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.

Overview of the Hydraulic Fracturing Test Site 2 (HFTS-2) in the Permian Delaware Basin

Jordan Ciezobka, GTI

Jordan is a Senior R&D Manager at the Gas Technology Institute (GTI) in the Subsurface Technology Group. He has over 15 years of experience in the oil and gas industry, much of it spent working on data-rich integrated diagnostic projects. He is the principal investigator and project manager for the DOE /NETL Hydraulic Fracturing Test Site I & II (HFTS) programs. These are collaborative, field-based integrated diagnostic pilots, focused on environmentally prudent development of unconventional resources. He holds several patents in hydraulic fracturing technology and has authored and co-authored papers on the topic. Before joining GTI in 2010, he held various technical positions at Halliburton. Ciezobka holds a BS degree in Mechanical Engineering from Purdue University.

HFTS-2 Completions Design and State-of-the-Art Diagnostics Results

Matt Jones, Occidental

Matt Jones graduated from Texas A&M University in 2013 with a bachelor’s degree in Petroleum Engineering. His background is in production engineering, completion engineering, and workovers. From 2014-2017, he supported Anadarko’s Eagleford asset in South Texas as a Production Engineer, and his primary focuses where production surveillance, remedial workovers, and artificial lift design and optimization. From 2017-2019, he supported Anadarko’s Delaware Basin asset in West Texas as a Sr. Completions Engineer, and his primary focuses where hydraulic stimulations of unconventional horizontal wells, coiled tubing cleanouts, and other completion-based operations. When Occidental acquired Anadarko in late 2019, he transitioned roles to be a Completions Engineering Supervisor for the Delaware Basin asset. In May 2021, he moved to Occidental’s Worldwide Drilling & Completions Team as a Completions Engineering Advisor, which is his current role where he supports completions company-wide.

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.
