Oxy’s success in Qatar helped establish Oxy as
one of the world’s premier companies in enhancing
recovery from mature fields. Since taking over
operation of the offshore Idd El Shargi North Dome
(ISND) oil field, Oxy has successfully reversed nearly
25 years of steadily declining production. The field
went into production in 1963 and peaked at 50,000
barrels per day in 1970. When Oxy took over the
operation in October 1994, average daily production
had fallen to 20,000 barrels. With the application
of advanced drilling systems and new technologies,
Oxy was able to boost production to a peak above
100,000 barrels per day, more than double the
previous record.

The ISND field has an estimated 4 billion barrels of
remaining oil in place. Through the application of
waterfloods, innovative drilling techniques and stateof-
the-art reservoir characterization, Oxy is maximizing
recovery rates and adding new reserves. In 2005,
Oxy added major new processing facilities to the
existing PS-1 offshore platform doubling the fluid
handling capacity. The platform addition is a remarkable
technical achievement. Its topside weight is more
than 8,000 tons and it has enabled Oxy to increase
power generation five-fold and more than double gas
compression, water injection and separation capacity.
Oxy’s successful redevelopment of ISND resulted in
the Government of Qatar awarding Oxy a production
sharing contract for the Idd El Shargi South Dome
(ISSD) field, 15 miles south of ISND.

With the application of advanced drilling systems and new technologies, Oxy was able to boost production to more than 138,000 barrels per day, nearly three times the previous peak achieved a quarter of a century earlier. Oxy’s success in Qatar helped establish Oxy as one of the world’s premier companies in enhancing recovery from mature fields through the application of new technology and state-of-the-art reservoir modeling techniques. Since 1994, Oxy, in partnership with QP, has produced more than 200 million gross barrels of oil from ISND.

Oxy’s successful redevelopment of ISND resulted in the Government of Qatar awarding Oxy a production sharing contract for the undeveloped Idd El Shargi South Dome field, 15 miles south of ISND. Oxy first began production from ISSD in October 1999 and has begun full field development under a separate agreement.
