Fugro, AGI to acquire seep
data offshore Canada
Fugro has teamed up with Amplified Geochemical Imaging (AGI) to acquire offshore
hydrocarbon seep data in advance of Canada’s
2018 east coast bid round. Bathymetry, back-
scatter and water column anomaly data will
be collected to pull together a comprehensive
picture of surficial geological features.
The seafloor mapping will be performed by
Fugro using its geophysical vessel, Fugro Dis-
covery, and includes acquisition of 10,500 sq km
( 4,054 sq mi) of multi-beam echo sounder data
and sub-bottom profiler data. This will be followed by coring up to 150 geochemical targets
and 20 heat flow measurements, complete with
shipboard geochemical screening testing, further
shore-based geochemical analyses (carried out
by AGI) and an integrated, interpreted data pack-
age. AGI’s geochemical analyses will determine
the hydrocarbon signature of the samples.
The comprehensive data package will be
available in early 2018 and is being licensed
from both Fugro and AGI.
Offshore Brazil survey
to take in 15th round areas
The BGP Challenger has started a 6,000-
km ( 3,728-mi) multi-client 2D seismic survey
over the Ceara basin offshore northern Brazil,
including areas covered under the country’s
15th licensing round.
According to BGP Marine’s partner Spectrum Geo, the vessel is deploying a 12,000-m
( 39,370-ft) streamer with continuous recording to facilitate extended recording lengths
and high fold data, allowing full interpretation
from Moho to water bottom.
Data will be processed with PSTM, PSDM,
and Broadband products, with first deliveries
expected during 1Q 2018. The 15th round is
due to close during 2Q.
Richie Miller, Spectrum’s EVP Multi-Client
Americas, said: “When the survey is completed it will provide a continuous modern
long-offset, 10-km ( 6.2-mi) grid from the bor-
der with French Guiana to the eastern extent
of the Potiguar basin.”
Fugro details wide-ranging
PEMEX has awarded Fugro and Construc-tora Subacuática Diavaz a $10-million contract
for various operations offshore Mexico. The
program, due to be completed in December,
includes multi-site high-resolution geophysical and geotechnical surveys and laboratory
testing and geoconsulting ser vices to support
design and/or installation of platforms, pipe-
lines, jackup platforms, and deepwater facilities.
Edison receives first package
from East Med 3D survey
Shear water GeoServices has supplied a 3D
fasttrack pre-stack depth migration (PreSDM)
product for Edison International from a new
3D SHarp broadband dataset in the Eastern
Simon Telfer, VP Processing and Imag-
ing at Shearwater, said: “Edison required a
PreSDM volume within weeks of completing
the 3D acquisition. Our Onboard Processing
and Depth Imaging groups worked closely
to draw up a plan. We delivered to Edison a
full 3D pre-stack depth migration product,
including broadband processing and iterative
model-building in just over four weeks from
the final acquired shot record.”
Bruno Garcea, Seismic Supervisor of Edi-
son’s Egypt branch, said: “Depth imaging
and broadband technology are key elements
to achieve a better seismic image of subsalt
plays in the Eastern Mediterranean. So, we
required, for the first time, to obtain a quick
depth volume immediately after acquisition.”
Davide di Biase, Exploration Manager
MENA Area of Edison, added: “Early inter-
pretation, through an accelerated turnaround of
seismic processing, is important factor to better
planning and targeting exploration projects.”
Report shows potential
Energean Oil & Gas has outlined the find-
ings of the first competent persons report
(CPR) for its exploration blocks offshore
Montenegro in the eastern Adriatic Sea.
The report, by Netherland Sewell & Associ-
ates, covers shallow-water blocks 4218-30 and
4219-26, which cover a surface area of 338 sq
km (130 sq mi).
Energean secured 100% operated interests
in the concessions this March, after signing
an agreement with the State of Montenegro.
The CPR estimates total net un-risked prospective recoverable resources (P50) across
the two blocks at 1. 8 tcf of natural gas and
144 MMbbl of liquids (438 MMboe in total).
This is the first component of the first three-
year exploration phase: the mandatory work
program includes a 3D seismic survey over
the two blocks, likely acquired next year, and
geological and geophysical studies.
Energean estimates the total cost of this
initial exploration phase at $5 million.
Offshore Montenegro has been little ex-
plored, despite the fact that oil and gas discoveries were made during drilling by previous
operators in the area in the late 20th century,
although these were not commercialized.
Energean CEO Mathios Rigas claimed the
CPR showed the country may be in the ‘sweet
spot’ of untapped potential in the eastern Adriatic.
“The area remains substantially underex-plored, despite having what appears to be a
working petroleum system with extensive
sandstone and carbonate reservoir develop-
ment. The western offshore Adriatic has been
a prolific hydrocarbon-producing province for
over 50 years for both oil and biogenic gas
and we believe that the same hydrocarbon
plays extend into offshore Montenegro. With
exploration experience in western Greece,
Energean has developed a detailed understand-
ing of the area’s geology and is committed and
uniquely positioned to maximize development
possibilities and unlock the region’s hydrocar-
project sets sail
FairfieldNodal reports that its project to acquire and process high-resolution 3D marine
seismic for the Libra consortium has left port
for deeper waters to begin work. This consor-
tium is led by Petrobras, and includes Total
SA, Royal Dutch Shell Plc, China National
Petroleum Corp., and CNOOC.
The Libra project, FairfieldNodal’s first
such project offshore Brazil, will use the
proprietary Z3000 ocean bottom node sys-
tem. This survey is designed to provide the
operator with the 3D seismic data needed to
make critical decisions on the development
of this field. •

The Fugro Discovery will soon be setting sail
to acquire offshore hydrocarbon seep data in
advance of Canada’s 2018 east coast bid round.
