Sampling Tool With Dual Flowline Architecture

A method of analyzing a geotechnical formation, comprising:

• withdrawing a fluid from the geotechnical formation through an evaluation flowline and a cleanup flowline;
• routing the fluid through a flowline analysis module;
• and
• calibrating the fluid analysis module based on at least one measurement obtained by a single spectrometer in the fluid analysis module.

A method of analyzing a geotechnical formation, comprising:

• withdrawing a fluid from the geotechnical formation through an evaluation flowline and a cleanup flowline;
• configuring a fluid routing module to perform at least one of directing fluid from the evaluation flowline into the cleanup flowline, directing fluid from the cleanup flowline to the evaluation flowline, directing fluid from the evaluation flowline into a subsequent section of the evaluation flowline, and directing fluid from the cleanup flowline into a subsequent section of the cleanup flowline;
• and
• calibrating a fluid analysis module positioned downstream from the subsequent section of the cleanup flowline and the subsequent section of the evaluation flowline based on at least one measurement obtained by the fluid analysis module.
