A proprietary cementing-job simulation software has been upgraded with a losses model. Using the losses model will enable the design engineer to define loss zones in the wellbore. For each identified loss zone, a percentage of losses can be provided. Loss-input and other well and fluid data allow a detailed dynamic simulation.
