  • OML 40 was awarded to SPDC in 1962.
  • The Opuama field was in production from 1975 until 2006 and during that period produced 43.4 mmbbl.
  • In 2006, SPDC undertook a controlled shut down of OML 40.
  • In September 2012 Elcrest Exploration & Production Nigeria Limited purchased a 45% interest in the OML 40 licence.
  • The Opuama field was returned to production in February 2014 with the Opuama-1 well.
  • Further infill wells were completed on Opuama-3 and Opuama-7 in April 2016 and November 2017 respectively.

The reservoirs contain light crudes with API gravities ranging from 47.5° in the shallow reservoirs to 37.8° in the deep and saturated reservoirs. There has been very little pressure depletion over the 30 plus years of production, which indicates a strong aquifer support and consequently leading to very high total ultimate oil recoveries.

Oil can be exported by two routes: (i) via the Shell-operated Trans Escravos Pipeline network running from the Opuama field south along the coastline to the Forcados Oil Terminal, (ii) via shipping to an offshore FPSO.

  • We are currently drilling a workover on Opuama-8 and will follow this up with Opuama-9 and Opuama-10.
