... to characterize the hydration of Portland cement in CO 2 injection wells. Properties of the Minnelusa formation in the Powder River Basin serve as a base case scenario. From this, we will run a sensitivity analysis to determine the influence of various parameters on cement hydration. These parameters consist...

... ABSTRACT: Casing force and deformation during MPC (managed pressure cementing) waiting setting stage in deep and ultra-deep wells significantly impacts wellbore integrity. To accurately analyze casing force, the cement hydration and heat release process during waiting setting of cement...

... ABSTRACT: This paper presents the results of numerical studies aiming to assess the effects of cement hydration on the casing integrity in superhot well conditions. Casing integrity challenges for high and super-high temperature geothermal wells were first discussed. A simplified well cement...

... kinetics law. However, the apparent activation energy that describes the temperature effect on cement hydration rate decreases significantly with the increase of temperature, suggesting much reduced effects in the high temperature range. Similar phenomena were observed for both curing temperature...

... the impact of cement hydration on stiffness development. An insight is presented on the development of shear wave velocity (Vs) with the ongoing hydration process during the first week after mixing. Developing self-desiccation suction in sealed samples was measured. The lack of significant early restraint...

... in-situ pressures at containment barricades. At the Cayeli mine, complex ore geology translates into variations in tailings chemistry and so appears to significantly affect the rate of cement hydration. This paper demonstrates how instrumentation can be deployed, and can be used to intelligently manage...
