Abstract
Official abstract text for this publication.
An apparatus comprising a downhole tool configured for conveyance within a borehole penetrating a subterranean formation, wherein the downhole tool comprises: a probe assembly configured to seal a region of a wall of the borehole; a perforator configured to penetrate a portion of the sealed region of the borehole wall by projecting through the probe assembly; a fluid chamber comprising a fluid; and a pump configured to inject the fluid from the fluid chamber into the formation through the perforator.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for conveyance within a borehole extending into a subsurface formation, the apparatus comprising: a probe assembly disposed in a first portion of a tool body; an actuator configured to move the probe assembly between a retracted position and a deployed position, wherein the probe assembly is configured to seal a region of the borehole wall when in the deployed position; a perforator configured to penetrate the borehole wall at a plurality of…
