Second Quarter Activities Report
For period ending 30 June 2017
20 July 2017
Key highlights
Costs reduced
Forecast free cash flow breakeven for 2017 reduced to US$33/bbl1, down from US$36.50/bbl in 2016.
2017 production cost guidance reduced to US$8-8.25/boe, down from US$8.45/boe in 2016.
Balance sheet strengthened
Net debt reduced to US$2.9 billion at the end of the quarter, down from US$3.5 billion at the end of 2016.
Production and sales guidance upgraded
2017 production guidance upgraded to 57-60 mmboe and sales guidance upgraded to 75-80 mmboe.
Record PNG LNG performance
PNG LNG operated at an annualised rate of 8.6 mtpa in June, the highest monthly rate since start-up.
Growth in PNG and Northern Australia
PNG: The Muruk drilling programme confirmed the discovery of a potentially significant new gas field.
Northern Australia: Positive results from the two-well Barossa appraisal drilling campaign strengthened the
field’s position as lead candidate to supply backfill gas to Darwin LNG.
Santos Managing Director and Chief Executive Officer Kevin Gallagher said the company’s second quarter results
delivered further progress on reducing costs, lowering net debt and improving the free cash flow position.
“Compared to the end of 2016, our net debt position is US$600 million lower to US$2.9 billion and our forecast free
cash flow breakeven for 2017 now sits at US$33 per barrel1, well below the US$47 per barrel at the beginning of 2016.
“These are strong outcomes that highlight Santos’ ongoing transformation into a low-cost, reliable and high performance
business with a robust asset portfolio that can generate significant free cash flow in a lower oil price environment.”
Second quarter production of 14.7 mmboe was in line with the previous quarter. Sales volumes were up 16% to
21.5 mmboe and sales revenues up 12% to US$769 million primarily due to higher LNG prices and the timing of liftings.
As a result of this solid operational performance, Santos has increased its production and sales volume guidance for
2017 to 57-60 mmboe and 75-80 mmboe respectively.
Mr Gallagher said more efficient, lower cost operations had enabled Santos to increase drilling activity in both the Cooper
Basin and across its GLNG acreage. This has been achieved as a result of the significant improvements in drill, complete
and connect upstream operations unit cost performance over the last 18 months. These additional wells will help boost
production over the next few years so Santos can deliver increased gas supply for the domestic market. Santos also
executed a number of term gas sales into the east coast domestic market during the second quarter.
“As a long-standing supplier of gas to Australian customers in both the east and west coast, we understand the
importance of well-functioning domestic market,” Mr Gallagher said.
“It is also pleasing to see our exploration and appraisal activity growing as part of our disciplined operating model, with
successful outcomes in the Cooper Basin, as well as Muruk in PNG and Barossa offshore Northern Australia.”
1 Free cash flow breakeven is the average annual oil price in 2017 at which cash flows from operating activities (including hedging) equals cash flows from
investing activities. Forecast methodology uses corporate assumptions. Excludes one-off restructuring and redundancy costs and asset divestitures.

Second quarter production was in line with the previous quarter as higher GLNG equity gas and WA domestic gas
production was offset by slightly lower Cooper Basin gas production. First half production was 5% lower than the
previous half primarily due to the sale of the Victorian, Mereenie and Stag assets, partially offset by the ramp-up of
GLNG and higher WA domestic gas production.
Oil price hedging
2.7 million barrels of oil hedging expired in the second quarter under the zero-cost three way collar hedges, resulting
in a positive cash settlement of US$2.2 million being received during the quarter. Oil hedging was also commenced
for 2018. The following oil price hedging positions were in place as at 18 July 2017.

When Brent price is above the weighted average short call price, Santos realises short call price. When Brent price is between the long put price and the
weighted average short call price, Santos realises Brent price. When Brent price is between the long put price and the short put price, Santos realises the
long put price. When Brent price is below the short put price, Santos realises Brent price plus the difference between the long put price and the short put
price.

