  2. Problem • Used drilling mud may contain hazardous and foreign substances leading to: • Complex and costly disposal methods • Potential long term environmental liabilities for producers • High costs for remediation • Increasingly stringent regulatory environment(s) • Negative public perception (land contamination / water use)

  3. HDD - Problem Vac truck hauling to landfillhigh tipping feeslong term environmental liability sludge pit

  4. PitDryTM Solution • One Step Process • PitDry™ Mixer used in combination with dry reagents • Results in solidification of solid/liquid mud/waste

  5. Vac truck hauling to landfillhigh tipping feeslong term environmental liability HDD – PitDry™ Solution PitDry™ No tipping fees – landfill cover or on-site spread sludge pit

  6. HDD PIT DRY Test Sept 28/05 The following pictures show the progress of the test conducted September 28, 2005. The test was to see the effects of pumping directly on to a flat surface (on-site spread) and if the resulting effluent setup the same as it does in a dump truck box (hauling for landfill cover). The approx. total amount of the fluid was 4500 us gal Aprox. run time 57 min. (start time 11:06 end time 11:59) Average flow 79 gpm. Test was successful!

  24. Summary • In approximately one hour, approximately 4,500 gal (US) (17 cubic meters, or 22 cubic yards) were processed and mixed with reagents which resulted in stackable solids which could be site spread or hauled away to a landfill in a dump truck. • The reagents combine with the water and spent mud to trap and bind contaminating constituents thus making them non-hazardous. • Output solid met all Ontario disposal requirements – considered dirt – spreadable/disposable anywhere

  25. Conclusion This test has shown that we can turn waste drilling fluids and residue to environmentally compliant transportable/land disposable solids, using a simple robust method (equipment, reagents, and process) thereby eliminating problems/costs with current waste fluid disposal methods.
