Hybrid-Tieback Seal Assembly Using Method and System for Interventionless Hydraulic Setting of Equipment when Performing Subterranean Operations

A hybrid-tieback seal assembly comprising:

• one or more anchoring bodies;
• one or more packer seal assemblies;
• one or more interventionless hydraulic setting systems coupled to one or more of the anchoring bodies and packer seal assemblies, the one or more interventionless hydraulic setting systems comprising:
• a first compensating volume positioned in an annular space between a hydraulic tubing and a communication port housing;
• a first working volume positioned in the annular space between the hydraulic tubing and the communication port,
• wherein the first working volume is located adjacent the first compensating volume and separated from the first compensating volume by one or more hydraulic control devices, and
• wherein a change in pressure of the first compensating volume changes pressure of the first working volume;
• a second working volume positioned in the annular space between the hydraulic tubing and the communication port,
• wherein the second working volume is located between the first working volume and a second compensating volume in an annular space between the hydraulic tubing and the communication port housing,
• wherein the second working volume is separated from the second compensating volume by one or more hydraulic control devices, and
• wherein a change in pressure of the second compensating volume changes pressure of the second working volume;
• a pressure delivery port,
• wherein a shifting sleeve is operable to open and close the pressure delivery port in response to a pressure differential between the first working volume and the second working volume, and
• wherein the pressure delivery port delivers pressure to one or more of the anchoring bodies and packer seal assemblies.

A method to tie a well back to the surface comprising:

• running a hybrid-tieback seal assembly into a wellbore, the hybrid-tieback seal assembly comprising one or more anchoring bodies and one or more packer seal assemblies;
• landing a wellhead hanger in a wellhead;
• setting the anchoring bodies within a host casing;
• and
• setting the one or more packer seal assemblies within at least one of a receptacle of a previously installed liner hanger system and a host casing above a previously installed hanger system.
