| Abstract | The cement sheath in thermal recovery oil wells is subjected to elevated temperatures up to about 320°C during the injection of steam to stimulate high viscosity crude oil production. Initially the cement sheath in these wells is pre-cured at formation temperature (=40°C) prior to being exposed to steam treatment. Steam treatment can be performed anytime from immediately after the cement has set to years later. It is generally assumed that the cement chemistry and microstructure resulting on steam injection is similar to that obtained for geothermal cements where the cement sheath is heated directly to elevated temperatures as it is pumped downhole and cured at those temperatures. The objective of this study was to determine the impact of steam treatment on the microstructure and chemistry of pre-cured cement pastes. |
