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
