If the pressure on the gravel pack packer 32 as detected based on measurements from sensors 68 and 60 reaches a predetermined level, then steps in real or near real time may be taken to reduce the pressure on the packer 32.

Other examples of other components where differential pressure measurements may be taken include inside and outside the service tool 20 and across the fluid loss control seals 42 and 43.
  • the sand control system 10 may include a formation isolation valve, and pressure sensors may sense pressures above and below the valve, in accordance with some embodiments of the invention.
  • the sensor 68 may be positioned below the circulating port 40 so that pressure measurements can be made during the gravel packing operation.

In addition, pressure measurements may be taken during swabbing. While the service tool 20 is adjacent the gravel pack packer 32, the pressure below the packer 32 decreases when the service tool 20 is moved upwards in relation to the packer 32. The sensor 64 or the sensor 68 may be used to monitor the pressure of the fluid within the annulus 34 to ensure that the observed pressure does not fall below the fluid pressure within the reservoir for the wellbore 14.

  • the sensor 64 may be monitored to ensure that the fluid pressure within the annulus 34 does not exceed the reservoir fracture pressure during a gravel operation. If the sensor 64 records such an elevated pressure reading, then the rate of the slurry flow may be reduced or chokes at the Earth surface of the well may be fully or partially opened. For fracturing treatments, the sensor 64 may also be monitored to ensure that fluid pressure within the annulus 34 does not fall below the reservoir fracture pressure. If the pressure sensor 64 records a measurement falling below a predetermined pressure level, then the pressure may be increased within the annulus 34 by increasing flow rate or chokes at the surface or in the well may be fully or partially closed.
  • the pressure sensors may be used to monitor other parameters, in accordance with many potential embodiments of the invention.
  • pressure may be monitored across downhole components. Therefore, if the measured pressure is higher than a rating (a burst or collapse rating, as examples) for the component, then the surface pump rate may be decreased or a surface choke may be opened to maintain the component within the appropriate operating envelope.
  • the differential pressure across the gravel pack packer 32 may also be monitored. In this manner, the sensor 68 may be used as well as sensor on top of the wash pipe 22 to ensure that the collapse pressure of the blank pipe ensure is not exceeded.
  • the pressure sensors may be used to observed friction pressures throughout the system. For example, packing mechanisms, fluid changes, screen plugging, etc. may be monitored and compared with expected trends.

  • fluid losses occur when the fluid return rate is less than a fluid pump rate at the Earth surface.

As described above, these rate measurements may be acquired directly or may be acquired indirectly using pressure or temperature measurements. In general, losses at the heel of the well may be far more detrimental to the sand control job than losses at the toe, so the measured rate measurements permit an informed decision to be made.

In an open hole water packing treatment, such a scenario may terminate the job due to screenout at the cross-over assembly 25.

  • it is relatively difficult to observe that hole has formed in the sand control section as it is usually discovered when there is no screenout but a significant amount of gravel is reversed after the treatment.

  • Other remedial measures includes pulling the sand control completion assembly 46 out of hole or other remedial treatments.
  • One or more sensors on the sand control completion system 10 may be used, in general, to observe at the Earth surface whether the gravel packing operation has proceeded as planned. Traditionally, a successful gravel packing operation may not be confirmed until the service tool is pulled out of hole and data from any memory gauges of the tool are downloaded and analyzed. However, because the sand control completion system 10 allows data to be monitored at the Earth surface in real time or near real time, the operator has the peace of mind knowing that everything is going well throughout the treatment. Moreover, the next phase or operation for the well may be planned even before the service tool 20 has been retrieved from the well.

  • One or more sensors of the sand control completion system 10 may also be used to detect and free the work string 12 if the work string 12 becomes stuck when going to reverse out position. In this manner, without the use of the sensor(s), it may not be possible to determine precisely the location at which the work string 12 is stuck. In this manner, the work string 12 may be stuck at the wash pipe 22, at the service tool 20, etc. Therefore, it is unclear as to how much upward force may be exerted on the work string 12 without exceeding the stuck component's tensile rating. Therefore, traditionally, it is assumed that the component of the work string 12, which has the minimum tensile rating is stuck; and the work string 12 is worked within those limits. If the work string 12 is not freed, then the exerted force is increased to the next lowest minimum tensile rating, etc.
  • Torque and drag modeling traditionally has been used to calculate the downhole force from the surface-applied force. However, this modeling may not be accurate or verifiable. Therefore, by using one or more sensors disposed on sand control completion system 10, several determinations may be made in real time or near real time: first, the component that is stuck may be identified by, for example, pulling upwardly on the work string 12 and then measuring the force at various points downhole to see where it is being transmitted; and secondly, the work string 12 may then be worked within the limits of the stuck component's maximum tensile rating by adjusting the surface force to get the required force downhole, as measured directly downhole and provided to the surface operator.
  • One or more sensors of the sand control completion system 10 may further be used to monitor and regulate the removal of the filter cake and/or an acid treatment. In this manner, although fluid may be communicated downhole through the end of the wash pipe 22 for the removal of filter cake, the filter cake and gravel pack fluid may not be effectively cleaned up, which results in reduced retained permeability and increased skin, which have negative effects on subsequent production.
