Abstract
An apparatus (10) and method for obtaining oil and water saturation data from subterranean formations includes a drill bit (12) for boring a well core (26) containing the fluids. A core-catcher bowl (18) guides the well core (26) in the apparatus (10). An outer barrel (14) is attached to the drill bit (12) and contains the core-catcher (18). An inner liner (20) positioned in the outer barrel (14) receives the well core (26). An oil absorbent sponge-like member (22) is contained in the inner liner (20) with a diameter (24) for receiving the well core (26). The oil absorbent sponge-like member (22) absorbs the fluids contained in the well core (26).

Apparatus for recovery of subterranean fluid comprising:
- means for boring a well core containing the subterranean fluid;
- container means associated with said boring means for containing said well core;
- and
- an oil and water absorbent member having a predetermined configuration disposed in said container means and proximately positioned adjacent said well core, said absorbent member having sufficient permeability and porosity for absorbing the subterranean fluid as the subterranean fluid emanates from said well core and for storing the absorbed subterranean fluid for later retrieval.
Apparatus for recovery of subterranean fluid comprising:
- means for boring a well core containing the subterranean fluid;
- container means associated with said boring means for containing said well core;
- and
- a hollow cylinder dimensioned to fit in said container means, said hollow cylinder comprising an oil and water absorbent sponge-like member and proximately positioned said well core for absorbing and storing subterranean fluid.
