CA 2269710

A system of reciprocating bottom hole sucker rod pumps, situated in an oil well, to produce an oil rich stream to surface and inject a water stream to a same wellbore disposal zone. Two pumps vertically in tandem are actuated by a single sucker rod string. Separate intakes for each pump are situated so as to allow for gravity to segregate oil and water in the wellbore before reaching the intakes. Both streams are produced out of the pumps on the upstroke. Injection of the water stream is facilitated by an outer housing around the bottom pump to redirect flow to a disposal zone.
