Impartial, confidential, technical, commercial and strategic advice
50 years of excellence in energy industry consulting
Gaffney, Cline & Associates (GCA) is a global oil and gas consultancy that has been offering technical, commercial, and strategic advice to the oil and gas industry for more than 50 years. GCA was established in 1962 by two far-sighted oil industry insiders, Peter Gaffney and Ben Cline. These two pioneers could see that the petroleum industry needed energy consultants with broad skills and extensive experience to solve complex technical and business problems across the entire petroleum investment lifecycle.
Unparalleled integration of technical, strategic and commercial insight
GCA is particularly recognized as one of the leading providers of Reserves and Resources assessments, which are required for many purposes including statutory market reporting, stock exchange listing, development planning, project finance and asset valuation.
