..... dan shelf-edge barrier reef atau knoll reef tipe Kerendan yang
gas-proven. Hanya companies belum ada yang bermain di kedua objektif ini,
mereka masih demam deepwater objective, padahal, belum tentu wilayahnya
ada turbidit sebagus di tegaklurus Delta Mahkam ke timur...
Pak Awang
kalau baca presentasi dari unocal pernah dikatakan bahwa source hc untuk
turbidit adalah debris coal/organic yang dibawa pada saat low stands ....
nah kalau sistem barrier reef source hcnya dari mana ...? apakah dari
endapan marine dari deep waternya atau sama dengan debris yang dibawa
waktu low stand...?

Sayangnya dan kelihatannya (paling tidak saat ini, yaitu saat belum
fully-understood), yang terbaik dari deepwater Mahakam adalah yang tegak
lurus dari Delta Mahakam ke arah timur, baik dari segi depositnya maupun
petroleum charge-nya. Naik ke utara menuju Mangkalihat via
Donggala-Papalang-Podi, atau naik ke selatan menuju Paternoster via
Tanjung Aru, kondisi petroleum system tidak (belum diketahui ?) sebagus di
Gehem-Gada-Gendalo-Ranggas areas. Tapi, makin naik ke utara, atau makin
naik ke selatan, punya objektif yang tidak dipunyai Gehem-Ranggas areas,
yaitu Eocene synrift tipe produktif Tanjung, dan shelf-edge barrier reef
atau knoll reef tipe Kerendan yang gas-proven. Hanya companies belum ada
yang bermain di kedua objektif ini, mereka masih demam deepwater
objective, padahal, belum tentu wilayahnya ada turbidit sebagus di
tegaklurus Delta Mahkam ke timur...

Unocal Sees Success with Gehem-2 Well Offshore Indonesia
Wednesday, February 25, 2004
Unocal said its Unocal Ganal, Ltd. subsidiary has drilled a successful
appraisal well at the Gehem field in the Ganal production sharing-contract
(PSC) area offshore East Kalimantan, Indonesia.
"The Gehem-2 well results show the primary zone of interest to have a
single gas column of greater than 550 feet (168 meters)," said David
Stangor, president of Unocal Indonesia. "This single zone has the
potential to contain up to 1.5 trillion cubic feet of recoverable gas."
A drillstem test (DST) of Gehem-2 flowed at a daily rate of 31.3 million
cubic feet of gas and 1,917 barrels of condensate. The zone was perforated
from 15,362 feet (4,682 meters) to 15,523 feet (4,731 meters) true
vertical depth subsea. The DST had flowing tubing pressure of 6,545 pounds
per square inch on a 32/64-inch choke. The test was constrained by test
equipment capacity. The oil section was not tested.
The Gehem-2 well was drilled 300 feet (91 meters) downdip of Gehem-1 and
encountered 240 feet (73 meters) of net gas pay in zones penetrated by
Gehem-1. Beneath those zones, 55 feet (17 meters) of net oil pay was
discovered in a single zone. Gehem-2 was drilled in 6,036 feet (1,840
meters) of water to a total vertical depth of 17,505 feet (5,335 meters).
The well is located 1.8 miles (2.9 km) south of the Gehem-1 well in the
Ganal PSC.
The next well to be drilled in Unocal's deepwater program offshore
Indonesia is a deep test on the Gula structure, a large anticline
immediately south of Gehem in the Ganal PSC. Following Gula, the company
plans to drill Gehem-3 in the second quarter of 2004 to appraise the
northwestern flank of the Gehem structure.
Unocal Ganal is operator of the Ganal PSC area and holds an 80-percent
working interest. Eni-Ganal, Limited, a subsidiary of Eni, holds the
remaining 20-percent working interest. Unocal said its Unocal Ganal, Ltd.
subsidiary has drilled a successful appraisal well at the Gehem field in
the Ganal production sharing-contract (PSC) area offshore East Kalimantan,
Indonesia.
