Canada's Zenith Energy company began C-37 well deepening operations at Azerbaijan's Jafarli oil field on July 26, 2019, Trend reports citing the company, which is the operator for development of Muradkhanli-Jafarli-Zardab oil fields onshore Azerbaijan.
The сompany confirmed that it has successfully retrieved well C-37's entire kill string amounting to approximately 1,000 meters of tubing.
The сompany said it has subsequently begun the process of installing a new API standard 5,000 working pressure tubing spool complete with tubing hanger seat and a new wellhead. Zenith Energy said it has taken this decision in order to mitigate the risks of potential difficulties arising as a result of wellhead failures which had been encountered in previous operations.
"A new BOP system, inclusive of an accumulator unit, choke manifold and remote controls will be subsequently connected as soon as the aforementioned installation is completed. At the same time, the сompany has initiated the preparation of drilling fluids in anticipation for the imminent beginning of drilling activities," said Zenith.
Zenith said no equipment failures have been registered and that all equipment associated with the BD-260 drilling rig has functioned as planned.
In addition, the сompany confirmed that it has received all the necessary approvals from the local authorities for the beginning of drilling activities following a full rig inspection carried out on July 29, 2019.
