Oil Well Cement - IS 8229
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 portland or pozzolanic cement with special organic retarders to prevent the cement from setting too quickly. Oil-well cements are used for oil-well grouting, sometimes called oil-well cementing. They consist of either portland or blended cements, plus additives. Oil-well cement must be slow-setting and able to withstand the high temperatures and pressures of these deep wells.