Sales gas and ethane sales volumes were lower than the previous quarter primarily due to lower spot sales, partially
offset by higher gas sales to GLNG. Condensate and LPG sales volumes were lower than the previous quarter due to
timing of liftings.
Crude oil sales volumes were higher than the previous quarter due to timing of liftings and higher third party volumes.
Sales gas and ethane production was lower as gas capacity additions were offset by natural field decline. Condensate
production was lower due to natural field decline and lower condensate yields.
Higher crude oil production reflected new oil wells coming online offsetting natural field decline.
Fourteen development and appraisal gas wells were drilled during the quarter, taking the total to 25 gas wells for the
first half. Drilling cost and schedule efficiencies continue to be realised and Santos is targeting to drill 52 wells with two
rigs in 2017, compared to 31 wells with the same two rigs in 2015.
Of the nine development gas wells drilled in the second quarter, eight were cased and suspended for future production
and one was drilling at quarter end.
Of the two appraisal and three near-field exploration gas wells drilled in the quarter, three were cased and suspended
for future production.

1 Includes LNG produced from GLNG equity gas, Santos portfolio gas and third-party quantities
Upstream equity sales gas production was 6% higher than the previous quarter and 36% higher than the corresponding
quarter primarily due to production enhancements in Fairview and stronger field performance in Roma. Forty-one
development wells were drilled in the GLNG fields in the second quarter, with a further 18 top holes batch-drilled and
suspended for further deepening as at the end of the quarter. Santos is now targeting to drill approximately 170 GLNG
wells in 2017, up from original guidance of 130-150 wells.
Notwithstanding the higher upstream gas production, sales gas delivered to the LNG plant and LNG production were
both lower than the previous quarter due to the planned four-week statutory inspection shutdown of LNG train 2 in
June combined with the processing of GLNG gas at APLNG during their two-train completion test.
Gross daily production of 490 TJ/day from the Fairview field at the end of the quarter was ahead of forecast. All 12 wells
of the Fairview infield project have been top-set and the project is over 40% complete.
The Roma field continues to de-water and gross daily production of 42 TJ/day at the end of the quarter was in line with
forecast. The Roma 2B project is over 90% complete, with 151 of 159 wells online. The Roma 3A project is 70%
complete, with all 29 wells now drilled and completions underway.
Gross daily production from the Scotia field at the end of the quarter was 28 TJ/d. The Scotia CF1 project is
38% complete, with 33 of the 84 wells spudded. Gross daily production from the Arcadia field at the end of the quarter
was 8 TJ/d.
A planned three-week maintenance shutdown of LNG train 1 commenced in July.

During the quarter, PNG LNG operated at an annualised rate of approximately 8.1 mtpa, lower than the previous quarter
due to scheduled LNG plant compressor maintenance in May, but averaged 8.6 mtpa in June, the highest monthly rate
achieved since start-up.
LNG sales volumes were higher than the previous quarter due to the delivery of three DES cargoes that were shipped
in late March but delivered in the second quarter.

Darwin LNG sales volumes and production were lower than the previous quarter due to planned maintenance.
Condensate sales volumes and production were lower than the previous quarter due to natural field decline and planned
maintenance.
During the quarter, the two-well appraisal drilling campaign in the Barossa field was successfully completed. Positive
results from the campaign, including a successful production test of Barossa-6, strengthened the field’s position as lead
candidate to supply backfill gas to Darwin LNG. The campaign significantly reduced resource uncertainty and further
confirmed the high deliverability potential of the primary Elang reservoir. For further information, refer to ASX release
of 28 June 2017.
Good progress continues to be made with pre-Front End Engineering Design (pre-FEED) studies on the Barossa
development concept. The development concept includes a Floating Production Storage and Offloading (FPSO) facility,
subsea production system and a gas export pipeline, all located in Commonwealth waters. Subsurface data obtained
from the appraisal program will now be integrated into subsurface models to support a FEED-entry decision in early
2018.
The Barossa Area Development Offshore Project Proposal (Barossa OPP) has now also been published by the National
Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) to provide the public with the
opportunity to comment during the project’s early design phase.
The Barossa offshore development area encompasses petroleum retention lease NT/RL5 and potential future phased
development in the smaller Caldita field to the south in retention lease NT/RL6.

Sales gas production in Indonesia and Vietnam was in line with the previous quarter. Stronger oil production in WA in
the quarter (primarily due to cyclone-related shutdowns in the prior quarter) was partially offset by slightly lower oil
production in Vietnam due to well workovers.

Positive production well test results from the Muruk 1ST3 exploration well in the Papua New Guinea Highlands were
announced on 14 June 2017. The Muruk drilling program confirmed the discovery of a potentially significant new gas
field, 21 kilometres northwest of the Hides production facilities. The data from the Muruk drilling program will be
evaluated to assist in the definition of forward appraisal options. Well site preparations are being planned for late 2017
ahead of a potential Muruk appraisal program in 2018.
