to accumulate allows an allotted amount of time to pass so that the water and oil are able to separate once the water level in the reservoir 20 has reached a specific point a water drain valve 23 can release the water into the water drain 21 this drain can allow the water to drain into the existing casing 18 and back into the well referring now to fig1 12 there is shown at least one possible embodiment directed towards the bottom of the bucket 12 engaged to the bottom of the bucket 12 is a fill empty base plate 29 which is freely engaged to sealing plate 28 the sealing plate 28 can move relative to the base plate 29 allowing for the formation of an opening in the bottom of the bucket 12 in response to a properly directed force although fig1 12 and 13 show the fill empty base plate 29 is freely engaged to sealing plate 28 by travel guide 32 and limited in movement by travel stop 31 this inventive concept includes any design in which a member of the bottom of the bucket can be freely moved to form an aperture in the absence of an applied force such as when the bucket 12 is ascending or descending fill empty base plate 29 rests against sealing plate 28 placing the bucket into a closed configuration when a properly applied force is exerted the opening in the bottom of the bucket forms allowing oil to fill the bucket when in a well and allowing oil to drain out when the bucket is lifted.
