              BP PLANS $3 BILLION PROJECT TO REFINE MORE CANADIAN
                     HEAVY CRUDE OIL IN THE U.S. MIDWEST


Investment at Whiting, Indiana refinery also brings potential to add about 1.7
million US gallons per day of motor fuels

Whiting, Indiana -- BP announced today that it has entered the final planning
stage of a $3 billion investment in Canadian heavy crude oil processing at its
Whiting Refinery located in northwest Indiana.

BP America Inc. Chairman and President Bob Malone said the company intends to
reconfigure its Whiting Refinery so most of its feedstock can be heavy Canadian
crude oil.  Reconfiguring the refinery also has the potential to increase its
production of motor fuels by about 15 percent, which is about 1.7 million
additional gallons of gasoline and diesel per day.

"BP is pleased to invest in a project important to the economies of both the
United States and Canada," Malone said.  "BP's investment increases the
diversity and security of oil supplies that can be refined into gasoline, diesel
and other petroleum products in demand by consumers in the Midwestern United
States.  It also provides a significant market for Canada's abundant heavy crude
oil resources."

The Whiting Refinery currently produces about 4.5 billion gallons of
transportation fuels each year, enough to supply more than 5 million vehicles.
"After our investment, the refinery will have the potential to supply motor
fuels to about 6 million automobiles," Malone said.

Construction of the project is tentatively scheduled to begin in 2007 and be
completed by 2011, pending regulatory approvals.

Speaking at a briefing held today in Indiana with Indiana Governor Mitch Daniels
and other government and business leaders, BP's Group Vice President for
Refining Mike Hoffman said the Whiting Refinery is optimally located in the U.S.
Midwest and has substantial capacity for reconfiguration as well as effective
infrastructure to support this project.

"The planned investment will modernize the refinery with equipment of
significant size and scale and competitively reposition it as a top tier
refinery well into the future," Hoffman explained.  "Following our most recent
review of project plans, BP is proceeding with detailed engineering, permitting
and procurement to progress this project to construction by the end of next
year."

"During this final planning period, we will continue to detail and align
construction and refinery operations plans to ensure both are conducted safely,"
Hoffman said. "We also will conduct a rigorous inspection program to ensure that
replacement and reconfigured equipment meets or exceeds industry standards and
our expectations for ongoing integrity and reliability of refinery operations."

"We appreciate BP's choice of Indiana for this massive, landmark project," said
Governor Daniels. "In capital investment this is the largest we've had, and more
construction workers will be hired for this project than to build the new
Indiana Stadium and Convention Center. The eyes of the whole state are on
Northwest Indiana today, as they should be. This marks another huge step in
Indiana's economic comeback."

The project will increase capacity for coking, hydrogen production,
hydrotreating and sulfur recovery.  The replacement processing units and
enhancements to existing refinery units will increase Canadian heavy crude oil
processing capability by about 260,000 barrels per day.

Hoffman reported that BP continues to make progress to complete agreements with
providers for heavy oil production, pipeline access, engineering, procurement
and construction.

Dan Sajkowski, BP Whiting Refinery Manager and Vice President of BP Products
North America Inc., said the company's planned investment is expected to create
jobs for approximately 2,500 workers during the peak of its three-year
construction phase and 60 to 80 permanent full-time employees to operate
enhanced processing units and other refinery improvements.

"We are fortunate that Northwest Indiana has an experienced workforce that can
support a major construction project such as the one we have planned," Sajkowski
said.

State and local government support of economic development and infrastructure
improvement also enables this investment in Indiana, according to Sajkowski.
"We appreciate the attractive business environment provided by the State of
Indiana and the cities of East Chicago, Hammond and Whiting."
