CemCADE cementing design and evaluation software Cementing in today’s challenging wells is a complex task. Wells may have depleted intervals, resulting in narrow windows between pore and fracturing pressures. Deviations can make casing standoff by centralizers hard to determine. Mud removal may be difficult as a result of the standoff and exotic drilling fluids. CemCADE software provides tools to assist the engineer in evaluating all the parameters and in designing cementing slurries and procedures to cement the well and achieve the required zonal isolation. The software is used for all types of wells and casings, from land to offshore in deepwater and from large-diameter conductor casing to the deepest production liner. Tools assist in calculation of centralizer placement, pump rates and spacer properties to achieve mud removal and cement placement; calculation of densities and pumping parameters help maintain well control. Additional tools evaluate the risk of gas migration and allow the engineer to select appropriate solutions to minimize this risk. A module assists engineers in designing plugs to minimize contamination during placement, resulting in much higher plug-setting success. A simulator aids in determining the temperatures to expect during cementing, providing better data for cement slurry design and better schedules for thickening-time tests and compressive-strength tests to determine optimum WOC.
