Downhole tool with one-piece slip

A downhole tool comprising:

• a mandrel made of composite material;
• a first slip disposed around the mandrel;
• a first cone disposed around the mandrel, and proximate to the first slip;
• a second slip disposed around the mandrel;
• a second cone disposed around the mandrel, and proximate to a first side of the second slip;
• a sealing element disposed around the mandrel, and between the first cone and the second cone;
• and
• a lower sleeve disposed around the mandrel, and proximate to a second side of the second slip,
• wherein the first slip comprises a circular slip body having one-piece configuration with at least partial connectivity around the entire circular slip body;
• and at least two grooves disposed therein, wherein the circular slip body is made from filament wound material,
• wherein the circular slip body comprises a plurality of inserts disposed therein, and
• wherein at least one of the plurality of inserts comprises a flat surface.

A downhole tool useable for isolating sections of a wellbore, the downhole tool comprising:

• a mandrel made of filament wound material;
• and
• a composite slip disposed on the mandrel, the composite slip further comprising a slip body having a one-piece configuration, and at least three slip grooves,
• wherein the at least three slip grooves are substantially equidistantly spaced from each other.

A downhole tool comprising:

• a mandrel made of a composite material;
• a composite slip disposed on the mandrel, the composite slip further comprising a one-piece configuration;
• a first cone disposed on the mandrel, and proximate to the composite slip;
• a metal slip disposed on the mandrel, the metal slip further comprising serrated teeth;
• a second cone disposed on the mandrel, and proximate to a first side of the metal slip;
• a sealing element disposed on the mandrel, and between the first cone and the second cone;
• and
• a lower sleeve disposed around the mandrel, and proximate to a second side of the metal slip,
• wherein the composite slip comprises a plurality of grooves in the range of between about 4 to 8 grooves.
