Upstream set for slow revival

Wood Mackenzie’s latest market overview predicts a revival in global upstream spending in 2011, with investments climbing thereafter to around $350 billion in 2012. This is still down on last year’s five-year peak of $370 billion.

The First Hints of Recovery in Global Spending claims that in the current economic climate, the industry will continue to favor regions offering low political risk and fiscal stability, namely the US, Canada, Australia, and parts of Europe. Investments by national oil companies, which have sustained the few pockets of growth in countries such as Brazil, Saudi Arabia, and Abu Dhabi, should hold steady at around $100 billion/year in real terms over the next five years.

Americas

Pemex has discovered oil in the Leek structure, its first deepwater well this year in the Mexican sector. The company plans to step up this activity next year by taking delivery of two deepwater rigs.

Recently, Pemex contracted CGGVeritas for the country’s largest ever deepwater seismic survey, comprising over 75,000 sq km (28,958 sq mi) of 3D data. Analysts believe this area could hold up to 30 Bboe, more than half Mexico’s estimated remaining reserves.

In the shallow water Mexican sector, Cameron will provide 16 multiphase pumping systems for installation on three platforms on the KuMaloobZaap field under an $86-million contract. The pumps will be manufactured by Leistritz in Germany, and will be designed to raise pipeline delivery pressure and crude production rates. They are due to be installed in 2011.

BP Trinidad and Tobago has produced first gas from its Savonette field 50 mi (80.5 km) offshore southeast Trinidad. Savonette has been developed by the fourth in a series of normally unmanned “clone concept” platforms. The 1,898-metric ton (2,092-ton) jacket and 871-metric ton (960-ton) topsides were both built at the Trinidad Offshore Fabricators yard in La Brea.

BP’s normally unmanned Savonette platform, the fourth in a series of standardized designs offshore Trinidad.

Production, averaging 600 MMcf/d of gas with associated condensate, is routed to the Mahogany B platform for processing via a 26-in. (66-cm), 5.3-mi (8.5-km) subsea pipeline. From there it heads via existing infrastructure to Atlantic LNG’s liquefaction plant.

Petrobras has found further oil with its latest well in the Santos basin pre-salt Tupi evaluation area. Tupi North-East was drilled in 2,115 m (6,399 ft) of water, 18 km (11.2 mi) northeast of the Tupi discovery well. According to partner BG Group, the well penetrated a 250-m (820-m) thick section of carbonate reservoirs, wireline tests confirming the presence of 28º API oil.

The result supports estimates of 5-8 Bboe recoverable within the Tupi accumulation, BG adds. Drillstem tests were to be conducted on the latest discovery to evaluate reservoir productivity.

In the Campos basin, Subsea 7 will fabricate and install new gas and oil export lines with a total length of 80 km (49.8 mi) for the latest phase of Petrobras’ Roncador development. The pipelines will connect the P-55 and PRA-1 platforms: installations should get under way in the second half of next year.

Shell plans to drill two exploration wells next summer in the Beaufort Sea off Alaska using the drillshipM/V Frontier Discoverer. The US Department of the Interior Minerals Management Service (MMS) has approved the plans for leases 195 and 202, subject to conditions. The proposed drilling area is confined to the far western part of Camden Bay, and also involves use of a tending ice management vessel.

Mediterranean Sea

Australian company Cooper Energy is aiming to develop the shallow water Hammamet West oil field in the Gulf of Hammamet. The field, discovered in 1967, lies within the Bargou exploration permit awarded to Cooper in 2005. Two wells proved oil within the Birsa sandstone formation and the deeper Abiod carbonate formation.

Cooper estimates oil in place at over 200 MMbbl, but needs improved structural definition before committing to development. CGGVeritas was due to acquire 3D seismic over the structure this month, the results of which will be used for a third well (Hammamet-3), expected to cost $20-30 million to drill. The currently favored development concept is a small, normally unmanned, platform exporting oil and gas to the mainland via a multi-phase pipeline.

West Africa

Shell has contracted Saipem to engineer and install subsea facilities for the deepwater Bonga North-West development off Nigeria. The field, in license OML 118, will be produced through 12 subsea wells connected to the existing Bonga infrastructure. Saipem’s scope includes 32 km (19.9 mi) of pipe-in-pipe flowlines, water injection lines, and umbilicals. The pipelay vesselsSaipem FDS and Saipem 3000 will perform the bulk of the installations during 2012–2013.

Also in Nigeria, local company Oando has agreed with Gazprom for joint development of oil and gas assets and infrastructure in the Gulf of Guinea and sub-Saharan West African regions.
