Maryland Geological Survey Drill Cutting Collection


The Maryland Geological Survey (MGS) Drill Cutting Collection includes rock cuttings of all types as well as unconsolidated Coastal Plain sediment cuttings. It consists of approximately 5,200 boxes (15.5 x 5.5 x 3.5"), each containing 20-50 envelopes, bags or vials of cuttings from drilling sites throughout Maryland.

As of August 2018, approximately 424 boxes containing approximately 8,579 envelopes of cuttings have been geospatially linked to borehole locations. These are included in the interactive map of the MGS Drill Cutting Collection and data table (see links below). An additional 121 boxes have been catalogued, and partially cross referenced to boreholes. All of these 545 boxes and over 10,900 envelopes have been relabeled and repackaged.

The Drill Cuttings Collection is now primarily stored in the MGS Core (and Cuttings) Library in the basement of MGS’s Kenneth M. Weaver building. Due to space constraints, some cuttings are stored in the basement of the Weaver Annex building. The majority of the drill cuttings were collected by well drillers and MGS geoscientists. Some sets of cuttings were donated to MGS by other researchers, other government agencies, and geotechnical or environmental consultants. Many of the wells and/or boreholes from which the cuttings originated are referenced in published MGS reports.

As part of the inventory process, a database was created to help capture information about each set of cuttings, including, but not limited to:
