Ohio Geological Sample Repository

core sample image
The main function of the Ohio Geological Sample Repository is to preserve and provide public access to the core and sample collections housed at the H. R. Collins Laboratory. The collections are used by scientists, academicians, and other researchers to conduct petrologic, mineralogic, and other detailed studies of Ohio's geologic natural resources.

With support from the U.S. Geological Survey’s National Geological and Geophysical Data Preservation Program, the Division of Geological Survey has compiled inventories and generated databases for its collections. Metadata is available to the public for all inventoried collections. Learn more about the facility and its collections below.

Facility Information

Collections

The repository core collection consists of nearly 900 boreholes—totaling over 300,000 feet—drilled in Ohio, Kentucky, and West Virginia. Core locations throughout Ohio are available on the oil and gas interactive map.

The repository well sample collection consists of sample suites from over 3,100 wells, duplicate sample suites from over 1,100 wells, and well cutting sample and lithologic strip logs from over 1,700 bore holes.

Additional collections include*:

  • Aerial photographs flown from 1950 to 1979.
  • Environmental impact statements.
  • Geochemical records of data from brine, carbonate, and coal samples.
  • Lithology strip logs for oil and gas well boreholes, cores, and measured sections.
  • Myron T. Sturgeon Pennsylvanian hand sample collection from Ohio.
  • Oil samples.
  • Sand and gravel resource investigations.
  • Seismogram tracings collected between 1905 and 1992.
  • Side wall core and core plugs.
  • Thin sections.
  • Unconsolidated Cenozoic-age sediment samples.
  • Unpublished manuscripts, field maps, and field notes.

*NOTE: Some collections may be housed at the Division of Geological Survey main office in Columbus; always contact the Division before visiting to confirm the accessibility of research materials.

Compensation for Services

Lab Use and Services
The Division of Geological Survey charges nominal rates for the significant effort to pull and reshelve samples, maintain core cutting/sampling equipment, and other tasks related to accessing and preserving the core and cuttings samples at the H. R. Collins Laboratory.

Those desiring to sample core and cuttings must abide by the Core & Cuttings Use Policy (see below). Parties wishing to use the facility or sample rock materials can obtain an estimate of cost by emailing us with their desired use or sampling program at Collins.Lab@dnr.state.oh.us.

Compensation in Appreciation of Services
The Division of Geological Survey accepts credit card (Visa or MasterCard only) payments for services rendered at the H. R. Collins Laboratory. Payments may be made by calling the Geologic Records Center at (614) 265-6576.

Please note:

  • All material handling and sampling will be performed by the Division of Geological Survey staff; sampling will be performed by Division staff, unless otherwise agreed to prior to visit.
  • All sampling of materials must adhere to the Core & Cuttings Use Policy (see below).

Student Rates
The Division of Geological Survey encourages the use of the H. R. Collins Lab for academic research, and we are supportive of self-funded students. Accordingly, we may discount the usage and/or sampling rates charged to students by up to 50%, depending on the research topic and the size and nature of the request. For a request to be considered, we will require a detailed scope of work (title or topic of research; the core, samples, or collections that need accessed, including the amount (footage); amount of sampling to be performed, etc.).

Authority ORC 1505.02 • Effective August 2013

Repository Core & Cuttings Use Policy

The Division of Geological Survey desires to make its core samples readily accessible for legitimate and professional scientific research by qualified practicing geologists, trained geotechnical individuals, consulting firms, graduate geology students, and university geology faculty. At the same time, the Division of Geological Survey has a determined responsibility to permanently preserve a minimum of one half (½) of the original diameter for each core held at the Sample Repository. In order to achieve a balance of these goals, we have prepared this Core and Cuttings Use Policy.

The H. R. Collins Laboratory is available for use by appointment only and during normal business hours (8:00 a.m. to 4:30 p.m., M–F, excluding state holidays). Access is given on a first-come, first-served basis unless special permission is given by the Division Chief. Those wishing to use the facility should review this core and cuttings sample use policy and complete the Acceptance Form (PDF) for use of laboratory facilities and core/sample repository. To schedule a visit, please send a brief e-mail to Collins.Lab@dnr.state.oh.us describing the project, cores to be examined, duration of study, anticipated reports or publications, mailing and emailing addresses, and telephone numbers of each investigator. Completed acceptance forms should be emailed to Collins.Lab@dnr.state.oh.us prior to or submitted upon arrival of the scheduled visit.

Core and cuttings must be examined at the H. R. Collins Laboratory. For core, when macroscopic sample examination is not sufficient, a few thin-section billets may be provided as long as the minimum one half (½) core is preserved. For cuttings, if microscopic sample examination is not sufficient, material for a few grain-mount thin-sections may be provided as long as we determine that sufficient sample is available. A formal request must be submitted if many samples are requested or destructive testing is involved. The following requirements also apply:

  • The request must be specific as to which cores are required and the amount of sampling necessary.
    • Sampling of cores must be kept to the minimum (i.e., generally not more than a quarter (1/4) core for cores 2 inches or less in diameter nor more than an eighth (1/8) core for cores greater than 2 inches in diameter).
    • For cuttings, we will determine if duplicate sets of cuttings exist from the study area. Sampling will be from duplicate sets of cuttings, if available, and sampling should be kept to a minimum.
  • Cores remain the property of the Division of Geological Survey. Thin sections, polished sections, sample residues, and other items made from sampled portions of the cores shall be returned at the conclusion of the project to become part of the Division of Geological Survey's permanent library for the benefit of the public. All thin sections, billets, and sample residues should be clearly labeled with core number and footage. Failure to furnish these materials will result in suspension or revocation of privileges. Confidentiality may be granted upon request.
  • Final sampling arrangements shall be set forth in an e-mail from the Facility Coordinator and acknowledged by the borrower.
  • Copies of core sample descriptions, data, analytical results, unpublished and published reports, theses and dissertations, and any other data must be supplied to the Division of Geological Survey. All data should be made public through independent publication and/or placed on open file at the Division of Geological Survey. Under some circumstances, information may be placed in a confidential status under the authority of the Division Chief (ORC §1505.03). Failure to furnish these materials will result in suspension or revocation of privileges.
  • The Division of Geological Survey must be properly acknowledged in any unpublished report or formal publication resulting from the inspection and/or analysis of samples it holds.

Sample Donations

The H. R. Collins Laboratory gladly accepts donations of rock core and other geologic materials and data from Ohio and nearby surroundings. Space is limited, so unfortunately we cannot accept all donations offered. Whether we accept a donation of core depends on its condition, the completeness of the accompanying documentation, and whether the core augments or merely duplicates data already on hand. Donated materials become the property of the Division of Geological Survey and will be made available for public use or public display. A confidentiality agreement for up to one (1) year from donation date may be granted on a case-by-case basis.
