zontal boreholes, which may be advantageous for economic rea-
sons as well as necessary when surface obstacles prevent direct access. The problem is compli-
cated further by the fact that it is desirable or required by environ-
mental regulations, in some cases, that no drilling fluids be used to stabilize the boreholes.

Accomplishments

This effort has focused on labora-
tory and bench-scale studies to evaluate the feasibility of future drilling demonstrations. Because of the pending closeout of this ID, the demonstration of this techn-
ology is being pursued at other sites.

Collaboration/Technology Transfer

This technology is being develop-
ed by the University of California at Berkeley. There has to date been no collaboration with indus-
try on this project, but a number
of potential partners do exist.
