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.

Determination of petroleum component boiling temperatures

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.

Petroleum composition stitching using boiling curves

A method and a system for creating a reference standard for hydrogen sulfide concentrations in crude oil are described. The method includes receiving a volume of crude oil in a vessel. A hydrogen sulfide gas is flowed from a pressurized gas cylinder to the vessel to form a hydrogen sulfide gas-crude oil mixture. The hydrogen sulfide gas continues to flow from the pressurized gas cylinder to the vessel at a set pressure for a predetermined time to adjust the hydrogen sulfide concentration in the hydrogen sulfide gas-crude oil mixture to a hydrogen sulfide threshold concentration. The flow of the hydrogen sulfide gas into the vessel is stopped.
