Lundin Petroleum completed the first well in its 2014 Malaysian drilling campaign with the successful drilling and testing of Tembakau-2 appraisal well in Block PM307, offshore Malaysia.
Tembakau-2 was drilled by the jackup rig West Prospero to a depth of 1,450 metres in 68 metres 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 3.7 kilometres to the south of the discovery well and penetrated 22 metres of gross gas sands in four sand intervals between 900 metres and 1300 metres 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 64/64” choke and the “I10” sand produced at stabilised flow rate of 15.9 million standard cubic feet per day of gas over a 8 hour period on 72/64” choke.
Each perforated interval was 3 metres. 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, commented; “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 commence development drilling.
Lundin Petroleum holds a 75 percent interest in PM307 through its subsidiary Lundin Malaysia BV. Lundin Malaysia BV’s partner is PETRONAS Carigali Sdn. Bhd. with 25 percent interest. Lundin Malaysia BV operates seven blocks in Malaysia, namely PM307, PM308A, PM308B, PM319, SB303and SB307/308.
