... are integrated with carbon isotopes, whole-oil gas chromatography, saturates, aromatics, resins and asphaltenes (SARA) analysis and biomarkers in order to detect different variations in fluid composition that may be lead to better understanding of reservoir compartmentalization. Based on these four analyses...

...) strategies. These studies are generated from a series of lab experiments conducted on reservoir fluid samples in high pressure-high temperature (HPHT) lab environments, and commonly matched using Equation of State (EOS) software. Feeding and characterizing the composition of a reservoir fluid in a PVT...

... of geochemical method as the new eye to trace source of well integrity issues and emulates forensic engineering to investigate well barrier failures. Crude and gas compositional analysis from C1 up till C36 carbon chain plays a key role in determining the possible scenarios of leak paths and type of fluid...

... and TEM). The composition of organic deposit samples was investigated using saturates, aromatics, resins, and asphaltenes (SARA) characterization, Fourier transform infrared analysis (FTIR) and Fourier transform ion cyclotron resonance mass spectrometry (FTMS). The sludge sample solubility tests were...

... Abstract A detailed understanding of the composition of sour gas accumulations is essential for facility design and for production forecasting. Compositional data like H 2 S and CO 2 contents, net sales gas volume and condensate gas ratio also form the basis for all project economics...

... within a short period of time. The assessment of the pilot required that all production streams (emulsion and casing vent gas) were metered and frequently sampled to measure their respective compositions. Cross calibration of metered and sampled water cuts was essential in obtaining conclusive production...

... Abstract This paper demonstrates that selecting a gas processing concept that is robust against changes in predicted gas composition during the maturation of (associated) gas projects reduces the risk of schedule delays and cost creep while potentially presenting opportunities to deliver first...

... Abstract Assessing heavy oil composition of a green field, with an accepted level of uncertainty so it can be used for refinery capacity planning is a critical challenge. Knowledge of heavy crude oil properties is vital to understand potential adverse impact on process performance and total...
