Oil spills are a major environmental pollutant, affecting the biodiversity of flora and fauna, fresh water and putting on risk the health of indigenous communities in the Peruvian Amazon. Between 2008 and 2018 there were more than 36 oil spills registered. The satellite information extracted from the image analysis of Syntethic Aperture Radar (SAR) can be used to identify oil spills in water bodies, this technology will allow us to obtain spatial, spectral and geometric characteristics, textural differences and physical characteristics such as backscatter levels, to identify and characterize an oil spill in the study area. In the present study SAR images from Sentinel 1A and 1B were used for analyse eight oil spills that occurred in 2016 in the department of Loreto. It was identified that the total area affected for the oil spills analysed is 11.1356 Km2. In the specific case of the double oil spill on 21 August 2016 in Km 54+200 and Km 55+500 at approximately 0.72 Km distance from the Marañon River in Loreto the area affected is the most extensive of 2016 reaching 3.7543 Km2. This type of study is important since it is a way to evidence the damage that these oil spills are causing to the Peruvian Amazon, in addition it is an important tool that quantifies the affected area to be able to define tactics in order to collect the oil and determine environmental remediation strategies.
