Guyana

Exxon Mobil is underway at exploration well #1-Bulletwood in the Canje Block offshore Guyana. According to the company, Bulletwood is a 500-MMbbl oil prospect of Late Cretaceous Campanian age and is comparable to Exxon Mobil’s Liza Field channel complex in the Stabroek Block. The well will evaluate Upper Cretaceous prospects in the Liza play fairway with some possible deeper reservoir targets. The Canje Block will be the first block offshore to test prospects on the basin floor, which have the potential to contain larger accumulations of recoverable hydrocarbons. Exxon Mobil is the operator and partners include Total, Mid-Atlantic Oil & Gas, and Westwood Energy.

Suriname

Total completed a new oil and gas discovery in offshore Suriname Block 58 at #1-Keskesi East. According to the company, the well hit a 63-m zone of net oil pay with 58 m (net) of black oil, volatile oil and gas pay in Campano-Maastrichtian reservoirs, along with 5 m (net) volatile oil pay in Santonian reservoirs. The well was drilled in approximately 725 m of water, and the rig is drilling ahead to a deeper Neocomian aged targets. Total assumed operatorship of Block 58 and #1-Keskesi East in 2020.

Brazil

Exxon Mobil has scheduled its first offshore Brazil exploration well in almost 10 years. The presalt formation venture will be the #1-Opal wildcat in Block C-M-789 in the Campos Basin. The company also announced plans for a second wildcat at #1-Titan in the Tita presalt Santos Basin, which will be drilled after #1-Opal.

Norway

An oil discovery was announced by ConocoPhillips in offshore Norway PL 891 at wildcat well #6507/5-10 S. The discovery is north of Heidrun Field in the Norwegian North Sea. The well encountered a total oil column of 270 m in Åre and Grey Beds formation, with 90 m of sandstone layers with very good reservoir properties. The preliminary calculation of the size of the discovery is about 4.1 MMbbl to 11.3 MMbbl of recoverable oil equivalent. The objective of the well was to prove petroleum in reservoir rocks from the Early Jurassic Age (Åre) and Triassic Age (Grey Beds). No formation tests were conducted, and additional testing, sampling and assessment are planned. This is the first exploration well in PL 891. The venture was drilled to 2,179 m, and the true vertical depth is 2,214 m. Area water depth is 355 m, and the well will be permanently plugged and abandoned.

Egypt

An oil discovery was reported in Egypt’s Western Deseret by Apex International Energy in the Southeast Meleiha Concession. The #11X-SEMZ hit approximately 65 m of oil pay in the Cretaceous sandstones of Bahariya and Abu Roash G. An initial flow test of Bahariya had a peak rate of 2,100 bbl/d of oil and no water. According to the company, additional uphole pay exists in the Bahariya and Abu Roash G that can be added to the production stream. The venture is about 10 km west of Zarif Field and was drilled to a total depth of 1,759 m. The #11X-SEMZ is the second of a three-well exploration program. The first well, #1-SEMZ, was drilled to about the same depth and flowed 100 bbl/d of oil. The company plans to fracture-stimulate #1-SEMZ at a later date. A third well is planned at #3-SEMZ and is targeting Bahariya.

Turkey

Turkish Petroleum Corp. has reported that the #1-Tuna venture has now been estimated to contain more than 405 Bcm of gas after identifying an additional 85 Bcm of gas. The deepwater exploration well is located in Block AR/TPO/KD/C26-C27-D26-D27 in the Black Sea. It was drilled 2,115 m of water to a total well depth of 4,525 m. It encountered more than 100 m of gas-bearing reservoir in Pliocene and Miocene sands. The company had previously announced that the well data and geophysical studies at #1-Tuna showed a potential of 320 Bcm of lean gas. It is currently the largest discovery in the Black Sea.

7
Oman

Masirah Oil is underway at a second development well, #2-Yumna, in offshore Oman’s Yumna Field in Block 50 in the Arabian Sea. A wildcat venture, #3-Yumna, is also planned in the same block. The original block discovery at #1-Yumna initially flowed more than 8,000 bbl/d of oil. Recently, a mobile offshore production unit was installed in the field along with a 75,000-bbl capacity storage tanker. Masirah Oil is the operator of Block 50 and the Yumna Field with Rex International.
