      Delia Anne-Marie Androne, Ph.D.,

      Senior Geochemist,

              Summary

  • Senior Geochemist with over 25 years of experience and strong academic and industry background in Geochemistry - both Petroleum Organic Geochemistry and Inorganic Geochemistry - applied in numerous projects overseas.
  • Proven track record of successful geochemical work, as associate professor at Alexandru Ioan Cuza University of Iași, Romania and as a petroleum geochemist / petroleum systems analyst / consultant with the French company Beicip Franlab (IFP Group, Rueil-Malmaison, France) for PDVSA, in Maracaibo Basin, Venezuela and also, for TLC. INVEST, in Bacău, Romania.
  • My expertise with various analytical equipment and subsequent data interpretation, as well as design of well-written reports and pertinent project presentations allowed me to build up a trustful and sustainable relationship with company clients.

              Data interpretation:

  • Pyrolysis Rock-Eval analysis and data interpretation: standard and reservoir modes.
  • Liquid Chromatography (HPLC, MPLC, TLC-FID) - SARA separation analysis.
  • Gas Chromatography - Mass Spectrometry (GC-MS) - molecular analysis of the separate fractions: Saturated and Aromatic (biomarkers, diamondoids and other markers analysis and data interpretation).
  • Elemental Analysis (AAS, LIBS, XRF, ICP-MS, ICP-OES etc.) - for major elements (C, H, S etc.), minor and trace elements (V, Ni, Fe etc.) / Isotope Ratio Mass Spectrometry (EA-IRMS) - isotope analysis / Electron Micro Probe Analyzer (EMPA) and Scanning Electron Microscope (SEM) - analysis and data interpretation.
  • X-Ray Diffraction technique (XRD) - identification of mineral species.
  • Mineral / rock investigation in thin sections (polarized and reflected light).
  • Various other screening methods for source rocks analysis, including Spectral Fluorescence, Organic Geo-thermometers (Vitrinite Reflectance, Thermal Alteration Index of pollen and spores, Conodont Alteration Index). • Good knowledge of other types of analysis (other than geochemical) used to corroborate geochemical characteristics in vue of subsequent integration within Petroleum System Analysis.
  • Lab work skills - GC-MS, Pyrolysis RockEval 6 and XRD equipments.
  • Conceptual skills concerning the integration of the analytical data obtained through the above-mentioned techniques, in order to solve the main targeted problems in Petroleum Geosciences regarding EXPLORATION & PRODUCTION:
  • Design of source rock screening analysis program.
  • Source rock characteristics assessment (kerogen type, origin of the organic matter, deposition environment and maturity, %TOC, HI, OI, PI, hydrocarbon potential).
  • Oil bulk properties (API gravity, viscosity, % S etc.) and chemical & molecular characteristics (SARA composition; oil fingerprint; biomarkers, diamondoids and other markers).
  • Oil-oil and oil-source rock correlations / Stratigraphic correlation (chemostratigraphy).
  • Assessment of oil migration routes.
  • Good knowledge of Unconventional resources – geochemical and mineralogical / lithological evaluation of gas-shale units (expertise in tectosilicates: feldspars, silica; phyllosilicates: micas, clay minerals; carbonates).
  • Assessment of compartmentalization issues within the reservoir / Barriers in vertical flow.
  • Impact of oil mixing (quality lowering and other negative-triggered events, g. asphaltenes flocculation).
  • Impact of heavy NSO compounds accumulation in the porous media (heavy oils, tar-mat etc.).
  • Assessment of oil alterations in reservoir (biodegradation, water washing, evaporative fractionation).
  • Commingled production allocation.
  • Identification / study of completion problems (g. tubing, casing leaking).
  • GEOLOGY and GEOPHYSICS ENGINEERING - Alexandru Ioan Cuza University, Iaşi, Romania (1981-1986: 4+1 years) - bachelor diploma.
