Abstract
Official abstract text for this publication.
A downhole formation fluid pumping and a sampling apparatus are disclosed that may form part of a formation evaluation while drilling tool or part of a tool pipe string. The operation of the pump is optimized based upon parameters generated from formation pressure test data as well as tool system data thereby ensuring optimum performance of the pump at higher speeds and with greater dependability. New pump designs for fluid sampling apparatuses for use in MWD systems are also disclosed.
First claim
Opening claim text (preview).
What is claimed: 1. A method for controlling a pumping system of a formation fluid sampling tool during formation fluid sampling, comprising: collecting in situ measurements from at least one sensor in the tool; and using the measurements in adaptive feedback loops to control performance of the pumping system. 2. The method of claim 1 wherein the method is capable of operating the pumping system of the tool with no operator interference.…
