Using Predictive Software to Minimize Risks of Lost Circulation, Multi-Stage and Liner Cementing Jobs


 Cementing hydraulic modeling software is a powerful tool used to evaluate the hydrostatic impact during cementing placement. The input of accurate data can simulate the Equivalent Circulating Density (ECD) impact of the cementing design in the wellbore. The same software can utilize Computational Fluid Dynamics (CFD) to create a 3D model simulating the effects of fluid intermixing and flow, plus the final position of total fluids to understand and minimize risks presented in multi-stage and liner cementing jobs. ECD is traditional primary area of focus measuring the impact of friction pressure from fluid flow and the total hydrostatic pressure from fluid density at a depth. The software shows downhole annular pressures and ECDs versus fluid volume pumped into the wellbore at multiple depths. The CFD modeling capability also empowers the user to understand the impact of intermixed fluids at their final depth of placement. The software user is better equipped to incorporate positive design changes to influence the outcome of the real time operation. Whether ECD management or displacement efficiency improvement, the user can make knowledgeable decisions based on iterative simulation cases by assessing and monitoring specific variables within the software.
