Abstract

Mapping passive seismics in Cusiana and Cupiagua fields has revealed a strong correlation between reservoir dynamic performance and production induced microseismicity. Fluid production/injection causes changes in reservoir pore pressure and, therefore, in local effective stresses. The changes in effective stresses cause natural fracture deformations which, in turn, change local transmissibilities and triggers microseismic events. The interplay of these two latter effects determines the relationship between microseismicity and reservoir dynamics (pressures and fluid saturations among other factors).
