The drill pipe foam wiper balls is designed to wipe drillpipe or tubing string clean of cement, fluids, or debris, and can be used to separate fluids.

These drill pipe foam wiper balls are made of natural rubber and can be used in a temperature range of 40°F (4°C) to 302°F (150°C). The ball has a parting stretch of 380 to 440%, which means it can pass through small restrictions without being damaged.

The wiper ball can be loaded into drill pipe or tubing connections.

It easily passes through internal upset restrictions such as mechanical setting tools, diverters, and liner running tools, and multiple balls can be pumped if necessary.

Foam wiper balls have been used with all types of drilling and displacement fluids.

A major factor in drill bit selection is the type of formation to be drilled. The effectiveness of a drill bit varies by formation type. There are three types of formations: soft, medium and hard. A soft formation includes unconsolidated sandsclays, soft limestones, red beds and shale. Medium formations include calcitesdolomites, limestones, and hard shale. Hard formations include hard shale, calcites, mudstones, cherty lime stones and hard and abrasive formations.
