A successful wellbore cleanup is one of the most critical steps to ensure a trouble-free completion. Cleanup operations reduce the risk of formation damage and enhance well productivity by efficiently and meticulously planning out the removal of leftover drilling fluid residue and casing debris. In addition to spacer chemistry and cleanup tools, advanced displacement software has contributed to creating a more competent displacement process leading to lower operation costs and increased production.

PVI’s CleanMax+, the advanced version of CleanMax, is designed for deepwater operations involving displacements using the choke, kill, and boost lines.. CleanMax+ predicts the temperature distributions in the wellbore by calculating the transient heat transfer between wellbore and sea water/rock formation.
