Introduction to Cementing | Drilling Course

Dec 17, 2015 The cement is used as a sealing material while drilling an oil and gas well. Pumping cement behind the casing provides a barrier to the fluids flow from or into the formation, and bonds the casing to the formation. This is called a primary cement job. Cement is also pumped for other reasons like sealing off perforated casing or plugging zones
