Document DetailsAqueous Ethanol as an Ice Drilling Fluid
|Authors:||Gosink TA, Koci BR and Kelley JJ|
Aqueous ethyl alcohol (and ethylene glycol) solutions have a substantial history of use in a variety of deep ice drilling projects. This report considers such factors as ice corrosion, penetration, density, viscosity and safety of aqueous ethanol (and of ethylene glycol) as an ice core drilling fluid. The cost and environmental factors for ethanol as a drilling fluid are very good, but aspects such as viscosity and ice corrosion are not.
