Dana reports positive results from North Sea Lille John appraisal well

Offshore staff

STOCKHOLM, Sweden – Dana Petroleum Denmark has proven oil with the latest well on the Lille John discovery in the Danish North Sea, previously drilled by PA Resources (PAR).

The Lille John 2 (LJ2) well was drilled to a total MD of 1,384 m (4540 ft), encountering oil in the same Miocene sandstone reservoir tested by the 2011 LJ1 discovery well, and with improved reservoir thickness and quality.

There then followed a program of coring, logging, and a drillstem test that flowed oil at a stabilized rate of around 500 b/d of oil, with 0.25 MMcf/d of gas and no water. Rates were constrained to avoid the risk of sand production.

Test flow rates were subsequently raised to a maximum of 1,400 b/d, with no sand production experienced. Subsequently, the well was side tracked downdip as LJ2A, confirming similar reservoir development and establishing a 300-m (950-ft) high oil column from LJ1 to LJ2A.

The well will now be P&A’d.

PA Resources CEO Mark McAllister said: “We are pleased with this positive operational result and proof of our conceptual model of improvement in reservoir quality away from PA Resources’ initial play-opening LJ1 discovery. A large suite of data has been gathered which will allow us to thoroughly evaluate the reservoir in detail.

“At this early stage we are encouraged by the reservoir quality demonstrated by the drillstem test although detailed evaluation will be needed to confirm the exact thickness of oil pay penetrated and to assess the recoverable resources in the Lille John accumulation.”
