The Securities and Exchange Commission in July alleged Well Advantage had bought shares in energy firm Nexen based on confidential information that China-based Cnooc was about to purchase the company.
Its sales were boosted by existing contracts with major companies such as Nexen and Talisman and new work with Dong Energy and National Grid, among others.
Potential targets include producers in the Canadian oil sands such as Canadian Natural Resources and Nexen, said Peter Churcher, executive vice president of Eagle Energy and a former executive with the Abuu Dhabi National Energy Company.
