What are the oil or gas properties (viscosity, API gravity, sulfur, waxiness)?
• Directly measure the bulk properties of oils from nearby fields or from the discovery well (e.g., API gravity, %S, pour point, oil viscosity) and perform gas chromatography analysis to allow characterization of post emplacement alteration history. • Directly measure basic gas properties of gas from nearby fields or from the discovery well. Gas composition data include abundance and distribution of hydrocarbon gases, inert gases such as CO2 or N2, unusual supplemental byproducts such as helium, and deleterious species such as H2S and mercury. In addition, commercial gas properties such as gas heating value in BTU/ft3, mixed LPG potential, and condensate yield should also be measured. • Predict oil or gas properties indirectly from knowledge of source type, thermal maturity, and secondary alteration (e.g., biodegradation, water washing, and preferential gas loss) when fluid samples are not available for direct analysis.
