Well Casing is the tube-shaped structure placed in the well to maintain the well opening from the target ground water to the surface. Along with grout, the casing keeps dirt and excess water out of the well. This helps prevent contaminants from less desirable groundwater from entering the well and mixing with the drinking water.

The best time to protect concrete is when it is new, before harsh chemicals like acids, salts and sulfates have had a chance to get inside the concrete and cause damage. Unfortunately, there are thousands of concrete tanks that were built in the '70s and '80s that were not adequately protected.
For safe pumping out of extracted oil steel casing is inserted. It is likely that if oil is struck, oil or gas may escape through the space between the rock formation and steel casing. To fill this space Oil well cement is used. Oil well cement is manufactured by adding retarders (Starches or cellular products) to Ordinary Portland cement.
