Tullow outlines 3D seismic survey targets offshore Guyana, Uruguay

Offshore staff

LONDONTullow Oil plans a 3D seismic survey over its Kanuku and Orinduik licenses offshore Guyana.

Orinduik is immediately up-dip of ExxonMobil’s 2015 Liza-1 oil discovery.

In September, Tullow also plans to start a drop core geochemical survey in neighboring Suriname to sample the seabed in offshore blocks 47 and 54, in order to test shallow hydrocarbon indicators.

Analysis of a 3D survey completed during the first half of the year over block 54 has revealed numerous attractive leads and prospects, in particular the Araku prospect, which has amplitudes conforming to a large structure.

In February, Tullow farmed down 35% of block 15 offshore Uruguay to Statoil and received government approval for the transaction late last month.

The partners have agreed to a one-year extension with the government for the block in order to acquire 2,500 sq km (965 sq mi) of new 3D seismic: this activity will start in late 2016.

Subsequent interpretation should to add to the various leads already identified in a 3D survey commissioned by Tullow in 2013. Leads in the under-explored Pelotas basin, in the northeastern part of the block, are thought to be best located for potential oil charge.

Offshore Norway, the semisubmersible has just started drilling the Rome prospect for Tullow in license PL776, with results expected in July.

In addition, the company will participate in next month’s Rovrakula well in PL626, operated by Det norske oljeselskap, and the Cara well in PL636.
