TGS in partnership with Electromagnetic
Geoservices ASA have agreed to jointly invest in a 3D electromagnetic multi-client
survey covering 11 blocks, or approximately
3,300 sq km ( 1,274 sq mi), in the Hoop area
of the Barents Sea.
The 3D EM data is being acquired by the
M/V Atlantic Guardian. Data will be available
to clients through both EMGS and TGS.
Under terms of a previously announced
agreement, EMGS will have access to TGS’
2D seismic data for survey planning and
integration purposes, while TGS will obtain
access to 3D EM data to evaluate and plan
subsequent multi-client work over the area.
Eni and Rosneft started seismic operations in the Fedynsky and Central Barents
license areas, in the ice-free part of the
Russian sector of the Barents Sea. The 2D
seismic survey is planned to cover 9,950 km
( 6,183 mi) over the two license areas.
The seismic survey, preceded by environmental and fshery studies, is in compliance
with Russian legal environmental requirements and license agreements. During the
seismic survey a program of environmental
monitoring will be implemented.
Eni and Rosneft formed joint venture companies to operate each of the Russian offshore projects, with Rosneft holding 66.67%
and Eni holding the remaining 33.33%.
.of general interest, and 25 wells provided by early participants in the study. All wells
will be conditioned top-to-bottom for geophysical purposes using RSI’s comprehensive geophysical well log analysis workfow.
Rock physics modeling will assess the seismic AVO response to changes in fuid saturation.
In addition, RSI will deliver a suite of rock
physics templates based on the study wells.
RPTs are utilities that facilitate the prediction of lithology and hydrocarbons from well
log and inverted seismic data by combining depositional and diagenetic trends with
fuid substitution so that both lithology and
fuid effects are considered. The fnal set of
deliverables will be a reference tool for understanding reservoir property signatures
in seismic data.
Active geophysical surveys hit hot spots
CGG has received a contract from
Anadarko Petroleum and partner Ecopetrol
to acquire and process 5,500 sq km ( 2, 124
sq mi) of 3D BroadSeis seismic data on the
Caribbean coast offshore Colombia. This is
the largest marine seismic program ever acquired in Colombia and the frst proprietary
BroadSeis survey to be conducted in the
country, said CGG.
The survey, covering portions of the Col 5,
Ura 4, Fuerte Norte, Fuerte Sur, and Purple
Angel blocks, will be acquired by the CGG
Viking towing a 10 x 100 x 7,050 m spread
in a BroadSeis confguration using steerable
Sercel Sentinel solid streamers and CGG’s
proprietary Dovetail acquisition designed to
provide more regular sampling and reduce
infll. The survey will start in 3Q 2013 and
is expected to take four months. The survey
data set will be processed in CGG’s Houston
Electromagnetic Geoservices has a letter of
intent to extend its on-going $35-million contract in Asia. The contract extension will bring
the total contract value to at least $50 million.
It is expected that the vessel BOA Thalassa will
complete the entire program, including the
contract extension, in October 2013.
Petroleum Geo-Services is in the process of acquiring a new GeoStreamer Multi-Client 3D marine seismic survey (Caswell MC3D) in the Browse basin offshore Western
Australia. The Caswell MC3D survey will cover 15,000 sq km ( 5,792 sq mi). The approval area covers several exploration permits where there has been recent drilling
success in addition to three of the 2013 release areas (W13-1, 2, and 3) and adjacent
open acreage. The survey is expected to last into December 2014. For more information about seismic surveys under way or planned, see active geophysical survey
work elsewhere on this page.
Petroleum Geo-Services and TGS are
back offshore eastern Canada for the third
year to complete acquisition of a 2D multi-client survey off Newfoundland. The current program will acquire additional data
over approximately 16,000 line km ( 9,942
mi) of the Northeast Newfoundland Slope.
Final processed data will be available in
spring of 2014.That will bring the total survey to 46,000 line km (28,583 mi) off Newfoundland and Labrador. •
