Lundin Petroleum Successful Appraisal Well and Production Test on Rolvsnes

Lundin Petroleum AB (Lundin Petroleum) is pleased to announce that its wholly owned subsidiary Lundin Norway AS (Lundin Norway) has successfully completed the appraisal well 16/1-28S and production test on the Rolvsnes discovery in the PL338C on the Utsira High in the Norwegian North Sea.

Highlights:

  • Successfully confirmed good productivity from fractured and weathered basement reservoir
    • Constrained production rate of 7,000 barrels of oil per day (bopd)
    • Confirmed connectivity to significant oil volume
       
  • Substantial increase in resources for Rolvsnes
    • Gross resource range increased to between 14 and 78 million barrels of oil equivalent (MMboe) from previously 3 to 16 MMboe
    • Extended well test required to better understand reservoir long term productivity
       
  • De-risks additional on-trend basement prospectivity
    • Goddo prospect exploration well planned for 2019
    • Combined Rolvsnes and Goddo prospective area estimated to contain gross potential resources of more than 250 MMboe

The appraisal well is located approximately 3 km from the Lundin Norway operated Edvard Grieg platform and is the third well on the Rolvsnes oil discovery. The main objective was to confirm commercial rates from a horizontal well drilled in fractured and weathered basement reservoirs, similar to those currently producing in the northern area of the Edvard Grieg field.

The well was drilled horizontally in the reservoir interval and encountered 2,500 metres of fractured and weathered basement. Extensive data acquisition and sampling have been carried out in the reservoir, including a 10 day production test with production logging and bottom hole fluid sampling. A maximum constrained production rate of 7,000 bopd was achieved, while the 5 day main flow period was held at a production rate of 4,200 bopd. The test results show good reservoir productivity and connection to a significant oil volume that benefits from aquifer pressure support, which are positive factors towards demonstrating commercial recovery at Rolvsnes.

Following these positive well results, the gross resource range for the Rolvsnes discovery has been increased to between 14 and 78 MMboe from the previous range of between 3 to 16 MMboe. The long-term production behaviour from this reservoir type needs to be understood better and options are being assessed to conduct an extended well test of the horizontal appraisal well. Rolvsnes is considered a potential tie-back development to Edvard Grieg. The well was drilled by the COSL Innovator semi-submersible drilling rig and following completion of well suspension operations the rig went off hire.

Lundin Norway is the operator of PL338C with a 50 percent working interest. The partners are Lime Petroleum with 30 percent and OMV with 20 percent.

The positive well results at Rolvsnes de-risks the similar on-trend prospectivity on the adjacent PL815 licence where an exploration well is being planned on the Goddo prospect in 2019. The combined Rolvsnes and Goddo prospective area is estimated to contain gross potential resources of more than 250 MMboe.

Lundin Norway is operator of PL815 with a40 percent working interest. The partners are Petoro, Lime Petroleum and Concedo with 20 percent each.

Alex Schneiter, President and CEO of Lundin Petroleum comments:

“I am very pleased to announce the successful completion of the appraisal well and production testing at Rolvsnes. It is not often that a company is able to de-risk a new play concept in a jurisdiction like Norway, and with the results at Rolvsnes, I am encouraged by the significant potential of this weathered and fractured basement play on the Utsira High.

“The key element was to prove commercial production rates and significant connected oil volumes, and I am pleased to note that we have exceeded our expectations on both. We will now focus on understanding the full potential of the play and are planning for an extended well test and further exploration drilling. This result not only validates our organic growth strategy, but also highlights the continued upside in and around our Edvard Grieg facility.”
