RE: what we are drilling for c373 Apr 2019 09:51
Thanks Zeb,
Thought we should recap the facts as they are in preparation for this work to begin...
Well C-37 Key Facts
- Drilled in 2008 by SOCAR to a total depth of 3,987 meters
- Currently produces at a rate of approximately 5 bopd following the installation of an electrical submersible pump
- Top of Upper Eocene 3,510 meters
- Top of Middle Eocene 3,935 meters
- Top of productive zone 3,925 meters
- An adjacent well, C-22, achieved highly significant production from the Middle Eocene formation
and from the january update...
Well C-37, Jafarli Field
The Company can confirm that preparation activities for well deepening operations in well C-37 of the Jafarli field have been completed successfully. The estimated saving achieved by utilising Zenith's A-80 workover rig to complete these activities has been assessed as approximately US$250,000.
As announced on November 23, 2018, these operations have involved running in hole with a scraper to perform a cleanout of the casing to a depth of 3,904 metres.
During these operations an obstruction was encountered at a depth of 1,830 metres requiring the scraper to be pulled out of hole and further well cleanout operations to be undertaken.
Once further cleanout activities were completed, Zenith's field team ran in hole with a tri-cone drill bit successfully clearing the previously detected obstruction at a depth of 1,830 metres and reaching the target depth of 3,904 metres (production casing shoe). The tri-cone drill bit was subsequently pulled out of hole and a scraper was again run in hole and successfully cleaned out the wellbore to a depth of 3,904 metres as planned.
Following these activities, wireline logging was successfully performed, and the well is now deemed ready for well deepening activities.
