So the problem first becomes WHAT DENSITY FLUID DO I USE? This slide will lead into the discussion and visual demonstrations… AVI’s provided by HEI. Here we’re going to talk about Boycott, Roping, Slump, etc. In most cases better displacement is achieved when the displacing fluid is heavier than the displaced fluid. However, this does not mean that you should use a 17.0 ppg cement slurry to displace a 10.0 ppg mud…in fact…..when density differentials exceed 2 ppg between adjacent fluids flip-flopping or gravitational exchange can occur

A phenomenon known as "roping" has been suspected as the cause of inefficient displacement of mud with the cement. One suspected cause is the necessity of pumping the cement through the float shoe and float collar which have fairly small bores. The flow pattern of the cement emerging from the float shoe and float collar is such that it leaves pockets of mud trapped which are not displaced by the cement. These pockets of mud then can become the source of future leakage problems through the cement job through the shoe track.
