Abstract

The Nuclear Magnetic Resonance Technology is a geophysical method developed and applied in the hydrocarbon’s exploration and exploitation. This method is based on the study of electromagnetic responses from different materials and / or structures in the subsoil. These spectral signatures emanate a single-frequency of electromagnetic radiation which can be registered using the stochastic resonance phenomenon. This technology can identify the presence and composition of electromagnetic 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 Electro-Resonance Sounding (SVER), which can show a subsoil vertical perspective pointing to the depth and thickness of layers saturated with interest 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).
