WATER AS YOUR DRILLING FLUID?

Water by itself does NOT perform any of the drilling fluid functions well

Water may cause drilling problems

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”
