Title
(EN) DOWNHOLE SAMPLE EXTRACTORS AND DOWNHOLE SAMPLE EXTRACTION SYSTEMS
(FR) EXTRACTEURS D'ÉCHANTILLONS DE FOND DE TROU ET SYSTÈMES D'EXTRACTION D'ÉCHANTILLONS DE FOND DE TROU
Abstract
(EN)
The disclosed embodiments include downhole sample extractors and downhole sample extraction systems. In some embodiments, the downhole sample extractor includes a sample container chamber that holds a sample container containing a downhole sample. The downhole sample extractor also includes a sample extraction chamber having an internal chamber that is partially filled with a carrier solution, wherein the downhole sample is mixed with the carrier solution in the internal chamber of the extraction container. The downhole sample extractor further includes a first piston that, when actuated, inserts the sample container into the internal chamber of the sample extraction chamber.
