DeGolyer and MacNaughton
Javier Miranda is a Senior Petrophysicist for DeGolyer and MacNaughton, the leading independent consulting firm focused on the petroleum industry since 1936. He works in the Reservoir Studies Division in different world-class projects around the globe. Javier has more than 20 years of industrial experience as a Petrophysicist. Previously, he worked for BP for almost five years as a Reservoir Description and Operations Petrophysicist in three different areas in the Gulf of Mexico, including some of the most prolific fields in the region Thunder Horse, Great White, Mars, Ursa, and Kepler, among others. He was part of a multidisciplinary effort in BP to build several key reservoir models that currently support the area development plan while also being involved in multiple data acquisition, analysis and integration, including whole and sidewall cores, well-logs and fluid samples. Part of his work during his time at BP was published in four internal and external papers. He started his career in PDVSA, the Venezuelan National Oil Company, where he was responsible for single and multi-well petrophysical evaluation, core planning, acquisition and analysis, petrophysical operations and reservoir modeling of clastic and carbonate reservoirs, from heavy oil to gas fields in different postings and basins. Javier earned a BSc from Universidad del Zulia and a MSc from the University of Texas at Austin, both in Petroleum Engineering. He also holds a Diploma in Integrated Petrophysics from the former PDVSA School of Petrophysics (based on former Amoco Petrophysics School). On the academia, he served as Adjunct Professor and Lecturer for Formation Evaluation at Universidad Zamora (Venezuela) for three years and Graduate Research Assistant at the University of Texas at Austin Joint Industry Research Consortium on Formation Evaluation for two years.
Javier is an active member of SPWLA, SPE, AAPG, SEG and HGS with high participation and experience in technical meetings organization, technical editor for publications such as the SPE Reservoir Evaluation and Engineering Journal and SPWLA Today Newsletter and managing and founding SPE and SPWLA sections and groups. He is co-founder of the SPWLA YP global group where he currently serves as Chairman of the board and editor for the SPWLA Today Newsletter, published bimonthly. He is the Industrial Advisor for the SPWLA Austin Chapter. Besides, Javier is past President and Vice-President (VP) of Technology for the SPWLA Austin Chapter (formerly a professional section) and past chairperson and founder of the SPE Southwest Venezuela Section where he received an award from the South America and Caribbean Region for the number of members recruited in the first year of this section. His research interests include Petrophysics, well log analysis, core-log integration, and integrated reservoir characterization while working in multi-disciplinary and multi-cultural environments. Outside of work, Javier enjoys spending time with his family and friends, reading and traveling.
