Summary:
This paper illustrates a very successful application of an integrated workflow including surface and downhole logging, to unlock the hydrocarbon potential of a thin-laminated, low resistivity pay in South America. Unknown water salinity and undifferentiated resistivity across the interval, made the identification of the pay and the estimation of hydrocarbon saturation very challenging. However, the use of tri-axial resistivity induction allowed to identify the presence of thin laminations and the advanced surface fluid logging (ASFL) system proved the presence of hydrocarbons. The combination of these measurements with high-resolution magnetic resonance, dipole sonic scanning and wireline formation pressure allowed to further define the presence and extension of the hydrocarbon accumulation.
