Petromarkers, Inc. is an independent, Petroleum Geochemistry Laboratory that offers comprehensive analysis to the petroleum industry. Our analyses within the fields of Isotopic and Petroleum Geochemistry use analytical techniques such as GC-FID/FPD/TCD, GC/MS, GC/MS/MS, and HPLC/RI/UV. Petromarkers, Inc. offers petroleum and organic geochemistry services as a tool for petroleum exploration and production projects. Services include geochemical interpretation using saturate/aromatic biomarker correlations (source rock-oil, oil-oil genetic correlations), production allocation (reservoir continuity), geochemical inversion studies as well as proprietary and non-exclusive, multi-client regional studies. More specifically, Petromarkers, Inc. offers a wide range of analyses for source rock (TOC, Pyrolysis Rock Eval, Vitrinite Reflectance); and crude oils, bituminous extract of source rocks, seeps, and other related matrices, such as SARA fractionation, WOGC, GC/FID and GC/MS for C15+ saturate and aromatic fractions (Biomarkers), High molecular weight hydrocarbons by HTGC, diamondoid hydrocarbons by GC/MS and GC/MSMS, and bulk and CSIA isotopin analyses in order to identify source, depositional paleoenvironment, maturity, biodegradation, and migration.
