Title

Geochemical Data for the Olla and Nebo-Hemphill Oil Fields, Louisiana (NERC grant NE/L002612/1)

Abstract

Formation water geochemistry and gas geochemistry from 6 wells in the Olla Oil Field and 7 wells in the Nebo-Hemphill Oil Field Louisiana (Longitude range: -92.2297 to -92.1487, Latitude range: 31.83128 to 31.56586.), sampled in 2015. Formation water geochemistry for cation and anions and in mmol/l and ppm, these were measured at an internal ExxonMobil facility. Casing gases were used to make the remaining measurements. Stable noble gas isotopes (He, Ne, Ar, Kr, Xe) were measured at the University of Oxford Noble Lab for ratios and abundances (in cm3(STP)/cm3). Stable C isotopes of CO2 and CH4 and C2, C3 and C4 alkanes in ‰ VDPB as well as their mol% of the casing gas were measured by Isotech Inc.. Methane clumped isotopes are given as Δ12CH2D2 and Δ13CH3D and were measured at the California Institute of Technology. Where no data is present, no measurements were taken for that well. N.D. refers to not detectable.

Noble gas samples were collected in Cu tubes and analysed by mass spectrometry in the Noble Lab at the University of Oxford. Clumped methane and stable isotope samples were collected in pre-evacuated gas cylinders and analysed by mass spectrometry at the California Institute of Technology and Isotech Inc. respectively.
