Energy activities for the Northern TerritoryThe Northern Territory Government’s Department of Resources (DoR) Minerals and Energy group (M&E group) administers and promotes responsible development of the Territory’s mineral and energy resources.

The Energy Titles and Operations teams within the M&E group administer a framework for the exploitation of hydrocarbons and geothermal energy in the NT in a manner that aims to maximise the return for all stakeholders, including the community as the owner of all resources in the Territory.

The M&E group administers Energy Titles and Energy Operations in the Territory onshore areas, Territorial waters, and Commonwealth offshore waters.

Territory onshore areaThis consists of over 1.35 million km2 (Area 1 of Figure 1) and contains 19 granted exploration permits, two retention licences and three production licences, where hydrocarbon has been produced since the early 1980s (Figure 2). Oil from the Mereenie field, operated by Magellan Petroleum Australia Ltd, is normally trucked south, whereas gas is piped 1500 km north to Darwin for electricity generation.

Area 1: Onshore Area: 1.35 million km2

Area 2: Territorial Waters: including the new release area three nautical miles around the Northern Territory coastline

Area 3: The Principal Northern Territory Offshore Area: 0.501 million km2 between the Territorial Waters line and the international borders. This area is administered by DoR on behalf of the Commonwealth of Australia.

Area 4: The Territory of Ashmore and Cartier Islands Offshore Area, 77 187 km2 within the Western Australian Offshore Area; this area is administered by DoR on behalf of the Commonwealth of Australia.Area 5: Greater Sunrise is made up of two adjacent but separate gas-condensate fields – Sunrise and Troubadour. The field is jointly administered by the governments of Australia and Timor-Leste.

Area 6: A sixth Joint Petroleum Development Area (JPDA); is administered by a Joint Authority, independent from the Territory Government.

The minimum nominated exploration expenditure work program over onshore titles for the period 2010 – 2014 is A$75.9 million, compared to A$59.2 million for last year.

Territorial WatersTerritorial Waters refers to an area of approximately 15 000 km2 within three nautical miles of the Northern Territory coastline (Area 2 of Figure 1). No applications for exploration were received in 2009. This area is not released for competitive tender like Commonwealth waters, but is available for application at any time.

Principal Northern Territory Offshore Area (Commonwealth waters)The Principal Northern Territory Offshore Area includes over 0.5 million km2 of sea between the three nautical miles line around the Territory coastline and the international borders of Australia (Area 3 of Figure 1). This area is administered by DoR on behalf of the Commonwealth. The Principal Northern Territory Offshore Area comprises 20 exploration permits and three retention leases, and includes World-class gas discoveries. In 2009, two exploration permits were awarded. There is currently no hydrocarbon production in this area (Figure 2).

Aminimumnominatedexpenditureforthefive-yearperiod2010–2014ofA$420millionhasbeencommittedin the Principal Northern Territory Offshore Area. This represents about a 14% decrease compared to the A$480millionthatwascommittedlastyearforthefive-yearperiod2009–2013.

The drilling of 19 wells and the acquisition of 3520 line km of 2D and 1950 km2 of 3D seismic data has been committed for the same period.

Eastern Greater Sunrise Offshore Area (Commonwealth waters)The Eastern Greater Sunrise Offshore Area comprises the NT/RL2 and NT/RL4 retention leases, and was createdin2007toreflecttheintroductionandratificationofanumberofinternationaltreaties.In2007,NT/RL2wasrenewedandNT/RL4wasgrantedforafive-yearterm.

The Territory of Ashmore and Cartier Islands Offshore Area (Commonwealth waters)The Territory of Ashmore and Cartier Islands Offshore Area covers 69 170 km2 towards the northwest of the Western Australian Offshore Area (Area 4 of Figure 1).

The area is a well known, prosperous oil and gas province, comprising 27 exploration permits, six retention leases and eight production licences (Figure 2).

Three Floating Production, Storage and Offtake (FPSO) facilities were actively operating and receiving oil fromfourfullydevelopedoilfieldswithineightproductionlicences,comprisingalloftheTerritory’soffshoreoilproduction (Figure 2). Seven exploration permits and one production licence were awarded in 2009.

A minimum nominated expenditure of A$775 million has been committed for the period 2010–2014. This includes the drilling of 27 wells and the acquisition of 4950 km2 of 2D and 6002 km2 of 3D seismic data.

This represents an 81% increase in expenditure from the A$427.4 million that was committed for the previous period.

