Proactive Management in an Uncertain Market

Highlights Q3 2015

Revenues of \$225.7 million, compared to \$394.2 million in Q3 2014
EBITDA of \$115.3 million, compared to \$181.7 million in Q3 2014
EBIT, excluding impairments and other charges, of \$9.1 million, compared to \$77.3 million in Q3 2014
Cash flow from operations of \$71.3 million, compared to \$230.7 million in Q3 2014
MultiClient Pre-funding revenues of \$83.8 million with a corresponding pre-funding level of 88%, compared to \$55.4 million and 79% respectively in Q3 2014
Cost reduction program ahead of plan
Total Leverage Ratio requirement for Revolving Credit Facility increased to 4.00:1 through Q1 2017, with no dividend to be paid for 2015
Ramform Explorer and Challenger in process of being cold-stacked and Ramform Viking to be stacked end October
Entered into attractive charter agreements for Sanco Swift and Sanco Sword, leading to cold-stacking of Ramform Vanguard and Ramform Valiant
Agreement to postpone delivery of Ramform Hyperion to Q1 2017
Full year EBITDA expected to be approximately \$500 million

"MultiClient pre-funding revenues for the first three quarters were solid at \$282.4 million, with a corresponding pre-funding level of 121% highlighting the attractiveness of our projects, and the reduced earnings volatility we get from our increased MultiClient focus.

Despite a sequential improvement in the marine contract EBIT margin, we experienced a further market deterioration over the summer, mainly driven by intense competition in preparation for the weaker winter season. Contract revenues and margin through Q4 and Q1 will be adversely impacted.

We have taken further steps to adapt to the current challenging market environment. We have negotiated an amendment to the financial covenants for our Revolving Credit Facility, creating significantly more headroom and preserving our strong liquidity reserve. We continue to cut costs and reduce capital expenditures to optimize cash flow. With the cold-stacking of Ramform Viking and other initiatives taken in Q3, our estimated cost reduction for 2015 is now increased to approximately \$320 million. We have implemented a significant reduction of 2015 CAPEX and further, benefiting 2016 CAPEX, agreed with the shipyard to postpone the delivery of Ramform Hyperion to Q1 2017, subject to approval from the ECA financing banks.

In order to position our fleet for the future and address the industry's vessel oversupply, we have entered into agreements to charter the two vessels Sanco Sword and Sanco Swift, both among the most competitive conventional vessels in the seismic industry."

Jon Erik Reinhardsen, President and Chief Executive Officer

Outlook

The low oil price, reduced oil company spending and intense competition for work among seismic companies impact pricing and utilization negatively. PGS expects market uncertainty and low earnings visibility to continue well into 2016.

Based on the current operational projections and with reference to disclosed risk factors, PGS expects full year 2015 EBITDA to be approximately \$500 million.

MultiClient cash investments are expected to be approximately \$285 million, with a pre-funding level above 100%.

Somewhat above 50% of active 3D capacity is expected to be used for MultiClient in 2015.

Capital expenditures are estimated to be approximately \$175 million, of which approximately \$130 million is for the new builds Ramform Tethys and Ramform Hyperion.

The order book totaled \$245 million at September 30, 2015 (including \$103 million of committed pre-funding on MultiClient projects), compared to \$259 million at June 30, 2015 and \$466 million at September 30, 2014. As of October 19, 2015 approximately 85% of available capacity (which excludes stacked vessels) for Q4 is booked, with corresponding numbers for Q1 2016, Q2 2016 and Q3 2016 being approximately 50%, 55% and 10%, respectively.

Vessel allocation:

		Quarter ended September 30,		Nine months ended September 30,
	2015	2014	2015	2014	December 31, 2014
Contract	35 %	62 %	34 %	49 %	51 %
MultiClient	48 %	21 %	41 %	35 %	31 %
Steaming	8 %	13 %	11 %	11 %	12 %
Yard	1 %	4 %	2 %	5 %	5 %
Stacked/standby	8 %	0 %	12 %	0 %	1 %

Revenues for PGS, or the Company, decreased \$168.5 million, or 43%, compared to Q3 2014. The lower revenues reflect a 68% reduction in contract revenues and a 43% reduction in MultiClient late sales, partially offset by a 51% increase in MultiClient prefunding revenues.

