Gutes Potenzial im Block 1711

Windhoek - Die Öl- und Gas-Exploration im Block 1711 vor Namibias Nordküste hat erfolgsversprechende Ergebnisse hervorgebracht. Sie müsse nun weitergeführt werden, um genauere Daten zu erhalten. Das sagte Bergbau- und Energieminister Errki Nghimtina gestern im Parlament, wo er über die "vorläufigen Resultate" der Aktivitäten des Joint-Venture-Unternehmens Sintezneftegaz Namibia im Block 1711 referierte (Bericht im Wortlaut siehe unten).

Die geologischen Analysen der Bohrung hätten "Öl- und Gaspotenzial im Block 1711 sowie gute Perspektiven für die Region insgesamt" ergeben, obwohl die Qualität der untersuchten Gebiete "nicht sehr gut" gewesen sei, so der Minister. Dennoch: Laut einer Schätzung von PetroAlliance Service Co. (Moskau) soll sich in einer Schicht zwischen 4698 und 4748 Meter Tiefe ein "potenzielles Gasvorkommen von bis zu 14 Trillionen Kubikfuß" befinden. Das wäre mehr als das Zehnfache des bestätigten Gasvolumens im Hauptfeld des Kudu-Gasfeldes vor der Südküste (ca. 170 km vor Oranjemund), das mit 1,3 Trillionen Kubikfuß (TCF) angegeben wird.

Laut Ministerium wurde bis zu einer Gesamttiefe von 5025 Meter (davon 751 m Wassertiefe) gebohrt, die Explorationsarbeiten wurden im September 2008 abgeschlossen (AZ berichtete). Die Weltwirtschaftskrise habe die Arbeiten verzögert, sagte Nghimtina. Die AZ hat aus vertraulichen Quellen erfahren, dass der russische Energiegigant Sintezneftegaz, der zu 70% an dem Konsortium beteiligt ist, in finanzielle Probleme geraten sei und deshalb nach einem neuen Partner gesucht habe. Zu dem Joint Venture gehören derzeit außerdem Energulf Resources (Kanada, 10%), PetroSA (Südafrika, 10%) Namcor (7%) und die BEE-Firma Kunene Energy (Namibia, 3%).


Ministerial Statement by Honorable Erkki Nghimtina, Minister of Mines and Energy in Respect of Results of Drilling Activities in Block 1711 on 21 July 2009

Honourable Speaker, Honourable Members,

I am honoured and privileged to present to this August House the preliminary results of drilling activities in Block 1711 by a consortium of joint venture partners who have been engaged in hydrocarbon exploration near Kunene mouth.

In March 2006, Block 1711 operators, Sintezneftegaz (70%) Energulf Resources Inc (10%) PetroSA (10%) and Kunene Energy (3%) signed a Petroleum Agreement with the Government of the Republic of Namibia in connection with the exploration of oil and gas in Block 1711. The License Block is located in the northern part of the Namibian continental shelf and is part of Kwanza-Cameroon oil and gas bearing province. In the northern part of the province namely in northern and central basins of Angola (Cabinda, Kwanza) the proven oil and gas bearing reserves capacity are contained in the carbonate sediments of Albian age. The oil fields of Pakassa Formation in the lower Congo basin and Bento Formation in the Kwanza basin were chosen and used as analogues of the Cretaceous carbonate reservoirs. Furthermore additional seismic reinterpretation and reprocessing over the Kunene and Hartman prospects have demonstrated that both these structures can be correlated with the Apto-Albian sediments of the South West African margin.

The operator and the co-ventures applied extreme effort and dedication to the evaluation of oil and gas in the license block. The site for the Kunene-1 exploratory well was determined on the basis of the reprocessed and reinterpreted 2000 km of 2D seismic and 685 square km of 3D seismic data that was originally acquired by Vanco. The well was spudded in April 2008 and drilled to a total depth 5052 meters below mean sea level as per the Agreement with the Namibian Government. The Kunene-1 well is the first ever well to be drilled in Block 1711 over the Kunene prospect of the Namib basin, testing a large 4 way dip structural closure.

The geological analysis of the drilling results, indicate the oil and gas potential of Block 1711 as well as good prospects for the region as a whole. There were gas shows in the Albian and Aptian sediments, confirmed by wire-line logging. It was not possible to fully evaluate the hydrocarbon potential of the penetrated section due to operational problems during testing. The reservoir quality of the tested zones was not was not very good, perhaps due to nearby igneous activity. However, seismic interpretation suggests that alternation of the sediments by the igneous activity may be localized to an area near borehole, and therefore both the tested zones and some untested zones have great potential. PetroAlliance Service Co. of Moscow, a subsidiary of Schlumberger, estimates that the 4,698 m - 4,748 m interval could contain a potential gas resource of up to 14 trillion cubic feet.

All in all, the Government of the Republic of Namibia is happy to announce that Sintezneftegaz Namibia and its co-ventures have met their minimum work commitments to it under this license under often very difficult conditions. The global financial meltdown of last year negatively affected exploration efforts; however it is anticipated, that exploration activities will continue with the view to establish more accurately the quantities and commerciality of the hydrocarbons in Block 1711.

Honourable Speaker, Honourable Members,

In conclusion, I would like to state that this potentiality is high and require more drilling to find more gas and oil.

I thank you.
