Course Content

The Hydraulic Fracturing Test Site (HFTS) Program is a research and development (R&D) partnership sponsored by the U.S Department of Energy, National Energy Technology Laboratory (DOE-NETL) and major and independent operator and service companies, managed by the Gas Technology Institute (GTI). The objectives of the HFTS program are to diagnose and understand the hydraulic fracturing process for field development optimization in Unconventional Resources, minimize their environmental impacts by reducing the number of new wells required for effective resource recovery, and improve extraction economics to expand the economically viable resource at increasingly lower commodity prices. A unique aspect of the test sites is the drilling of research wells dedicated to coring through the created hydraulic fractures thus directly measuring fracture locations, fracture quantity, proppant concentrations and other data.

There are currently two test sites in the program, both in the Permian Basin. HFTS-1, operated by Laredo Petroleum, is located in the Midland Sub-Basin, and was the subject of an URTeC Invited Session in 2018. HFTS-2, operated by Occidental Petroleum, is in the Delaware Sub-Basin. Since results of the R&D are confidential to the program sponsors for a period of 2-years, early results from HFTS-2 are just now becoming publicly available and will be the subject of the presentations in this session.

Gustavo Ugueto, Shell Exploration & Production Company

Gustavo Ugueto is Shell’s Fiber Optic Regional Deployment coordinator for the Americas and Principal Petrophysicist for Shell’s Unconventional Technology Organization. In 1982, he received a degree in Geological Engineering from Universidad Central de Venezuela. Gustavo began his career as Petrophysical Engineer at Petroleos de Venezuela in 1981, later joining Shell International in 1988 where he has worked as Petrophysical Engineer, Section Head of Petrophysics and Discipline Head of Petrophysics in The Hague, London, Nigeria and Brunei respectively. He transferred to Shell in the USA in 1997 where he worked in several exploration and development projects in the Shelf and in Deep Water Gulf of Mexico (Auger and Mars-Ursa Basin). Starting in 2005 he began his works on the development of Unconventional Tight Gas Sands and Shales Reservoirs as a lead Petrophysicist, Assets Technology Coordinator and Geoscience Advisor for multiple exploration and development assets in the US-Rockies, including Pinedale. During this time, he led multiple efforts aimed at the integration of frac-diagnostics and modeling and has participated in the installation and interpretation in most of Shell’s Fiber Optic deployments in Unconventionals (about 50 wells). In 2010, he became Shell’s Global Principal Technical Expert (PTE) for Data Acquisition and Special Processing within Petrophysics. He is currently the Focal Point for Frac Diagnostics within Unconventionals, concentrating on Fiber Optic development and data integration. Throughout his career Gustavo Ugueto has participated in several projects involving collaboration between academia and industry. He participated as industry advisor in the USGS/Stanford University San Andreas Fault Observatory at Depth (SAFOD). He led the instrumentation and Fiber Optic interpretation of wells in GTI Hydraulic Fracturing Test Site #2 Consortium in the Permian Delaware Basin and more recently he is co-Pi in a University of Texas Austin project in the EGS FORGE in Utah.

Novel Geochemistry Determined From High Pressure, High Temperature Simulation Experiments of Hydraulic Fracture Test Site 2

Djuna Gulliver, NETL-DOE

Dr. Djuna Gulliver is a research scientist for the National Energy Technology Laboratory (NETL), Department of Energy. Her expertise is in geochemistry and geomicrobiology in energy and energy-impacted environments. She has 7 years of experience investigating the biogeochemical processes in unconventional oil and gas reservoirs and infrastructure. She utilizes next generation sequencing coupled with bioinformatic analysis to characterize the abundant microbial taxonomy, potential metabolic capability, and microbial activity of these natural and engineered systems. She couples this biological data with geochemical profiles to gain insight on dynamic reactions that affect oil and gas productivity. Dr. Gulliver also is currently analyzing the microbial communities in other energy systems, such as carbon storage reservoirs, acid mine drainage, coalbed methane reservoirs, and novel waste-to-product technologies. Djuna Gulliver has a Ph. D in Environmental Engineering from Carnegie Mellon University, a Master’s Degree in Environmental Engineering from Johns Hopkins University, and a Bachelor’s Degree in Chemical Engineering, Geology, and Geophysics from University of Minnesota.
