21 January 2021

Record annual production at top end of upgraded guidance

  • Record annual production of 89 mmboe, 18% above the prior year and at the top end of upgraded guidance provided in December
  • Record quarterly production of 25.4 mmboe, 1% above the prior quarter
  • Record quarterly sales volumes of 31.1 mmboe, 7% above the prior quarter
  • Record annual sales volumes of 107.1 mmboe generated annual sales revenue of US$3.4 billion
  • Fourth quarter sales revenue of US$922 million, up 16%, primarily due to stronger LNG sales volumes (up 23%) and prices (up 25%)
  • Santos' disciplined operating model continues to drive costs lower, with 2020 upstream unit production costs of ~US$8/boe at the lower end of the US$8.00-8.50/boe guidance range

Strong free cash flow and low breakeven oil price

  • Santos generated over US$725 million in free cash flow in 2020 despite lower commodity prices
  • Delivered 2020 free cash flow breakeven oil price of less than US$25 per barrel (before hedging) and less than US$20 per barrel (after hedging)
  • Net debt at the end of the year (including leases) was US$3.7 billion

Growth project milestones achieved

  • Significant milestones were achieved on the Barossa LNG project during the fourth quarter, including execution of a long-term LNG offtake agreement with Mitsubishi for 1.5 mtpa of Santos equity LNG, execution of agreements to transport and process Barossa gas through Darwin LNG, and regulator and joint venture consents for the sell-down of interests in Bayu-Undan and Darwin LNG
  • Moomba CCS project is FID-ready, subject to eligibility for Australian Carbon Credit Units
  • Work continues on the pre-FEED phase for the Dorado project, with FEED entry planned for the first half of 2021 for the Phase 1 oil project. Potential additional liquids tie-backs to be assessed with 2021/22 drilling

Santos Managing Director and Chief Executive Officer Kevin Gallagher said Santos delivered record annual production and sales volumes in 2020, and strong free cash flow of over US$725 million despite lower commodity prices.

"Our consistent and successful strategy combined with the disciplined, low-cost operating model continues to drive strong performance across our diversified asset portfolio and position us for disciplined growth.

"Significant milestones were achieved on the Barossa project during the fourth quarter, including the signing of a binding long-term LNG offtake agreement with Mitsubishi at a price based on JKM and execution of the gas transportation and processing agreements with Darwin LNG. Consents were also received for our sell-downs to SK E&S. Barossa is ontrack for a final investment decision in the first half of 2021.

"2020 saw us ride through the bottom of the cycle while still generating free cash flow and deliver a record 4.3 million tonnes of Santos-equity LNG sales. We remain focused on controlling our costs and living by our disciplined operating model so we are set up to sustain our base business and remain resilient through the cycle even as we see the welcomed strengthening in prices over the past months. Our LNG projects currently have 10 spot cargoes scheduled in Q1.

"We also announced in December an ambitious roadmap to net-zero emissions by 2040, new emissions reduction targets and a commitment to work with our customers to reduce their emissions. Our Moomba carbon capture and storage project is now FID-ready, subject to eligibility for Australian Carbon Credit Units," Mr Gallagher said.

The average realised LNG price was higher than the prior quarter reflecting the linkage of sales contracts to a lagged Japan Customs-cleared Crude (JCC) price. Three-month lagged JCC averaged US$41/bbl in the fourth quarter compared to US$31/bbl in the third quarter. Santos' LNG projects shipped 73 cargoes in the fourth quarter, of which six were spot cargoes (PNG LNG 3, DLNG 2 and GLNG 1). JKM spot prices have increased significantly in early 2021 reflecting strong market demand due to colder weather in North Asia and temporary supply reductions. Santos' LNG projects currently have 10 spot cargoes scheduled in the first quarter of 2021.

Domestic gas production and sales increased in the fourth quarter, reflecting strong contract and spot demand. Santos currently supplies approximately 45% of Western Australia's domestic gas requirements.

Work continues on the pre-FEED phase for the Dorado project, with FEED entry planned for the first half of 2021 and FID in the first half of 2022 for the Phase 1 oil project. Further technical definition across both the FPSO and wellhead platform is being completed with key contractors. Regulatory approvals to support the Offshore Project Proposal and Field Development Plan are also being advanced.

Seismic processing has identified a number of exploration opportunities in close proximity to Dorado. The Pavo and Apus opportunities have been high graded as material tieback development opportunities and are being progressed for drilling in late 2021 / early 2022.

The Ningaloo Vision FPSO (Van Gogh and associated oil fields) is expected back on station from the Singapore shipyard in the first quarter of 2021 as planned with production due to recommence around the end of the quarter. First oil production from the phase two infill drilling project on the Van Gogh field is still expected in late 2021.

Cooper Basin annual production increased by 6% to 16.8 mmboe in 2020, the third consecutive annual rise in production due to consistent application of Santos' disciplined operating model. Fourth quarter gas production was lower than the prior quarter due to planned and unplanned outages and natural field decline.

Fifteen wells were spudded in the fourth quarter, including eight development wells, five appraisal wells and two exploration wells. Eighty-eight wells were drilled in 2020, including 48 development wells, 25 appraisal wells and 15 exploration wells.

