Product Quality and Measurement

Jet Fuel Quality Improvement Team

Worked investigating the root causes for the degradation of jet fuel stability at a refinery.  Conclusions included inadequate treating facilities, poor production control, and inadequate quality control measurement and procedures.   

Gas Measurement Dispute

Performed a preliminary audit of natural gas measurement discrepancies between an unregulated gathering system and an interstate pipeline.  Identified periods that meters were out of service and utilized system balance to estimate deliveries.

Crude Oil Metering Dispute

Investigated alleged tampering with crude oil Automatic Custody Transfer volume and quality measuring devices.  Reviewed common carrier pipeline tariffs, inspected site, and analyzed measurement data. Determined that pipeline company had the right to disconnect the offending shipper.

LPG Pipeline Specifications

Evaluated pipeline tariffs, product specifications, connection agreements, and LPG sales agreements for the export of LPG to northern Mexico from fractionation facilities in West Texas.  Also calculated fractionator feedstock and product economics.



Due to our significant operating experience in both process plants and pipelines, our consultants have expertise in gas and liquid quality specifications and measurement practices.

We have reviewed refinery and NGL fractionation design and operations in order to troubleshoot product quality issues, and conducted reviews of crude oil, petroleum products, and natural gas metering to ensure compliance with tariffs and sales agreements.
