URTeC 2021 Technical Program Themes
Theme 1: Operators’ Forum: Case Studies Highlighting the Multidisciplinary Approach to Exploration, Appraisal, Pilot Tests, and Development of Unconventional Resources
The Operators’ Forum will focus on case studies that illustrate the integration of multiple disciplines, including geology, geophysics, geomechanics, completions engineering, and reservoir engineering, to evaluate complex datasets and improve asset value.

Theme 14: Special Sessions
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, is in the Delaware Sub-Basin. Since the data collected in the R&D program is 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.
