Preface
TheAfro-AsianAssociationofPetroleumGeochemists(AAAPG)successfullyheldthe6thInternational
ConferenceonPetroleumGeochemistryandExplorationintheAfro-AsianRegionduringOctober12–
14 in Beijing. The conference was organized by China National Petroleum Corporation (CNPC) and
co-organizedbyChineseAcademyofSciences(CAS).233delegatesfrom23countriesofAsia,Africa,
Europe,NorthAmericaandAustraliaparticipatedintheconferenceandthisconferencewasremarkedas

they were Mr. K. Chandra (India), Chairman of the Fifth Executive Council ofAAAPG; Prof. Ping’an
Peng(China),ViceChairmanoftheFifthExecutiveCouncilofAAAPG;Dr.C.M.Ekweozor(Nigeria),
ViceChairmanoftheFifthExecutiveCouncilofAAAPG;Prof.ShuichangZhang(China),Memberof
theFifthExecutiveCouncilofAAAPG;Dr.K.Kagya(Tanzania),MemberoftheFifthExecutiveCouncil
ofAAAPG; Dr. E. Subroto (Indonesia), Member of the Fifth Executive Council ofAAAPG and some
world-known scholars including Prof. D.W. Welte (Germany), Prof. J.M. Moldowan (U.S.A.), Dr. L.R.
Snowdon(Canada),Dr.S.George(Australia),Dr.W.G.Dow(U.S.A.),Dr.L.H.Nilsen(Denmark)andDr.
MaowenLi(Canada).
The talks and papers presented to this conference covered varieties of research fields including
(1)geochemistryonexplorationinnewlyprospectingareasandontheformationofgiantoil/gasfields;
(2)petroleumsystem;(3)basinmodeling;(4)dynamicsofhydrocarbongenerationandcarbonisotopes;
(5) geochemistry on source rocks and oil-source correlation; (6) geochemistry of natural gases and the
biogenicgas;(7)oil/gasexpulsionandprimarymigration;(8)moleculargeochemistryandbiomarkers;
(9)organicpetrology;and(10)therelationshipbetweenpresentorpaleo-geothermalfieldsandhydro-
carbons.These topics, on the whole, are involved with nearly all the hotspots and frontiers of current
