Canadian company announces gas find in South Sumatra
CALGARY, Canada (Dow Jones): Gulf Indonesia Resources Ltd.
said it and its partners encountered "record gas flow" from the
second test of the Durian Mabok 2 well in South Sumatra,
Indonesia.
In a press release, the company said its partners are Talisman
Energy Inc. and Pertamina.
It said this well tested a 155-metre basal Tertiary limestone
area through three sets of perforations between 2,121 and 2,203
meters and flowed 58 million cubic feet of natural gas a day with
about 370 barrels of condensate a day at 2,900 pounds a square
inch flowing tubing pressure through a one-inch choke. It said
this flow rate was restricted by the capability of the test
equipment.
It said the previous test of the lower section, a 144-meter,
open-hole interval within fractured pre-Tertiary granites above
2,517 meters, was flow-tested through a 60/64-inch choke at a
rate of 26 mmcf/d of natural gas with about 139 b/d of
condensate.
As was the case in the first test, the company said the gas in
the upper section contained low levels of carbon dioxide similar
to the 5.5 percent encountered in the Suban 2 and Suban 3 wells,
"significant in that very little processing will be required to
meet the sales gas specification of 5 percent carbon dioxide."
It said the Durian Mabok 2 wildcat well was drilled on a
previously untested structure eight kilometers from the
successful Suban 3 delineation well announced in March and 7.5 km
from the Suban 2 exploration discovery announced in January.
The company said data from the first test, combined with
seismic mapping, suggest that all three wells have penetrated a
single gas pool which has a minimum gas column of 500 meters and
covers an area of at least 72 square km. The company said the
base of the gas pool hasn't been encountered in any of the three
wells.
Gulf Indonesia said acquisition of a 3D seismic survey over
the field is planned to start in mid-August. Drilling of
additional wells to further delineate the field will follow
seismic interpretations, it said.
The company said the Suban field is about 64 km southwest of
the existing gas and oil infrastructure at the Corridor Project
central gas plant at Grissik and 20 km southwest of the Dayung
field that currently supplies gas to the Corridor Project.
It said gas reserves at Suban will be available to supply
future expansions of the Corridor Project as well as additional
domestic and international gas marketing opportunities.
Gulf Indonesia holds a 54 percent working interest in the
Corridor Block Production Sharing Contract and is contract
operator for Pertamina, the Indonesian state oil company. Gulf
Indonesia is 72 percent-owned by Gulf Canada Resources Ltd.
Talisman has a 36 percent interest and Pertamina has 10 percent.
