Pertamina EP has probably plugged and abandoned Akasia Besar 3 (ASB-3), located in the Jawa Bagian Barat (JBB) PPC, in April 2020, as dry well. ASB-3 was spudded in late August 2019 to appraise the Akasia Besar 1 discovery. The well has a PTD of 2,700m, targeting the volcaniclastics zone of the Jatibarang Formation. Operations for the well were initially planned for approximately 130 days.  IHS Markit understands that the previous appraisal well Akasia Besar 2 (ASB-2) was plugged and abandoned as dry hole in January 2020. ASB-2 was spudded in mid-November 2019, had PTD of 1,900 m and likely targeted the Jatibarang Formation. In December 2019, the operator drilled core section in the attempt to determine the quality of the reservoir.    The previous exploration activity in the Akasia Besar area was a 3D seismic survey acquired in 2016. The survey was designed to cover an area 1,120 sq km, of which approximately 99% was acquired. Elnusa was the contractor for this survey. The seismic data was acquired to improve the definition of reservoir distribution in the area.  ASB-3 is the first appraisal well drilled in the Akasia Besar field which was discovered in 2012. The discovery well Akasia Besar 1 reportedly flowed over 2,200 bo/d and 0.8 MMcfg/d from two DSTs conducted on a carbonate reservoir of the Middle-Upper Miocene Upper Cibulakan Group. It is understood that the first two tests conducted on the Jatibarang Formation did not flow.  The Akasia Besar 1 well was brought onstream through a put on production (POP) scheme in 2013.  Pertamina is operator and sole interest holder in the JBB PPC.  Background Information  Wildcat Akasia Besar 1 was suspended on 28 August 2012 with at least 2,250 b/d of oil and 0.8 MMcf/d of gas flowed during the test. The well had PTD of 2,700 m and was possibly targeting Upper Oligocene to Lower Miocene sandstones of the Talang Akar Formation/Cibulakan Group and Lower Miocene carbonate build-up of the Batu Raja Formation.  Akasia Besar 1 was one of eight exploration wells drilled in the block 2012. Seven of these wells (Bambu Besar 2, Akasia Besar 1, Jati Keling 2, Bambu Gunung 1, Tegal Pacing 2, Jati Besar A and Tambun Deep 1ST1) were concluded as successful while one well (Cikarang 2) was unsuccessful. Aside from the drilling, a 1,012 sq km 3D survey was completed by Elnusa over the block on 25 June 2012. The survey covered the Akasia Bagus structure, wherein a discovery was drilled in early 2010. Data acquisition commenced in early July 2011. Advance party for the survey started in early May 2011.
