Operator, consultancy and service company experience Subsurface Key Strengths Independent Operator, consultancy and service company experience Diverse global client base, asset types and terrains Integrated solutions focusing on maximising value Access to other value-adding, value-protecting or compliance assuring services Independent (in terms of client and technology) Staff with operator, consultancy and service company experience (insights into key processes and practices of a diverse client base). Multiple perspectives and focus on value delivery Experience providing services to a diverse, global client base involving a diversity of asset types and terrains - IOC’s, independents, governments, investors and financial institutions (onshore, offshore and deep water assets; oil/gas, clastics, carbonates) Providing integrated solutions that focus on maximising value (internal integration across disciplines – subsurface, wells and surface – and external integration with client teams) Access to other value-adding, value-protecting or compliance assuring services – environmental, safety and risk management.
