FTIR and SUVF spectroscopy applied to reservoir compartmentalization: a comparative study with gas chromatography fingerprints results

Analysis of Carbonyl Value of Frying Oil by Fourier Transform Infrared Spectroscopy

“…Fourier-transform infrared FTIR spectroscopy has proved to be a good alternative to standard wet analytical techniques for determining key quality parameters in many fields [12][13][14] . It has the advantages of rapid acquisition of spectral data, is easy to operate and needs no complex sample preparation 15 .…”

Differentiation of weathered oils using infrared indexes and self-organizing maps

“…They had been used to classify road paving bitumens and to evaluate reservoirs continuities and geochemical evolution of oils from individual reservoirs [22,23]. They were: aromaticity index (as a measure of the total amount of C@C bonds, A 1600 /A tot ); aliphatic index (A 1450+1376 /A tot ); branched chains index (A 1376 /A 1450+1376 ); long chains index (A 724 /A 1450+1376 ); aromatic condensation index (A 864+814+743 /A tot ) (as a measure of aromatic C@C bonds); Acarbonyl index (A 1700 /A tot ); sulphoxide index (A 1030 /A tot ); substitution 1 (as a measure of the number of isolated CH groups in multisubstituted rings, A 864 /A 864+814+743 ); substitution 2 (as a measure of the number of 2 or 3 adjacent CH groups in substituted rings, a good indication of three-substituted aromatic rings, A 814 /A 864+814+743 ); substitution 3 (as a measure of the number of 3 or 4 adjacent CH groups in substituted rings, a good indication of di-and mono-substituted rings, A 743 /A 864+814+743 ).…”

A Rapid Method of Crude Oil Analysis Using FT-IR Spectroscopy

“…Many key geochemical advances that facilitate successful oil-oil correlation and oil-source rock correlation include innovations in GC-MS, metastable-reaction monitoring-GC-MS and GC-MS-MS (Peters and Fowler, 2001). Gas chromatography has been extensively used to fingerprint and evaluate reservoir compartmentalisation and connectivity (Larter and Aplin, 1995;Parmenyer et al, 2001), with the aid of star diagrams and other statistical methods of analysis using selected n-alkane ratios (Permanyer et al, 2002).…”
