Exploration Update: Two Oil Discoveries in Guyana

Two discoveries in Guyana were announced on 16 September 2019, further progressing the exciting story of oil in that country (Hot Spot: Vol. 16, No. 5).

ExxonMobil’s announcement of the success of its Tripletail-1 well added to the previously stated estimated recoverable resource of more than 6 Bboe found in the 26,800 km2 Stabroek Block. The well, drilled in over 2,000m of water, found 33m of high quality, oil-bearing sandstone in the south-eastern end of the block, about 5 km north-east of the Longtail well, which discovered 78m of good sandstone reservoir in June 2018, and close to the 2017 Turbot discovery. It is also approximately 50 km from the first major discovery on the block, Liza, which is in development, with first oil expected by early 2020.

Tripletail is the 14th discovery since 2015 on the Stabroek Block, which ExxonMobil operate with 45% interest, with Hess Guyana Exploration on 30% and CNOOC Petroleum Guyana, 25%.

The second discovery announced on 16 September was on the Tullow-operated Orinduik Block. Joe-1 encountered 14m of net oil pay in high-quality oil-bearing Upper Tertiary sandstone reservoirs, which is the first oil discovery in rocks of that age. The well was drilled in a water depth of 780m and lies about 50 km west of the Liza field and 75m north-northwest of Tripletoe. Tullow has 60% of the block, while Total E&P Guyana holds 25% and Eco (Atlantic) Guyana 15%.

With 14 oil discoveries adding up to an estimated six billion barrels of recoverable oil over the last two years in just one block (Stabroek), offshore Guyana is proving to have quite a promising outlook for hydrocarbon production.

Lebanon. The New Levantine Exploration Opportunity.

Lebanon lies at the centre of known regional hydrocarbon systems, but it is poorly explored and understood, possibly due to topographic challenges to terrestrial geophysical acquisition. A recently acquired suite of airborne geophysical measurements complemented by sub-surface regional resistivity data aims to remedy this situation.
