PERTAMINA EXPLORATION DISCOVERIES 2003
Amril Adnan
Vice President New Ventures
PT PERTAMINA (PERSERO)
Abstract
During 2003 PERTAMINA drilled 19 exploration wells in Java and Sumatra
wherein 6 wells yields most significant discoveries and 7 wells found
hydrocarbon in lesser level of success. Those important discoveries located
in Randu Blatung of East Java, Pondok Tengah and Karang Baru of West Java,
Tika and Suban Barat of South Sumatra. The significances of those
discoveries may not only determine in term of its value, but also in term of
concepts and impact to continuing exploration.
Randublatung-1/A drilled as a twin for previous blew-up Randublatung-1. The
twin well confirmed a minimum of 150 m gas column in Kujung limestone
reservoir. GWC have not found down to TD in 3112 mMD. The discovered
reservoir characteristics match with model of NE-SW Banyuurip-Randublatung
karstified vugular porosity trend, plus new learning to EW intensive
fracture systems that significantly improve reservoir quality of
Randublatung location. Additional gas reserve plays a role to abiding gas
business in Java.
Pondok Tengah and Karang Baru discoveries are the newest points and also the
best with 205 m netpay in Pondok Tengah in the learning sequence of rift
related play, which cover Baturaja and TalangAkar reservoirs in West Java.
The learning curve has been assembled from informations gained from Tambun,
Wanajaya, Tambun Kelapa, Melandong, and presently Pondok Tengah and Karang
Baru exploratory wells, located at Ciputat and Cipunegara graben systems.
Models of bounding-fault margin, graben-deep, and flexure margin may guide
next exploration in other less explored areas, especially in northern part
West Java.
For area close to central part of West Java, the Sukamulya (as part of
Tunggul Maung Structure) gas discovery may not so significant in reserves
found, but the information is valuable to future oil hunting in area close
to present day Bogor-trough gas kitchen. Small discovery of oil in
unconformity trap (in Tunggul Maung-2) suggesting a model for trapping
mechanism in earliest oil migration into Mio-Pliocene
structural-stratigraphic trap, related to bulge systems in thrust front.
Tika discovery of South Sumatra is one of continuing success stories for the
"go deeper" paradigm. Though play
of Baturaja and Talangakar objective area those of the oldest play in
Sumatra, it still creates a chain of success in area which is overlooks, or
left behind unexplored by imprecise assumptions.
Also the Suban Barat discovery in South Sumatra is a chain of other success
story, wherein related to Baturaja, Talangakar, and basement as objectives.
Concerning basement, since Suban Barat is structurally deeper -down flankly
of nearby proven field of Suban, Suban Barat compel more question for "Do
we have water contact in basement reservoir?" Concerning Baturaja, Suban
Barat has found its thickness of 281 m; the thickest ever penetrated around.
The presentation will share main results and knowledge gained from those
PERTAMINA's Best of Five Discoveries in 2003.

Indonesia -from Sumatra thru Papua, and overseas -i.e. Malaysia, Vietnam and
Iraq. His 25 years of experience covered almost all regions of Indonesia's
exploration objectives; started as Exploration Geologist in Pangkalan
Brandan for Sumatra exploration; Chief Geologist in Cirebon for Java
exploration; Head Section of Regional Evaluation in PERTAMINA Jakarta
Office; Exploration Manager of Eastern Indonesia Region, covering
Kalimantan, Sulawesi and Papua; and then back to Sumatra as Exploration
Manager of this region. In late 90's he intensify his managerial charge as
General Manager for JOB Pertamina-YPF Jambi-Merang Block, before come to
present position as Vice President New Ventures.
Amril Adnan contributes to our scientific community by serving IAGI in many
events and postings along with publishing many papers concerning geology and
exploration subjects. He is currently Chairman of IAGI Jakarta Chapter.
