Eland Oil & Gas said its joint venture subsidiary Elcrest Exploration and Production Nigeria Ltd has successfully drilled and completed the Opuama-8 well.
It said the Opuama-8 well had been handed over to the Opuama field production team and the well would flow test into the production facilities and on to export.
It said: 'Under the regulatory guidelines the Opuama production team will conduct a maximum efficient test incrementally testing the well at increasing choke sizes.
'It is expected that, following completion of the MER Test, initial production from Opuama-8 will be in line with previous guidance, at between 5,000 and 7,000bopd (gross).'
Eland said that following the successful completion of Opuama-8 infill well, the OES Teamwork Rig was mobilised to the Opuama-9 drill site and had spudded the Opuama-9 infill well.
It said drilling was expected to be completed in February, with first oil from Opuama-9 of between 4,000 and 6,000bopd (gross) expected in the first quarter of 2018.
