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 ).
