Well Cuttings & Core Inventory

The Arkansas Geological Survey (AGS) is the curator for the Norman F. Williams Well Sample Library and maintains well cuttings and core samples as a permanent record of rock strata that have been penetrated by wells drilled in Arkansas. The well samples are used by state and federal agencies, academia, industry, and the general public for geological research. There is no charge for an onsite examination of the cuttings and core. No sample materials are permitted to leave the premises at any time for inspection. The AGS has the discretion to permit or deny permission for the destructive analysis of the well samples and this determination will be made on a case-by-case basis based on the quantity of material that is present and the historical and scientific value of the sample. Under no circumstances will there be permission to consume or alter well samples if insufficient material is determined to be present by the AGS. Upon completion of any examination or analysis, the thin sections, polished sections, etc. become the property of the AGS, along with any raw data, such as chemical analyses, written descriptions, plan maps of well locations, cross-sections etc. All materials and information associated with the samples will be sent to the AGS in a mutually agreed upon time frame.

The Arkansas Geological Survey's Well Sample Library is contained in a building 85 feet wide and 260 feet long. This building has 18,125 square feet of floor space divided as follows: AGS Learning Center, 5,465 sqare feet; AGS Well Sample Library, 9,540 square feet.

The Well Sample Library presently contains (1) approximately 10,000,000 feet of rock cuttings from 2,500 oil and gas test holes and water wells drilled in Arkansas; (2) 2,500 feet of core from 50 oil and gas tests mainly in south Arkansas; (3) 300,000 feet of core from 1,500 mineral exploration tests in the Ozark and Ouachita Mountains of Arkansas.

An examination room is provided in the sample library. The examination room is equipped with microscopes, lamps, examination tables, core tables, chairs, wash sinks, maps, telephone, drinking fountain, heating and air conditioning.

This earthquake archive list was made from a selection of seismic events that have occurred from 1699 to present in Arkansas. The seismic data have been cited from publications of the Center for Earthquake Research and Information (CERI) at the University of Memphis, the Department of Earth and Atmospheric Sciences at Saint Louis University, the United States Geological Survey (USGS), the Eastern Section of the Seismological Society of America and the University of Arkansas at Little Rock. We extend our appreciation to John David McFarland (Arkansas Geological Survey) for compiling the original earthquake database.
