TGS announces Q4 2015 revenue of approximately 131 MUSD and guides for 2016

ASKER, NORWAY (07 January 2016) - Based on a preliminary review of sales and

investments, TGS provides the following update on Q4 2015:

* Q4 2015 net operating revenues of approximately 131 MUSD, down 56% from Q4

2014

* Expected 2015 full year revenues of approximately 612 MUSD, down 33% from

2014

* Q4 2015 operational multi-client investments of approximately 84 MUSD to

reach full year investments of 497 MUSD

* Cash balance of 162 MUSD at year-end

* Final Q4 2015 results to be reported on 02 February 2016

The weak market conditions are expected to continue in 2016. Consequently, TGS

is planning for a lower activity level, which results in the following guidance

for 2016:

* TGS expects multi-client investments of approximately 220 MUSD

* Multi-client investments are expected to be prefunded 45 to 50%

As announced on 4 December 2015, the accounting practice with respect to

amortization of the multi-client library will change with effect from 1 January

2016. In accordance with the new policy TGS estimates multi-client amortization

of close to 290 MUSD in 2016.  An expected impact of the new accounting practice

will be more predictable and less volatile quarterly normal amortization of the

data library.

"TGS' 2016 operational multi-client investments will be reduced by more than

50% compared to 2015. This is partly a result of lower cost of acquiring seismic

data as average vessel day rates will be substantially lower than in 2015.

Furthermore, the activity level will be reduced as oil companies have become

less willing to prefund new surveys" commented Robert Hobbs, CEO, TGS.  "As a

result of the weak market conditions there is higher uncertainty than usual with

respect to late sales of seismic data. Late sales are normally heavily dependent

on oil companies' E&P spending.  This relationship will continue in 2016 and as

a result, TGS expects late sales to move in line with or slightly better than

general E&P spending trends.  However, the significant reduction in investments

combined with the effect from the cost cutting measures implemented last year

should support positive cash flow development despite the challenging

environment."
