Geochemistry of Oil Fields, East Java Basin: Biomarker Characterisation

Crude Oil Geochemistry Dependent Biomarker Distributions in the Gulf of Suez, Egypt

Regional Surficial Geochemistry of the Northern Great Basin

The regional distribution of arsenic and 20 other elements in stream-sediment samples in northern Nevada and southeastern Oregon was studied in order to gain new insights about the geologic framework and patterns of hydrothermal mineralization in the area. Data were used from 10,261 samples that were originally collected during the National Uranium Resource Evaluation (NURE) Hydrogeochemical an...

Gas Geochemistry of the Dogger Geothermal Aquifer ( Paris Basin , France )

The low enthalpy program developped in the Paris Basin provides the opportunity for studying the gas geochemistry of the calcareous aquifer of the Dogger. Hydrocarbons and C02 are mainly biogenic, He displays high concentrations. He, Ar and N2 have multiple origins (radioactive decay, atmospheric migration, biochemical processes). The distribution of the gases in the zones of the basin varies i...

Pre-drill Groundwater Geochemistry in the Karoo Basin, South Africa.

Enhanced production of unconventional hydrocarbons in the United States has driven interest in natural gas development globally, but simultaneously raised concerns regarding water quantity and quality impacts associated with hydrocarbon extraction. We conducted a pre-development assessment of groundwater geochemistry in the critically water-restricted Karoo Basin, South Africa. Twenty-two sprin...

Exposures and cancer incidence near oil fields in the Amazon basin of Ecuador.

OBJECTIVES To examine environmental exposure and incidence and mortality of cancer in the village of San Carlos surrounded by oil fields in the Amazon basin of Ecuador. METHODS Water samples of the local streams were analyzed for total petroleum hydrocarbons (TPHs). A preliminary list of potential cancer cases from 1989 to 1998 was prepared. Cases were compared with expected numbers of cancer...
