Oil can be tested to identify the type or age of petroleum. Samples are extracted and diluted in solvent and then measured for their aromatic hydrocarbon content.  This evaluation study highlights the performance using Sitelab’s UVF-TRILOGY analyzer.  The equipment is easy to use and samples take just a few minutes to analyze.  Instructions and training by phone is included when purchasing or renting the equipment. 

 

The proportions of a sample’s GRO and PAH concentrations will vary depending on how old and what type of petroleum contamination is present.  These signatures are then compared to Sitelab's unique database containing the signatures of hundreds of archived reference standards, oils and samples having known petroleum sources.

  

Common Applications:

 

NAPL (non aqueous phase liquids)

Fresh vs. Weathered Fuels

Commingled vs. Single Source Spills

Crude Oil Quality, API Gravity

Octane in Gasoline, Racing Fuel

Jet Fuel Identification

Oil Based vs. Synthetic Drilling Muds

● Coal Tars in Asphalts, Parking Lot Sealcoats

UVF-TRILOGY Performance

The UVF-TRILOGY was designed to replicate and replace Sitelab's UVF-3100 and TD-500D models.  The case studies listed below highlight the accuracy using these instruments for past projects.

Petroleum Tank Farm Site with NAPL

Sitelab's mobile laboratory was used by an environmental engineering firm to test Non Aquous Phase Liquids (NAPL) collected from 40 monitoring wells for their gasoline range and diesel range content.  The site is located along Boston Harbor and once supplied diesel and heavy fuel oil to the region.  The data mapped by the client shows how the oils fluoresced, which helped the client design a recovery system.

Refinery Site with Commingled Oil Plume

An environmental consultant used Sitelab to help dilineate a 100-acre size plume of NAPL at a former oil refinery in Kansas.  Samples collected from 35 monitoring wells were measured for their GRO and DRO content using the UVF-3100D analyzer.  Ratios exhibited in the data show where and what type of contamination exists below the ground.

Crude Oil Production Wells

An oil company in Oklahoma used Sitelab’s laboratory to perform oil forensic analysis testing crude oils from different well sites to determine the percentage of oil content from two formations.  The wells tap into the Mississippi and Chester formations at different depths, thousands of feet deep.  Knowing what type of oil being pumped up is important.  Screening oils on-site using ultraviolet fluorescence is a fast and cost effective tool.  

  See case study

 

Produced Water Treatment Site

A pilot study was performed testing samples contaminated with produced water from several oil well production sites in Wyoming.  The client provides mobile water treatment systems that enable oil and gas companies to recycle and reuse flow back water more efficiently.  Ratios exhibited in the results provides helpful information about the type of oil being treated at each site.
