Geochemistry

Weatherford Laboratories offers complete analytical and interpretive services in the field of organic geochemistry. These services include rock and oil analyses ranging from screening analyses such as total organic carbon (TOC), Programmed Pyrolysis, and vitrinite reflectance to a full range of detailed analytical services including mud gas composition, fingerprinting of rock extracts and oils, carbon isotopes, and biomarker assessments. In addition we offer exclusive services in compositional kinetics, pre-test API, viscosity, pour point, GOR, and oil-water saturations predictions. We also offer applied research capabilities in organic geochemistry.

Our specialized services in exploitation include pay zone identification and confirmation, and oil quality assessment prior to well completion. Assessment of reservoir continuity, production allocation, and EOR evaluation are also available using oil samples and require no well shut-ins.

Our custom designed MPLC separation aims at obtaining high quality saturates and aromatics, while maintaining the lighter components for mass spec analyses. Oils and extracts are separated by Medium Pressure Liquid Chromatography into saturate and aromatic fractions for subsequent biomarker analysis by GCMS.