The reduced marine contract revenues in Q3 2015, compared to Q3 2014 were due to less capacity used for contract work, lower average pricing and higher non-chargeable vessel time. The EBIT margin for marine contract acquisition work was approximately break-even in Q3 2015, which is an improvement from Q2 2015, but down from positive 27% in Q3 2014. The weaker marine contract EBIT margin in Q3 2015 compared to Q3 2014 is caused by a generally lower pricing level, standby costs, market driven vessel schedule inefficiencies and permitting delays. The marine contract EBIT margin will fluctuate from quarter to quarter influenced by factors such as vessel scheduling, vessel transits, project specific variables and market conditions.

The increased MultiClient pre-funding revenues in Q3 2015, compared to Q3 2014 were primarily due to more capacity allocated to MultiClient acquisition. Projects in North America contributed the most to pre-funding revenues in Q3 2015, and the increase from Q3 2014.

The reduced MultiClient late sales revenues in Q3 2015, compared to Q3 2014 are a reflection of clients' focus on preserving cash and reducing investments. Europe was the main contributor to MultiClient late sales in the quarter and compared to Q3 2014 MultiClient late sales were weaker in all regions, except Europe.

External imaging revenues for Q3 2015 were down 29% compared to Q3 2014. While Q3 revenues were approximately in line with Q2 2015 revenues, the decrease against the prior period primarily reflects a greater portion of resources allocated to MultiClient projects and a difficult global market environment. Imaging develops and delivers processing solutions that leverage the GeoStreamer advantages to generate unique solutions. All Imaging of the Company's MultiClient surveys is done in-house, and Imaging applies the same technical competency to internal production. Imaging has a pro-active cost focus which enables the Company to balance cost reductions with maintaining capacity and competency.

Note 2 – Net Operating Expenses Excluding Depreciation, Amortization and Impairments

(In millions of US dollars)	Quarter ended September 30,		Nine months ended September 30,	Year ended December 31,
	2015	2014	2015	2014	2014
Cost of sales	95.7	186.2	317.8	458.0	653.6
Research and development costs, gross	7.6	16.7	24.8	42.5	53.9
Capitalized development costs	(3.3)	(5.0)	(9.5)	(11.9)	(16.3)
Selling, general and administrative costs	10.5	14.7	31.6	44.2	59.9
Other charges/(income)	6.5	(0.2)	13.9	(0.5)	(0.7)
Total	116.9	212.4	378.5	532.3	750.4

Reported net operating expenses for the Group (before depreciation, amortization, and impairments) in Q3 2015 were \$102.2 million, or 48%, lower than in Q3 2014, if other charges are excluded. Cost savings initiatives implemented in 2014 combined with an even stronger cost focus this year, a generally stronger USD and continued low fuel prices, contributed to the significantly lower cost base in Q3 2015, compared to Q3 2014. The reported cost of sales also benefitted from more operating cost capitalized as investment to the MultiClient library in Q3 2015, compared to Q3 2014.

The decrease of R&D costs in Q3 2015, compared to Q3 2014 is driven by focus on deploying and finalizing existing projects. The Company's R&D costs are focused on the core business activities of marine seismic acquisition and imaging.

Cost reduction has been a priority for PGS since 2012, when the Profit Improvement Program was introduced. The Company monitors the development of its total cash operating cost base which is the sum of the reported net operating expenses (before depreciation, amortization and impairments) and the cash operating costs capitalized as MultiClient cash investment. The \$150 million savings originally planned for 2015 were increased to \$270 million in the second quarter. In addition to the cold stacking of Ramform Explorer and Ramform Challenger from late September, the Company has decided to cold-stack Ramform Viking around end October. This, combined with other initiatives taken in the third quarter, reduces cost by another \$50 million, to reach a total cost reduction of approximately \$320 million, excluding restructuring cost, when comparing the full year 2015 to the full year 2014.

