Geologist with eighteen years of Oil and Gas industry experience, international and domestic. I enjoy interpretation from basin to field level stratigraphy and structural geology, construction of 2D and 3D reservoir frameworks for development, exploration, business development and new ventures purposes, as well as mentoring and collaborating in multidisciplinary teams. Oil and Gas experience in the following areas: Rocky Mountain basins in Colorado and Wyoming. Permian / Midland basin. California, San Joaquin, and Ventura Basins. Open to explore new opportunities of advancement in other disciplines such as digital transformation and emerging technologies, renewables and sustainability.
