“…Although high pressure and low temperature are the preferred operating conditions for most CO 2 SFE systems, high temperature appeared to increase recovery of hydrocarbons from reservoir. The reasons for improved hydrocarbon recovery are that (1) high temperatures increase desorption kinetics and solubility of compounds, leading to enhanced CO 2 solvent penetration to solid matrices with high diffusion coefficients [18] and (2) high temperatures reduce oil viscosity. The extraction of petroleum by CO 2 SFE is selective, preferentially recovering non-polar substances.…”

“…Another unique thing about SFE is that selective extraction is also possible, it has been found to be a useful tool to study speciation of extractable hydrocarbons (Furton et al 1999). Supercritical fluid extraction (SFE) with carbon dioxide has been successfully applied to the extraction of organic compounds from petroleum source rocks (Monin et al 1998;Hopfgartner et al 1990;Ashraf-Khorassani et al 1992;Greibrokk et al 1992;Jaffe et al 1997;Furton et al 1999;Akinlua et al 2008). The use of SFE method for geochemical characterization of petroleum source rocks has been limited.…”

A geochemical evaluation of Niger Delta organic matter was carried out using supercritical fluid extraction (SFE) sample preparation procedure. Comparison of geochemical significance of gas chromatographic data of rock extracts of SFE with those of Soxhlet extraction method from previous studies was made in order to establish the usefulness of SFE in geochemical exploration. The assessment of geochemical character of the rock samples from the comparison and interpretation of other geochemical parameters were used to give more insights into understanding the source rocks characteristics of onshore and shelf portions of the Niger Delta Basin. The results of the gas chromatographic (GC) analysis of the rock extracts across the lithostratigraphic units show that Pr/Ph, Pr/nC 17 , Pr/nC 18 , CPI and odd/even preference ranged from 0.07 to 12.39, 0.04 to 6.66, 0.05 to 13.80, 0.12 to 8.4 and 0.06 to 8.12, respectively. The Rock-Eval pyrolysis data and geochemical ratios and parameters calculated from the GC data showed that most of the samples are mature and have strong terrestrial provenance while a few samples have strong marine provenance. The few marine source rocks are located in the deeper depth horizon. Pr/Ph and standard geochemical plots indicate that most of samples were derived from organic matter deposited in less reducing conditions, i.e. more of oxidizing conditions while a few samples have predominantly influence of reducing conditions. The results of trace metal analysis of older samples from Agbada Formation also indicate marine and mixed organic matter input deposited in less reducing conditions. The results obtained in this study are comparable with those obtained from previous studies when Soxhlet extraction method was used and also indicated the presence of more than one petroleum systems in the Niger Delta.
