Improved formation evaluation capability from near-wellbore logging using relative permeability modifers |
摘要 |
Nano-particles that possess either selective fluid phase blocks or modify the relative permeability of an earth formation to different fluids are used to inhibit the invasion of borehole mud into the formation. This makes it possible to make formation evaluation measurements using sensors with a shallow depth of investigation.