Corallina, Jabiru, and Challis (see Figures 7 and 8) continued to produce oil at an expected declining rate, due to natural depletion of the resource and a steadily increasing water cut. A total of 6.6 mmbbl of oil was produced from offshore resources in 2009 (see Table 2). This represented a 15% increase from the 5.7 mmbbl of oil produced in 2008.

• TheNorthernTerritory’stotalonshoreoilproductionwassourcedfromtheMereeniegasandoilfieldnearAlice Springs (Figure 9). A total of 0.236 million barrels of oil was produced from Mereenie in 2009, as compared to 0.3 million barrels in 2008, which is a 21% decrease in onshore oil production.

Blacktip Project

In 2006, Eni Australia signed a Gas Sale Agreement with PowerWater for the supply of gas from the offshore Blacktip Gas Field over a period of 25 years. Up to 860 PJ of gas will be supplied to PowerWater during this period.

2009 saw the completion of the pipeline from the Blacktip Field in the Bonaparte Gulf to an onshore gas treatment plant near Wadeye (NT) and completion of the 286 km-long pipeline from the gas treatment plant to the Amadeus Basin–Darwin pipeline near Ban Ban Springs. Progress on the treatment plant enabled gas to be delivered to the Bonaparte Gas Pipeline in the third quarter of 2009. Full operation was expected to commence in 2010.

Wickham Point Interconnect

This 12 km-long pipeline carries natural gas from the Darwin LNG Plant to the Weddell Power Station and was fully commissioned in August 2009.

Petroleum development, major players and projects in 2009The Major Projects, Asian Relations and Trade Division of the Department of the Chief Minister is responsible for:• facilitating the development of oil and gas resources in the Northern Territory and Timor Sea region• developing the Northern Territory’s long-term relationships in the region• positioning Darwin as Australia’s Asian gateway• promoting key trade relationships• developing the local supply and service industry to support petroleum operations in the region.

INPEX Browse LtdIn September 2008, INPEX Browse Ltd (INPEX) announced that it had selected Darwin as the preferred location for its Ichthys LNG onshore facilities. The Ichthys Project is a joint venture between INPEX Browse Ltd (76%, the Operator) and Total E&P Australia (24%). Gas from the Ichthys Field in the Browse Basin, offshore Western Australia, will be exported to the onshore processing facilities in Darwin via an 850 km subsea pipeline. The World-class Ichthys Project is expected to produce more than 8 million tonnes of LNG, approximately 1.6 million tonnes of LPG per annum and 100 000 barrels of condensate per day.

In January 2009, INPEX awarded the contract for the Front End Engineering and Design (FEED) of its onshoreliquefiednaturalgasplantatBlaydinPointinDarwintotheJKCJointVenture.FEEDistheprojectdevelopmentphase,duringwhichplansfortheproposedLNGprocessingplantaredefined,designedandevaluated in more detail by a contracted engineering company. Development of the Ichthys Project will require capital expenditure ofmore thanUS$20 billion andwill be a significant contributor to theAustralian andregional economies, and to Darwin city.

InApril2009INPEXopenedthecompany’slatestoverseasofficeinDarwin.Also in April, INPEX awarded the FEED contract for its offshore facilities for the development of the

Ichthys Field. The successful contractor was AMEC Engineering Pty Ltd, a wholly owned subsidiary of AMEC plc; one of the World’s leading engineering and project management companies.

Offshore FEED services to be provided by AMEC include engineering for the:• semi-submersible Central Processing Facility (CPF)• FloatingProductionStorage&Offloading(FPSO)unitforcondensatetreatmentandstorage• Umbilicals, Risers and Flowlines (URF)• export pipeline (more than 850 km long) to Darwin.

AMEC is the lead contractor and will be supported by the subcontractors, Aker Solutions and JP Kenny (JPK). Aker Solutions will carry out the CPF and FPSO hull FEED engineering work. JPK will conduct the pipeline and URF FEED engineering work.

A full-time workforce of about 300 people will be required to operate and maintain the onshore facilities over the life of the project. INPEX is working closely with the Northern Territory Government and the Northern Territory Industry Capability Network (NTICN) to ensure local industry participation in the supply of goods and services.

