Abstract

The Nuclear Magnetic Resonance Technology is a geophysi- cal method developed and applied in the hydro carbon’s exploration and exploitation. This method is based on the study of electromagnetic re- sponses from different materials and / or structures in the subsoil. These spectral signatures emanate a single-frequency of electromagnetic radia- tion which can be registered using the stochastic resonance phenomenon. This technology can identify the presence and composition of elec- tromagnetic anomalies due to hydrocarbon in the satellite stage (Satellite Spectrographic). The accurate definition of the boundaries anomalous zone (ac cumulation area) is possible by the Method of formation of short- pulsed electromagnetic field (ECECI) and the Method of Vertical Elec- tro-Resonance Sounding (SVER), which can show a subsoil vertical per- spective pointing to the depth and thickness of layers saturated with in- terest material. This publication aims to show the results of the NUCLEAR MAGNETIC RESONANCE application on Putumayo oilfields located in the blocks: Area Occidental and Area Sur, the total area researched by Satellite Spec- trography in the specifics zones (Blocks: A. occidental, A. Sur and Orito) was 247.5 km2, 129 km2 with the ECECI and SVER methods equivalent to 268% of the original area requested by the client (48 km2).
