Inpex is the operator of the well and only they are authorized to release any information or well results. I don't know what information Staatsolie received about the well results (not a lot IMO) but enough to know that it was a succesfull spud, notice they didn't go as far as to say oil was discovered.

This is good news, if it was a duster all Staatsolie could say is that the well was dry and that would be it, same as when they reported Murphy's results.

Here is the English NR, it's posted on Staatsolie web site, and check the NR about Murphy's dry hole and see how they report a duster.

Exploration Drilling Aitkanti-1 well finished
Teikoku Oil (Suriname) Co., Ltd. (TOS) has finished the exploration drilling in Block 31 in the
offshore area of Suriname on 4 December 2011. TOS believes the purpose of the well was
accomplished and the evaluation is ongoing based on the encouraging and valiant results.
TOS will carry out a comprehensive analysis of the geological findings in 2012. Results from this
analysis will dictate the future exploration plan.
On 14 April 2011, drilling began on the exploration well Aitkanti-1. The drilling took place to a
depth of 5,483 meters, as planned. The drilling process took about 230 days which is longer than
the plan due to technical challenges. As a result of this, the costs have reached about US$100
million which are fully covered by TOS. The Aitkanti-1 was drilled with the jack-up rig Atwood
Beacon.
Teikoku Oil (Suriname) Co., Ltd., is a subsidiary of the Japanese Inpex Corporation, and has been
active since 2007 in Block 31. TOS has a production sharing contract with Staatsolie. Block 31
consists of about 10,407 square kilometers and lies about 70 kilometers from the coast in water
depths varying from 40 to 130 meters.
