Disclaimer
This presentation may contain forward looking statements that are subject to risk factors associated with the oil and gas businesses. It is believed that the expectations reflected in these statements are reasonable but they may be affected by a variety of variables and changes in underlying assumptions which could cause actual results or trends to differ materially, including but not limited to: price fluctuations, actual demand, currency fluctuations, drilling and production results, reserve estimates, loss of market, industry competition, environmental risks, physical risks, legislative, fiscal and regulatory developments, economic and financial market conditions in various countries and regions, political risks, project delay or advancement, approvals and cost estimates. This presentation may also contain non-IFRS measures that are unaudited but are derived from and reconciled to the audited accounts. All references to dollars, cents or $ in this presentation are to Australian currency, unless otherwise stated. Reserves and Resources. The reserves and resources in this presentation are based on and fairly represent information and supporting documentation prepared by and under the supervision of qualified petroleum reserves and resource evaluators: Dr. Suzanne Hunt, AWE Manager for Engineering and Development, and Mr. Andrew Furniss, AWE General Manager for Exploration and Geoscience. Dr. Hunt, a Petroleum Engineer with a Ph.D. in Geomechanics, is a member of the Society of Petroleum Engineer Engineers and has over 19 years’ experience in the petroleum sector in geoscience, field development planning, reserves estimation, production and facilities engineering. Mr. Furniss, a member of the Society of Petroleum Engineers and the American Association of Petroleum Geologists, holds an MSc in Exploration Geophysics and a BSc (Hons) in Geological Sciences and has over 25 years’ of industry experience in strategic planning, portfolio management, prospect evaluation, technical due diligence and peer review, reserves and resource assessment, the application of advanced geophysical technology and business development. Both have consented in writing to the inclusion of this information in the format and context in which it appears. AWE reserves and contingent resources are estimated in accordance with the following: – SPE/AAPG/WPC/SPEE Petroleum Resources Management System guidelines of November 2011; – SPEE Monograph 3 “Guidelines for the Practical Evaluation of Undeveloped Reserves in Resource Plays”; – ASX Disclosure rules for Oil and Gas Entities, Chapter 5; and – ASX Listing Rules Guidance Note 32. All material changes in reserves and contingent resources are presented to the AWE Reserves Committee. The Committee meets as a minimum every six months, or when any material change occurs, to review and endorse reserves and contingent resource estimates. The endorsed reserves and contingent resources evaluations are reported to the AWE Audit and Governance Committee and form an integral part of the half year and annual financial reporting. AWE applied deterministic methods for reserves and contingent resource estimation for all assets. The reserves were estimated at the lowest aggregation level (reservoir) and aggregated to field, asset, basin and company levels. Estimated contingent resources are un-risked and it is not certain that these resources will be commercially viable to produce. 2
AWE Re-focussed Business
strategy is focused on extracting maximum value from domestic gas assets, where we have exposure to anticipated price increases in both the east and west coast markets over the next two to three years.
