Compiled by R. A. Bieberman, 1970, 10 pp. Supplemet to circulars 22, 30, 45, 61, 88, and Bulletin 73.

List of samples from approximately 2,000 wells added to NM Bureau of Mines and Mineral Resources Sample Library since June 1966. Collection of samples from oil and gas well tests in NM by the NM Bureau of Mines and Minerals Resources commenced shortly after its establishment in 1927. Through the years the collection has grown until, at present, samples from over 8,400 wells from all parts of New Mexico are included. Samples from cuttings and cores in the collection are indexed and readily available for study. The collection provides a state-wide record of subsurface stratigraphy and is a permanent repository for this valuable geological materials. Though only a small proportion of the field wells are represented, every effort has been made to secure samples from wildcat tests. New accessions are being made constantly as drilling progresses. The library will have increasing value as the search for liquid and gaseous fuels becomes more intensive.
