LWD in-situ sidewall rotary coring and analysis tool

摘要

An apparatus for estimating a property of an earth formation includes a carrier configured to be conveyed through a borehole penetrating the formation and a single probe configured to be extended from the carrier and to seal with a wall of the borehole. The apparatus further includes a fluid analysis sensor disposed at the carrier and configured to sense a property of a formation fluid sample extracted from the formation by the probe. A coring device is disposed at the carrier and configured to extend into the probe, to drill into the wall of the borehole, and to extract a core sample. A core sample analysis sensor is disposed at the carrier and configured to sense a property of the core sample. A processor is configured to receive data from the fluid analysis sensor and the core sample analysis sensor and to estimate the property using the data.
