December 1, 1918. To His Excellency, the HONORABLE WILLIAM D. STEPHENS,
Governor of California. SIR: I have the honor to transmit herewith Bulletin No. 84 of the State Mining Bureau, being the Third Annual Report of the State Oil and Gas Supervisor.
The law providing for the protection of California oil deposits against water and other damage following improper development methods is an outgrowth of local conditions, and had little or no precedent to follow.
The underlying motive is to gather and arrange facts as to underground conditions and supervise oil field operations, as far as possible, in an advisory manner.
Previous to the enactment of this law, but scant attention had been given to the gathering and comparing of facts, and operations were largely conducted upon theories as to underground conditions. As the theories were usually advanced by men of long experience, the ordinary usage assumed the misnomer of "practical methods."
Very gratifying results have followed three years of educational work, during which time both the department and the oil operators have advanced in knowledge of natural laws governing underground conditions.
As was to be expected in such work, a few operators have not readily adopted suggested changes in operations, and some do not yet realize their responsibility in protecting the oil fields, in which the public is vitally interested. Some changes in the law, therefore, will be necessary in order to make it thoroughly effective. Such changes will not affect individuals or corporations who are more interested in the spirit rather than the letter of the law. Respectfully submitted.
MR. FLETCHER HAMILTON,
State Mineralogist. SIR: In transmitting the Third Annual Report of the work of the Department of Petroleum and Gas, I believe it may be well to call attention to the fact that the usefulness of the department to the public requires absolute impartiality in dealing with the various producers, both large and small. It is a pleasure to record that the department has been given a free hand to discharge its duty. Respectfully submitted.
R. P. MCLAUGHLIN, State Oil and Gas Supervisor.
