Erle P. Halliburton received a 1921 patent for an improved method for cementing oil wells. It brought greater petroleum production and environmental safety.

Oil-well cements are used for cementing work in the drilling of oil wells where they are subject to high temperatures and pressures. They usually consist of 

27 Feb 2018 Petroleum cement is a special cement used for the cementing of oil and gas wells . Its main objective is to separate the various production zones. could be used as an option in the cementing of oil wells. To enable this study a linear programming method was used for the composition of the new cement,  Oil Well Cement W-60, Gypsum products for expansion and set control of Portland cement in oil well applications. The report substantiates the expediency of employment of expanding oil well Cements with oxide expansion are developed that are used for well cementing. 16 Nov 2017 During that period, a need arose for standardization of cement testing. The API Committee on Oil-Well Cements issued in 1948 the first edition of  Compressive Strength testers are used to determine the compressive strength development, gel strength development and elastic moduli of oil well cement  For Portland cement to qualify as oil well cement, the chemical and physical properties must meet the required standards of the American Petroleum Institute ( API).

Since this research is focusing on oil well cement, we will not discuss the ASTM standards for Portland cement in details. 2.2.2. The American Petroleum Institute  

The cement slurry is placed between the casing and the drilled formation for adequate zonal isolation for the lifetime of the well [1]. Cementing operation is  1 May 1987 One of the principal difficulties encountered in dealing with cement of additive used, the rate of heat flux into the slurry as well as the final  Oil Well Cement Testing. Cement is used to hold casing in place and to prevent fluid migration between subsurface formations. The use of API testing

Part of the process of preparing a well for further drilling, production or abandonment, cementing a well is the procedure of developing and pumping cement into place in a wellbore. Used for a Oil Well Cement Testing Cement is used to hold casing in place and to prevent fluid migration between subsurface formations. The use of API testing procedures over the years has created a large body of experience-based knowledge about slurry performance in specific geological formations in the wellbore. Oil well cement finds a wide application in the exploration for and the production of oil and gas. For securing the metal casing and liners, out of which the oil and gas eventually flow. Oil well cement can also be used for sealing water wells, waste disposal wells, and geothermal wells. they fulfill the requirements for materials forming low-viscosity slurries, which remain pump able to 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. Oil Well Cementing Additives.
