Gas/oil ratios, shrinkage and compositional data all provide you with crucial information about your well or reservoir.

Oil Rig

Having this information available on-site, when you need it, supports your operations, saving you time and money. SGS performs field based compositional analyses using our SGS GC-GOR™ technology and specialized Agilent 7890 Gas Chromatograph system. This innovative system is designed for extended gas and liquid analyses in remote field locations. Using this technology we deliver compositional data you can rely on, based on multiple flash measurements on ultra-small volume samples. The SGS GC-GOR™ system can be used in the field alone, or as part of of an SGS FluidPro PAL™ mobile laboratory.

Benefits of the SGS GC-GOR™ system

The SGS GC-GOR™ system has a number of key features that enable us to provide high quality laboratory analysis data in remote field locations. The electronic temperature control, multiple flash and sample measurements, along with the small sample volumes required allow for repeatable, accurate results, using a process that is easy to perform manually. Through this system we are able to reduce your hydrocarbon inventory using on-site methods, minimizing your sample transport costs and delivering your results in the optimal report turnaround time.