Fleet adjustment and other cost reductions have led to one off reorganization costs relating to staff reductions and other restructuring activities. The Company incurred \$6.7 million of charges relating to restructuring and severance cost in Q3 2015. The Company expects to incur approximately \$30 million of charges relating to restructuring and severance cost for the full year 2015, of which \$14.5 million were recorded during the first three quarters of 2015 and included in "other charges/(income)" in the profit and loss statement.

Note 3 – Depreciation, Amortization and Impairment

Depreciation, amortization and impairment consists of the following:

	Quarter ended September 30,		Nine months ended September 30,		Year ended
					December 31,
(In millions of US dollars)	2015	2014	2015	2014	2014
Gross depreciation	60.2	71.2	191.0	206.3	278.5
Depreciation capitalized and deferred, net	(32.8)	(20.6)	(87.6)	(81.9)	(97.3)
Amortization of MultiClient library	78.7	53.9	225.8	189.1	344.2
Impairment and loss on sale of assets	65.3	25.0	122.3	34.0	73.8
Total	171.4	129.4	451.5	347.5	599.2

In Q3 2015, gross depreciation decreased as a result of generally reduced capital expenditures and write downs made in Q4 2014. Capitalized depreciation increased in Q3 2015, compared to Q3 2014 as a result of more vessel capacity allocated to MultiClient projects.

Amortization rate of the MultiClient library as a percentage of MultiClient revenues was 65% in Q3 2015, compared to 45% in Q3 2014. The Q3 2015 amortization expense includes a write down relating to certain surveys where sales in the current weak market are lower and more uncertain than previously expected. The amortization level can vary from quarter to quarter depending on the MultiClient sales mix and other factors. For the full year 2015 the Company expects an amortization rate of approximately 60%.

PGS recorded impairments of fixed assets of \$65.3 million in Q3 2015. The impairments relate to seismic vessels and were primarily triggered by the decision to cold stack Ramform Viking in Q4 2015, combined with the planned cold-stacking of Ramform Vanguard and Ramform Valiant in connection with taking over operation of Sanco Swift and Sanco Sword as described in Note 13 Subsequent Events, below.

Before or at the time of taking delivery of Sanco Swift and Sanco Sword, PGS plans to cold-stack Ramform Vanguard and Ramform Valiant and use the equipment on these vessels to equip the two chartered vessels. The seismic equipment from the Ramform Viking will be used as replacement for the rest of the PGS fleet in order to reduce future capital expenditure related to maintenance.

With this change to capacity planning, which involves stacking of all of the three Ramform V-class vessels at least into 2017, the likely timing for return of Ramform Challenger and Ramform Explorer to the 3D market is pushed out in time compared to earlier estimates. Depending on market development and the Company's plans for returning the stacked vessels to 3D operations, estimates for recoverable value could change.

The weak seismic market exposes the Company to impairment of assets and restructuring cost. In 2014 and 2015, the Company recorded impairments of long-term assets and incurred restructuring costs. The Company currently expects a continued weak market into 2016 and a gradual recovery in the years thereafter. Depending on several factors, including market developments and the Company's projections and plans, further impairments of long-term assets, including Property and equipment, MultiClient library, Deferred tax asset and Goodwill, and/or restructuring costs may arise in future periods.

