The Saudi Aramco spokesman appears to be saying that they
project a two percent decline from existing fields despite
all efforts to maintain production.

obscure but telling piece.
Saudi Aramco boosts drilling efforts to offset declining fields
Saudi Aramco's mature crude oil fields are expected to decline at a gross
average rate of 8%/year without additional maintenance and drilling, a Saudi
Aramco spokesman said Tuesday.
But Saudi Aramco has taken a number of measures to offset a decline in
output from the country's aging oil fields, the spokesman added.
"A variety of remedial activities are always being taken in oil fields
influencing their effective decline rates," the spokesman said. "The drilling
of additional development wells in the producing fields is Saudi Aramco's
standard practice to offset normal declines of older wells."
This is particularly important when oil fields are progressively depleted
under a well thought out strategy of maximizing the sweep and displacement
efficiencies, leading to high ultimate oil recovery, the spokesman said.
"This maintain potential drilling in mature fields combined with a
multitude of remedial actions and the development of new fields, with long
plateau lives, lowers the composite decline rate of producing fields to around
2%," the spokesman said.
Underscoring these efforts, Saudi Aramco signed two contracts with J. Ray
McDermott Middle East and McDermott Arabia Company Ltd, subsidiaries of J. Ray
McDermott, to detail design, procure, fabricate, transport and install
offshore facilities for the Maintain Potential and Khursaniyah Upstream
Pipeline programs, Saudi Aramco said April 6.
The first contract includes two drilling support structures in Zuluf
field to be installed in December 2006 and one new wellhead production
platform in the Central Safaniya oil field to support onstream start-up in May
2007, Saudi Aramco said.
Three additional wellhead platforms will be installed in the Central
Safaniya and Zuluf fields by December 2007. New associated flowlines will
connect these platforms to existing offshore tie-in (manifold) platforms.
To support increasing production in the Central Safaniya field, a new
tie-in platform (Safaniya TP-18) will also be engineered, procured, fabricated
and installed by December 2007, along with a 24-inch trunkline between it and
a subsea connection on the new 42-inch trunkline flowing to the onshore
Safaniya GOSP-1, installed under a separate contract.
The second contract is associated with the subsea portion, some 22 km (14
miles) long, of the 30-inch gas pipeline from Abu Ali Island to an onshore
site at Khursaniyah to be installed by May 2007.
This subsea portion is part of the new 66 km BKTG-1 pipeline that will
transport 220 million cubic feet/day of gas from Abu Ali Plant to Khursaniyah
