Expert Witness Profile

GaffneyCline is an international oil and gas consultancy providing technical, commercial, and strategic advice since 1962. From our main offices in Houston, London and Singapore, GaffneyCline’s experts deliver independent upstream, midstream and downstream insights and advice to the energy industry.

GaffneyCline has provided expert witness reports and testimony in support of arbitration (ICSID, ICC, UNCITRAL) and litigation cases around the world. We are fully cognizant of the needs to present highly technical matters in a manner that is clear to tribunals. Our engagements have ranged in size from small disputes to international cases worth many billions of dollars each.

Many oil and gas disputes are based on GaffneyCline’s core expertise in upstream oil and gas reserves and resources analysis, skills that are honed through year-round studies and the preparation of independent reserves reports, accepted by regulatory authorities worldwide. Our experts are engaged through membership of international industry forums, including the Society of Petroleum Engineers’ Oil and Gas Reserves Committee, the group responsible for the global definitions that are used in many legal disputes. We are of course also familiar with the definitions promulgated by the Securities and Exchange Commission in the United States for US cases. Our senior staff provide training in these matters to technical specialists worldwide.

GaffneyCline’s integrated technical teams provide expert opinion and guidance to lawyers and in-house legal teams, often advising on the arguments at an early stage to assist in the direction of the client’s case. Our team includes a number of individuals who are highly experienced in expert work.
