Abstract
A main well bore is drilled. The main well bore is completed and stimulated. The main well bore is sealed. A lateral well bore is drilled off the main well bore. A junction that allows communication with the lateral well bore and that connects the main well bore is inserted. The lateral well bore is stimulated through the junction. The main well bore is unsealed, allowing comingled flow from the main bore and the lateral bore.
Claims13
A method for acid stimulation of a multilateral well, comprising:
- drilling a main well bore;
- completing and stimulating the main well bore;
- sealing the completed and stimulated main well bore;
- drilling a lateral well bore off the sealed completed and stimulated main well bore;
- inserting a junction that allows mechanical access and hydraulic communication with the lateral well bore and that allows communication with the main well bore;
- stimulating the lateral well bore without intervention;
- and
- unsealing the main well bore, allowing comingled flow from the main well bore and the lateral well bore.
5 more elements
A system for producing hydrocarbons from a multilateral well, comprising:
- a main well bore extending from a well origin;
- a lateral well bore branching from the main well bore, wherein the lateral bore is stimulatable without intervention;
- a main bore completion positioned in a main well bore producing zone in the main well bore;
- a lateral completion installed in a lateral producing zone in the lateral well bore;
- a junction having:
- a first leg positioned in the lateral well bore between the well origin and the lateral completion,
- a second leg positioned in the main well bore between the well origin and the main bore completion, and
- a coupling where the first leg and the second leg are mechanically joined
- a fluid loss device positioned between the main bore completion and the junction, wherein the fluid loss device has an open position, in which fluid is allowed to flow therethrough, and a closed position in which fluid flow is not allowed, and wherein the fluid loss device is actuatable from the closed position to the open position.
