its first well, with a view to capitalizing on currently lower rig rates.
ExxonMobil and partners Hess and CNOOC Nexen Petroleum
have sanctioned the $3.2-billion first-phase development of the Liza
oil field, 200 km (124 mi) offshore Guyana. Following strong results
from the latest appraisal well, Liza- 4, recoverable reserves across the
block now stand at 2-2. 5 Bboe. SBM Offshore will supply a leased
FPSO – a converted VLCC – to be spread-moored in 1,525 m ( 5,003 ft)
of water, and producing up to 120,000 b/d of oil from 17 wells linked
to four subsea drill centers, with associated gas treatment and water
injection capability. First oil should follow by 2020.
Repsol has commissioned a 4,000-sq km ( 1,544-sq mi) 3D seismic
survey over the offshore Kanuku license, updip of Liza, while Tullow
Oil expects to spud the Araku- 1 exploration well offshore neighboring
Suriname this fall.
Petrobras and China’s CNPC plan to jointly evaluate opportunities
both in Brazil and elsewhere, jointly applying their strengths across
all segments of the oil and gas chain. The two companies have been
partners since 2013 in the production-sharing agreement for the
deepwater presalt Libra area in the Santos basin offshore Brazil.
In the southeastern part of the Campos basin, Petrobras has offered
for sale its 70% operated interest in the heavy-oil Maromba field in the
shallow-water BC-20A concession, close to the producing Peregrino
field. Chevron is the other partner.

the coast, is close to ceasing production.
The Gambia’s government has approved
FAR’s assumption of an 80% operated stake
in offshore blocks A2 and A5, with current
incumbent Erin Energy retaining 20%. FAR
will part-carry Erin for the costs of the first
exploration well, likely to be drilled in 2018.
Both blocks are next to and on trend with
the SNE oilfield off Senegal to the north,
with large shelf-edge prospects identified
from 3D seismic. Water depths range from
50-1,200 m (164-3,937 ft).
NNPC, First Exploration & Production, and Schlumberger have
agreed to jointly develop the shallow-water Anyala and Madu fields in
the Niger Delta, 40 km ( 25 mi) offshore Nigeria. Schlumberger would
provide technical ser vices and capital in kind until first oil, anticipated
in 2019. The phased development, estimated to cost $700 million, would
make use of an existing FPSO with oil and gas processing capacity.
Equatorial Guinea’s government has awarded Irish independent
Clontarf Energy deepwater block 18 under the nation’s 2017 Bid
Round. It covers 5,056 sq km ( 1,952 sq mi) of undrilled acreage
within the Northern Rio Muni basin – Clontarf’s initial focus will be
on structural/stratigraphic traps in Cretaceous sands plays.
The world’s first converted floating liquefaction vessel should have
departed Keppel Shipyard in Singapore for Cameroon. Owner Golar
LNG will deploy the Hilli Episeyo, formerly a 1975-built Moss LNG
carrier, on the Sanagud Sud and Ebome gas fields offshore Kribi for
Perenco and state-owned Société Nationale des Hydrocarbures. The
converted vessel has storage capacity of 125,000 cu m ( 4. 41 MMcf),
with sponsons fitted on both sides of the hull to house liquefaction
and gas compression equipment.
Keppel Shipyard is currently converting the M/T Tempera into an
FPSO for deployment on Perenco’s Yombe field offshore Republic
of Congo, to the south. It will replace the FPSO Conkouati that has
operated on Yombe for more than 25 years.
BP is exiting block 24/11 offshore Angola after deciding that its
2014 Katambi gas discovery is not commercial.
Rosneft has discovered oil in the Laptev Sea via the Tsentralno-
Olginskaya well, drilled horizontally from the shore of the Khara-Tumus Pensinsula in Khatanga Bay, nor th of the Karsnoyarsk region.
Analysis of core samples taken from subsurface depths of 2,305-2,363
m ( 7,562-7,752 ft) showed high levels of oil saturation.
Farther to the east in the Sea of Okhostk, the semisubmersible
Hakuryu- 5 has been drilling the first explorator y well for Gazpromneft
Sakhalin on the Ayashky license block. The rig has been winterized
with drilling mud used from the outset, along with a system for riser-free sludge disposal, to assist wellbore stability.
Allseas’ Pioneering Spirit has started deepwater pipelay for Gaz-
prom’s TurkStream gas lines in the Black Sea: each will have through-
put capacity of 15.75 bcm/yr. Allseas’ Auda-
cia has been constructing the shallow-water
section near the Russian coast.
Wood Group is performing front-end en-
gineering and design (FEED) for Gastrade
for the Alexandroupolis Independent Natu-
ral Gas System project offshore Greece.
This will feature a floating LNG and regasification (FSRU) vessel, providing a new gas
supply source to markets in southeast and
central Europe. An investment decision
should follow in late-2017.
Greek independent Energean has sub-
mitted a field development plan to Israel’s
