Lundin Petroleum has announced a successful initial appraisal campaign offshore Malaysia and the start of drilling on a new exploration well in the Barents Sea.
The Barents well is exploration well 7220/11-1 in PL609 in the Norwegian sector of the Barents Sea. The well will target the Alta prospect, 20km northeast of the Gohta discovery.
The main objective of well 7220/11-1 is to prove the presence of hydrocarbons in sandstones of Triassic age in addition to carbonates of Permo-Carboniferous age. Lundin Petroleum estimates the Alta prospect to have the potential to contain unrisked, gross prospective resources of 261MMboe.
The planned total depth is 2393m below mean sea level and the well will be drilled using the semisubmersible drilling rig Island Innovator. Drilling is expected to take approximately 60 days.
Lundin Norway holds 40% interest in PL609. Partners are RWE Dea Norge and Idemitsu Petroleum Norge with 30% each.
Offshore Malaysia, Lundin completed the first well in its 2014 Malaysian drilling campaign with the successful drilling and testing of Tembakau-2 appraisal well in Block PM307.
Tembakau-2 was drilled by the jackup rig West Prospero to a depth of 1450m in 68m water depth. The well targeted stacked gas reservoirs in Miocene aged sands in a large, low-relief, structure discovered by Lundin Petroleum's Tembakau-1 well in late 2012.
Tembakau-2 is 3.7km to the south of the discovery well and penetrated 22m of gross gas sands in four sand intervals between 900m and 1300m subsea. The main two reservoirs penetrated were fully cored and the well was comprehensively logged.
The reservoir deliverability was measured through production testing. The "I20" sand produced at stabilised flow rate of 15.8 million standard cubic feet per day of gas over a 8 hour period on 64/64in. choke and the "I10" sand produced at stabilised flow rate of 15.9MMscf/d of gas over a 8 hour period on 72/64in, choke.
Each perforated interval was 3m. The gas produced is dry with approximately 0.5% CO2. Multiple samples were obtained for further laboratory analysis. The data gathered will be analysed and integrated with 3D seismic information to update the current gross contingent resource estimate of gas and to provide reservoir information for conceptual development studies.
Ashley Heppenstall, President and CEO, said: "The appraisal drilling results from Tembakau are positive. We are incorporating the results of the well into an updated resource estimate. We will now move forward in reviewing conceptual development options and I am hopeful that this will lead to another commercial development project in Malaysia."
The well has been plugged and abandoned and the West Prospero rig has moved to the Bertam oil field well head platform location, also in PM307, to start development drilling.
Lundin Petroleum holds a 75% interest in PM307 through its subsidiary Lundin Malaysia. Lundin Malaysia BV's partner is PETRONAS Carigali Sdn. Bhd. with 25% interest. Lundin Malaysia operates seven blocks in Malaysia; PM307, PM308A, PM308B, PM319, SB303, and SB307/308.
