The heart of the Adaptable Tool is actu- ally a plunger pump similar to that used for pumping oil wells, except that "tailpipe" and a series of check valves are run below the pump. By reciprocating the tubing at the surface, the pump vigorously pulls fluid and debris (sand, scale, cement, junk, etc.) up into the tailpipe, where it is held by the check valves.

The Adaptable Tool is not prone to get- ting stuck in the hole, as are other casing cleanout tools, for several reasons:

1) The Tool is continuously reciprocat- ed, which keeps the casing walls clean and prevents the Tool from tun- neling into the sand and getting stuck, and;
