Advantages

• Not adversely affected by pressure, temperature, or mud chemistry.
• Can be used in any type of system.
• Superior strength and 75% roundness.
• Contains no free silica.

Application

• Horizontal Drilling—Improved sliding ability, extended lateral drilling capability.
• Deviated, crooked holes—Reduced torque and drag.
• Running casing, liner—Reduced drag created by closer tolerances and stiffer hook up.
