Abstract

A wellbore completion is configured for multiple forms of artificial lift. A downhole assembly on production tubing defines a production port communicating a throughbore with the wellbore annulus. A bypass, such as a snorkel or riser tube, on the assembly also communicates the throughbore between the packer and the production port with the annulus. A packer on the assembly seals in the annulus downhole of the production port and bypass. The assembly can then be configured for any selected artificial lift. To do this, at least one isolation (a sleeve insert, a sliding sleeve, a check valve, or a rupture disk) selectively prevents/allows communication via one or both of the production port and the bypass as needed. Additionally, removable lift equipment, including jet pump, gas lift valve, plunger assembly, rod pump, piston pump, or standing valve, is selectively inserted into the assembly's throughbore as needed.

Dependent claims

A completion apparatus useable for artificial lift with production tubing in a wellbore, the apparatus comprising:

a downhole assembly disposed on the production tubing in the wellbore and defining a throughbore, the downhole assembly defining a production port communicating the throughbore with an annulus of the wellbore;
a packer disposed on the downhole assembly and sealing the annulus downhole of the production port;
a bypass disposed on the downhole assembly, the bypass communicating with the throughbore between the packer and the production port and communicating with the annulus;
at least one isolation disposed on the downhole assembly and being selectively configured in at least two configurations, the at least two configurations being selected from:
(i) a first configuration configured to prevent the communication via the bypass and allow the communication via the production port, and (ii) a second configuration configured to allow communication via both the production port and the bypass;
and
at least two types of lift equipment selectively insertable into the throughbore in place of one another and configuring the downhole assembly for at least two forms of artificial lift, a first of the at least two forms being different from a second of the at least two forms.

A method for completing a wellbore for multiple forms of artificial lift, the method comprising:

disposing a downhole assembly on production tubing in the wellbore, the downhole assembly defining a throughbore and defining a production port communicating the throughbore with an annulus of the wellbore, the downhole assembly having a bypass communicating with the throughbore between the packer and the production port and communicating with the annulus;
sealing a packer on the downhole assembly in the annulus downhole of the production port;
and
configuring the downhole assembly for at least two of the multiple forms of artificial lift by:
selectively configuring communication with at least one isolation in at least two configurations selected from:
a first configuration preventing the communication via the bypass and allowing the communication via the production port, and a second configuration allowing communication via both the production port and the bypass;
and
selectively inserting at least two types of lift equipment into the throughbore in place of one another and configured for the selected at least two forms of artificial lift.
