Abstract
A system and method of plugging a well bore includes intersecting a portion of a well with a subterranean cavern. A portion of the well may be isolated to prevent accumulation of reservoir fluids in the subterranean cavern by, for example, inserting a packer in the well to form a seal. A sealing material may be pumped into and allowed of solidify in the portion of the well to form a partition between the subterranean cavern and the remainder of the well. The formed partition permits continued production from the well and continued mining in the subterranean cavern.
Claims24
A method of plugging a well bore comprising:
- intersecting the well bore and a subterranean mine;
- and
- depositing a seal through the intersection of the well bore and subterranean mine to isolate a portion of the well bore.
A method comprising:
- forming a vacuum in the well;
- depositing a seal through an intersection of the well and subterranean mine to isolate a portion of the well from the subterranean mine;
- and
- producing a fluid from the well.
A system for isolating a portion of a well bore comprising:
- a packer disposed in the portion of the well bore;
- a well bore segment formed between the packer and an intersection of the well bore and a subterranean mine;
- an casing extending into a length of the well bore segment from the subterranean mine;
- an end piece coupled to the casing at a sub-surface end thereof, the end piece comprising an orifice;
- and
- a tubing string operable to inject a sealing material from the subterranean and into the well bore segment.
