FLUID CLEANING - TEST METHODOLOGY

All tests were run at ambient temperature and atmospheric pressure

1. Typical oil-based and synthetic based fl uids were formulated.

For challenging conditions, pure crude oil was used.

2. The FANN viscometer rotor was dipped into the drilling

fluid and then removed, leaving a deposit of drilling

fl uid on it.

Dosages of ULTROIL® WM 1001 diluted on NaCl saturated brine

3. The rotor was immersed into the fl ush solution of study, left

with agitation at 300RPM for 2 minutes and then removed.

4. The masses were assessed at each step so that the percentage

of fl uid removed from the rotor by the fl ush could be

evaluated.

5. Rotor’s overall appearance was also assessed through visual

inspection.
