OGX Petroleo e Gas has completed drilling well 1-OGX-23-RJS in the BM-S-58 block, in the shallow waters of the Santos Basin, offshore Brazil.

The well is situated about 107km off the coast, at a water depth of approximately 152m.

The well was drilled to test reservoirs in adjacent structures to the discovery in the 1-OGX-19A well.

OGX-23 hit reservoirs with evidence of hydrocarbons, but they were considered to be non-commercial and the drilling of this well reached a total depth of 5,623m.

The Ocean Quest rig initiated drilling at the well in October 2010.
