas, the searcher seeks
those types of ambiences, not in the present day, but in the distant
past. It so happens, however, that sometimes present deltas and
shorelines exist near where they did in prehistoric times. One
such example is the Niger delta. Another prime example is the delta
of the Mississippi River.
In the Cretaceous
era, when dinosaurs roamed the earth, the shoreline of what is presently
the Gulf of Mexico, paralleled the present shoreline just north
of the present day city of Baton Rouge. In each time period following
the Cretaceous the shoreline, always paralleling that of the shoreline
existing today, was located somewhat southward of how it had existed
in the prior era. So that, if today one looks for oil in the Miocene
period, a more recent era, the search is zeroed in on a shoreline
not too far north of the present one. The shoreline of the Oligocene,
the next important period, is found slightly to the north of that
of the Miocene.
The era in which the Wilcox sands were laid down, had its shoreline
somewhat north of that of that of the Oligocene.
The deepest
the drill bit has drilled in Louisiana, although some perfectionist
might cite a couple of wells that are questionable, is into the
Cretaceous. This is where the sands the Austin Chalk and Tuscaloosa,
two horizons that are now receiving a tremendous play in Louisiana
are found.
The Austin Chalk having been laid down more recently
than the Tuscaloosa will, as logic would dictate, be found overlapping
but extending somewhat farther north and less farther south than
the Tuscaloosa. Since the shoreline of the Gulf of Mexico has migrated
southward in a parallel manner over eons of time, this results in
South Louisiana containing substantial oil and gas reservoirs from
all of those time periods.
After
finding an old marine basin, the oil explorationists then look for
traps. These are basically of two types, structural or stratigraphic.
An oil or gas field is simply an underground compartment containing
oil or gas usually found in an old marine ambience. It is, of course,
also necessary that the escape into the atmosphere of the oil and
gas has been prevented by some type of seal.
When sedimentary beds
have been pushed up from below, in Louisiana often by the underlying
salt, and become more elevated than the surrounding beds, then the
oil and gas intermingled with the water in which it was formed rises
above it and separates from the relatively heavy water. The other
factor, the lid that seals the top of the storage tank, is usually
a bed of shale or other layer of much more dense constituents than
the sands in which the oil or gas is found. Another type of oil
storage compartment, or field, is called statigraphic. If the sedimentary
beds are inclined at an angle, and if they change from their sedimentary
or sand character to denser and impermeable rock forming a seal
beyond which the oil or gas cannot penetrate, then the oil and gas
may have escaped from the water below into that horizon and risen
to the upper portion of the stratum to create an oil or gas field.
This latter type appears to have less significance in Louisiana
where most oil and gas fields seem to be structural.
In South Louisiana
the two principal types of structures are those created by salt
domes and those which lie along faults. Nearly all salt domes in
South Louisiana are productive. There the rising salt has pushed
up the sands above and alongside it to high points relative to the
surrounding sands forming perfect oil and gas traps. The other interesting
mechanism for the creation of traps are related to large faults
where what were formerly parallel beds of sand or shale has been
split by a fissure which divides the area into fault blocks, one
where the sands have risen, the "upthrown block" and one
where the sands have declined, the "downthrown block".
Due to subsequent declivity in the beds the oil and gas rise to
the more elevated areas of the sands in which they are located,
forming a productive reservoir. So that one often finds the fields
lying along the fault as one distinguished geologist and friend,
Grover Murray, called "link sausages".
The links, where
the sand is thin, do not produce, but when one gets to the sausage
that is a different story. One with enough experience in studying
the geology of an area can almost predict where a field should be
found. From that it is a relatively easy step into determining whether
the area has structure, from the electrical logs of wells, if there
has been drilling in the area, or from seismic data if the area
has been "shot".
Of the continental United States, South
Louisiana has best ambience for the discovery of oil and gas fields
as has, in fact, been proven. There are many more to be discovered
there.
Of all the modus
operandi of the human brain one of the most prevalent and effective
is pattern recognition. For that matter this even applies to the
brains of animals. If the master of a dog reaches for his hat the
dog gets excited. The dog thinks he may be going for a walk. He
associates that adventure with his master's movement.
To allude to
the higher level of human output, the patterns of which Beethoven
is cognizant permit him to produce compositions that relate to those
patterns, while still diversifying from them.
From its inception
the oil business has been replete with examples of pattern recognition
that were later rewarded. The story of the Oklahoman noticing his
train being slowed across terrain that was imperceptible to the
eye as an incline, and later discovering oil there, whether true
or not, is illustrative.
Colonel Lucas,
was a German whose career had been spent looking for salt. When
so engaged, he noted the affinity between salt domes and oil and
gas reservoirs. When told there was a salt dome at Spindletop he
drilled for oil there and discovered a giant field. When told that
another such a salt dome existed at Jennings, he drilled there and
discovered another lush reservoir.
Many examples
could be furnished highlighting the importance of pattern recognition
in the discovery of oil and gas reservoirs. Pattern recognition
is susceptible to mathematical analysis. Though some of the oil
pioneers were experts at eye-balling, that gift seems to have disappeared.
This is where the computer comes in. It is particularly adaptable
to pattern recognition. This is one of the most exciting domains
that the computer leads us into.
OilGasTech
hopes to take full advantage of this innate capability and is working
with gurus abreast in the field.
The
Focused Approach
The focused
approach entails the long time study of an area and careful selection
of targets. A company which rushes in is likely to use geologists
that have not worked an area to select its drilling spots. This
greatly decreases the chance of success. The optimum path is one
that lies between the scattershot approach of the sudden invasion
without sufficient planning and the methodical snail’s pace
approach of most major companies.
