Claim:
An oil extraction system for the removal of oil from an oil well, the system comprising: an upper extraction unit; an extraction container; and a sealing member pivotally engaged to the extraction container; the upper extraction unit having a lifting mechanism connected to the extraction container and capable of lowering the extraction container into and lifting the extraction container out of an oil well; the extraction container having a top, a bottom, defining a volume capable of storing fluid, and constructed and arranged to have an open configuration and a closed configuration; the sealing member regulating the flow of fluids along the outside of the container between the top and the bottom of the container, the oil extraction system further comprising a side, the sealing member can flexibly pivot relative to the side, the sealing member being capable of pivotably transitioning between a more vertical orientation and a more horizontal orientation, the sealing member allowing fluids to pass more freely along the outside of the container when the sealing member is in the more vertical orientation than when the sealing member is in the more horizontal orientation.
