QGC LNG Field at Tara Water Monitoring and Management Plan

1.0 Stage 2 CSG water monitoring and management plan

1.0 Stage 2 CSG water monitoring and management plan

1.1 INTRODuCTION

Coal seam gas has been produced in Queensland for more than 10 years and accounts for about 80% of all gas

consumed in the State. QGC is expanding its existing CSG operations through development of the Queensland

Curtis LNG Project (the QCLNG Project).

The QCLNG Project is developing coal seam gas in the Surat Basin in southern Queensland to supply gas to

export and domestic markets (refer Figure 1). QGC, a wholly-owned subsidiary of the BG Group, is drawing on its

own extensive CSG expertise as well as the wider group's international liquefied natural gas (LNG) experience to

develop the world's first unconventional LNG facility.

The process of extracting coal seam gas from the Walloon Coal Measures (WCM) deep underground produces

water which, when treated, can be beneficially used by local farmers, industry and communities.

Central to the project's success is ensuring that the integrity of the Great Artesian Basin (GAB), of which the Surat

Basin is a part, is maintained. To this end, QGC has made a firm commitment to geological and hydrogeological

data gathering, analysis, modelling and monitoring and the establishment of environmentally sustainable water

management strategies around CSG operations.

This Stage 2 WMMP outlines QGC's approach and commitment to water monitoring and management for the

QCLNG Project. It is based on existing and new scientific information and approach.

The Stage 2 WMMP:

Highlights those tasks completed and started since project approval (October 2010)

Summarises key findings from data collected and interpreted to date

Sets out a schedule of tasks, delivery mechanisms and target completion dates (i.e. a plan) for SEWPAC to

assess compliance against relevant approval conditions.

1.1.1 GOALS AND OBjECTIVES

QCLNG's success rests fundamentally on maintaining the long-term integrity of the GAB, ensuring minimal

impact on the sustainability of local and regional ground and surface water resources and mitigating impacts

on ecological systems considered to be MNES at springs associated with GAB strata. To achieve these objectives,

QGC's strategy is:

Developing robust water management tools

Establishing an extensive monitoring network

Calculation of early warning signals and response actions

Quantifying and managing potential risks and developing response strategies

Implementation of responsible CSG water management and beneficial use options.

Throughout this document, reference is made to results generated by QGCs GEN2 groundwater model. However,

the Queensland Water Commission's (QWC) Underground Water Impact Review (UWIR) is due for formal release

in October 2012 and will include an updated groundwater model which addresses cumulative impacts. Upon

formal release of the UWIR and finalisation of associated legal arrangements regarding access to model results,

QGC will update the predictions contained in this Stage 2 Water Monitoring and Management Plan.

1.2 QCLNG SNAPShOT

The QCLNG Gas Field Approval (EPBC 2008/4398) authorises the project area which includes the following

petroleum tenures:

Authority to Prospect (ATP): 574, 610, 621, 632 (portion of), 647, 648, 651, 676 and 768 (portion of)

Petroleum Lease (PL): 179, 201, 228, 229, 171,180, 211, 247

Petroleum Lease Application (PLA): 212, 257, 259, 261, 262, 263, 273, 274, 275, 276, 277, 278, 279.

The application, granting and conversion of petroleum lease applications is an ongoing process with the

Queensland Department of Natural resources and Mines (DNRM).

The list below represents all changes that have occurred with QGC tenures within the overall approved QCLNG

Gas Field Approval (EPBC 2008/4398) to the 17 September 2012

ATPs converted to PLs and thereby no longer exist: ATP 610 (covered by PL 247), ATP 651 (covered by PLs 276

and 277)

PLAs granted to PL: 212, 257, 263, 273, 274, 275, 276, 277, 278, 279, 398, 442, 466, 474

PLAs withdrawn: 259 (covered by grant of PL 273)

PLAs applied for over ATP areas held by QGC (PLA): 392 and 393 (portion of ATP 574), 398 and 399 (portion of

ATP 768), 443, 458, 459, 461 and 472 (portion of ATP 676) 442, 466 and 474 (portion of ATP 648)

Petroleum Facility Licence Applications (PFL): PFL 19, PFL 22

Petroleum Facility Licence Grants (PFL): PFL 19, PFL 22.

The QCLNG gas fields project area is shown at Figure 1.

The approval conditions allow for the development of up to a maximum of 6,000 production wells and impacts

related to gas field development over a 50-year period to 31 October 2060. It should be noted that approximately

2,000 wells will be in production at any one time, with new wells progressively brought on-line to replace

maturing wells, which will be decommissioned.

The gas fields component of the project covers 468,000 ha within the Walloon Fairway of the Surat Basin. Project

activity is located on land between the towns of Taroom, Wandoan, Condamine, Tara, Chinchilla and Dalby.

4

Works will be carried out as a single stage of development and comprises:

Up to 6,000 gas production wells with around 2,000 wells scheduled by mid-2014. The balance of wells will be

phased in to replace declining wells over the life of the project

Installation of wells and associated well pad surface equipment including wellhead separators, wellhead

pumps, wellhead flares, telemetry devices and metering stations

Installation of gas gathering systems (High Density Polyethylene (HDPE) and steel pipes)

Completion of field compressor stations and central processing plants, including dehydration facilities,

substations and power lines

Development of access tracks, borrow pits, warehouses, construction and operations camps, offices and

telecommunications

Construction of water gathering lines, trunklines, ponds, treatment facilities and brine storage ponds

Preparation of the necessary infrastructure for the beneficial use of treated CSG water

Installation of above-ground 132 kv power lines to connect the new central processing plants to third party

substations. Also, installation of underground and above-ground 33 kv power lines connecting central

processing plant substations to field compressor stations and Water Treatment Plant substations

Development of accommodation camps for construction and operations people, along with warehouses, lay

down areas, communication towers and fibre optic cabling.

QGC will develop the acreage outlined in Figure 1 with most blocks contributing to QCLNG production in 2014.

Therefore, QGC has developed an holistic water monitoring and management plan for the entire project life to

responsibly monitor and manage CSG water for the whole acreage. For all key activities a base plan has been

selected and each base plan is described in the Stage 2 WMMP. If alternative strategies with better outcomes are

proven over time, QGC will apply for revision of the plan.

This Stage 2 WMMP covers the first stage of major gas field development and will be revised and updated no

later than the commissioning of the LNG Plant, expected to be December 2013.

1.3 ADDRESSING REGuLATORY REQuIREmENTS

QCLNG gas field development was referred to the Federal Minister for the Environment under EPBC referral

2008/4398. The Minister approved the action on 22 October 2010, subject to certain conditions, including the

submission of this Stage 2 WMMP by 23 April 2012. The implementation of the approved Stage 2 WMMP must

not be later than 22 December 2012.

5

6QGC will develop about 6,000 CSG wells. QGC works with landholders, traditional custodians of the land and environmental scientists before final decisions on site selection are made.
