Visual Context Awareness via Wearable Computing

A method of and apparatus for stabilizing oil well cores taken within rubber sleeve core barrels is provided wherein an unconsolidated and friable columnar mass of earth may be handled without altering the characteristics of its physical structure. A housing is therein provided for receiving a conventional rubber sleeved core sample from a vertically suspended core barrel inside a drilling rig. The housing is adapted for the positioning of the ensleeved core therein and the circulation therearound of a subfreezing mass for the freezing and solidification of the core fluids contained therethrough. Freezing of the core fluids immobilizes rock grains and the like, stabilizing the core sample for handling and second stage stabilization through rigid encasement in a casting medium. The casted core may then be handled in a conventional manner during transportation for subsequent analysis in its original condition.
