Internal slip design with minimum backlash for packers seal enhancement

A well system, comprising:

• a wellbore located in a subterranean formation;
• and
• a sealing/anchoring assembly positioned in the wellbore, the sealing/anchoring assembly including:
• a mandrel;
• a sealing/anchoring element positioned about the mandrel, the sealing/anchoring element configured to move between a radially retracted state and a radially expanded state;
• and
• a ratch latch body coupled to the sealing/anchoring element, the ratch latch body configured to hold the sealing/anchoring element in the radially expanded state, the ratch latch body including:
• a stroke sleeve having a stroke sleeve outer diameter (ODSS) and a stroke sleeve inner diameter (IDSS), the stroke sleeve inner diameter (IDSS) having a plurality of stroke sleeve teeth disposed thereon;
• and
• a base having a base outer diameter (ODB) and a base inner diameter (IDB), the base outer diameter (ODB) having a plurality of base teeth disposed thereon, the stroke sleeve teeth and the base teeth configured to directly ratchet along one another to hold the sealing/anchoring element in the radially expanded state.

A method, comprising:

• positioning a sealing/anchoring assembly within a wellbore located in a subterranean formation, the sealing/anchoring assembly including:
• a mandrel;
• a sealing/anchoring element positioned about the mandrel, the sealing/anchoring element configured to move between a radially retracted state and a radially expanded state;
• and
• a ratch latch body coupled to the sealing/anchoring element, the ratch latch body configured to hold the sealing/anchoring element in the radially expanded state, the ratch latch body including:
• a stroke sleeve having a stroke sleeve outer diameter (ODSS) and a stroke sleeve inner diameter (IDSS), the stroke sleeve inner diameter (IDSS) having a plurality of stroke sleeve teeth disposed thereon;
• and
• a base having a base outer diameter (ODB) and a base inner diameter (IDB), the base outer diameter (ODB) having a plurality of base teeth disposed thereon, the stroke sleeve teeth and the base teeth configured to directly ratchet along one another to hold the sealing/anchoring element in the radially expanded state;
• and
• actuating the stroke sleeve or base to move the sealing/anchoring element from the radially retracted state to the radially expanded state.
