Oil and Gas Application Notebook

Importance of the Topic

Analytical testing in the oil, gas and industrial water sectors underpins process optimization, product quality and safety compliance. Accurate measurement of elements, gases, organics and inorganics guides decisions from exploration through refining and water treatment. Advanced workflows reduce operational costs, improve uptime and support environmental regulations.

Objectives and Overview of the White Paper

This document maps complete analytical workflows for petroleum, natural gas and industrial water applications. It outlines key processes in upstream, midstream and downstream operations and identifies suitable analytical techniques. Practical performance data illustrate reproducibility, sensitivity and ease of use across diverse sample matrices.

Methodology and Instrumentation

A modular approach pairs sample type with optimal technology. Main techniques include:

• Gas Chromatography (GC, GC-FID, GC-MS, GC-HRAM) for hydrocarbon speciation, BTU determination and SIMDIS (ASTM methods)
• Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) for trace metals in crude, condensate and naphtha
• Organic Elemental Analysis (OEA) for nitrogen, sulfur, carbon and hydrogen in fuels and lubricants
• Combustion Ion Chromatography (CIC) for halides, sulfur and anions in LPG and refinery samples
• Ion Chromatography (IC, IC-MS) for anions, cations and amines in water and scrubbing solutions
• High-Performance Liquid Chromatography (HPLC) for aromatics and organic acids
• Laboratory Information Management Systems (LIMS) for data integration and real-time decision support

Main Results and Discussion

• Nitrogen reproducibility in crude and lubricants met ASTM D5291 precision targets with RSDs below 1%.
• SIMDIS boiling point distributions matched ASTM D7169 requirements, enabling accurate cut-point profiling.
• BTU and hydrocarbon profiles of natural gas and NGLs by GC methods met GPA/ASTM standards.
• Refinery gas analyses achieved clear separation of permanent gases, light hydrocarbons and olefins using multi-channel GC.
• Trace halogens and sulfur in LPG by CIC (ASTM D7994) delivered automated prep and high reproducibility.
• Organic elemental spikes in naphtha yielded ≥97% recoveries by cooled-spray ICP-OES.
• Trace organic acids and heat stable salts in refinery water showed reliable resolution on IC columns within 30 minutes.
• Cations and amines in alkanolamine scrubbers were confirmed by IC-MS, offering selectivity for partially resolved species.
• Low-ppt anions in boiler and cooling water were quantified with suppressed conductivity and electrolytic water purification.

Benefits and Practical Applications

Integrated workflows streamline sample throughput, reduce manual intervention and maintain instrument uptime. Automated calibration and data management ensure compliance with regulatory methods. Real-time result evaluation accelerates decision-making in process control, custody transfer, QA/QC and preventive maintenance.
