[Grupo Dragon, Mexico]

The Domo de San Pedro geothermal field is located, in the state of Nayarit, in central western Mexico. It is developed and operated by Grupo Dragon, the first private company in geothermal generation in Mexico. Until the year 2016, nine boreholes wells have been drilled in the field and currently has an installed capacity of 35.5 MW. It is composed of two backpressure units of 5 MW each and one condensing flash power plant of 25.5 MW. The region of San Pedro is located inside the Compostela graben and center of a structural depression caused by a cross between N-S, NE-SW, NW-SE and E-W faults. This is a complex asymmetrical depression developed during Late Miocene and Pliocene. Our conceptual model has been fed from the data generated in the exploration stage and also already in operation. This paper will describe the 3D conceptual model made by Department of Geoscience to obtain a drill target. The 3D model integrates geology, well data, geophysics, geochemistry, temperature and pressure reservoir, passive seismic, among other data to bring an understanding of the subsurface.
