Maintaining a steady level of exploration activity, OGX has marked a number of successes.

The Itacoatiara well, or OGX-79, found a hydrocarbon column of about 150m with 64m of net pay in the Albian section in the Campos Basin. The block BM-C-39 well, drilled in 102m of water, is 100% operated by OGX, which announced the find in April 2012.

The Fortaleza, or OGX-63, well intersected a hydrocarbon column of 1000m in the Albian with about 110m of net pay. The well, in 155m of water, is in block BM-S-57 in the Santos Basin. OGX, which operates with 100% interest, confirmed the find in January 2012.

OGX delivered its first shipment to Shell Western Supply & Trading from the FPSO OSX-1 this March.

The Tupungato, or OGX-20, well in 130m of water in block BM-C-41 found an 80m oil column with about 50m of net pay in the Albian section. OGX, which operates the block with 100% interest, announced the Albian find in October 2011.

A September 2011 drillstem test on OGX-11D in the Natal accumulation indicated a production potential of 1mmcm/d and 1200b/d of 47°API condensate in a vertical well and up to 5mmcm/d and 6000b/d of 47°API condensate with a horizontal well. The well in Santos Basin block BM-S-59 is in 180m of water. OGX operates the block with 100% interest.

The Tambora, or OGX-52, well found 174m of hydrocarbon column with 96m of net pay in the Albian section and a 12m hydrocarbon column with 5m of net pay in the Santonian. The well was drilled in 130m of water in block BM-C-41, which OGX operates with 100% interest. OGX announced the find in July 2011.

The Maceió, or OGX-47, well in Santos Basin block BM-S-59 found a hydrocarbon column of 131m in the Santonian section with about 51m of net pay. The well, drilled in 185m of water, was announced in July 2011. OGX operates the block with 100% interest. A later drillstem test, with three production intervals, indicated a production potential of 1mmcm/d in a vertical well, which could reach 2.5mmcm/d in a horizontal well, both at absolute open flow, OGX said.

The Salvador, or OGX-30, well found a 330m hydrocarbon column in the Albian age. The well, in Santos Basin block BM-S-58, was drilled in 150m of water. OGX announced the find, which it operates with 100% interest, in May 2011.

OGX-36, an appraisal of the Pipeline accumulation in Campos Basin block BM-C-41, hit 136m of oil column with 60m of net pay. Operator OGX (100%) confirmed the find, in 128m of water, in March 2011.

The Osorno, or OGX-31, well in block BM-C-41 hit an oil column of 149m with 48m of net pay in the Albian and a 59m column with 23m of net pay in the Aptian. The Campos Basin well in 135m of water is operated 100% by OGX, which announced the find in March 2011.

The Carambola-B well in Maersk Oil-operated block BM-C-37 found up to 17m of potential net pay in the Albian section. The well is in 130m of water in the Campos Basin. OGX announced the find in February 2011. At the time of discovery, Maersk Oil operated BM-C-37 with 50% on behalf of OGX with 50%. In a March 2012 deal, OGX acquired an additional 20% interest from Maersk as well as the operatorship of the block.

The Illimani, or OGX-28D, well found a 52m hydrocarbon column with 24m of net pay in the Albian. The well, in Campos Basin block BM-C-41, is in 125m of water. OGX, operator with 100%, announced the discovery in January 2011.

The OGX-25 well in block BM-C-39 found a 198m column with total net pay of 145m in the Albian and Cenomanian sections and additional pay in the Eocene. OGX operates the block with 100% interest and announced the Eocene discovery in January 2011.

Maersk Oil found 14m of potential net pay in the Santonian as well as 43m of potential net pay in the Albian and 12m of potential net pay in the Aptian sections of a Campos Basin BM-C-37 well in 135m of water. OGX announced the find in January 2011. At the time of discovery, Maersk Oil operated BM-C-37 with 50% on behalf of OGX with 50%.
