Abstract
Systems and methods for gas lift in the main bore and lateral legs of a multilateral well. The systems and methods can allow for gas lift below the junction of a multilateral well.
Claims20
A bypass packer configured for use in a gas lift system in a multilateral well, the bypass packer comprising:
- a through bore configured to receive tubing, the tubing configured to carry produced oil to the surface in use;
- and
- the bypass packer configured to receive gas from an annulus between the tubing and a well casing and transfer the gas into a gas tube extending from the bypass packer in use.

A multilateral gas lift system comprising:
- a main production tubing configured to transport produced oil flow uphole;
- a main bore assembly comprising a main bore tubing;
- a lateral bore assembly comprising a lateral bore tubing;
- a Y-block configured to combine produced oil flow from the main bore tubing and the lateral bore tubing into the main production tubing;
- and
- a gas lift system configured to allow for gas lift in either or both of the main bore and the lateral bore.
3 more elements
A gas lift method comprising:
- injecting gas into an annulus between a casing and a tubing of a multilateral well such that the gas flows into both an annulus of a main bore of the multilateral well and an annulus of at least one lateral leg of the multilateral well;
- and
- releasing the gas into production tubing of the main bore and/or into production tubing of the at least one lateral leg.
