The investigations conducted within the scope of this project are a consistent continuation of the work already performed at ITE, especially DGMK research projects 444-1 and 444-2. Essential parameters examined in the course of this project include the longterm stability behavior of CaO and MgO swelling cements under conditions similar to those prevailing in the borehole (storage medium, temperature, pressure), possibility of using more reactive magnesium oxides at static formation temperatures of 70 C to 120 C, and the expansion behavior of CaO swelling cements after being subjected to realistic shear, temperature, and compressive stress in a circulation system. For subjecting the cement slurry to realistic shear stress, a circulation syst...
