Abstract
A method includes in a single trip running a completion system having an internal bore into a wellbore that penetrates a formation zone, the completion system having an upper completion connected to a lower completion, setting an isolation packer forming a barrier above the formation zone, displacing the annulus fluid above the set isolation packer and then setting an upper packer thereby providing a completion barrier above the set isolation packer. The annulus fluid may be displaced prior to setting an upper completion packer.
Claims20
A single trip completion system, comprising:
- an upper completion and a lower completion connected at a coupler to be run into a wellbore as a unit in a single trip;
- the lower completion comprising:
- an isolation packer;
- a fluid communication valve located above the isolation packer to control communication between a completion bore and an annulus of the wellbore;
- and
- an upper packer located above the fluid communication valve.
A method, comprising:
- in a single trip running a completion system having an internal bore into a wellbore that penetrates a formation zone, the completion system comprising an upper completion connected to a lower completion;
- setting an isolation packer forming a barrier above the formation zone in an annulus between the lower completion and the wellbore;
- displacing an annulus fluid above the set isolation packer;
- and
- after the displacing, setting an upper packer thereby providing a completion barrier above the isolation packer.
A method, comprising:
- in a single trip running a completion system having an internal bore into a wellbore penetrating a formation zone, the completion system comprising an upper completion connected at a coupler to a lower completion, wherein the lower completion comprises an isolation packer, a fluid communication valve located above the isolation packer operable to control fluid communication between the internal bore and an annulus of the wellbore, and an upper packer located above the fluid communication valve;
- setting the isolation packer above the formation zone;
- displacing an annulus fluid above the set isolation packer in response to circulating a fluid from the internal bore through the fluid communication valve;
- and
- after the displacing setting the upper packer thereby providing a completion barrier above the isolation packer.
