Abstract
A zone isolation assembly (22) for a subsurface well (12) that includes a riser pipe (30) having a fluid zone includes a movable docking receiver (48), a fluid inlet structure (31) and a sealer (56). The docking receiver (48) is adapted to be positioned within the riser pipe (30). The fluid inlet structure (31) is coupled to the docking receiver (48). The fluid inlet structure (31) allows a first fluid from the fluid zone into the fluid inlet structure (31). The sealer (56) is coupled to the docking receiver (48). The sealer (56) selectively forms a seal with the riser pipe (30) to divide the fluid zone into a first zone (26) and a second zone (28) when the sealer (56) is in a first position. In the first position, the first zone (26) is not in fluid communication with the second zone (28).
