Completion apparatus and method for gas lift production
This patent describes a well completion apparatus comprising, in combination: a well packer comprising a mandrel, anchoring and sealing means for anchoring the mandrel in a well casing and sealing, the mandrel having a longitudinal bore communicating with the casing annulus above the packer and below the packer. A method is described for producing a gas-lift well of the type having a casing and a well packer anchored in the casing comprising the steps: running a string of production tubing including a stinger conduit into the well with the production stinger conduit extending through a flow passage bore in the packer, the bore of the stinger conduit defining a flow passage for conducting formation fluid through the packer, and the annulus between the packer bore and the stinger conduit defining an annular flow passage for conducting lift gas from the well casing annulus above the packer into the well casing annulus below the packer; pressurizing the well casing annulus above the packer with lift gas; discharging pressurized lift gas from the well casing annulus above the packer through a surface controllable safety valve into the annulus between the production stinger conduit and the packer bore; conducting lift gas through the packer annulus and discharging it into the lower casing annulus; discharging lift gas from the lower casing annulus into the production tubing through a gas lift valve attached to the production tubing at a location below the fluid level of the well; and, conducting formation fluid from the well through the production stinger conduit.