(In millions of US dollars)	2015	2014	2015	2014	2014
Interest expense, gross	(14.5)	(14.8)	(43.2)	(42.2)	(56.8)
Capitalized interest, MultiClient library	5.0	5.3	14.7	14.9	20.3
Capitalized interest, construction in progress	2.6	1.8	6.3	4.7	6.4
Total	(6.9)	(7.7)	(22.2)	(22.6)	(30.1)
Interest expense in Q3 2015 was relatively unchanged compared to Q3 2014. Slightly more interest expense was capitalized to construction in progress in Q3 2015 compared to Q3 2014, due to higher aggregate capital expenditures for the new builds.
Note 5 – Other Financial Expense, Net
Other financial expense, net consists of the following:
	Quarter ended		Nine months ended		Year ended
	September 30,		September 30,		December 31,
(In millions of US dollars)	2015	2014	2015	2014	2014
Interest income	0.6	0.5	1.4	1.4	2.3
Write-off relating to Term loan refinancing	-	-	-	(8.8)	(8.8)
Currency exchange gain (loss)	(10.7)	(7.9)	(15.1)	(7.4)	(13.4)
Other	(1.6)	(1.4)	(5.8)	(5.3)	(6.6)
Total	(11.7)	(8.8)	(19.5)	(20.1)	(26.5)
The higher net other financial expense in Q3 2015, compared to Q3 2014 was mainly due to a significant depreciation of the Brazilian Real against USD and the effect on certain legal deposits in Brazilian Real (see Note 6 - Income Tax Expense). The strong USD against most other currencies, including Norwegian Kroner, has a significant positive impact on the Company's cost base. The Company holds foreign currency positions to manage its operational currency exposure. These positions are marked to
market at each balance sheet date together with receivables and payables in non-US currencies. Foreign currency positions larger than the monetary balance sheet items in the same currency will generally cause a currency exchange loss when the US dollar appreciates.

Note 6 – Income Tax Expense

Income tax expense consists of the following:

		Quarter ended September 30,		Nine months ended September 30,
(In millions of US dollars)	2015	2014	2015	2014	December 31, 2014
Current tax expense	5.4	9.7	19.7	28.0	41.3
Deferred tax expense	24.1	9.2	25.2	3.9	26.3
Total	29.5	18.9	44.9	31.9	67.6

Current tax expense for Q3 2015 of \$5.4 million relates primarily to foreign tax. The high deferred tax expense in the quarter is caused by large foreign exchange movements impacting deferred tax asset positions in Norway and Brazil, as well as a more cautious estimate for recoverability of foreign tax credits.

There is a proposal to reduce the Norwegian corporate income tax rate from 27% to 25% effective from January 1, 2016. While the rate reduction is positive longer term, it will result in a reduction in deferred tax asset of approximately \$4 million which would be recognized as tax expense in Q4 2015, if enacted.

Tax Contingencies

The Company has an ongoing dispute in Brazil related to 5% ISS tax on the sale of MultiClient data from year 2000 and onwards. As of September 30, 2015, the exposure is \$96.0 million, including possible penalties and interest. PGS has made deposits covering \$49.3 million of the total exposure. Due to a significant depreciation of Brazilian Real, both the exposure amount and the value of the deposit has reduced significantly year to date. There has been no significant development of the dispute in the quarter. Because the Company considers it more likely than not that the contingency will be resolved in its favor, no provision has been made for any portion of the exposure.

The Company also has ongoing tax disputes related to charter of vessels into Brazil. The assessments, which seek to levy 15% withholding tax and 10% CIDE (service) tax, amount to \$26 million in total. Because the Company considers it more likely than not that the contingency will be resolved in its favor, no provision has been made for any portion of the exposure.

The Company also has other tax contingencies as described in more detail in the 2014 financial statements.

Note 7 – Property and Equipment

Capital expenditures 1) consists of the following:

	Quarter ended		Nine months ended September 30,		Year ended
	September 30,				December 31,
(In millions of US dollars)	2015	2014	2015	2014	2014
Seismic equipment	9.1	14.3	11.0	87.8	93.8

Other	0.9	2.6	14.0	6.2	11.6
Total	17.0	53.1	121.8	334.4	371.3
1 ) Includes capital expenditure incurred, whether paid or not.

Following cold-stacking of Ramform Challenger and Ramform Explorer late Q3 2015, Ramform Sterling will be upgraded to GeoStreamer using the available streamers. Ramform Viking will be cold-stacked around end October. The remaining available streamers and in-sea equipment from these three vessels will allow the Company to reduce maintenance capital expenditures going forward for the remaining fleet.

PGS has two Ramform Titan-class new builds, Ramform Tethys and Ramform Hyperion, under construction at Mitsubishi Heavy Industries Ltd (MHI) in Japan. Ramform Tethys is scheduled for delivery Q1 2016. PGS has agreed with MHI to move the delivery date of Ramform Hyperion to Q1 2017. The agreement on Ramform Hyperion is subject to final documentation and approval from the ECA financing banks.

