SMOOTH DRAW-DOWN FOR FORMATION PRESSURE TESTING |
摘要 |
A method and apparatus for of determining a formation parameter of interest. The method includes placing a tool into communication with the formation to test the formation and drawing down a test volume at an increasing draw rate during a first draw period and decreasing the draw rate during a second draw period to create a smooth draw down cycle. The draw down can be step-wise or continuous. The formation parameter is determined using formation rate analy is and characteristics determined during the draw down cycle.
