Accounting for Crude Petroleum Producers *
By GEORGE R. TURTLE
This article is intended to deal with the activities of the two principal classes of crude petroleum companies, namely, those engaged in producing crude oil and those developing or prospecting oil lands.
The growth of the petroleum industry in America has been very rapid within the last few years, and it is now common knowledge that the crude oil is obtained from beneath the surface of the earth, sometimes in oil pockets of rock formation, but more often in a certain formation of sand and shale.
To extract or draw the crude oil from the oil pockets or oil formations it is necessary to drill to varying depths—usually from 500 feet to 3,000 feet, according to the depth of the strata or sand in the particular district. The drilling may be done by the company's own employees with the use of its own equipment or it may be done by drilling contractors for a fixed sum or for a price
For purposes of setting forth the various transactions involved in developing oil properties the following notes are based on the assumption that the company uses its own labor and equipment in development work.
OIL PROPERTY LEASES The usual custom of an oil company is to obtain a right in the form of a lease to drill or prospect for oil. The lease in most instances calls for a payment of a royalty of a certain proportionusually one-eighth-of the oil produced.
Leases are acquired in one of the following ways:
(1) From the owner of the fee or lease for a nominal consideration with a provision for a rental to be paid for the time pending commencement of drilling operations.
(2) From the owner of the lease who has acquired it for the purpose of turning over to an incorporated company in consideration for all or a large portion of the capital stock of that company.
It will be obvious that the capitalization of values of oil lands or leases will be merely nominal or large, according to the mode

of acquisition. The capitalized value will have an important bearing on the operations of the company. The effect of such capitalization is discussed briefly later in this article.

operations. In addition to the foregoing there is another important item, viz., that of "proving up” the lease. It is not an uncommon occurrence for oil companies to undertake the drilling of unproductive wells, and the writer wishes to express his opinion as to the propriety of capitalizing expenditures incurred.
When the initial well or wells prove a failure it would appear to be quite correct to capitalize the cost thereof on the theory that such expenditure was necessary to "prove up” the lease. If, however, after the company is successful in bringing in a producer (thereby proving the lease), it should again experience failure, it would appear that the cost of the dry well should be written off as a loss. As an exception to this treatment, initial wells unsuccessful by reason of water trouble, preventing the successful pumping of oil after reaching the oil sand, might justify writing off the cost of such wells as a loss.
When, after a certain time a producing well declines in production to a point at which it is no longer profitable and it is abandoned, the remaining book value of the well should be written off.
FIELD IMPROVEMENTS AND EQUIPMENT Under field improvements and equipment are included all expenditures necessary in building and grading roads; construction of buildings for housing the employees, horses, wagons, automobiles and equipment; boilers and engines; portable drilling equipment; drilling tools and equipment; storage tanks and sump-holes; pipe lines; and any other item of capital assets not strictly applicable to nor permanently a part of any well drilled or being drilled. All these charges are to be absorbed in the production cost as depletion of deposits, discussed at length later in this article.
Well DEVELOPMENT COSTS AND EQUIPMENT The expenditures for well development and equipment are those which are necessary in drilling and completing the well, such as those classified below:
1. Wells requiring use of standard rigs (timber or steel derricks) :
a. Grading-cost of- for location of derrick.

in hole). k. Casing (including freight) used in well. 1. Cement (including freight) used in shutting off water. m. Torpedoes used in shooting. n. Tubing, valves, pump and fittings for pumping oil. o. Superintendence, overhead, etc., and any other expen
diture made in completing well. 2. Wells requiring use of star rigs and portable equipment: a. All items as in previous case, exclusive of cost of der
rick and rigging; but, in place thereof, a proportion of depreciation and repairs of portable equipment, together with any supplies necessary while the rig is
in use on that particular well. Expenditures made on account of non-productive initial wells, such as is discussed under the caption "Leases,” should be transferred from the well development section of accounts to the lease section—the cost of which will be absorbed in the same manner as other lease expenditures.
The well development and equipment expenditures will be amortized over the production of the respective wells, as described later.
The foregoing comment deals with the treatment of the more important items of capital expenditures. It is taken for granted
that the recording of other items will be made according to the generally accepted accounting methods.
OPERATING AND PRODUCTION
1. Depletion of deposits.
3. Operating costs. Probably the most important of the foregoing items is depletion of deposits.
Perhaps the shortest way to explain the method for determining the value of deposits withdrawn from the oil sands will be by use of an illustration.
Assume that a company, (a), acquires title to or lease of 100 acres of oil land, paying therefor, inclusive of recording fees, etc., $10,000.00, (b), expends for rental prior to commencing drilling operations $200.00, (c), expends on field development, such as road-work, acquiring water for drilling purposes, etc., $1,000.00, (d), expends on well development, including derrick, labor and drilling, miscellaneous supplies and expenses, casing, tubing, suction rods and sundry fittings, $8,800.00—in all a total of $20,000.00
Assume further, (a), the number of wells which can be drilled on the lease to be 20 and, (b), the estimated total average production for each well to be 20,000 barrels.
We have, therefore, 20 wells with an estimated total production of 20,000 barrels each, or an estimated total production of 400,000 barrels for the lease. This total of 400,000 barrels represents the estimated oil reserve and, if divided into the sum of $11,200.00, will give 2 4/5 cents a barrel, the proportion of lease and field development expenditure which is to be amortized for each barrel of oil produced.
We have now to determine the amount of well development expenditure to be amortized. We obtain this by dividing the cost of well development by the number of barrels of oil which we estimate this well will produce-$8,800 - 20,000—giving as a result 44 cents a barrel.
When a company is capitalized heavily and the larger portion of the capital stock is paid for the lease, a heavy charge for de
pletion will be made to cost of production, which may and frequently does result in a cost of production greater than the market value of the product.
The question naturally arises as to the basis or method for determining the oil reserve. The following suggestions are for use until the producer is in a position to use his own production figures as a base.
1. In old territory where the logs of other producers are avail
able the estimated oil reserve is determined by the use of the
average production figures of that territory. 2. In new territory, where only a few wells have been drilled
by the companies operating therein, the log or experience of
the average of the producing wells should be used. 3. In new territory or "wild cat" land, there is absolutely no
thing on which to base any estimate until the company has operated its own well for a certain period, and one estimate
is as good as another. After the company has been producing for some months it may use its daily and monthly production figures as its base for determining the estimated total oil reserve; and as a company usually does not make up its production and operating statement until some months after commencement of operations, it generally is not necessary for any computations as to estimated reserves to be made until certain active production figures are available. When the company is producing oil, the scientific method of computing future reserves can be ascertained from Bulletin No. 177, Petroleum Technology 51, issued by the department of the interior, in which the subject is well and sufficiently covered.
In estimating the total oil reserves for a lease in which only one or two wells have been completed it must be borne in mind that the tendency is to a gradual decline in initial production in all wells subsequently drilled; and when estimating the number of well locations in order to determine the total ultimate production, allowance should be made for this probable decline.
The second item entering into production costs is depreciation and upkeep of field equipment. The amount charged for depreciation really consists of two elements, viz:
a. Actual or physical depreciation.
