1.6 INTSOK priority projects
Block 14 Lianzi, Lucapa, and Negage projects – Chevron
Block 14 is operated by Chevron (31% ownership) with partners Eni (20%), Total
(20%), Sonangol (20%) and Galp Energia (9%).
Block 14 has been through significant development activities in recent years, including
the BBLT complex with the Belize-Benguela (BB) compliant piled tower (CPT) and the
Lobito and Tomboco subsea tie backs to the BB CPT with first oil during 2006. During
the second half of 2009, first oil was produced from the Tombua-Landana CPT.
Chevron contemplates tie back of smaller discoveries to the new infrastructure. The
most advanced opportunity is the Lianzi discovery located within the shared Angola-
Congo Joint Development Area, 25 km west of the BBLT area in 900 m water depth.
The expected development solution is subsea tie back to the BB platform. Chevron
awarded FEED contract for the subsea system connecting pipelines and topsides
modifications on the BB platform to Granherne in 2008. Preliminary requirements are
expected to include 3 production and 3 water injection wells, 1 each of contingency
production and injection wells, and 45 km pipelines to the BB platform. Peak
production of 40 kbblpd is expected by 2014, subject to final investment decisions.
The second opportunity in Block 14 is the Lucapa field, located in 1,200 m water
depth. Chevron is expected to award a pre-FEED contract to assess 3 potential
development scenarios including standalone FPSO, TLP with FSU, and TLP with
FPSO. Partner Galp Energia expects the project to come online 2014 at rate of 100-
130 kbblpd. Chevron plans for FEED award by end 2010.
The third opportunity is the Negage discovery from 2002 in the southwest portion of
Block 14, located in 1,450 m water depth. Uncertainty on the reserves size and need
for unitization and revenue sharing agreement between Angola and the Democratic
Republic of Congo (DRC) continues to delay the project investment decisions.
Chevron’s original preference was for a standalone FPSO, with early EOIs issued
2004 for a vessel with 1.5 mbbl storage, processing 75 kbblpd crude and 100 Mcfpd
gas. An alternative solution is now though to include a 32 km subsea tieback to Eni’s
planned FPSO in Block 15/06.
Block 15 Kizomba Satellites Phase 1 – ExxonMobil
Block 15 is operated by ExxonMobil (40% ownership) with partners BP (26.7%), Eni
(20%) and Statoil (13.3%). Block 15 development activities to date include the
Kizomba A, B, and C FPSOs and has made Block 15 one of the most prolific blocks in
Angola, having produced 1 billion bbl oil by end 2009.
Current development projects in Block 15 include satellite developments with subsea
tie back of additional wells to the FPSOs. Phase I will include production from Clochas
(discovered 2003) and Mavacola (2001) fields with subsea tiebacks of 5-6 wells to
Kizomba A & B FPSOs, targeting 250 mbbl oil reserves, first oil 2013, and peak
production of 140 kbblpd.
ExxonMobil received government approval of the Phase I contractors during 2009.
AMEC carried out FEED, and provided detailed design, procurement and logistics
support services in conjunction with local JV partner Paragon Angola. Saipem won
contracts for pipelines, umbilicals, risers and subsea installation. Oceaneering will
provide electro-hydraulic steel tube umbilicals, while GE Vetco Gray will supply
subsea production equipment, including deepwater tree connectors, manifolds,
jumpers and connectors and controls equipment. Saipem is expected to commence
drilling during 2011.
Future phases for Block 15 include discoveries located near the current FPSO hubs,
such as Bavuca, Reco-Reco, Vicango, Kakocha, and Mbulumbumba. These
discoveries will most likely be tied in to the Kizomba C FPSO.
