Compositional changes of diamondoid distributions caused by simulated evaporative fractionation

Autor: Alexander Chakhmakhchev, Nyamaman Davidson, Catherine Pearson, Joanne Sanderson

Publikováno v: Organic Geochemistry. 113:224-228

We simulate and observe the effects of vertical migration on diamondoid composition for a single-phase fluid. A SGS Mini-PVT™ phase behavior cell was used to simulate upward migration of a condensate through multi-stacked reservoirs. PVT cell press

Geochemical Tools to Correlate Light Petroleum and Evaluate Thermal Maturity: A Case Study of Precambrian Condensates from East Siberia, Russia

Autor: Alexander Chakhmakhchev, Vlad Andrus, Alexei Tchistiakov, Olga Shiganova

Publikováno v: Day 3 Wed, October 18, 2017.

Geochemical correlations of light oils and condensates represent an analytical challenge because of low concentrations of the longer chain alkanes and polycyclic biomarkers. In this study, several geochemical techniques are shown to be useful tools f

Geochemical characteristics of Tertiary oils derived from siliceous sources in Japan, Russia and U.S.A

Autor: Masaru Suzuki, Alexander Chakhmakhchev, Amane Waseda, Kuniaki Takayama

Publikováno v: Organic Geochemistry. 27:523-536

Siliceous sourced Tertiary oils from the Circum-Pacific area of Japan, Russia and the U.S.A. have a heavy carbon isotope composition, monomodal n -alkane distributions, and nearly identical regular sterane compositions with a predominance of C 27 hom

Distribution of alkylated dibenzothiophenes in petroleum as a tool for maturity assessments

Autor: Masaru Suzuki, Alexander Chakhmakhchev, Kuniaki Takayama

Publikováno v: Organic Geochemistry. 26:483-489

Aromatic fractions of 64 oil and condensate samples from various basins of the Former USSR were analyzed using GC with a flame-photometric detector (FPD), and GC MS to investigate relative distributions of aromatic sulfur compounds with respect to ma

Biomarker distributions in oils from the Akita and Niigata Basins, Japan

Autor: Masaru Suzuki, Alexander Chakhmakhchev, Noriyuki Suzuki, Kuniaki Takayama

Publikováno v: Chemical Geology. 133:1-14

Oils from the Akita and Niigata Basins, Japan, are characterized by the predominance of C 15 C 17 alkanes, pristane/phytane ratio 27 regular steranes and the presence of C 26 steranes. These are consistent with the marine depositional environment

Aromatic sulfur compounds as maturity indicators for petroleums from the Buzuluk depression, Russia

Autor: Alexander Chakhmakhchev, Noriyuki Suzuki

Publikováno v: Organic Geochemistry. 23:617-625

This study demonstrated that phase state and compositional variations of hydrocarbons in the Buzuluk depression, Russia, are related to maturity levels of Devonian source rocks. Maturity levels of organic matter of source rocks estimated by Rock-Eval

Saturate biomarkers and aromatic sulfur compounds in oils and condensates from different source rock lithologies of Kazakhstan, Japan and Russia

Autor: Noriyuki Suzuki, Alexander Chakhmakhchev

Publikováno v: Organic Geochemistry. 23:289-299

Representative petroleums from the seven basins of Kazakhstan, Russia and Japan were analyzed using gas chromatography with dual FID/FPD and GC/MS. The present study has shown that the deviation in relative concentrations of aromatic sulfur compounds
