The company said that recent bad weather had delayed preparatory works at the site.
“Over the past month in excess of 780 (millimetres) of rain has fallen in the Puka area, delaying preparatory civil works required for testing operations,” Kea stated.
The company said that recently improved weather conditions had now permitted the necessary access road upgrades to be completed and civil works to commence on site.
Kea expected the Puka-1 well’s initial flow period to start on or around 6 August and take about 30 days.
It said that following the Puka-1 test programme, an appraisal programme including both well and seismic, would be defined and initiated.
Kea reported in April that Puka-1 had hit a 40-metre interval of Mount Messenger reservoir quality sands with a net pay of between 4.5 metres and nine metres.
It also said in June that oil recovered from sampling was excellent quality light oil with a density of 43.7 degrees API and a relatively low pour point of 15 degrees Centigrade.
The company has not altered its original estimate of gross recoverable resources of 1 million barrels of oil and potential upside of up to 3 million barrels of oil.
