Non-metallic slip assembly and related methods

A downhole tool for isolating a wellbore, the downhole tool comprising:

• a mandrel made of non-metallic material, the mandrel having a first outer diameter at a first end thereof and a second outer diameter at a second end thereof, the first outer diameter being greater than the second outer diameter and comprising an isolation region;
• a slip assembly coupled to the mandrel around the second outer diameter;
• a packing element coupled to the mandrel around the second outer diameter;
• and
• a shoe coupled to a second end of the mandrel along the second outer diameter.

A downhole tool for isolating a wellbore, the downhole tool comprising:

• a mandrel made of non-metallic material, the mandrel comprising an isolation region at a first end of the mandrel;
• a shear sleeve adapter disposable on an outer surface of the isolation region, the shear sleeve adapter having holes aligned with holes in the outer surface of the isolation region;
• a shoe positioned around the outer surface of the mandrel at a second end of the mandrel;
• a packing element positioned around the outer surface of the mandrel;
• and
• a slip assembly positioned around the outer surface of the mandrel, wherein the slip assembly comprises:
• a first slip carrier made of non-metallic material coupled to the mandrel adjacent to the isolation region;
• a plurality of first slip inserts coupled to the first slip carrier, the first slip carrier and plurality of first slip inserts forming a first assembly;
• and
• a second slip carrier made of non-metallic material coupled to the mandrel adjacent to the shoe;
• and
• a plurality of second slip inserts coupled to the second slip carrier, the second slip carrier and the plurality of second slip inserts forming a second slip assembly.