The Cooper Basin gas horizontal well pilot program continues to deliver positive results. The wells online to date are achieving on average five times greater initial production rate and forecast reserves outcomes, compared to relevant offset vertical wells, for on average three times cost. During the fourth quarter, one additional horizontal well was drilled (Moomba 257). This well will be brought online in Q1 2021. Further horizontal drilling is planned in 2021 as part of an ongoing horizontal drilling program.

FEED and project assurance are complete for the 1.7 mtpa Moomba carbon capture and storage (CCS) project. Eligibility for Australia Carbon Credit Unit (ACCU) methodology for CCS is the key remaining milestone that would enable an FID decision on the project.

Studies are underway on options to produce and distribute emissions-free hydrogen at Moomba utilising CCS.

Gross GLNG-operated upstream sales gas production increased to 660 TJ/day at the end of the fourth quarter. Consistent production growth from the Roma and Arcadia fields drove the increase, supported by reliable production from the Arcadia and Fairview fields.

The Roma field reached sustained production of over 180 TJ/day driven by growth in Roma East and good legacy field performance. Arcadia also continues to perform well, exceeding 50 TJ/day by year end and recovering strongly from the planned compression plant outage. Scotia field produced a steady 70 TJ/day of production and Fairview was delivering 360 TJ/day at year end in line with expected reservoir decline. Fifty-six wells were spudded and fifty-one connected across the GLNG acreage in the fourth quarter for a total of 302 drilled and 355 connected in 2020.

LNG production of 1.75 million tonnes in the fourth quarter was a record since plant start-up and higher than the prior quarter due to strong customer demand. Full-year LNG sales were in-line with guidance at six million tonnes.

Santos' share of production from the non-operated Combabula and Spring Gully fields was 47 TJ/day, in line with production in the prior quarter.

Following EIS approval by the NSW Independent Planning Commission, the Narrabri Gas Project received Federal approval under the EPBC Act in November 2020. This allows Santos to address EIS and EPBC consent conditions and plan the appraisal drilling program, required to inform the phased development at Narrabri. Workover activities on existing wells progressed through the fourth quarter to optimise gas supply to the Wilga Park Power Station.

Fourth quarter sales and production volumes were 14% and 12% respectively higher than the prior quarter, with two spot cargoes loaded at Darwin LNG. The fourth spot cargo for 2020 was loaded in December and was the largest ever loaded at Darwin LNG, surpassing the previous largest loaded in September 2020. In January 2021, Santos, as operator of the Bayu-Undan and Darwin LNG joint ventures, awarded the sale of a strip of seven 2021 Darwin LNG cargoes at a price based on the Platts Japan Korea Marker (JKM), with one cargo to be delivered each month commencing in February 2021.

Also in January, Santos announced a final investment decision for the US$235 million Phase 3C infill drilling program at the Bayu-Undan field. The program comprises three production wells (two platform and one subsea) and will develop additional natural gas and liquids reserves, extending field life as well as production from the offshore facilities and the Darwin LNG plant.

A final investment decision on the Barossa project to backfill Darwin LNG is targeted for the first half of 2021. Barossa is a world-class LNG project targeting a cash cost of production of approximately US$2.00/mmBtu. Capital expenditure to develop Barossa is estimated at US$3.6 billion gross from FID to first gas, including a leased FPSO with upfront prepayment and option to buy-out. In December 2020, the Processing and Services Agreement, Pipeline Tie-in Agreement and Gas Transportation Agreement were executed by Darwin LNG and the Barossa-Caldita Joint Venture parties, enabling gas produced from the Barossa field to be processed through the Darwin LNG plant. The agreements are subject to a final investment decision on Barossa. Santos has also signed a Letter of Intent to sell a 12.5% interest in Barossa to JERA, subject to FID.

In December 2020, Santos signed a binding long-term LNG Supply and Purchase Agreement (SPA) with Diamond Gas International (DGI), a wholly-owned subsidiary of Mitsubishi Corporation, for the supply of LNG from the Barossa project.

The long-term SPA is for 1.5 million tonnes per annum of Santos equity LNG from Barossa for a period of ten years with extension options, at a price based on JKM. Santos also has options to pursue further LNG transactions through commercial flexibilities negotiated with DGI.

Santos currently has a 68.4% interest and operatorship in Bayu-Undan and Darwin LNG, which will reduce to 43.4% upon completion of a planned 25% sell down to SK E&S. Completion of the SK E&S sell-down is well advanced with consent from Bayu-Undan/DLNG Joint Venture parties and Timor-Leste regulator received. Australian regulatory approvals are also well progressed. The sell-down will complete once the final investment decision on Barossa is taken, which is targeted for the first half of 2021.

Production testing at the Tanumbirini-1 vertical well in the McArthur Basin concluded as planned on 9 October 2020, following successful logging program. Results of the production test significantly exceeded expectations, with an initial peak gas flow rate more than 10 mmscf/d and an average rate of 1.1 mmscf/d during the 19-day test period. The results at Tanumbirini-1 provide critical data to inform the next phase of appraisal, which is expected to include the drilling and multi-stage stimulation of two horizontal wells in 2021.
