The World Leader In Reservoir Intelligence

The intel gathered and shared by our unique, integrated process and one-of-a-kind team of experts informs the entire life cycle of an asset. Having analyzed nearly 100,000 wells for more than 500 clients in every major play in the world, no one can provide a clearer picture of an asset’s value.

Identify, quantify and produce.

Our sole purpose, the reason we exist, is to drive hydrocarbon reserves and facilitate energy independence. We help our clients identify, quantify and produce their hydrocarbon reserves – unconventional and conventional – without the added expense of running new logs.

A privately-owned, comprehensive global oilfield services company, NUTECH was founded in 1998 by ex-Schlumberger and Numar/Halliburton executives who pioneered Nuclear Magnetic Resonance research and development.

Headquartered in Houston, Texas.

Jorge Viamontes, Ph.D.

Executive Vice President, Chief Operating Officer

Dr. Jorge Viamontes joined NUTECH in 2014 to create the NUVISION reservoir engineering department. He was in addition a principal contributor to the creation and expansion of the Reservoir Intelligence consulting business, which allowed NUTECH to enhance the spectrum of its integrated reservoir characterization and engineering services. Dr. Viamontes has recently taken up the position of EVP, Chief Operating Officer with responsibility for the operational performance of NUTECH.

Dr. Viamontes brings a solid technical foundation that has been created through extensive experience working in assets throughout the world. His career has principally concentrated on the development and optimization of oil and gas reservoirs at every stage of the field life.

Dr. Viamontes graduated in 2000 from the University of Rochester with a Bachelor of Arts degree in Physics and Mathematics. Thereafter, in 2001 he earned a Master of Science degree in Physics at Indiana University. Lastly in 2005 he earned a Ph.D. in Experimental Physics at Brown University.

Prior to joining NUTECH Dr. Viamontes held the following positions:

Lead Reservoir Engineer and Deputy Project Manager in PEMEX’s Cantarell Complex for the consulting firm Quantum Reservoir Impact. In that role he worked on production optimization of the giant oil fields Akal and Sihil. This work mainly concentrated on reducing the production decline rate of Akal through a re-development and optimization analysis. This lead to an executable development plan that realized a series gas-oil gravity drainage opportunities in Akal north, south and KL blocks that brought on stream incremental production not previously recognized by PEMEX.
At Royal Dutch Shell Dr. Viamontes held a number of position with increasing responsibility:
At the Projects and Technology center located in Bangalore, India he was a Senior Reservoir engineer and Lead of the subsurface team to demonstrate 100 MMSTB of new scope for recovery opportunities for the Ekulama field in Port Harcourt Nigeria.
In Shell Gabon he was the Petroleum Engineer responsible for all engineering facets of the Koula (25,000 STB/D) and Bende (gas field for the Gabon LNG project). He also, shared responsibility for operating the Toucan field (18,000 STB/D) and Gamba/Ivinga field (6,000 STB/D). In this role Dr. Viamontes developed and brought on stream a green field and through a series of re-development and appraisal activities helped extend the life of some of the largest brown fields in Gabon.
At the Bellaire Technology Center Dr. Viamontes worked as a Petroleum Engineer - Principal Investigator on a number of coded projects with miscible and immiscible flood experiments. This work enabled Shell to improve field recovery and produce from previously technology-locked resources. In addition it was the source of a patented novel displacement process, which Dr. Viamontes is a co author.
