HOUSTON, Nov. 22
– Anadarko Petroleum Corp. has a two-zone postsalt oil and gas discovery at its Itauna-1 exploratory well in the BM-C-29 block in the Campos basin off Brazil.

The well is at 15,250 ft and has encountered more than 275 net ft of oil and gas pay in two separate postsalt zones. The company called the discovery substantial and has filed show reports with Brazil’s ANP on the two formations.

Anadarko said, “The already significant postsalt pay count could increase when we perform a bypass to obtain additional information that should address the unconsolidated formations in the existing hole. We are drilling ahead to test two targeted presalt objectives and expect to complete activities in the well by the end of the year.”
The block lies between Vermelho oil field and Anadarko's Wahoo presalt discovery to the north (OGJ, Apr. 12, 2010, Newsletter).

Itauna-1, in 250 ft of water, is to continue to nearly 18,000 ft. The rig will then work for another operator before returning to Anadarko in 2011 for appraisal drilling on the block.

Anadarko operates BM-C-29 with a 50% working interest, and Colombia’s state Ecopetrol owns the other 50% through its affiliate Ecopetrol Oleo e Gas do Brasil Ltda.
