Papua
New Guinea has five major basins that have good potential
for oil and gas discoveries. These basins are namely,
Bougainville Basin, Cape Vogel Basin, Papuan Basin, New
Ireland Basin, and the North New Guinea Basin. Currently,
most exploration activities are concentrated in the Papuan
basin. However, all these basins have not been fully explored
and still remain prime basins for future oil/gas exploration.
Note that the five major basins in Papua New Guinea are
under-explored, giving good possibilities of discovering
more oil and gas fields in the near future. |

Facilities/Downstream
Engineering |
| |
The
establishment of petroleum production and transportation
facilities has been a great logistical challenge given
the hostile geography of PNG. However, successful breakthroughs
have been achieved by some resident oil companies like
Chevron Niugini Pty Limited and its joint venturers through
the successful development of the Kutubu and Gobe oil
fields. The Petroleum Production Facilities currently
in existence include three plants; Kutubu, Agogo, and
Gobe, with 128,000, 30,000 and 50,000 bbls/day capacity
respectively. |
| |
Approximately
261 km of 20 inch export pipeline extends from the oil
fields in the Highlands to an offshore marine terminal
in the Gulf of Papua. With the existing and the proposed
US$4 billion Gas to Queensland Project infrastructure,
marginal fields within the vicinity of the pipeline route
will become commercially attractive to develop. |
| |
Downstream
processing activity is nil at present with the exception
of Hides Gas Field which processes about 15 MMSCFD of
gas to generate electricity for the nearby Pogera Gold
Mine. Several proposals have been received, expressing
interests in building oil refineries in PNG but none have
been there to be realised. |

Papua
New Guinea Petroleum Production |
| |
Papua
New Guinea's Hydrocarbon production is from four fields:
1) Kutubu Field includes the Agogo field; 2) Gobe Field;
3) Moran field; and 4) Hides gas field. |

Location of Papua New Guinea's oil and gas fields
|
| |
|
| |
Kutubu
|
| |
The
Kutubu oil field was the first field to be developed and
initial production began in October 1991. Cumulative production
achieved from this field is about 246 million barrels
of oil with an estimated total recovery of 300 million
barrels. Reservoir Blocks within the Kutubu Area are : |
| |
a.
Iagifu/Hedinia Main Block Toro
b. Iagifu 3X Block Toro
c. Usano Toro
d. Hedinia 8X Block Toro
e. Hedinia Digimu
f. Agogo Digimu
g. Agogo Toro
|
| |
Forty-six
(46) wells have been drilled to allow production from
these reservoirs. This number of wells includes seven gas
lift wells, three gas injection wells and an average of
25 daily producing wells. |
| |
|
|
|
| |
Gobe
Field |
| |
The
Gobe oil field is separated into two producing fields
Gobe Main and South East Gobe. Initial production began
in 1998 and since then a combined average production of
30,000 barrels of crude oil is achieved. The Gobe main
and South East Gobe wells were produced from the lower
Iagifu and Iagifu reservoirs, respectively. |
| |
|
|
|
| |
Gobe
Main |
| |
A
total of nine wells have been drilled to cater for hydrocarbon
production. This number of wells includes one gas lift
well, one gas injection well, three Plugged and abandoned
wells and four flowing wells. Since production from Gobe
Main field began in March 1998 a cumulative 11.4 million
stock tank barrels (April 2000) has been produced from
an estimated total recovery of 27.5 million stock tank
barrels of oil. |
| |
|
|
|
| |
South
East Gobe |
| |
Eight
wells have been drilled within the South East Gobe field
and these include one gas injection well, 1 Plugged and
abandoned well and six flowing wells. Oil reserves are
estimated to be 56.5 million stock tank barrels of which
a cumulative total of 11.85 million stock tank barrels
(April 2000) has been produced since production began
in April 1998. |
| |
|
|
|
| |
Moran
|
| |
The
Moran oil field is an under-saturated oil field that has
proven estimates of 62.7 million stock tank barrels of
oil in place. A total of ten wells have been drilled to
encounter the productive Toro and Digimu sands although,
at this point in time, only three wells are able to produce
hydrocarbons for further processing. |
| |
Following
the discovery of this field, an Extended Well Test (EWT)
program was conducted as part of the overall appraisal
program. Subsequently, a petroleum development licence
(PDL 5) was granted in February 2001 to the licensees
to undertake full field development. |

|
|
|
| |
Hides
|
| |
Hides
gas field is one of the largest gas reservoirs in PNG.
It supplies gas to power the world class Porgera gold
mine located 70 kilometers northeast of Hides. The Hides
field has an estimated 8 trillion cubic feet of gas reserves
and is currently one of the candidate gas field that will
supply gas to Australia. |
