15. January 2011 “For External Distribution.© 2011 Halliburton. All Rights Reserved.” This Week  This drilling fluids workshop is all about the practical application of drilling fluids science  Everything we talk about addresses the functions of drilling fluids and how these effect you  Properties & Testing  Mixing  Bentonite and Polymers  Products  Applications to field conditions

16. January 2011 “For External Distribution.© 2011 Halliburton. All Rights Reserved.” WATER AS YOUR DRILLING FLUID?  Water by itself does NOT perform any of the drilling fluid functions well  Water may cause drilling problems

17. January 2011 “For External Distribution.© 2011 Halliburton. All Rights Reserved.” ARE YOU EXPECTING THIS?

18. January 2011 “For External Distribution.© 2011 Halliburton. All Rights Reserved.” Drilling Fluids  Magic doesn’t exist  Therefore we must pay attention to each and every part of the drilling program, and this week, drilling fluids in particular  One size does not fit all  “Engineered fluid solutions to maximize wellbore value”
