Cuttings

Contact

Drill cuttings represent one of the most economical ways to acquire samples from a wellbore.  Cuttings are a byproduct of drilling the well and are brought to the surface through the mud system for study or disposal.  Cuttings are used by the mudlogger at the wellsite to provide a quick lithology identification as the well is being drilled.  These samples are regularly collected and stored for potential future analysis.

These samples can be evaluated in the lab at relatively low cost.  Most cuttings samples are suitable for a wide variety of lab analyses that provide valuable insight into the lithologic, mineralogic, biostratagraphic, and geochemical make-up of the strata present in the borehole.  


Drill Cuttings

Careful attention is paid to the handling of cuttings in the lab.  Each sample is carefully assessed to determine the quality of the cuttings and their suitability for various analyses.  Only after this initial screening process will Weatherford Laboratories recommend a suite of tests suitable for the state of the cuttings. Depending on sample quality and quantity, a variety of analyses- including geochemistry, mineralogy, elemental analysis, fluid sensitivity, laser grain size, grain density, and biostratigraphy-are routinely performed on cuttings.