Discovery
by Independents
It is generally
conceded that the bulk of the oil and gas discovered in this country
has been found by independent companies, often small staffed with
individuals who have participated in drilling wells in the particular
area and who customarily may have studied thousands of electrical
logs from wells drilled in the region. Thus, the independent with
sufficient experience and knowledge of a region may move precisely
and expeditiously, but unhampered by the excess baggage of a major
oil company, with its huge administrative costs and committee system
of decision making.
Individuals
Colonel
Lucas
The oil discoverer
is much like the consummate artist who combines expertise, which
imposes the necessary restraint, with a certain abandon that achieves
the creative result. Significant oil discoveries and advances in
the techniques of finding them have been made by individuals who
were not in a specific scholastic niche but who combined wide experience
and novel approaches in their search. The first advocate of the
anticlinal theory, the now accepted explanation of how oil and gas
occur in "underground hills", was a medical doctor in
Pennsylvania. Colonel Lucas, the discoverer of
Spindletop, came into the oil business serendipitously. He was an
expert in locating salt for its value alone. From his work in looking
for salt he was struck with the insight that there was an affinity
between the presence of salt and the occurrence of oil.
Why
not the Seven Sisters?
Although a Company
such as OilGasTech can hit upon worthwhile purchases of oil production,
including oil royalty interests, the salient effort it will make
is in finding the new field, the real bonanza in the oil business.
One wonders, as it is grasped that the energy business and its oil
and gas components are here to stay, why it is not recommended that
one purchase stock in one of the Seven Sisters. The answer is that
purchasing stock in one of the major oil companies is not dissimilar
to putting money in the bank and drawing interest on it. There is
not much risk of loss. On the other hand, if a company has millions
of shares out, even the discovery of a Spindletop will have relatively
little impact on the share value. Investment in a major oil company
is really an investment in the general economy more than an active
investment in the oil and gas sector.
With respect to investment
in a company like Chesapeake, the answer there is that the stock
price has declined as often as it has advanced, and though well
financed, the company seems to have relied more upon stock market
reaction than in finding the molten gold. The success reapers in
the oil business have been those who have invested with a small
group that found an oil field. The record is replete.
"Doc"
Pennington
We could cite
many such individuals, all of whom we have personally known. One
is C.B. "Doc" Pennington. He was an optometrist
by training who became interested in the oil business, and shut
down his optometrist office and embarked upon the oil business.
He learned geology in a practical manner, consulting with many geologists,
raising money from friends and acquaintances to drill wells on prospects
that he had leased. He had found some oil in the Darrow and Lobdell
Fields in Louisiana. He became interested in the Port Hudson structure
right north of Baton Rouge. He went to see Edward Eagle Brown, the
Chairman of the First National Bank of Chicago who owned a thousand
acre plantation there. He wanted to obtain an oil and gas lease.
But Brown, who was then in his nineties, said he would prefer to
sell him the property.
When Pennington demurred saying he could
not afford it, Brown replied, "I will lend you the money",
and the sale was passed. Pennington induced Amoco to drill a Tuscaloosa
test there. The result was that Pennington became one of the wealthiest
men in the country, donating some one hundred and twenty-five million
dollars for the funding of the Pennington Biomedical Center.
Others
One of the landowners
at Port Hudson, Talmadge Bickham, who obtained
a twenty per cent royalty on his lease had one good well on his
property. With its proceeds he bought a Hilton Hotel, office buildings
in New Orleans, various other properties, and still lived in high
style. The well after eighteen years on stream is as productive
as ever. It is in the Tuscaloosa formation. There are many other
examples, such as Hugh Hawthorne of Lafayette, Louisiana. He adopted
ten Irish children, after which they would not let him adopt any
more.
He purchased property from the Burton Lumber Company for fifty
dollars per acre, sold the timber for that price and then discovered
the LaPice oil field on it. Needless to say after his concentrated
efforts in drilling wells in South Louisiana he left a very substantial
estate. Many other examples could be provided, and although, the
"rags to riches" cliche’ has been overworked, South
Louisiana has certainly provided the scenery for it to be played
out.
An area in
which new companies entering into the South Louisiana environment
in search of oil or gas are deficient relates to networking.
The
smaller companies which have long operated in the area, and their
principals, usually personally know a number of the landowners,
including those who have extensive holdings, and they know many
of the oil operators and geologists who have spent time and effort
in the area. There is a constant interchange of information. This
enables a company to acquire attractive leases easier, and, even
more importantly, to put together the myriad geological facts and
data which lead to the skylighting flame that flashes across the
pit of a well being brought in. Embassy has recently taken on board
as a consultant, one geologist who was the prime mover in discovering
six oil and gas fields, and clearly meets its tests.
Embassy is
negotiating with a company that has a significant repository accumulated
over the years of seismic readings and other data. If agreement
can be reached, the combination of this data with Embassy’s
own lists of potential reservoirs, gleaned from the work product
of a group of enlightened geologists and oil finders, should have
beneficent results.
In some businesses,
such as retail sales, a large company has inherent advantages. One
business, in which there are some decided advantages in a smaller
size is the oil business.
The oil pioneers
were men who knew all the facets of the oil business. They knew
something about geology, drilling, land ownership and other details
of the business having been involved in each aspect. They could
also move quickly.
A large percentage
of the oil discovered in the United States was discovered by independents.
The modern big integrated oil company is extremely compartmentalized.
The process of finding oil is broken down into landmen, geologists,
petroleum engineers who are divided into reservoir specialists and
exploration specialists and further divided into geographical areas.
Decision making is by committee. Compared to a smaller independent
the process moves at snails pace.
Embassy can
move overnight and take advantage of any sudden opportunity, which
as all experienced oil men [generic sense] know, occurs not infrequently.
Timing, though important in all business, is critical in the oil
business. |
