Abstract

An apparatus (11a) for introduction of gas into a wellbore containing production tubing (12a) is provided. The apparatus consists of a conduit (30a) for location at least partly within the production tubing (12a), an inlet (32a) providing communication between the conduit (30a) and a wellbore annulus, and an outlet (34a) providing communication between the conduit and a reservoir (16). The apparatus therefore allows gas to be introduced into reservoir fluids at a distance from introduction of gas into the production tubing, so increasing the effective depth of gas introduction. A method of gas introduction is also described.

(57) An apparatus (11a) for introduction of gas into a wellbore containing
production tubing (12a) is provided.
The apparatus consists of a conduit (30a) for location at least partly within the production tubing (12a), an inlet (32a) providing communication between the conduit (30a) and a wellbore annulus, and an outlet (34a) providing communication between the conduit and a reservoir (16. The apparatus therefore allows gas to be introduced into reservoir fluids at a distance from introduction of gas into the production tubing, so increasing
the effective depth of gas introduction. A method of gas introduction is also described.
