As
of 1.1.2002 about 1.3 million line-km of 3D seismic and
642,000 line-km of 2D seismic has been acquired in Malaysia.
A total of 956 exploration wells have been drilled from
1962 to 2001. Since the inception of the latest R/C PSC
arrangement in 1997, there is a marked increase in exploration
drilling and seismic activities. In 2002 Petronas is planning
to drill 47 exploration wildcat and appraisal wells and
shoot a total of 187,000 line km of both 2D and 3D seismic. |

There
are currently 44 producing oil fields and 11 producing
gas fields and several others are under development. These
oil and gas fields produce about 600,000 barrels of oil
and 5.5 billion cubic feet of gas per day respectively.
The
nation's oil and gas reserves stood at 3.4 billion barrels
and 82.5 trillion cubic feet respectively as of 1 January
2001. |

Oil
and gas are currently being produced from all three regions;
Peninsular Malaysia, Sarawak and Sabah. Sedimentary deposition
and subsequent structural overprints in these regions
have resulted in a variety of structural and stratigraphic
configurations which provide conducive conditions for
hydrocarbon generation, migration and entrapment. |

Peninsular
Malaysia Region |
| |
|
| |
There
are currently 10 offshore blocks under exploration PSCs
or have exploration commitments. Oil and gas production
from Peninsular Malaysia account for approximately 63%
and 44% of the country's total production respectively.
The region covers mainly offshore areas of Peninsular
Malaysia and is contained in four main sedimentary basins,
namely the Malay Basin and the Penyu Basin to the east,
and the North Sumatra Basin and the Central Sumatra Basin
in the Melaka Straits to the west. Current exploration
targets are clastic reservoirs of Miocene and Oligocene
age. |

Sabah
Region
|
| |
|
| |
There
are currently seven offshore blocks under exploration
PSCs or have exploration commitments. Oil and gas productions
from Sabah account for approximately 14% and 5% of the
country's total production respectively. The Sabah Region
covers a wide area of offshore and onshore blocks contained
in three main sedimentary basins, namely the Sabah Basin,
the N.E. Sabah Basin and the S.E. Sabah Basin. Current
exploration targets are clastics and carbonates reservoirs
of Miocene and Pliocene age. |

Sarawak
Region
|
| |
|
| |
In
Sarawak, there are currently 10 offshore blocks held under
exploration PSCs or have exploration commitments, including
one deepwater block. Oil and gas productions from Sarawak
account for approximately 23% and 52% of the country's
total production respectively. The Sarawak Basin covers
a wide area both onshore and offshore the State of Sarawak
that has been divided into several geological provinces,
namely the West Baram Delta, Balingian, Central Luconia,
Tinjar, Tatau, West Luconia and SW Luconia and SW Sarawak
Provinces. Each one of these provinces is unique in terms
of hydrocarbon playtypes. |
