Founder & CEO, ApexCore Consultancy

Cuthbert Thistlewood stands as a prominent figure in the oil and gas industry, leveraging over three decades of expertise as the Founder and CEO of ApexCore Consultancy. His career began on the oil rigs of the Gulf and in the refineries of Aberdeen, experiences that have provided him with a solid foundation for managing global projects with a practical perspective. With a degree in geology from Utah State University and an MBA from the University of Colorado Boulder, Cuthbert has successfully overseen upstream drilling operations valued at over $500 million. He has also pioneered the use of AI-driven compliance tools, achieving an 18% reduction in operational costs, and has established safety protocols that have become standard in major LNG operations across Australia.

Beyond his professional achievements, Cuthbert has a wide array of interests, including a love for music and outdoor pursuits. He enjoys hiking in the canyons of Utah and takes pleasure in culinary traditions, such as perfecting his grandmother's Yorkshire pudding recipe. Known for his engaging demeanor, he often invites colleagues for a round of golf or to engage in thoughtful discussions about literature.

A significant personal experience in 2018 deepened his commitment to empathetic leadership. Cuthbert asserts that "trust is the foundation of every rig, refinery, and relationship." His leadership philosophy is shaped by the values instilled in him by his parents: to work diligently, care genuinely, and strive to improve the environment for future generations. Whether negotiating contracts under challenging circumstances or mentoring the next generation of professionals, Cuthbert is dedicated to cultivating a culture of integrity and collaboration within the industry.

Dr. Carter

Dr. Carter is a geologist known for his unconventional approach, having dedicated 25 years to transforming complex regulatory challenges into strategic advantages. He has designed compliance frameworks for major offshore drilling projects in Singapore and successfully resolved contract disputes exceeding $200 million under UAE energy law, all while integrating cybersecurity measures into upstream operations. His early experience in London's banking sector equipped him with a deep understanding of risk management and return on investment, which he skillfully applies to align health, safety, and environmental (HSE) protocols with the priorities of corporate leadership, from Australia’s Cooper Basin to Norway’s North Sea. Fluent in four languages, Dr. Carter not only navigates the intricacies of geopolitics but actively reshapes them, ensuring the sustainability and success of projects long after agreements are finalized.

“Compliance isn’t a checkbox; it’s the backbone of sustainable growth.”

Mary K Cooper

Mary is the discreet strategist that boards turn to when the stakes are elevated and deadlines are pressing. With a foundation in drilling engineering, she has dedicated two decades to harmonizing strategic decisions made in boardrooms with the practical realities of field operations. Her expertise ranges from optimizing supply chains for major shale operations in Texas to enhancing safety protocols on offshore rigs in Australia. Armed with an MBA in energy finance, she excels at transforming intricate regulations—such as Singapore’s maritime energy codes—into streamlined processes. Additionally, her background in international law has proven invaluable in resolving disputes across diverse locations, from Houston to Jakarta. Rather than pursuing fleeting trends, Mary focuses on constructing robust systems that endure.

“Supply chains aren’t pipelines—they’re lifelines. Treat them that way.”
