The offshore Taranaki Maari oil field has started flowing a week after
production was halted following two minor oil spills at the floating
production, storage and offtake vessel Raroa. Operator OMV said
that field production had restarted on 27/11/2010, following
confirmation that the oil sheen seen on November 20th was due
to a small amount of residual oil trapped beneath the Raroaís hull. It
said production was shut down on November 20th as a
precautionary measure and that a thorough review, including divers
examining parts of the vesselís hull, was subsequently undertaken in
consultation with government regulatory authority Maritime New Zealand.
OMV said it was now known that the residual oil noticed on November 20th
was the result of an earlier incident, on October 18th, when
oil was noticed on the water near Raroa during de-ballasting operations.
OMV said divers had now cleaned the affected area of the Raroa and
production had resumed. (Source:
Spar 2 well in WA-4-R in the Carnarvon Basin has flowed gas at a rate of 58 million cubic feet per day, confirming the potential of the Spar field. Associated condensate production of 16 barrels per MMcf of gas was also recorded from the 55 metres of net gas pay in the primary target Upper Barrow reservoir. Santos said with the larger than estimated gas pay at Spar 2, the recoverable resource in the field is expected to be greater than the 335 petajoules it had previously estimated. Spar 2 had also intersected about 40 metres of net gas pay over several sands within the deeper B Reticulatum zone. A drill stem test over a 12 metre section flowed 5MMcfd as well as condensate production of 6bbl per MMcf of gas. Spar 2 is expected to be tied back to Varanus Island through the Halyard development. Earlier this year, Apache and Santos confirmed plans to develop the Halyard field in WA-13-L in the Carnarvon Basin as a domestic gas project for Western Australia. Halyard is expected to be online in mid-2011 at an initial rate of 50 terajoules per day. (Source: PetroleumNews, 25/11/2010).
Woodside Petroleum has had some welcome news for its Pluto liquefied natural gas project expansion with a new gas discovery in WA-404-P of the Carnarvon Basin. The Remy 1 well intersected 33 metres and 39 metres of gross gas over two separate zones within the Triassic target with wireline logging being carried out to obtain pressure and gas samples. Remy 1 was drilled to a depth of 4,555 metres with the Ocean America semi-submersible and successfully appraised the Martell gas discovery 500 metres away. (Source: PetroleumNews, 26/11/2010).
The petrophysical assessment of wireline logs from the Backreef 1 well by Oil Basins and Weatherford found the zone between 915-965 metres within the Yellow Drum equivalent/Gumhole formations has a possible reservoir interval of around 48.9 metres with possible net pay of 39.2 metres. The assessment also found the Lower Laurel formation from 894-910 metres is predominantly a tight limestone and likely to be the effective seal for the hydrocarbon trap delineated by Backreef 1. The company is now planning to specifically target the new oil play for rapid production assessment late in the second quarter of next year by either drilling low-cost shallow exploration wells or re-entering and stimulating Backreef 1.
