SGS provides complete compositional analyses services for upstream exploration and production utilising industry-standard methods. We follow rigorous calibration procedures to generate detailed compositional data on both atmospheric and pressurised samples.
SGS compositional analyses services
We offer an extensive network of state-of-the-art laboratories and high-quality analyses. Our services include a proprietary flash system called the Mini-GOR™, which was developed by SGS for analysis of pressurised oil, gas and brine samples. This system accurately determines GOR (Gas-Oil Ratios), GWR (Gas-Water Ratios) and CGR (Condensate-Gas Ratios) along with oil, water and condensate shrinkage factors. The compositions of the flashed hydrocarbon products are measured with conventional gas chromatography (GC) in accordance to GPA standard methods. Brine (also referred to as produced water) ionic concentrations are determined by ion-chromatography (IC). Bulk properties, such as water pH, total dissolved solid (TDS), water-in-oil, molecular weight and density are measured to ASTM or other industry-standard methods.
Through our compositional analyses services we provide:
- Innovative Mini-GOR™ technology for onsite GOR, GWR and CGR analyses
- Extended compositions of oil to C36+ by capillary GC, GPA method
- Extended compositions of gas to the last detectable component, GPA method
- Water compositions by titrations and ion chromatography (IC)
- Bulk sample properties by industry-standard methods
High resolution, high quality compositional data gives you the detailed breakdown of components in the crude oil or gas that will be required by engineers and chemists throughout the life cycle of your well. This data is essential for establishing the value of your hydrocarbon reserves, predicting future performance of your wells, designing transport and process systems, and establishing the market value of your oil and gas production.
