SOURCES OF WELL INFORMATION 



Well Sample Library, Colorado School cf Mines 

 Golden, Colorado 



The well-sample library at the Colorado School of Mines was origin- 

 ally under the auspices of the Board of Industrial Development and 

 Research of the State of Colorado. It is now operated as a function of the 

 school. 



The library now has on file samples from 1,531 wells. The geographic 

 distribution of these wells is as follows: 



Arizona 3 Nebraska 12 



California 3 New Mexico 157 



Canada 16 North Dakota 5 



Colorado 462 Oklahoma 16 



Idaho 6 South Dakota 8 



Kansas 100 Texas 74 



Louisiana 1 Utah 56 



Mexico 1 Washington 1 



Montana 233 Wyoming 377 



Samples from the wells are vialed, systematically filed, and card 

 indexed. More than 225,000 samples are involved in the collection. 



Several well lists have been published and may be obtained free 

 upon request. In addition to these lists an issue of the Quarterly of the 

 Colorado School of Mines entitled "Selected Well Logs of Colorado" by 

 Barb ^ is available from the Department of Publications of the school. 



It is a violation of policy for the samples to leave the depository 

 once they have been vialed and cataloged. Space in Berthoud Hall, the 

 geology building, is available for those interested in sample examina- 

 tion. Microscope, lamp, and other equipment must be supplied by the 

 examiner. 



In addition to ditch-cutting samples, electric logs from Colorado, 

 Oklahoma, Kansas, and Texas wells are available for study. 



Paleontological Laboratory 

 Midland, Texas 



The primary function of the Paleontological Laboratory is to furnish 

 paleontologic data to oil operators who desire more detailed information 

 for their stratigraphic work. Emphasis is placed on the identification
