Gaffney, Cline & Associates     

Impartial, confidential, technical, commercial and strategic advice

50 years of excellence in energy industry consulting – Upstream, Midstream and Downstream
Gaffney, Cline & Associates (GCA) provides both broad-based and detailed technical, commercial and strategic advice to clients across the upstream, midstream and downstream sectors of the oil and gas industry, using a project team approach.

GCA’s People - Unparalleled experience, enthusiasm, diversity, integrity and reputation
GCA’s personnel bring extensive experience in the petroleum industry gained from numerous projects around the world to every project. Their diverse backgrounds include employment with international and national oil companies and major consulting firms. This diversity of expertise has strengthened our capability and reputation to provide consistent, high quality, impartial, technically sound and commercially astute advice—a reputation we intend to maintain with every project undertaken. 

Full range of disciplines - Experienced experts - Multi-disciplined approach

GCA possesses all the capabilities found in an integrated oil company. Project teams work closely together to derive solutions designed to meet the technical, commercial and strategic requirements specific to each assignment. As such, the awareness of our staff with regards to their related disciplines is often much greater than in a conventional technical consultancy or operator.

A global presence and established reputation

With offices in North and South America, the United Kingdom, Russia, Kazakhstan, Singapore and Australia, GCA has completed or is currently engaged in oil and gas projects located in all the petroleum regions of the world. We are an industry leader with an established reputation across oil and gas companies, governments and National Oil Companies, as well as leading financial and legal institutions.

Exceptional insight delivered in practical terminology
GCA's projects are typically complex analyses of high-value technical, commercial and strategic issues. Communicating the results of the work requires a comprehensive understanding of the needs and concerns of the client and the ultimate beneficiary. GCA explains how the results and conclusions are derived, and doesn’t simply tabulate unjustified output. This becomes especially important when the results are to be read by those with limited background knowledge of the subject matter, for example: public offerings, litigation, and arbitration proceedings. GCA understands these needs and delivers accordingly—and that is what makes us unique.

Technical, strategic and commercial consulting and expertise

GCA provides both broad-based and detailed technical, strategic and commercial advice to clients across the upstream, midstream and downstream sectors of the oil and gas industry. Our professionals encompass all the capabilities found in an integrated oil company, and combine years of experience providing technical analysis and interpretation on assets from hundreds of petroleum basins around the world.

Drawing on an extensive knowledge-base of lessons learned, GCA experts apply a multi-disciplined taskforce approach to assess and recommend optimal solutions designed to meet the technical, strategic and commercial requirements of a project’s objectives.

Our experts remain cognizant of new developments, trends and issues impacting the global energy industry to provide robust and impartial advice to today's decision makers.

GCA, the energy to help you succeed.

GCA personnel have considerable experience, on behalf of both private and state companies, in valuing properties, negotiating, creating options, analyzing proposals, drafting agreements and closing transactions with potential partners.

GCA experts adopt a truly integrated and holistic approach to all commercially oriented advisory projects. The resulting evaluations are robust, impartial and reasoned to better help optimize the selection of commercialization options.

Within the gas sector, GCA can analyze the feasibility of selling into local markets versus commercialization as compressed gas or liquified natural gas (LNG). Frequently, we look at other gas monetization options, such as gas to liquids (GTL), petrochemicals or fertilizers.

Active in all sectors of the oil and gas industry, GCA can test the economic performance of your upstream, midstream or downstream projects under various scenarios to provide an informed, documented recommendation.
