10:00 - 12:30
Workshop A: Innovations in Well Design Selection and Adjusting to Real-World Operational Constraints

Workshop Leader: George Vassilellis, Independent Consultant,

Through a mix of presentations, discussion and interactive exercises, this workshop will give Engineers, Managers and Directors the focused opportunity to learn and share innovations in adjusting completion design based on actual well performance, economic drivers and outcomes from pilot programs. George will bring real use-cases to the fore, encourage critical thinking and delve into some exciting work that’s being done in completions design to improve ROI.


  1. Accelerate the learning curve: Improved geology, engineering and big data for better results, faster
  2. Adopting to the sweet spot – Adjusting design and operations depending on external economic pressures
  3. Innovation and piloting: Selecting and engaging innovation through screening, piloting, best piloting to not interfere with operations

George Vassilellis, Independent Consultant,

George has over 30 years of experience in geology, reservoir engineering and oil and gas field operations at both operating and consulting companies. He specializes in unconventional resource assets and thermal EOR and has also contributed to the commercialization of major upstream projects globally. Additionally, he has published over 25 technical papers and co-authored textbook materials in unconventional resource exploitation and development.

Prior to his current endeavours, George spent 4 years at Repsol as a senior technical advisor of the US based Technology Hub, a bridge between strategic research and field operations, developing leading technology in the challenging mid-continent.

Previously he was a senior manager with Gaffney, Cline & Associates (GCA) that was acquired by Baker Hughes in 2008. George has been a key technical contributor at Baker Hughes where he was named a Shale Engineering/Reservoir Subject Matter Expert. Before that he was with SI International (presently MHA Petroleum Consultants) in California and before that with Richardson Operating Company, an independent based in Denver, Colorado.

George earned a BSc in Geology from Aristotle University in Greece and a MSc in Petroleum Engineering from Colorado School of Mines, and he is a registered Professional Engineer (Petroleum) since 2003.

Since mid 2016 he is a Managing Director of NITEC Pegasus LLC, a niche consultancy focusing on implementing predictive models into the appraisal of unconventional resources.

13:30 - 16:00
Workshop B: Produced Water Treatment: Advances in Regulations, Technologies, Cost Efficiency & Management for Reuse

Workshop Leader: Berna Hascakir, Assistant Professor, TEXAS A&M UNIVERSITY Workshop Leader: Dan Mueller, Director, Natural Gas Exploration and Production, Environmental Defense Fund

Water management continues to be a core challenge for the unconventional completions community. This workshop will enable you to weigh up the financial, operational and environmental impacts of water treatment strategies being implemented across key basins in the US at a time when brackish water levels are falling, which is putting urgency on water reuse.

Participate in this workshop to learn about:

  1. The evolution of the minutiae of regulatory guidelines and enforcement implications for produced water injection and disposal
  2. Exploring the costs and suitability of different water treatment technologies
  3. Minimizing the environmental impacts of produced water

Session A

  • An update on federal and state regulations regarding produced water reuse and recycling
  • Deployed and cutting edge robust treatment technologies under development to treat produced water for potential discharge or use outside the upstream oil and gas sector
  • Exploring the costs and suitability of thermal and membrane treatment technologies in specific situations

Session B

  • Examining the variance of produced water quality depending on water injection processes
  • Reducing the environmental impacts of produced water by investigating the sources of produced water contamination
  • Engineering better hydraulic fracturing fluids for reinjection purposes
  • Environmental impact studies

Berna Hascakir, Assistant Professor, TEXAS A&M UNIVERSITY

Berna Hascakir is an assistant professor and the holder of Stephen A. Holditch Faculty Fellow at Texas A&M University in the Petroleum Engineering Department. She pursued postdoctoral studies at Stanford University in the Energy Resource Engineering Department and worked for Schlumberger in Venezuela, UK, and Colombia as a senior Heavy Oil Reservoir Engineer. Her research interests include thermal enhanced oil recovery, flow insurance problems due to asphaltenes precipitation or emulsion formation, environmental impact of oil extraction from unconventional reserves, and water-rock interaction.

She holds B.S. and M.S. degrees from Dokuz Eylul University in Environmental Engineering, and a Ph.D. degree from Middle East Technical University in Petroleum and Natural Gas Engineering. She has authored and coauthored more than 100 technical papers. She is the receipt of the International SPE Junior Faculty Research Grant in 2014 and the International SPE Innovative Teaching Award in 2015.

Dan Mueller, Director, Natural Gas Exploration and Production, Environmental Defense Fund

Dan Mueller is EDF’s Director, Oil and Gas Exploration and Production with his efforts focused on evaluating and developing strategies for addressing environmental impacts of natural gas upstream operations including well drilling and construction, hydraulic fracturing, surface infrastructure, and water and waste management.  Dan is a registered professional engineer with over 35 years of experience in the environmental field.  He has applied his background and experience to a wide-range environmental issues including: water resources evaluation and management; industrial waste management and disposal; and contaminant fate and transport in surface water, groundwater, soil, and sediment.
