Hydrocarbons in Drill Cuttings

Drilling Mud and Drill Cutting Testing: Measuring Hydrocarbons

  • Test oil levels for overboard disposal
  • Meet requirements for land applications
  • Results in less than 15 minutes
  • Ppm or % hydrocarbon levels

The large amounts of drill cuttings produced in offshore drilling require meeting an allowable limit on total petroleum hydrocarbons (TPH) for ocean disposal. Transporting cuttings to shore is labor intensive, costly, and could cease drilling activities due to bad weather. Limit requirements also must be met for onshore disposal or reuse. To evaluate hydrocarbon levels in drill cuttings or drilling mud, oil is extracted into the solvent for measurement. The InfraCal 2 Analyzer’s capability for multiple calibrations allow for ppm to percent levels.

Whether onshore or offshore, the InfraCal 2 Analyzer can determine if oil levels have exceeded the allowable limit in less than 15 minutes. The InfraCal 2 Analyzer is a compact, fixed-filter, mid-infrared analyzer with no moving parts. Hydrocarbons are measured at 3.4 mm (2930 cm-1). It is rugged and portable, weighing less than 5 pounds, and the user interface is specifically designed for non-technical operators.

The InfraCal 2 TOG/TPH Analyzer is capable of sub-ppm measurements, can store multiple calibrations and has password protection on calibrations and instrument settings.  This updated version of the InfraCal currently used worldwide for oil in water and soil analysis now has increased sensitivity, a multi-language touchscreen user interface and internal data storage.  Data can be exported via USB directly to a PC or to a flash drive.
