Research Services

Each year, the EI Knowledge Service handles over 13,000 queries that range from very specific questions, which may be answered immediately, to those which require extensive research on a particular subject. Amongst our services, we can offer:

  • Quick queries answered free (up to 5 minutes). For example address and telephone numbers; petrol pump prices; simple statistics; etc.
  • Extended desk research for example for detailed information on companies; statistics; oil industry operations; etc. See our FAQs section for details of our fees and charges
  • Project-based research opportunities to partner with the EI to undertake or facilitate specific work items such as our Collections.
  • Survey and questionnaires to gauge opinion of and engage with EI members. The Energy Barometer initiative includes a survey of professional members and a resulting report published annually.

Another great reason to visit the library is to see our amazing painted ceiling dating from 1777, complete with chariot and mythical beasts...
