Our Australasian Experience

Jonathan is Chief Executive Officer of ERCE. A geoscientist by background, Jonathan has extensive experience in new business development, M&A, exploration, appraisal, development and production operations gained over 20+ years at Woodside Energy and Ophir Energy. As Director of Subsurface at Ophir Energy Jonathan was responsible for the delivery of all geoscience, exploration and reservoir management activities across Ophir’s global portfolio. He has worked across a diverse range of geological and geographic environments including West, North and East Africa, SE Asia, Australia, and Central America. Jonathan has deep experience of Production Sharing Contracts, Joint Operating Agreements and associated Joint Venture Management activities in a variety of regulatory regimes.

Jonathan holds an Executive MBA from the University of Western Australia, a PhD in Petroleum Geology from University of Adelaide, a MSc Petroleum Geology from University of Aberdeen and a BSc in Geology and Applied Geology from the University of Glasgow. He is a member of PESGB, PESA and currently Treasurer of the Energy Group of the Geological Society of London.

Carl has over 25 years of sedimentological and sequence stratigraphic experience working with E&P companies on exploration, development and producing assets.

Carl has collaborated on projects with companies including; Shell, OMV, ConocoPhillips, Murphy, BHP, Soco, Cairn Energy, Inpex, Woodside and ENI, in sedimentary basins ranging from West Africa, India, SE Asia, Papua New Guinea, Australia and New Zealand. His expertise lies in a multidisciplinary approach, tying in core-based studies with high-resolution image data and sequence stratigraphic analysis. He has worked both siliciclastic and carbonate systems, with environments of deposition (EOD) ranging from fluvial, estuarine systems, fluvial- and wave-dominated deltaic systems, shallow water pinnacle reef and deep-marine ramp carbonate systems, along with slope- to basin-floor fan turbidites.

Over the past twenty years Susannah has held both Exploration Geophysicist and Development Geophysicist roles and has been involved in multiple interpretation and mapping projects primarily in Australia including Cooper Basin, Perth Basin and Northern Canarvon Basin. She has broad geoscience experience and has experience in all phases of oil and gas exploration with Chevron, Cooper Energy, Arc Energy and Santos. This includes gravity, magnetic and seismic geophysical survey acquisition, processing, interpretation and static modelling for both exploration and development projects. She has evaluated and risked multiple exploration prospects as well as worked up detailed, multi-well field development plans and infill well projects. Susannah has particular expertise in structural seismic interpretation and has built several structural framework models using the Petrel software.

Kathe has more than 20 years’ experience in the oil and gas industry, gained while working for major operators and service companies across the Asia Pacific region. These include Schlumberger, Chevron, Woodside and BHP. She has extensive experience in integrated field development and management, focusing on reservoir characterisation, static modelling, in-place volume assessment, uncertainty assessment, field development planning and well planning / execution. Whilst being an expert in static modelling, Kathe has well-developed complimentary skills in petrophysics, geophysics, reservoir engineering and drilling & completions, and has taught both software and theory courses to hundreds of oil and gas professionals across the Asia Pacific area.

Having worked on a wide variety of small and large projects partnering with companies such as Exxon, Shell, BP, Mitsui, Chevron, Woodside and BHP, Kathe also has accomplished stakeholder and project management skills, ensuring positive outcomes and on-time delivery. Kathe has had the opportunity to live and work around the globe during her energy career and enjoys working with colleagues and clients of diverse cultural and personal backgrounds.

Abel Thomas-Hy holds a Bachelor of Petroleum Engineering from the University of Adelaide, Australia. 

Abel joined ERC Equipoise in the Perth office in 2021, after an internship in the Singapore office in 2019. 

As a Reservoir Engineer his role includes resource assessment, production forecasting, dynamic reservoir simulation and field development support. 

During his internship, Abel focused on the coal bed methane resources of Australia. Previous work includes the assessment of EOR potential in heavy oil fields as part of his honours research. 

He is comfortable using Reservoir Engineering tools such as tNavigator, Eclipse, Harmony, GAP and Prosper.
