**Tullow Oil plc **(LON:TLW) today announced that the Joe-1 exploration well has
successfully opened a new Upper Tertiary oil play in the Guyana basin.

The Joe-1 exploration well was drilled by the Stena Forth drillship to a Total Depth
of 2,175 metres in water depth of 780 metres. Evaluation of logging and sampling
data has confirmed that Joe-1 has encountered 14 metres of net oil pay in high-quality
oil bearing sandstone reservoirs of Upper Tertiary age. Joe is the first oil discovery
to be made in the Upper Tertiary and de-risks the petroleum system in the west of
the Orinduik block, where a significant number of Tertiary and Cretaceous age prospects
have been identified.

Tullow and its Partners will now evaluate data from the Joe-1 discovery alongside
data from the Jethro-1 discovery announced in August 2019 and await the outcome 
of the Carapa well to determine the optimal follow-on exploration and appraisal 
programme.  

The non-operated Carapa-1 well on the Kanuku licence (Tullow 37.5%) is scheduled
to commence drilling in late September with the Rowan EXL II jack-up rig and will
test the Cretaceous oil play with a result due in the fourth quarter of 2019.

Joe-1 was drilled on the Orinduik licence, offshore Guyana by Tullow’s wholly owned
subsidiary Tullow Guyana B.V.

Tullow Guyana B.V. is the operator of the Orinduik block with a 60% stake. Total
E&P Guyana B.V.  holds 25% with the remaining 15% being held by Eco (Atlantic) Guyana
Inc. On completion of operations, the Stena Forth drill ship will depart Guyana 
and return to Ghana.

> “I am very pleased that we have made back-to-back discoveries in Guyana and successfully
> opened a new, shallower play in the Upper Tertiary age of the Guyana basin with
> our second well. The Joe-1 discovery and its surrounding prospects represent another
> area of significant potential in the Orinduik Block and we are greatly looking
> forward to the next phase of the programme as we continue to unlock the multi-
> billion barrel potential of this acreage.”
