ABSTRACT:
A temporary guide base for use in drilling underwater wells in areas where the bottom conditions are unstable comprises a plurality of boxes opened at the bottom having a centrally disposed hole for casing, and vent means to allow retrieval of the guide bases without causing a suction effect, the guide bases being open to the sea on the bottom to fill the sea water but float in the mud on the bottom.
