REPORT OF THE DIRECTOR, 1922 19 
In order that the best possible results may be obtained in the sur- 
_ vey of the oil fields, a structure map should be made of the main 
oil pools. Such a map would be based largely on the logs of the 
numerous wells already drilled. Unfortunately few bench markings 
have been determined so that in addition to the well logs the elevation 
of the various wells should be obtained. Such a map would indi- 
cate the depth necessary to drill in order to reach a certain sand. 
. Whenever possible, the logs of the wild cat wells should be obtained. 
In many cases these wells were abandoned before the producing 
sand was reached and it is believed that certain areas which have 
been regarded as nonproductive, may yield oil upon deeper drilling. 
Although special studies are being made of water for the use of 
restored pressure, other agents which can create the necessary driv- 
ing force are being given attention. These include the use of 
natural gas and air, as well as several new methods. However desir- 
able the use of methods other than water may appear from the point 
of conservation, it seems likely that the water drive having become 
so well established will not easily be displaced by other methods 
unless some greatly improved method is discovered. It is to be 
hoped that before the field is committed entirely to the water drive, 
a number of deep tests be made in order to determine the possibility 
of producing oil or gas-bearing sand below the sands that are to be 
watered out. If this is done, it will save considerable costs in casing 
off the watered-out sand should at any future time a supply of oil 
or gas be found at a depth greater than the present producing sands.

Museum expansion. The last report of the Director gave some 
account of plans and designs for a State Museum building which 
would not only relieve the present congested condition of the scien- 
tific museum but give opportunity to develop the scope of the general 
museum as outlined in the statute of the State, but for which the 
State has never made financial provision. Reference was therein 
made to the fact that the proposition for such new State Museum 
building had received favorable consideration by the State Roosevelt 
Memorial Commission. The published report of that commission of 
which the chairman is Prof. Henry Fairfield Osborn, president of 
the American Museum of Natural History in New York City, inti- 
mates a purpose to commemorate the outdoor aspects of Colonel 
Roosevelt’s career, his love of nature, of wild life, his enthusiastic 
espousal of, and deliverances upon the themes of natural science,