The cost of each of the two vessels is approximately \$285.0 million, including commissioning and a comprehensive seismic equipment package, but excluding capitalized interest and post-delivery cost. PGS expect to be able to reduce somewhat the cash portion of this cost by using available equipment from the pool of in-sea equipment.

The agreement with the shipyard provides for payment based on five defined milestones per vessel, with 50% payable at delivery. Seismic equipment is procured by PGS separately from the shipbuilding contract. Accumulated capital expenditures related to the two last Ramform Titan-class new builds as of September 30, 2015 were \$245.0 million.

Note 8 – MultiClient Library

The net book-value of the MultiClient library by year of completion is as follows:

	September 30,	December 31,
(In millions of US dollars)	2015	2014	2014

Completed during 2009	-	8.6	-
Completed during 2010	3.3	15.6	11.3

Completed during 2013	33.5	53.2	46.6
Completed during 2014 (1)	103.0	67.4	117.2
Completed during 2015	178.0	-	-
Completed surveys	358.5	210.9	222.1
Surveys in progress	448.6	558.9	473.1
MultiClient library, net	807.1	769.8	695.2

(1) MultiClient library as of December 31, 2014 with net book value of \$12.7 million was reclassified from "Surveys in progress" to "Completed during 2014" in Q1 2015.

Key figures MultiClient library:

	Quarter ended September 30,		Nine months ended September 30,		Year ended December 31,
2015 (In millions of US dollars)		2014	2015	2014	2014
MultiClient pre-funding revenue	83.8	55.4	282.4	204.4	290.7
MultiClient late sales	36.6	63.9	126.8	189.0	309.0
Cash investment in MultiClient library	95.5	70.4	233.1	286.3	344.2
Prefunding as a percentage of MultiClient cash investment	88 %	79 %	121 %	69 %	84 %
Capitalized interest in MultiClient library	5.0	5.3	14.7	14.9	20.3
Capitalized depreciation (non-cash)	35.4	20.0	90.1	80.8	98.0
Amortization of MultiClient library	78.7	53.9	225.8	189.1	344.2

In Q3 2015, pre-funding revenues corresponded to 88% of capitalized MultiClient cash investment (excluding capitalized interest), compared to 79% in Q3 2014. The pre-funding level in the quarter is driven by good interest for the Company's projects in The North Sea, and North and South America. The sequential decline in pre-funding level is mainly caused by a lower share of customers committing to projects in the processing phase, which fluctuates between quarters. Year to date the prefunding level is 121%, a strong evidence of PGS' attractive MultiClient projects and the Company's determination to maintain a robust pre-funding level over time.

The increased MultiClient cash investment in Q3 2015, compared to Q3 2014 is mainly due to more capacity allocated to MultiClient projects, partially offset by a reduced cost level and less capital intensive surveys.

Note 9 – Liquidity and Financing

In Q3 2015, net cash provided by operating activities was \$71.3 million, compared to \$230.7 million in Q3 2014. The decrease is mainly due to lower earnings and an increase in working capital. Working capital has shown a significant improvement year to date despite some reversal in Q3. In the current market environment some clients are seeking extended payment terms, which may put upward pressure on the working capital going forward. To date the Company has not experienced any significant changes to the average credit days towards customers.

The liquidity reserve as of end Q3 was \$492.3 million and includes cash and cash equivalents and the undrawn part of the revolving credit facility.

Long term debt consists of the following:

Summary of net interest bearing debt:

	September 30,		December 31,
(In millions of US dollars)	2015	2014	2014

Cash and cash equivalents	82.3	90.4	54.7
Restricted cash (current and long-term)	67.7	91.3	92.2
Interest bearing receivables	-	14.0	14.2
Short-term debt and current portion of long-term debt	(24.8)	(24.9)	(24.8)
Long-term debt	(1 172.0)	(1 185.5)	(1 160.1)
Adjustment for deferred loan costs (offset in long-term debt)	(21.7)	(24.9)	(24.1)
Total	(1 068.4)	(1 039.5)	(1 048.0)

The relatively high level of restricted cash relates primarily to deposits made in 2010 and 2011 to initiate law suits with the Rio de Janeiro courts to seek confirmation that sale of MultiClient data in Brazil is not subject to ISS tax (see annual report 2014 for more details). The deposits are denominated in Brazilian Real and the carrying value at end Q3 2015 is approximately \$49.3 million. Restricted cash also includes \$12.7 million held in debt service reserve accounts related to the export credit financing of Ramform Titan and Ramform Atlas.

