FORMATION EVALUATION SYSTEM AND METHOD
First Claim
1. An apparatus, comprising:
- a downhole tool configured for conveyance within a wellbore extending into a subterranean formation, the downhole tool comprising;
a fluid sampling system configured to draw fluid from the formation into the downhole tool;
a fluid monitoring device in communication with at least a portion of the fluid drawn into the downhole tool through the fluid sampling system, wherein the fluid monitoring device is configured to generate a signal indicative of a characteristic of the fluid; and
a controller configured to process the signal to estimate a level of contamination in the fluid and automatically generate a control signal when the estimated level of contamination meets a predetermined value.

Abstract
Methods and apparatuses for evaluating a fluid from a subterranean formation of a wellsite via a downhole tool positionable in a wellbore penetrating a subterranean formation are provided. The apparatus relates to a downhole tool having a probe with at least two intakes for receiving fluid from the subterranean formation. The downhole tool is configured according to a wellsite set up. The method involves positioning the downhole tool in the wellbore of the wellsite, drawing fluid into the downhole tool via the at least two intakes, monitoring at least one wellsite parameter via at least one sensor of the wellsite and automatically adjusting the wellsite setup based on the wellsite parameters.

15. A method, comprising:
-
conveying a downhole tool within a wellbore extending into a subterranean formation; operating a fluid sampling system of the downhole tool to draw fluid from the formation into the downhole tool; generating a signal indicative of a fluid characteristic of the fluid drawn into the downhole tool through the fluid sampling system, wherein generating the signal uses a fluid monitoring device in communication with at least a portion of the fluid drawn into the downhole tool; processing the signal using a controller to estimate a level of contamination in the fluid; and generating a control signal automatically when the estimated level of contamination meets a predetermined value. - View Dependent Claims (16, 17, 18, 19, 20)
