1156 Subsurface Geologic Methods 



are used in conjunction with the cuttings as an aid in the interpretation 

 of the stratigraphic sequence. 



Library: In addition to the sample processing and analysis services, 

 a library is maintained which contains cuttings from many tests drilled 

 in all of the Rocky Mountain states. These are rented on a cost per set 

 basis and are utilized by those geologists that do not have space for 

 library storage or whose other duties confine them to ofi&ces so that they 

 cannot study samples at depositories lacking shipping facilities. 



Arkansas Geological Survey 

 Little Rock, Arkansas 



The well-sample library of the Arkansas Geological Society has only 

 recently been organized. The principal interest is in wells of the Gulf 

 Coastal Plain area. Most of the samples now available are from wells in 

 eastern and northeastern Arkansas. Most of the cuts of samples have been 

 contributed by the companies. In certain key wells in areas of particular 

 interest the office has supplied geologic services in return for sample sets. 



The laboratory has facilities for working and drying samples and 

 a storage room. An assistant is available for processing the samples. 



New Mexico Bureau of Mines and Mineral Resources 

 Socorro, New Mexico 



The New Mexico Bureau of Mines and Mineral Resources lists wells 

 by township, range, section, operator, and lease. Pool wells in south- 

 eastern New Mexico are listed only by field, county, and number of sample 

 sets from each pool. Additional information on these pool wells will be 

 given upon request. 



All samples are available for examination at any time in Socorro. 

 They may also be borrowed by reliable companies or individual geolo- 

 gists with the understanding that they will not be cut, washed, or damaged 

 in any way. In fairness to all, the bureau requests that no set of samples 

 be kept longer than thirty days at any one time.
