Abstract
Official abstract text for this publication.
A formation tester tool can include a longitudinal probe drill collar having a surface, a formation probe assembly located within the probe drill collar, the formation probe assembly including a piston reciprocal between a retracted position and an extended position beyond the probe drill collar surface, the piston being slidingly retained within a chamber, a seal pad located at an end of the piston, the seal pad including an outer surface defining a partial cylindrical surface. The piston includes an outer surface having non-circular cross-sectional shape and the chamber includes an inner surface having a non-circular shape similar to the shape of the piston outer surface. The formation tester tool can include interchangeable draw down assemblies and a flow bore having a curving path.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: using a formation tester tool having a formation probe assembly having a piston slidingly engaged within a chamber and extendable beyond an outer surface of the formation tester tool, the piston including a seal pad at an end of the piston, the seal pad including an outer surface having a partial cylindrical surface shaped to be substantially congruent with a wall surface of a borehole, and the seal pad having a substantially equal thick…
