We advise on all aspects of oil and gas transactions and projects:

  • mergers and acquisitions/farm-ins/farm-outs/economic interest agreements
  • corporate finance (including private fundraisings, IPOs, secondary fundraisings and dual listings)
  • debt finance including RBLs, project and structured finance
  • joint ventures/joint operating agreements
  • commercial (including joint bidding, production sharing and license arrangements, drilling, well services, seismic data, unitisation and rig agreements)
  • offshore drilling, sub-sea and production
  • pipeline agreements
  • anti-bribery and corruption issues.

Stephenson Harwood also has a leading contentious practice which regularly advises on high-profile disputes in the energy sector, including litigation, arbitration under all major arbitration institutes as well as ad hoc arbitrations, mediations, fraud actions arising out of contractual performance and asset tracing.

In addition, the practice advises in relation to certain highly specialised areas that few international energy practices can replicate such as maritime, LNG and offshore contracting matters. These specialist areas complement our upstream expertise to enable us to provide a full range of legal advice to those operating in the offshore oil and gas sector.
