Abstract
System and methods for cleaning debris or particulates from a wellbore using foam is provided, including predicting if a foam cleanout of a well is feasible by calculating foam properties at each of a number of segments in a well during a foam cleanout, comparing the foam properties to screening limits, providing an output to indicate if a foam cleanout is feasible. If feasible, the foam cleanout is performed.
