Zenith Energy confirms another improvement to Jafarli flow rate

Azerbaijan-focussed oil and gas production company Zenith Energy announced a further update on the production from well C-21 in the Jafarli field on Monday.

The London-listed firm said the most recent production tests carried out recorded a stabilised flow rate from well C-21 averaging approximately 50 barrels of oil per day.

It had announced on 6 October that production from well C-21, which was previously non-producing, had been restored at a rate of 15 bopd.

That followed the successful perforation of 7.1 metres of unexploited pay zones between the depths of 3706-3708.5, 3862-3863, 3865-3867 and 3869.6-3871.2 metres in the Middle Eocene geological structure.

On 10 October, Zenith announced that production had been successfully increased to 35 bopd following the perforation of an additional 7.8 metres of unexploited pay zones between the depths of 3429-3431.8, 3611.5-3615.5 and 3637-3638 metres.

In light of the stabilised flow rate now achieved, the company said its operational team was evaluating the potential benefits of installing an electric submersible pump (ESP).

“I am very pleased with the incremental production increases we have achieved at well C-21 with relatively minimal expense, especially when considering the fact that this well was previously non-producing,” said Mike Palmer, chief operating officer of Zenith’s local wholly-owned subsidiary in Azerbaijan, Zenith Aran.

“We are already assessing a number of other wells across the field where we can replicate the highly successful outcomes accomplished at C-21 and C-26, and, in so doing, successfully work towards achieving our production objective of 1000 bopd by 31 March 2018.

“The use of quad neutron logging technology has certainly been a game changer by giving us exceptional new insight into the significant untapped production potential of our wells.”
