Crude oil assay services:

• Crude oil assay testing includes crude oil characterization of whole crude oils and the boiling-range fractions produced from physical distillation by various procedures. The petroleum assay data is used by clients for detailed refinery engineering and crude oil marketing. Feedstock assay data helps refineries optimize the refining process.

Basic petroleum assay evaluations include:

• Atmospheric and vacuum distillations producing distillate fractions and residual bottoms similar to the actual refining process. Crude oil general properties analysis produces data including sulfur content, nitrogen content, viscosity measurements, cold property measurements and metals content. Detailed hydrocarbon analysis of crude oil off-gas is also run.
  

Crude oil assays vary in depth and complexity, dependent upon crude oil type and customer requirements. Intertek labs provide standard assay formatting and custom tailored evaluations. Individual characterizations can be presented in a variety of formats including those capable of being downloaded into certain types of LP models.

The unique molecular characteristics of each crude oil produced means that related assays, analysis requirements and reporting format services are offered by Intertek on a project quotation basis.
