The ShearMaster™

FLOATING DOWNHOLE STOP AND “SCALE BUSTER”

• Designed for wells producing sufficient fluid to cushion plunger fall without needing a bottom hole spring
• Set by simply dropping from surface – square bottom acts as a no-go
• Easily retrieved with a fishing plunger
• Static mixing chamber shears paraffin to reduce buildup in tubing
• Cleaning action works as the tool cycles in lower tubing
• Effective against paraffin and scale
• Commonly used in combination with a Viper Plunger as a “scale buster” to remove scale above the downhole spring – ELIMINATES ACID JOBS

• Hardened/plated tool steel for long life
• Unique design
• Hardened solid downhole with hollow core
• Reverse flutes eliminate spin while providing an effective shear
  mixing chamber
• Large open area of flutes and hollow core minimize travel during
  flow cycle”