At September 30, 2015, the Company had approximately 50% of its debt at fixed interest rates. The weighted average cash interest cost of gross debt reflects an interest rate of approximately 4.4%, including credit margins paid on the debt. PGS does not have any major debt maturities before 2018.

The revolving credit facility contains a covenant whereby total leverage ratio (as defined) cannot exceed 2.75:1. At September 30, 2015 the total leverage ratio was 2.03:1.

In October 2015 PGS received consent from the required lenders to its combined Revolving Credit and Term Loan B facility to amend the leverage ratio maintenance covenant and certain other amendments. The maintenance covenant, Total Leverage Ratio (TLR), is changed from maximum 2.75:1 to 4.00:1 for the period up to and including Q1 2017, thereafter tightening by 0.25:1 each quarter down to 2.75:1 by Q2 2018. PGS has agreed a revised margin structure on the Revolving Credit facility. The margin starts at 200 basis points (bps), a 25bps increase from existing margin, as long as TLR is below 2.75:1. If TLR exceeds 2.75:1, it increases stepwise linked to TLR up to a maximum of 325bps. The Company has also agreed that dividend shall not be proposed for 2015 and that for the remaining part of the amendment period dividend can only be paid if TLR is below 2.75:1 for two consecutive quarters and the TLR requirement is reset to 2.75:1 (i.e. as it was before the amendment).

Note 12 – Subsequent Events

PGS has in October 2015 entered into agreements to charter the two vessels Sanco Swift and Sanco Sword from Sanco Shipping AS. PGS considers these vessels to be among the most attractive conventional 3D vessels in the seismic industry, making the PGS fleet even more competitive relative to peers. The vessels are fairly new (delivered in 2013 and 2014) and taking them on longterm time charters would constitute a fleet renewal of the PGS 3D fleet as the first generations of Ramform vessels are approaching 20 years of age. The vessels are expected to be made available to PGS during Q1 2016. The initial charter agreements are for 4.5 and 5.5 years respectively with 3x2 year options for both of the vessels. The terms of the charter agreements are attractive and reflect the current challenging seismic market. The agreements give PGS flexibility for conventional vessel capacity management in the future.

Further, in October 2015 PGS received consent from the required lenders to its combined Revolving Credit and Term Loan B facility to amend the leverage ratio maintenance covenant and certain other amendments. Reference is made to description in Note 9 Liquidity and Financing.

Note 13 – Basis of Presentation

The Company is a Norwegian limited liability company and has prepared its consolidated financial statements in accordance with International Financial Reporting Standards ("IFRS") as adopted by the EU. The consolidated condensed interim financial statements have been prepared in accordance with international Accounting Standards ("IAS") No. 34 "Interim Financial Reporting". The interim financial information has not been subject to audit or review.

The condensed interim consolidated financial statements reflect all adjustments, in the opinion of PGS' management, that are necessary for a fair presentation of the results of operations for all periods presented. Operating results for the interim period are not necessarily indicative of the results that may be expected for any subsequent interim period or year. The condensed interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2014.

The accounting policies adopted in the preparation of the condensed interim consolidated financial statements are consistent with those followed in the preparation of the Company's consolidated financial statements for the year ended December 31, 2014.

EBIT or "operating profit" means Revenues less Total operating expenses. EBITDA, when used by the Company, means EBIT excluding other charges/(income), impairment and loss/gain on sale of long-term assets and depreciation and amortization. EBITDA may not be comparable to other similarly titled measures from other companies. The Company has included EBITDA as a supplemental disclosure because management believes that is provides useful information regarding the Company's ability to service debt and to fund capital expenditures and provides a helpful measure for comparing its operating performance with that of other companies.
