Major Projects
During his time at D&M, Salazar has conducted reserves, contingent resources and prospective resources evaluations for clients across the world. He has broad experience across the oil and gas life cycle, from frontier exploration studies in offshore deepwater Suriname and Namibia, to reserves evaluation in mature fields in Ukraine and Indonesia.
Salazar began his career in the industry with Occidental Petroleum in Colombia as a reservoir engineer, where he proposed development drilling, workovers, and water injection optimization activities in the Llanos Basin. He later transitioned into a petrophysicist role, supporting exploration and development projects across basins in Colombia and Ecuador.
As an exploration geoscientist for SierraCol Energy, he was involved in a fully probabilistic technical and economic evaluation of the company’s exploration portfolio and delivered a 5-year optimized investment plan. He also led a multidisciplinary team of geoscientists, land professionals, environmental experts, drilling, and facilities and operations engineers in drilling an exploration well in a socially and environmentally complex area.
