block NC115, and partners OMV and Total will proceed with further drilling in the area. Te drilling campaign started in May 2013 and is expected to last until the end of 2015. Te new discovery is the first oil found in Libya by OMV and its partners since the revolution in 2011. OMV has been present in Libya since 1975 and
started production in 1985. In 2012 OMV produced 29,500 barrels of oil equivalent per day (boed) there. Also in Africa, OMV is to invest in an offshore exploration block west of Madagascar. Te company is to acquire a 40 per cent stake in the Grand Prix block from Niko.
Te acquisition is in line with OMV’s ‘profitable
growth’ strategy to develop a balanced exploration and production portfolio and opportunities in the sub-Saharan African region.
Te company says it will farm-in to the area for the planned drilling of an exploration well – and take over as the operator of the block prior to the commencement of drilling currently expected to be early in 2015. Offshore Gabon, Marathon Oil says that the pre-
salt Diaman-1B exploration well has encountered 50-55 metres of hydrocarbon pay in the deep water pre-salt play. Preliminary analysis suggests that the
hydrocarbons are natural gas with condensate content, pending results of ongoing analyses of well data. Te Diaman-1B well was drilled to a depth of 18,323 feet in approximately 5673 feet of water in the Diaba License G4-223. Te Diaman-1B successfully confirms the existence of a working petroleum system and is the
Petrobras confirms two quality oil finds P
etrobras has completed the drilling of another well in the Franco area
(Santos Basin pre-salt). Known as the 3-BRSA-1184-RJS (3-RJS-723), the well is located at a water depth of 2011 metres, 200km from the city of Rio de Janeiro and 7.5km southeast of discovery well 2-ANP-1-RJS (Franco). Te new well has confirmed
the presence of good quality oil in excellent carbonate reservoirs below the salt layer, starting at a depth of 5398 metres.
A total depth of 5900 metres was
reached after a 396 metre column of oil was confirmed. Samples were collected in reservoirs of thickness similar to that of the discovery well, confirming the extension of these oil reservoirs towards the eastern section of the Franco block. Under a right’s transfer agreement,
Petrobras is entitled to produce up to 3058 billion boe in Franco. Te exploratory phase is under way and is expected to be completed by September 2014.
Te company has also completed drilling the fifth exploratory well in the Santos Basin pre-salt Iara area, block BM-S-11. Well 3-RJS-715D (3-BRSA- 1181D-RJS), informally known as Iara Alto Ângulo (‘Iara steep angle’), is located 225km off the Rio de Janeiro coast, at a water depth of 2128 metres. Tis well was drilled in the central
area of the concession’s discovery evaluation plan, 4km to the north of discovery well 1-RJS-656 (1-BRSA- 618). A 310 metre hydrocarbon column was identified. ●
