Abstract:
A downhole isolation tool for insertion in a wellbore and seated engagement to a downhole assembly, for allowing, when a sliding sleeve thereof is slidably positioned in a first position and when coupled to a lower end of said pump apparatus, fluids within a hydrocarbon formation to be drawn through such tool and allowed to pass to the pump apparatus for pumping uphole, and when such sliding sleeve is positioned in a second position and decoupled from said lower end of the pump assembly, for preventing said fluids from passing therethrough and uphole.

Claim (Index 16):
A downhole isolation tool for insertion in a wellbore, which when configured to a first position allows fluids within a hydrocarbon formation to be drawn through said tool, and when configured to a second position prevents said fluids from passing therethrough and up the wellbore, comprising:\n (A) an elongate sliding sleeve having an upper and lower end and an elongate cavity therewithin separated into an upper cavity and a lower cavity by a seal member that prevents fluid communication between said upper and lower cavity, further having:\n (i) a releasable latch means at said upper end thereof, constructed and arranged for releasibly coupling to a pump apparatus; \n (ii) an opening at said lower end to allow fluid communication between said wellbore and said lower cavity; \n (iii) a first aperture means, situated proximate said upper end, in fluid communication with said upper cavity; \n (iv) a second aperture means, situated above said seal member and longitudinally separated from said first aperture means, likewise in fluid communication with said upper cavity; \n (v) a third aperture means, situated below said seal member and in fluid communication with said lower cavity; and \n (B) an elongate cylindrical seal sub, having an upper and lower end and, along a longitudinal axis of said seal sub, a bore therethrough for slidably receiving therewithin said sliding sleeve and allowing slidable movement thereof from said first position to said second position, further having:\n (i) a bypass channel, situated along said bore at a bore surface distal to said upper and lower ends of said seal sub, and bounded by the sidewall of the seal sub, thereby preventing fluid communication exterior to the seal sub from the bypass channel; and \n (ii) a seating means capable of sealingly engaging said seal sub to an assembly in the wellbore; \n wherein when said downhole tool is configured in said first position, said sliding sleeve is positioned within said bore so that said second and third aperture means, and said seal member, are aligned with said bypass channel in said seal sub to allow communication of fluids from said lower cavity to said upper cavity of said sliding sleeve via said bypass channel; and wherein when said sliding sleeve is slidably moved upwardly so as to thereby be configured in said second position, said first aperture and said seal member are positioned above said bypass channel to thereby prevent communication of fluids from said lower cavity to said upper cavity of said sliding sleeve.
