Her clients consistently report enjoying improved relationships in all areas and increased resilience to stress and experience a greater sense of happiness and vitality. Clients gain increased clarity and focus on what they truly want in their lives and experience deeply authentic self-expression. Clients increasingly feel the sense of limitlessness in all aspects of their lives.
One of the tools Susan brings to her work with clients is the Enneagram. She has 30 years of experience utilizing the Enneagram including extensive study under Don Richard Riso and Russ Hudson and a certificate in using the Enneagram in Business under Ginger Lapid Bogda. Under targeted use, this tool has proven time and again to create quick and uncanny awareness of unhelpful habits of mind so as to fast track breakthroughs and achieve desired results much more quickly. Susan uses this tool to break clients out of their habits rather than to reinforce them.
Susan brings a unique combination of business acumen and multifaceted coaching experience to help clients achieve the outcomes and desires they seek.
Diana Hoff co-founded The Unconventional Group (TUG) with Susan Nagl in 2015. Diana serves as the non-executive Chairman for TUG. Diana earned a degree in petroleum engineering from Marietta College (OH), graduating magna cum laude in 1987. She also has completed executive education at Southern Methodist University.
In Denver, Diana was a multiple-term President and 1st and 2nd Vice President of the local chapter of the American Association of Drilling Engineers and was active in the Questar women’s networking group. She is a frequent speaker and panelist for the Women’s Energy Network (WEN), Colorado Oil and Gas Association (COGA) Energy Generation Leadership Program (EnGen) and is a mentor in COGA’s Energy Leadership Collaborative (ELC). The ELC program pairs women graduates from the EnGen program with successful female mentors with a goal of improving the number of women in management and serving on boards throughout the oil and gas industry.
Diana is currently Senior Vice President Operations at Antero Resources, a leading producer in the Marcellus and Utica shale plays of Appalachia. Diana brings more than 30 years of upstream oil and gas engineering and operations experience combined with stakeholder engagement and environmental mitigations implementation. In her current role, she manages an annual budget of up to $1.3 billion, spanning Civil Engineering, Construction, Drilling and Completions, and Production including measurement and analytics. Diana is accountable for the safety performance across these operations.
Diana joined Antero in June 2017 from TUG where she was the Chief Executive Officer. As CEO for TUG, Diana primarily advised non-North American oil and gas companies on unconventional oil and gas planning, execution and development in their home countries. Diana also consulted on team and individual development, succession planning and leadership training.
Prior to TUG, Diana was Vice President Technical, Engineering and Innovation for Santos in Australia from 2010 to 2015, overseeing Drilling & Completions in Australia, Indonesia, Vietnam and Bangladesh as well as corporate-level Major Projects, HSE and Engineering Community Development. In this role, she introduced innovation concepts and drove a culture of innovation at the company.
From 2003 to 2010, Diana led drilling and asset teams in development of the Pinedale Anticline for Questar (now QEP Resources) and also was a key industry player for three years on the ground-breaking Pinedale Supplemental Environmental Impact Statement (SEIS) which was issued in 2008. QEP’s Pinedale development included one of the first liquids gathering systems, up to 50 wells on a pad and early introduction of Tier 2 rig engines and recycling of produced water.
Diana began her career in Production and Drilling with Chevron in the Gulf of Mexico in 1987 and held subsequent progressive operations and engineering roles in Drilling & Completions and Production with Amoco, Basin Exploration, Barrett Resources, and Williams Production.
While in Australia, Diana was appointed to a 5-year term on the Council for the Australian Institute of Marine Science (AIMS) by the Minister of Industry and also served on the AIMS audit committee. She chaired the 2014 SPE Asia Pacific Oil & Gas Conference and Exhibition and was on the Advisory Board for Developing Unconventional Gas (DUG) Australia.
Diana Hoff is an executive in the oil and gas industry. She is a proven leader and motivator with a track record of building teams and driving performance improvement and innovations across multiple companies and project types. She has a Bachelor of Science degree in Petroleum Engineering (magna cum laude) from Marietta College in Ohio. Her unconventional career path began with a grandfather working as an oil and gas “pumper” who often took her to the field with him and a chemical engineer father. Diana’s technical experience has focused on drilling & completions and production in the upstream oil and gas industry. Her rise from foreman and engineer to manager and vice president reflects her values of understanding both the technical work and the challenges that staff today face in completing these tasks.
