This research focused on the determination of the allocation percentage to the soil mesofauna generated by the application of the techniques of Induced and spontaneous effect of microseismic, used for oil exploration in the Amazon. For the analysis of soil mesofauna was used as bioindicators to Arachnids, Centipede (Arthropods) and worms (Anelida), to the effect varieties three study areas were established; one at each point of application of the techniques of induced effect and spontaneous effect of microseismic, and a third made at a point equidistant from the two previous comparative measure as state control and soil conservation mesofauna in the sector. the methodology of “Sampling Cruz” which consists in tracing two transects crosshair (+) of 51m each was used in each study area, where 10 sampling sites 1m² each, separated 5m they settled away, where five blocks 20x20x20cm extracted soil, giving a total of 20 sampling points per area studied, giving a total of 100 quantized blocks. In the case of the application areas of microseismic, the point of intersection of the transects was located in the center of implementation of activities. Comparing percentage between the two techniques microseismic involvement mesofauna the soil, on the reduction of specimens, it was determined that in the area of application of the technique of Spontaneous Effect decreased 39%. While in the area of application of the technique effect induced mesofauna the soil it was reduced by 61%. As the technique of induced effect causing greater involvement by 22%.
