Internal slip including one or more symmetrical teeth

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;
• 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;
• an internal slip disposed radially between the stroke sleeve and the base, the internal slip including:
• a tubular, the tubular having a tubular inner diameter (IDt), a tubular outer diameter (ODt), a first end and a second end, wherein the tubular is circumferentially continuous proximate the first end and circumferentially discontinuous proximate the second end, the circumferentially discontinuous second end configured to reduce a radial stiffness of the tubular;
• a first set of teeth disposed along the tubular inner diameter (IDt), the first set of teeth configured to engage with the base teeth;
• and
• a second set of teeth disposed along the tubular outer diameter (ODt), the second set of teeth configured to engage with the stroke sleeve teeth, wherein the stroke sleeve teeth, the second set of teeth, the first set of teeth, and the base teeth are configured to 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;
• 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;
• an internal slip disposed radially between the stroke sleeve and the base, the internal slip including:
• a tubular, the tubular having a tubular inner diameter (IDt), a tubular outer diameter (ODt), a first end and a second end, wherein the tubular is circumferentially continuous proximate the first end and circumferentially discontinuous proximate the second end, the circumferentially discontinuous second end configured to reduce a radial stiffness of the tubular;
• a first set of teeth disposed along the tubular inner diameter (IDt), the first set of teeth configured to engage with the base teeth;
• and
• a second set of teeth disposed along the tubular outer diameter (ODt), the second set of teeth configured to engage with the stroke sleeve teeth, wherein the stroke sleeve teeth, the second set of teeth, the first set of teeth, and the base teeth are configured to 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.
