Apparatus and methods for sampling and testing a formation fluid |
摘要 |
A formation test tool and methods are described that enable sampling and measurements of parameters of fluids contained in a borehole while reducing the time required for taking such samples and measurements and reducing the risk of formation damage due to sampling induced pressure spikes. The tool has a quick response control system for controlling a fluid transfer device in response to fluid pressure near a sampling port.