PTTEP Australasia (Ashmore Cartier) Pty LtdIn February 2009, the Coogee Resources Group of companies was purchased by PTTEP Australia Browse Basin Pty Ltd, a wholly owned subsidiary of PTT Exploration and Production Public Company. All of the companies in the group subsequently changed their names, including the titleholder which is now called PTTEP Australasia (Ashmore Cartier) Pty Ltd (PTTEPAA).

PTTEPAA [formerly Coogee Resources (Ashmore Cartier) Pty Ltd] holds titles AC/P32, AC/P34, AC/P40, AC/L1, AC/L2, AC/L3, AC/L7 and AC/L8 in Northern Territory administered waters (Table 3).

PTTEPAA has been one of the major players in the Northern Territory, undertaking a range of petroleum activities that includes production, exploration, drilling and development.

TheMontaraDevelopmentProject isamulti-fieldproject incorporatingfourdifferentoilpools,Montara,Swift, Swallow and Skua, in licence areas AC/L7 and AC/L8.

At Montara, PTTEPAA drilled four (4) new wells (Swift-2, Wisteria-1, Skua-10 and Skua-11), performed two recompletions (Swallow-1 and Swift North-1) and two completions (Skua-10 and Skua-11) to prepare wells for production as part of the Montara Field Development (Figure 11).

Drilling operations

One exploration well was drilled during 2008 as per work commitments. Well location of Octans-1 was finalisedfordrillingtomeetthesecondexplorationwellcommitment.TheOctans-1wellwaslocatedin181mwater depth, 3.4 km west of Libra-1. The well was spudded on 7 June 2009 and drilled to a total depth (TD) of 3933.5 m in the Triassic Challis formation encountering gas in the upper Jurassic–Triassic sands. RCI hydrocarbon samples were recovered to surface, and the well was plugged and abandoned as a hydrocarbon discovery on 6 July 2009.

Seismic operations

There was no seismic acquisition during 2009. Reprocessing of the 2006 Crucis 3D and the 2007 Octantis 3D seismic surveys commenced in September 2009.

The results of the Octans-1 discovery showed that the pre-Callovian unconformity gas play extends southwardsfromtheCruxfield in theChallisFormation,which isstratigraphicallyolder thantheCruxandLibra Plover/Nome reservoirs. However, the quality of the Challis reservoir in Octans-1 is poor to medium, in comparison to the Crux and Libra reservoirs.

energyNT|2009

Wickham Point interconnect pipelineConstruction of a 12 km-long, 12”-diameter 9650 kPa pipeline to transport natural gas from the Darwin LNG Plant to the Weddell Power Station commenced in September 2008 and was completed in August 2009. The pipeline will provide an emergency backup to Darwin’s gas supply through access to gas from ConocoPhillips’ BayuUndanfieldintheTimorSea.

Owen Springs lateral to the Palm Valley pipelineConstruction of a 6 km-long, 8”-diameter, 7000 kPa lateral to the Palm Valley pipeline commenced in the third quarter of 2008 and was completed in February 2009. This pipeline will provide gas to a new power station at Brewer Estate, south of Alice Springs.

EnvironmentTwo incidents (one minor and one major) occurred in the Timor Sea in 2009:1. Approximately 400 litres of diesel was sprayed overboard from the Jabiru Venture FPSO facility when a

Taurushosefailed.Duetothesmallquantityinvolved,thefinenatureofthespray,andthepresenceofrough seas, the diesel was left to degrade quickly and naturally with an extremely small impact on the environment. Inspection of the hose revealed that the armour bindings were severely corroded; this in turn, had compromised the hose’s pressure containment capability, leading to the failure. As a result of thisfinding,otherhosesofthesametypehavebeenreplaced.

2. Light crude oil escaped into the Timor Sea when the H1-ST1 well at the Montara wellhead platform, 690 km west of Darwin, blew out in late August 2009. The blow-out forced the abandonment of the West Atlas drilling rig and required a major containment and cleanup operation of the resultant spill. Due to the quick evacuation actions of the operator, PTTEPAA, there was no loss of life. The spill, although spread over a relatively wide area, appears to have had a minor effect on the environment. This was due to several factors; among them the quick actions by emergency response groups, the quantity of light oil involved, oil quickly dispersing and evaporating naturally, the remoteness of the area from land, and the prevailing weather. Ongoing surveys for environmental damage will continue, although the true extent of the damage, while believed to be not excessive, is unlikely to be known. A Commission of Inquiry into the incident was completed in 2009 and many lessons have been learnt as a result. Actions are now in train to address known areas of concern.
