This is the first report that presents literature review, experimental work and recent developments in this project. The experimental work consists of static tests and preliminary “Enhanced Sweeps”. This report includes the first batch of experimental results obtained from the tests conducted on the SSL (Small Sweep Loop) flow loop as well as preliminary successful static test results for oil droplet attachments. Based on results from preliminary flow loop tests, subsequent “Enhanced sweep” tests were conducted according to a modified Test Matrix. A preliminary analysis of the experimental data obtained is presented. The effects of parameters such as rheology, flow rate, bed heights and pressure drop are presented. The focus of this report will be the results from the “Enhanced Sweep” tests. The research also shows some interesting behavior of oil droplets attaching to cuttings. Because of the buoyant ability of the oil, it tends to lift the particle in the drilling fluid.
