Gulf of Mexico Oil Sheen Status Update
The Hague, April 12, 2012

Following reports of an oil sheen in the vicinity of the Mars and Ursa
production area in the Gulf of Mexico yesterday, a thorough inspection to date
of Shell assets reveals operations in the area are normal with no sign of leaks.
 We have also confirmed there are no well control issues associated with our
drilling operations in the area.
Shell is continuing to cooperate with federal regulators in their efforts to
determine the cause and nature of the sheen, which is estimated to be 6 barrels.

In addition, although we are confident at this time that the sheen did not
originate from Shell operations, out of prudent caution we will continue to
respond to the sheen.  In that regard, the following actions have taken place:
•         Louisiana Responder, Oil Spill Response Vessel (OSRV) is on station
and remains ready to respond
•         Over flights will continue as weather conditions permit
•         Shell has deployed two remote operating vehicles to inspect Shell and
non-Shell infrastructure and search for potential naturally-occurring seeps in
the area.

CAUTIONARY NOTE

The companies in which Royal Dutch Shell plc directly and indirectly owns
investments are separate entities. In this release “Shell”, “Shell group” and
“Royal Dutch Shell” are sometimes used for convenience where references are made
to Royal Dutch Shell plc and its subsidiaries in general. Likewise, the words
“we”, “us” and “our” are also used to refer to subsidiaries in general or to
those who work for them. These expressions are also used where no useful purpose
is served by identifying the particular company or companies. ‘‘Subsidiaries’’,
“Shell subsidiaries” and “Shell companies” as used in this release refer to
companies in which Royal Dutch Shell either directly or indirectly has control,
by having either a majority of the voting rights or the right to exercise a
controlling influence. The companies in which Shell has significant influence
but not control are referred to as “associated companies” or “associates” and
companies in which Shell has joint control are referred to as “jointly
controlled entities”. In this release, associates and jointly controlled
entities are also referred to as “equity-accounted investments”. The term “Shell
interest” is used for convenience to indicate the direct and/or indirect (for
example, through our 23% shareholding in Woodside Petroleum Ltd.) ownership
interest held by Shell in a venture, partnership or company, after exclusion of
all third-party interest.
