Neil McDonald has more than 20 years of extensive commercial experience across the energy and minerals sectors in multiple Australian states. He has been involved from greenfield exploration to early development in projects across Queensland, Northern Territory and South Australia. He has worked on and helped commercialise some of Australia’s largest exploration projects for private and public companies. As a commercial lawyer, Neil has a strong legal grounding in commercial and regulatory compliance in the resources industry. Neil is a graduate of the Australian Institute of Company Directors.



Roger Cressey has more than 35 years of experience in the resources industry, predominantly in gas exploration and production. Roger has held CEO, COO and other executive roles within upstream and downstream operations across Australia, in Queensland, the NT and before that PNG. He has also held senior roles with companies active in Indonesia and Uganda. Roger’s strengths lie in managing multi-discipline teams, strategy development and delivery. He has a strong focus on engagement with both external and internal key stakeholders.



Billy Hadi Subrata has 20 years of experience working with Australian and international energy operators across multiple basins in Australia, New Zealand, East Africa, and Papua New Guinea. A petroleum and reservoir engineer by background, Billy has developed a substantial skill in both exploration and development mainly for reservoir simulation and modelling, field appraisal and development planning, reserves and resources estimation, project management and economics, subsurface to surface integration, hydrogen, and energy transition. Billy is a Qualified Petroleum Reserves and Resources Evaluator (QPRRE) and a member of SPE and Engineers Australia.

Abstract

In October and November 2023, Gold Hydrogen, an ASX listed natural hydrogen explorer, drilled Ramsay 1 and Ramsay 2, the first natural hydrogen exploration wells in Australia. Twinning an historic well, the Ramsay Oil Bore 1 well in PEL687 in South Australia, the objective of the Ramsay 1 and Ramsay 2 wells was to find movable naturally generated hydrogen in the subsurface and establish the presence of a commercially attractive natural hydrogen resource base. This paper highlights some of the learnings from the process of designing and executing these natural hydrogen exploration wells and how the initial hurdles of demonstrating the presence of a hydrogen resource were overcome during the drilling phase. Using modified standard drilling technology and dedicated hydrogen detection tools (calibrated real time mud gas analysis), Gold Hydrogen has shown that exploration for natural hydrogen resources can be done safely and cost effectively. The main learnings included the application of a calibrated hydrogen detection methodology to derive a pseudo hydrogen saturation log and the successful selection of drilling mud and casing compliant with long term hydrogen exposure. As global drilling for natural hydrogen is still in its infancy, these modifications to the exploration well design and execution could have a significant impact on future drilling for this highly attractive carbon free energy source. With a program of seismic data acquisition and follow-up wells planned for 2024, Gold Hydrogen is leading a group of Australian natural hydrogen explorers, who are trying to unlock commercial natural hydrogen resources in the world.
