SIMULTANEOUS INJECTION AND PRODUCTION WELL SYSTEM

摘要

Systems for simultaneously injecting and producing in a well having multiple zones. One system includes a wellbore providing first perforations extending into a first subterranean formation and second perforations extending into a second subterranean formation, a production tubing having influx ports defined therein and an annulus defined between the wellbore and the production tubing, first and second pairs of wellbore isolation devices arranged about the production tubing and axially straddling the first and second perforations to define first and second formation zones, respectively, a first bypass conduit extending between the first pair of wellbore isolation devices, a second bypass conduit extending between the second pair of wellbore isolation devices, and an injection outlet defined on the first bypass conduit for injecting a portion of the fluid into the first subterranean formation and push hydrocarbons toward the second formation zone to be produced.

1. A well system, comprising:
a wellbore providing one or more first perforations extending into a first subterranean formation and one or more second perforations extending into a second subterranean formation; a production tubing arranged within the wellbore and having one or more influx ports defined therein, an annulus being defined between the wellbore and the production tubing; a first pair of wellbore isolation devices arranged about the production tubing and axially straddling the one or more first perforations to define a first formation zone; a second pair of wellbore isolation devices arranged about the production tubing and axially straddling the one or more second perforations to define a second formation zone; at least one first bypass conduit extending between the first pair of wellbore isolation devices and being configured to allow a fluid within the annulus to axially traverse the first formation zone; at least one second bypass conduit extending between the second pair of wellbore isolation devices and being configured to receive the fluid from the at least one first bypass conduit and allow the fluid to axially traverse the second formation zone; and one or more injection outlets defined on the at least one first bypass conduit and configured to allow a portion of the fluid to be injected into the first subterranean formation to push hydrocarbons toward the second subterranean formation to be drawn into the production tubing at the second formation zone via the one or more influx ports.
