well update - GUYANA

5 August 2022 - Tullow Oil plc (Tullow) announces that drilling operations at the Beebei-Potaro exploration well, drilled in the Kanuku licence, offshore Guyana, have been completed. The well encountered good quality reservoir in the primary and secondary targets but both targets were water-bearing.

The Noble Regina Allen rig drilled the Beebei-Potaro well to a Total Depth of 4325 metres in 71 metres of water and the well has been plugged and abandoned. Tullow will integrate the well results into its regional subsurface models and work with its joint venture partners before deciding on next steps.

Repsol is the operator of the Kanuku licence with a 37.5% working interest. Tullow holds 37.5% with TOQAP holding 25%.
