Since core quality rather than hole closure limits the maximum depth capability of a dry hole, we are constructing a modular drill compatible with a dry drill to work in a fluid.

Use of standard industrial equipment such as sludge pumps and well screen keep the cost of this drill relatively low. Because of its robust nature, this drill should also be able to penetrate subglacial material.

Results of the test this summer in Greenland will be presented.

Suggestions for drilling fluids and their relation to personnel, environment, and core quality will be considered.
