Photocopies of records such as well logs, petroleum exploration maps, and pool maps may be obtained at nominal cost. Companies and individuals who wish to donate cuttings, logs, or other information to the Subsurface Library are asked to call or write. Donations are always welcome and most of our materials have come from donations of generous companies and individuals. The purpose of the Core Library is to have available for study representative cores from rock formations in different parts of New Mexico. The Core Library consists of five warehouses, a processing area, and tables for examining core.
Microscopes are available for visitor's use.
An interactive GIS map shows approximate locations of these drillholes and provides summary information. All sampling must be approved beforehand. In addition to the cores, location information, geophysical logs, drillers' logs, and other material are available for many holes. More than 4,000 cores donated by over 100 different companies and other organizations are ready for examination. The age of units in these cores ranges from Precambrian to Holocene.
