Patent number: 7603897Abstract: A downhole, extendable apparatus and methods of use are described and claimed herein. In one embodiment, the extendable apparatus includes a piston that extends toward a borehole wall, the piston having an inner sampling member that is also extendable. The sampling member may be further extended to engage the borehole wall and penetrate the formation. The sampling member may also include a screen and an inner scraper or wiper that frictionally engages the screen and reciprocates to remove debris from the screen. The piston may comprise a seal pad having an internal cavity for receiving a volume of fluid. In another embodiment, the extendable apparatus comprises multiple, concentric pistons for extending the sampling member further toward the borehole wall than is possible with a single piston. The extendable apparatus may also include a retraction contact switch and position indicator.Type: GrantFiled: May 20, 2005Date of Patent: October 20, 2009Assignee: Halliburton Energy Services, Inc.Inventors: Gregory N.

Patent number: 7216533Abstract: A method of testing a downhole formation using a formation tester on a drill string. The formation tester is disposed downhole on a drill string and a formation test is performed by forming a seal between a formation probe assembly and the formation. A drawdown piston then creates a volume within a cylinder to draw formation fluid into the volume through the probe assembly. The pressure of the fluid within the cylinder is monitored. The formation test procedure may then be adjusted. The test procedure may be adjusted to account for the bubble point pressure of the fluid being monitored. The pressure may monitored to verify a proper seal is formed or is being maintained. The test procedure may also be performed by maintaining a substantially constant drawdown rate using a hydraulic threshold or a variable restrictor.Type: GrantFiled: May 19, 2005Date of Patent: May 15, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Malcolm D. McGregor, Gregory N. Gilbert, Mark A. Proett, James M. Fogal, David Welshans, Glenn C. Gray, Svetozar Simeonov, Laban M. Marsh, Jean Michel Beique, James E. Stone