Diana began her career in the US Gulf of Mexico working offshore projects as a production engineer for Chevron in New Orleans. She embraced the learning challenges, often supervising jobs such as wireline interventions and stimulations herself onsite. Starting in production gave Diana the opportunity to interact with diverse groups across reservoir engineering, geoscience, drilling & completions and joint ventures and built a solid foundation in understanding the interactions between these groups and the needs of each to be effective. Diana then asked for the opportunity to work as a drilling foreman. After three months of training, she was the sole site supervisor of offshore workover rigs in the Gulf. She progressed over the next four years to leading exploration drilling rigs in the Rocky Mountains and working across many basins in the US West for Chevron. In this role, Diana learned how to understand the subtleties of downhole conditions in order to avoid problems and the importance of clear communication and rapport with both field and office staff.
Diana transitioned from working for majors (Chevron and Amoco) to working for independent operators (Basin Exploration, Barrett Resources, Questar/QEP). Much of her work for the independents since the late 1990’s is now called “unconventionals” – coal bed methane, tight sandstone and shale plays. Diana also held production engineering roles focused on production optimization through gas lift, beam pumps, ESP, and plunger lift technology. She was responsible for up to 25 concurrent drilling rigs performing simultaneous operations with completions, construction and production activities as drilling manager, leading well planning and operations, rig contracting and goods & services procurement. Drilling techniques and results were improved each year. As General Manager of the Pinedale Division for QEP, Diana led field development and production optimization while also dedicating considerable time to the planning and implementation of a Supplemental Environmental Impact Statement that resulted in year-round access in an area that had been limited to 3-6 months of operations a year. Diana ensured an integrated approach to subsurface and surface field development planning for 1800 wells to encompass 5 acre downhole well density, multiple-well pad layouts, centralized gathering for gas, water and condensate and compression to support projected production growth. During this period, production from the Pinedale Anticline grew from 280 to 450mmcfd, adding approximately 450 new wells in 4 years.
Diana received the 2009 Denver Business Journal Outstanding Women in Business award. She moved to Australia in 2010 to lead the global drilling and completions operations for Australian producer Santos. In 2011 she was appointed Vice President Technical and Engineering with accountability for corporate EHS, facilities engineering, major projects and production engineering in addition to continuing to lead the drilling and completions teams. The gross operated drilling and completions annual budget was between $1billion and $1.5 billion (AUD) during this period and was delivered within 10% for controllable costs. Diana introduced the principles of unconventional development to executive and technical teams in Australia and led the cultural transition from a conventional development mindset to an unconventional approach. The first significant multi-well pad development in Australia was delivered under her leadership with 30% cost reductions compared to vertical wells. Her team also completed the first commercial shale well in Australia. Diana led EHS functions spanning multiple Australian states, federal and international regimes. She was accountable for ensuring that company standards were aligned with legal and regulatory requirements and reported on company performance to the Board of Directors EHS Committee.
In 2014 Diana became the Vice President Technical, Engineering and Innovation for Santos. In this role, Diana was the recognized innovation leader for Santos at the Executive level, working with technical staff to introduce technical, operational and environmental best practices and new approaches with a particular focus on those from North America. Diana was endorsed by the Australian Minister for Industry and Science to join the Council (Board) of the Australian Institute of Marine Science (AIMS). AIMS is a not-for-profit Commonwealth statutory authority and is Australia’s tropical marine research agency with a mission to generate and transfer knowledge to support the protection and sustainable use of the marine environment, including the Great Barrier Reef, through innovative, world-class scientific and technological research. Diana joined the AIMS Council in 2014 and was named to the Audit Committee in 2015. Diana also served as an Advisory Board member for Hart Energy’s DUG Australia conference from 2013 to 2015. In 2015, Diana founded The Unconventional Group.
Diana has given back to her profession throughout her career. She is a 25 year member of the Society of Petroleum Engineers, held the President and 1st Vice President positions of the American Association of Drilling Engineers multiple times for the Denver chapter, chaired the 2014 SPE Asia Pacific Oil and Gas Conference and Exhibition in Adelaide (holds the record for highest attendance in Australia), and is a member of the Denver SPE golf committee. She has regularly participated in The Unwritten Rules of Engineering seminar for seniors at the Colorado School of Mines. Diana has been a keynote speaker or panelist at numerous events in the US, Canada, Australia, Thailand and Singapore.
