Reliable dating of sediments has several applications in petroleum systems analysis (PSA), such as improving our basin models (e. g. subsidence rates) and geochemical interpretations (e. g. age-diagnostic biomarkers).

This technical note summarizes the main results from an article accepted for publication in the SEG-AAPG Interpretation Journal (Davison and Cunha, in press), where we used a relatively rapid 1-D pseudo-well modelling approach to assess the prospectivity of the Burgos Basin and Perdido Fold Belt, in the deep…

The hopane and sterane biomarkers are among the most extensively used compounds in petroleum geochemistry. Whilst the various diagenetic reactions that convert biologically-derived sterol lipids to sterane biomarkers during sediment burial were well established back in the 1980’s (Mackenzie et al.

Using geochemical data contained within IGI’s Norwegian Sea Geochemical Database (compiled from released data on the Norwegian Petroleum Directorate’s website), a regional geochemical interpretation report has been produced which ventures, in part, into the potential for Cretaceous source rocks and generated hydrocarbons in the deeper regions of the…
The latest in our series of Technical Notes has been issued to coincide with the first official release of our newly designed p:IGI+ software, and explains the improvements in the data model for dealing with SARA (oil/extract bulk compositional) data. [DownloadInfo id="22"]

Coals are characterised by an abundance of organic material, typically having total organic carbon (TOC) contents exceeding ca. 35wt%.
IGI’s Barents Sea Geochemical Database contains geochemical data compiled from all relevant reports available on the Norwegian Petroleum Directorate’s website (now updated to the end of 2015), and has been used as the basis for a comprehensive regional geochemical interpretation report (IGI Ltd. , 2015).
Many lacustrine-sourced oils of different ages and from different parts of the world are observed to be waxy, containing high proportions of long-chain n-alkanes, typically showing a slight predominance of odd carbon number chain lengths (Fig. 1).
