... no losses during pumping and displacement of cement. Any downhole losses induced would results in insufficient barrier and compromise long-term well integrity. As the target reservoir was classed as oil & gas bearing, this could further lead to gas flow from the surrounding formation to flow to surface...

... of a wellbore with excessive washouts, which prevents drilling mud displacement and good casing centralization, therefore increasing the probability of drilling mud channels in the annular cement column. Conversely, the drilling mud density should not be greater than the formation's fracturing pressure...
