This is the third report being presented for this project. This report presents experimental results obtained from the tests conducted on the Low Pressure Ambient Temperature flow loop as well as results from the preliminary tests conducted on the Elevated Pressure Elevated Temperature flow loop. Based on results from previous “sweep” tests conducted, subsequent “sweep” tests were conducted according to a modified Test Matrix. A detailed analysis of the experimental data obtained is presented. The effect of parameters such as, rheology, flow rate & drill pipe rotation on volumetric cutting concentration removed, bed heights and pressure drop are presented. The modified mechanistic model for the critical re-suspension velocity for cutting in yield power law fluid is presented. The focus of this report will be on the results obtained from the “sweep” tests.
