Abstract: Systems and methods include a computer-implemented method for analyzing petroleum samples. Different boiling curves are received that are calculated for a petroleum sample using different analytical speciation techniques. The boiling curves include: 1) a detailed hydrocarbon analysis (DHA) is used for a speciation of light-end components of the petroleum sample; 2) a comprehensive 2-dimensional (2D) gas chromatography (GCxGC) is used for a speciation of a middle distillates range of the petroleum sample; and 3) a high-resolution mass spectrometry is used for a speciation of heavy-end components of the petroleum sample. A compositional coverage of the different analytical speciation techniques for the petroleum samples is determined using the different boiling curves. Each of the different analytical speciation techniques covers a different boiling range and produces a compositional model modeling a breakdown of components in the petroleum sample by carbon number, aromatic ring family, and heteroatom class.

Abstract: Embodiments herein relate to systems and methods for identifying a plurality of components of a petroleum sample. Embodiments further relate to determining respective atmospheric equivalent boiling points (AEBPs) for respective ones of the plurality of components. Embodiments further relate to determining a boiling curve for the petroleum sample based on the respective AEBPs. Embodiments further relate to outputting an indication of the boiling curve for the petroleum sample. Other embodiments may be described or claimed.
