Our Clients

Our bespoke analysis and research services are based on understanding the different needs of our clients and providing them with the information and analysis on which to make investment decisions.

For corporate, financial and government clients alike, we support decision-making processes from a commercial and market perspective. Our wide-ranging work includes from commercial due-diligence on mergers & acquisitions, helping oil majors understand the supply chain in a new geographic market, valuing the market for a new technology, and assisting government agencies in developing export business for their energy sectors.


We work extensively with clients throughout the energy supply chain, from multi­national conglomerates to regional SMEs. Much of our work involves assisting our clients in developing an in-depth understanding of new markets.

We are able to leverage a vast wealth of knowledge established through our consulting business, our extensive in-­house data and market models and the professional network we regularly reach out to in our primary research.

“You restored my faith in market research”
Major Manufacturing Group (USA)


We have engaged with engineering firms ranging from niche front-­end engineering and design houses to world­-class EPC companies providing them with corporate strategic advice, acquisition scouting, M&A support, market forecasting and competitive benchmarking.

Our insight into both upstream and downstream oil & gas markets on a highly granular, project-by-project basis, allows for robust and detailed analysis. We use the same approach in the power sector where we are active in the renewable, conventional thermal and nuclear sectors.

Exploration & Production

We provide strategic energy sector insight to IOCs, NOCs and Independent E&P companies and specialise in supply­ chain analysis.

The energy businesses are typically cyclical, and E&P companies face different supply ­chain concerns at each stage of the cycle.

Being able to anticipate supply chain disruption through a combination of supply-­side and demand­ driven analysis allows operators to plan accordingly and avoid unexpected problems in project execution.

Oilfield Equipment Manufacturers

We provide efficient, detailed industry insight through both primary and secondary research by making use of our extensive in-­house knowledge, data and professional networks.

Working with a wide array of OEMs including Cameron, FMC, GE Oil & Gas, NOV, Sulzer and Weir Group across both onshore and offshore sectors, we provide market forecasting & analysis, benchmarking, supply ­chain review, strategic review and acquisition scouting services to leading vendors, tier 2 and tier 3 sub­-suppliers worldwide.


Douglas-­Westwood works extensively with energy sector services companies and our clients include all of the ‘top-10’ OFS providers.

We have a unique and extensive insight into both onshore and offshore field services and have pioneered research into difficult­ to ­access geographies such as Russia and China. We hold the world’s only regularly­ updated land ­rig database and this, combined with our Drilling & Production Outlook, allows us to examine oilfield service markets in every country across the world.


Our business experience ranges from renewable energy to mainstream power generation, where we have worked on all sectors, from clean coal to nuclear.

Since 2000 we’ve also been engaged in every grid-­connected renewable energy sector and have produced independent market forecasts on each. Our coverage of the global nuclear powergen business includes reviews and forecasts of future activity (newbuild and O&M) and country ­specific in­-depth studies for specific technology.


We offer full support through our market and commercial analysis for processes such as initial public offerings (IPOs), refinancing activities, management buy­-outs and mergers and acquisitions.

We also provide sector-­focused commercial due­ diligence (CDD), transaction support and portfolio services to major- and mid-­tier private equity firms, investment banks and debt providers as they work on energy sector investments. We have industry­-leading credentials, including both buy-­side and sell­-side mandates, public to private transactions, refinancing, IPO and project financing, ranging in enterprise value from $5 million to over $1 billion. This spans companies from technology providers, to oilfield services, engineering and equipment companies across the globe.

Industrial Development

Gaining real and enduring benefit from the energy sector, developing local content, job creation and assuring full and fair opportunity for local support and service industries is a challenge for governments worldwide.
