Biography

Deepankar Biswas has over fifteen years of hands-on experience in industry and research. He comes with a diverse background in reservoir simulator development, application, traditional reservoir engineering, computational finance, development of derivative pricing tools, reservoir economics, real options, software engineering and other petroleum engineering areas of underbalanced drilling and production optimization.

His expertise spans integrated, full-scale and/or sector, heterogeneous (clastics, carbonates, naturally fractured), Black-Oil/Compositional (Eclipse, Arion/Pegasus, VIP, IMEX/GEM, UTCHEM, UTCOMP, GCOMP, eRes) reservoir simulation studies for field development plans (horizontal wells, infill drilling, redevelopment/recompletion activities) under various drive mechanisms (immiscible and miscible).

Geographically he has worked in fields worldwide e.g. Middle East (e.g. Fahud, Nimr A, Bu Hasa), India (e.g. Bombay High, Ankleshwar), Latin America (e.g. Camisea), Europe (e.g. Tempa Rossa) and continental United States (e.g. Rojo Caballos, host of gas fields is Oklahoma, Texas, Arkansas and Kansas).

He had previous tenures with such companies as Mobil Oil, Oil and Natural Gas Commission, TXU, and DeGolyer and MacNaughton. More than ten technical publications and two book chapters on real options reflect his contributions to the archival literature.

Deepankar has a Ph.D. and M.S. from the University of Texas at Austin and an undergraduate degree from the Indian School of Mines, all in Petroleum Engineering. He also received a Certificate in Corporate Finance from the Cox School of Business, Southern Methodist University. He is an active member of Society of Petroleum Engineers and has been a technical editor for SPEJ. He is a professional registered engineer in the state of Texas.

Projects


-Rhourde Nouss, Algeria
Full-field compositional model conversion from GEM to VIP for three fields with approximately 150 wells.

-Dovletabad, Turkmenistan
Compositional model for a large gas field with more than 300 wells and 25 years of history. History matched and predicted field performance under various forecast scenarios to meet contractual gas deliverability obligations.

-Onshore Oil Field, Oman
Three phase, dual porosity Black Oil model of this fractured carbonate field with complex geology. Developed plan to investigate the feasibility of UBD for fracture characterization and drill past fracture corridor to tap bypassed oil.

-Onshore Oil Field, Abu Dhabi
Three phase, compositional model for this tight carbonate field. Investigate feasibility of drilling the gas injectors underbalanced to increase injectivity, efficiency (less number of injectors) and reduce workover delays.

-Onshore Oil Field, Oman
Three-phase Black Oil Model of this Darcy reservoir with active bottom water drive and high viscosity ratio. Investigate the effect of fracture shutoff on the onset of watercut.

-Host of domestic USA gas fields
Perform reservoir engineering and simulation of these fields (mostly sandstone, gas fields) to examine their production potential and eventual equity participation (working interest).

-Tempa Rossa, Italy
Compositional, naturally-fractured model of this thick, tight limestone formation to investigate its potential for Mobil to actively participate in field development.

-Camisea Field, Peru
Compositional, naturally-fractured model for this gas-condensate reservoir to analyze its deliverability potential and feasibility of meeting customer demands.

-Anschutz Ranch, Wyoming
Three-phase compositional model of this mature domestic oil field to assess the viability of infill and/or multi-lateral drilling.

-Rojo Caballos, West Texas
Perform both traditional reservoir engineering and sector simulation model study to prescribe re-completion/re-perforation strategies to improve ultimate recovery from the field.

-Bombay High North and Ankleshwar, Gujarat
Perform reserves estimation, decline curve and material balance analysis to identify drive mechanisms and associated recovery factors.

-Simulator Development, Mobil E&P
Lead technologist in a multidisciplinary team to develop Mobil’s proprietary simulator (ARION). Researched and incorporated the naturally fractured model in a C++ framework of the compositional, multi-phase, fully-implicit reservoir simulator.
