Anti-preset for packers

A well system, the well system comprising:

• a wellbore penetrating a subterranean formation;
• and
• a packer assembly, the packer assembly including:
• an inner mandrel;
• a packing element at least partially surrounding the inner mandrel;
• a packing element activation sleeve coupled to the packing element;
• a hydrostatic setting assembly engageable with the packing element activation sleeve, the hydrostatic setting assembly including:
• a hydrostatic piston;
• a hydrostatic prop piston engageable with the hydrostatic piston to push the hydrostatic piston to engage the packing element activation sleeve;
• and
• a hydrostatic locking mechanism, the hydrostatic locking mechanism engageable with the hydrostatic prop piston to maintain the hydrostatic piston in a hydrostatic locked position;
• and
• a hydraulic setting assembly positioned between the packing element and the hydrostatic setting assembly, the hydraulic setting assembly including:
• a hydraulic piston;
• a hydraulic locking mechanism coupled to the hydraulic piston;
• a hydraulic prop piston engageable with the hydraulic locking mechanism, the hydraulic prop piston operable to allow the hydraulic locking mechanism to move from a hydraulic locked position to a hydraulic unlocked position.

A method for setting a packing element into a wellbore, the method comprising:

• running a packer assembly into a wellbore, the packer assembly including:
• an inner mandrel;
• a packing element at least partially surrounding the inner mandrel;
• a packing element activation sleeve coupled to the packing element;
• a hydrostatic setting assembly engageable with the packing element activation sleeve, the hydrostatic setting assembly including:
• a hydrostatic piston;
• a hydrostatic prop piston engageable with the hydrostatic piston to push the hydrostatic piston to engage the packing element activation sleeve;
• and
• a hydrostatic locking mechanism, the hydrostatic locking mechanism engageable with the hydrostatic prop piston to maintain the hydrostatic piston in a hydrostatic locked position;
• and
• a hydraulic setting assembly positioned between the packing element and the hydrostatic setting assembly, the hydraulic setting assembly including:
• a hydraulic piston;
• a hydraulic locking mechanism coupled to the hydraulic piston;
• a hydraulic prop piston engageable with the hydraulic locking mechanism, the hydraulic prop piston operable to allow the hydraulic locking mechanism to move from a hydraulic locked position to a hydraulic unlocked position;
• determining that the hydrostatic setting assembly failed to engage the packing element activation sleeve;
• running a plug downhole into the packer assembly;
• and
• applying differential pressure from uphole to release the hydraulic locking mechanism and allow pressure to move the packing element activation sleeve uphole to engage the packing element.
