Successful appraisal wells on Lille Prinsen
Spirit Energy and partners have successfully completed appraisal drilling on the Lille Prinsen discovery on the Utsira High in the Norwegian North Sea. According to the operator the two wells have confirmed a gross resource range of 12–60 million barrels of oil equivalent (mmboe).
The wells in PL167 aimed to verify the hydrocarbon potential in the Lille Prinsen discovery made in 2018. The 16/1-34 A well was seeking to prove reservoir and production properties in the Zechstein group and well 16/1-34 S was targeting an oil leg in the Heimdal formation.
According to the operator, the wells confirmed a gross resource range of 10–50 mmboe in the Lille Prinsen discoveries, and the drill stem test proved very good reservoir properties. A further discovery estimated at 2–10 mmboe was made in the Heimdal formation, also with good reservoir quality.
Cecilie Hiorth, exploration manager in Spirit Energy Norway, said: “The Lille Prinsen appraisals and tests are very positive. The Utsira High area is undoubtedly of great interest to us and the remaining prospectivity in PL167 is significant.
“This has been a good week for Spirit Energy, with news of positive appraisal and test results on both Lille Prinsen and Bergknapp.”
The partnership will now progress development studies to potentially submit a plan for development and operation (PDO) by the end of 2022.
Hiorth said: “We will work closely with our partners to determine the way forward. Also, there is further prospectivity in the surrounding area, which means that new discoveries could be added to a potential Lille Prinsen development.”
The Lille Prinsen discovery is located about 200 kilometres west of Stavanger in production licence 167.
The wells were drilled by the Deepsea Stavanger semi-submersible drilling rig. The PL167 partnership consists of Spirit Energy Norway AS (20%), Lundin Norway AS (40% and operator), Equinor Energy AS (30%) and Aker BP (10%).
