LONDONTullow Oil will participate in three exploration wells offshore Guyana this summer.

The first two will be operated wells on theOrinduik license from June onwards using the drillshipStena Forth.

Initially the vessel will drill the Tertiary Jethro target in around 1,350 m (4,429 ft) of water, followed by the Upper Tertiary Joe prospect in 650 m (2,132 ft) water depth. Both structures could contain 100-200 MMbbl.

Tullow expects the third (non-operated) well, in the Kanuku block, to spud some time during 3Q. This will be drilled by a jackup on the 200-MMbblCarapa prospect in 70 m (229 ft) of water.

Earlier this month, the company won shares in three blocks in the Malvinas West basin underArgentina’s offshore bid round. These comprise 100% of block MLO-122 and 40% of blocks MLO-114 and MLO-119, in partnership with Pluspetrol and Wintershall.

All are in shallow water, Tertiary and Cretaceous age turbidite plays, with low-commitment work programs. Tullow plans to initiate geological studies, 2D reprocessing and 3D acquisition in 2020.

Elsewhere the company is considering drilling opportunities in 2020 and beyond in Mauritania, Côte d’Ivoire, Jamaica, Peru, and Suriname.

Tullow’s production from itsdeepwater fields offshore Ghana was below expectations during 1Q 2019 due to gas compression constraints on Jubilee in February and a delay in completing the Enyenra-10 production well at the TEN field.

Both issues have since been resolved. Gas compression on Jubilee has been reinstated and Enyenra-10 came onstream in early March.

The drillshipsStena Forth and Maersk Venturer worked on drilling and completion operations during the period, with three wells drilled and two completed.

At the end of May, theStena Forth will cease operations in Ghana and will transfer to Guyana in June.
