Abstract

An AICD ICD screen with a gravel pack bypass port and sliding sleeve This would enable gravel pack fluid to bypass the AICD ICD during gravel pack operations and allow for conventional packing with a full beta wave and a greater pack percentage When gravel packing AICD screens it is currently not possible to utilize differential washpipe valves This is due to the pressure drop through the AICDs having the potential to open the valve early This reduces the maximum completion length and also reduces the effectiveness of annular packers when gravel packing AICDs Differential washpipe valves are required to insure the packer is not covered with gravel during the beta wave making full zonal isolation impossible Use of this design would allow for the use of beta breaker valves and hence open hole annular packers for zonal isolation The idea is to design the AICD screen with a flow port that would allow flow to bypass the ICD and then be covered by a sliding sleeve after gravel packing This would then allow the well to be gravel packed as per a normal alpha beta pack before the sleeves were closed by a shifting tool when POOH after the pack is in place The benefits of this would be that it could allow conventional packing of an AICD with a very high resistance to water flow high FRR and it would also allow for the use of differential washpipe valves so that zonal isolation could be installed as per a normal compartmentalized gravel pack design

AICD Screen with Gravel Pack Port and Sliding Sleeve

An AICD/ICD screen with a gravel pack bypass port and sliding sleeve. This would enable gravel pack fluid to bypass the AICD/ICD during gravel pack operations and allow for conventional packing with a full beta wave and a greater pack percentage. When gravel packing AICD screens it is currently not possible to utilize differential washpipe valves. This is due to the pressure drop through the AICDs having the potential to open the valve early. This reduces the maximum completion length and also reduces the effectiveness of annular packers when gravel packing AICDs. Differential washpipe valves are required to insure the packer is not covered with gravel during the beta wave, making full zonal isolation impossible. Use of this design would allow for the use of beta breaker valves and hence open hole annular packers for zonal isolation.

The idea is to design the AICD screen with a flow port that would allow flow to bypass the ICD and then be covered by a sliding sleeve after gravel packing. This would then allow the well to be gravel packed as per a normal alpha beta pack before the sleeves were closed by a shifting tool when POOH after the pack is in place. The benefits of this would be that it could allow conventional packing of an AICD with a very high resistance to water flow (high FRR), and it would also allow for the use of differential washpipe valves so that zonal isolation could be installed as per a normal compartme...
