Comparison of Elastic Modulus between Class G Cement and Geopolymer Cement under HPHT Condition

Well cementing is one of the important systems in oil and gas drilling. It provides support and protection to the casing, prevent the movement of fluid through the annular space outside the casing; stop the movement of fluid into vugular or fractured formations and it also use to close an abandoned...
