Oil and Gas Application Notebook

Significance of the Topic

The accurate analysis of petroleum, natural gas and industrial water is critical for optimizing production efficiency, ensuring product quality, meeting regulatory requirements and reducing operational costs.

Objectives and Study Overview

This document presents an integrated analytical workflow for upstream, midstream and downstream operations in the oil and gas sector as well as for industrial water processes. Key goals include demonstrating method performance for major analyte classes (sulfur, nitrogen, hydrocarbons, metals, anions, cations and amines), validating mobile and stationary phase configurations, and showcasing software tools for data management.

Methodology and Instrumentation Used

• Gas chromatography (GC, GC-FID, GC-MS) and simulated distillation (SIMDIS) for hydrocarbon profiling and calorific value determination
• Inductively coupled plasma optical emission spectrometry (ICP-OES) for trace metal analysis in complex matrices
• Organic elemental analysis (OEA) for nitrogen, carbon, hydrogen, sulfur and oxygen determination in crude and lubricants
• Combustion ion chromatography (CIC) for halides and sulfur species in LPG and crude oil
• Ion chromatography (IC) with conductivity and mass spectrometric detection (IC-MS) for anions, cations and amines in water and solvent scrubbing solutions
• Laboratory Information Management Systems (LIMS) and chromatography data systems (CDS) for sample tracking, result validation and reporting

Main Results and Discussion

• High reproducibility (RSD <1%–3%) for nitrogen analysis in crude oil and lubricants using OEA methods, independent of carrier gas choice
• Trace element recoveries within ±5% for spiked naphtha samples by ICP-OES, enabling ppb-level detection
• Efficient SIMDIS analysis of crude and refined products with ASTM-compliant simulated distillation using TRACE 1310 GC
• Automated CIC separation of halides, sulfate and sulfur species in LPG and boiler water, improving reproducibility over manual methods
• High-resolution IC gradients for separation of heat stable salts, organic acids, anions and cations in refinery scrubbers and cooling water within 20–30 minutes
• Turnkey GC natural gas analyzers meeting GPA, ASTM, ISO and DIN methods for BTU content, permanent gases and hydrocarbon composition with multi-channel configurations
• Integrated informatics enabling real-time process monitoring, data integrity and centralized reporting across upstream to downstream workflows

Benefits and Practical Application

This comprehensive analytics portfolio supports:

• Faster and more accurate decision-making for drill site selection, custody transfer and product quality assurance
• Reduced downtime through preventative maintenance of industrial water systems and scrubbing solutions
• Compliance with environmental and safety regulations via reliable detection of toxic and corrosive species
