Patent ID: 8132621

Claim:
A method of evaluating multiple subterranean zones during a single trip into a wellbore, the method comprising the steps of: interconnecting a formation evaluation assembly in a coiled tubing string; for each of the multiple zones, displacing the coiled tubing string including the formation evaluation assembly to a position proximate the respective zone, receiving formation fluid from the respective zone into the formation evaluation assembly by using a downhole pump to draw the formation fluid into the formation evaluation assembly, determining at least one characteristic of the formation fluid, and pumping a sample of the formation fluid to a surface location using the downhole pump; performing the multiple displacing, receiving, determining and pumping steps during the single trip of the coiled tubing string into the wellbore; providing the coiled tubing string with adjacent passages in fluid communication with each other at opposite ends of the passages; interconnecting the pump in a first one of the passages; and displacing a formation evaluation instrument through a second one of the passages.
