Abstract

Methods and systems for hybrid frac completion include installing a hybrid completion system in a well and, in each zone of a first plurality of zones for plug & perf completion: activating an outer shroud of expanding shape memory polymer (SMP) around a liner, and perforating, using a perforation gun, a borehole wall. The methods further include, in each zone of the second plurality of zones for sliding sleeve completion: activating an SMP packer, and activating a sliding sleeve to expose the borehole wall. The methods further include fracturing the borehole wall by pressurizing the well; sealing, between each zone in the first and second plurality of zones, by actuating a plurality of isolation valves disposed in each zone of the first plurality of zones and each zone of the second plurality of zones; and removing the plurality of isolation valves to produce the well.

Claims (36)

1 . A method, comprising:

installing a hybrid completion system in a well, wherein the hybrid completion system is divided into a first plurality of zones for plug & perf completion and a second plurality of zones for sliding sleeve completion;

in each zone of the first plurality of zones for plug & perf completion:

activating an outer shroud of expanding shape memory polymer (SMP) around a liner, and

perforating, using a perforation gun, a borehole wall;

in each zone of the second plurality of zones for sliding sleeve completion:

activating an SMP packer, and

activating a sliding sleeve to expose the borehole wall,

wherein a pipe section with the sliding sleeve has SMP compartments;

fracturing, using a drilling system, the borehole wall by pressurizing the well;

sealing, between each zone in the first and second plurality of zones, by actuating a plurality of isolation valves disposed in each zone of the first plurality of zones and each zone of the second plurality of zones; and

removing the plurality of isolation valves to produce the well.

2 . The method of claim 1 , further comprising pumping a radio frequency identification (RFID) tag into the well.

3 . The method of claim 2 , wherein each of the plurality of isolation valves is activated by the RFID tag.

4 . The method of claim 2 , wherein the sliding sleeve is activated by the RFID tag.

5 . The method of claim 1 , wherein the plurality of isolation valves are removed by a drill bit.

6 . The method of claim 1 , wherein the SMP packer is activated by a solution.

7 . The method of claim 1 , wherein the outer shroud of the expanding SMP is activated by a solution.

8 . The method of claim 1 , wherein the SMP is an epoxy resin or an alkali metal.

9 . A system, comprising:

a hybrid completion system, configured to be installed in a well, wherein the hybrid completion system is divided into a first plurality of zones for plug & perf completion and a second plurality of zones for sliding sleeve completion;

an outer shroud of expanding shape memory polymer (SMP), configured to be activated around a liner in each zone in the first plurality of zones for plug & perf completion;

a perforation gun, configured to perforate a borehole wall;

an SMP packer, configured to seal a borehole;

a sliding sleeve, configured to expose the borehole wall,

wherein a pipe section with the sliding sleeve has SMP compartments;

a drilling system, configured to fracture the borehole wall by pressurizing the well;

a plurality of isolation valves, one in each zone of the first plurality of zones for plug & perf completion and the second plurality of zones for sliding sleeve completion, configured to seal each zone; and

a drill bit, configured to remove the plurality of isolation valves and produce the well.

10 . The system of claim 9 , further comprising a radio frequency identification (RFID) tag configured to be pumped into the well.

11 . The system of claim 10 , wherein each of the plurality of isolation valves is activated by the RFID tag.

12 . The system of claim 10 , wherein the sliding sleeve is activated by the RFID tag.

13 . The system of claim 9 , wherein the plurality of isolation valves are removed by the drill bit.

14 . The system of claim 9 , wherein the SMP packer is activated by a solution.

15 . The system of claim 9 , wherein the outer shroud of expanding SMP is activated by a solution.

16 . The system of claim 9 , wherein the SMP is an epoxy resin or an alkali metal.
