Successful appraisal well in the pre-salt of block BM-C-32 in Brazil

 

 

The Consortium of block BM-C-32 in Brazil, operated by BP - British Petroleum (NYSE:BP,LON:BP) that owns 40%, Anadarko (NYSE:APC,FRA:AAZ), with 33.3% and Maersk Oil (CPH:MARSK B,PINK:AMKBF) with the remaining 26.7%, announced today (November 9, 2011) the successful Itaipu-2 pre-salt appraisal well.

 

 

 

 

Located in block BM-C-32 in the Campos Basin offshore Brazil, the well was drilled to total depth of approximately 4,877 meters in 1,420 meters of water, and encountered a gross petroleum column of approximately 18 meters in a pre-salt carbonate reservoir.

 

 

According to Anadarko’s press release of December 17, 2009, originally this consortium was operated by Devon Energy Corp. (NYSE:DVN) with 40% working interest, Anadarko with 33.3% and SK Energy Co., Ltd. (Private) holds the Remaining 26.7% working interest.

 

 

 

 

“The pre-salt Itaipu-2 well is an aggressive stepout from the Itaipu discovery well, which is located 4 miles (7 kilometers) northwest,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said. “The Itaipu-2 well established a fluid contact and appears to have successfully extended the accumulation 120 meters downdip from the discovery. Accordingly, the appraisal well significantly increases the areal extent of the vast Itaipu field, and we believe incorporating the data from both the appraisal well and the original discovery well we will increase our previous resource estimates for the field. We are very pleased with these results and look forward to continuing our activity on the block.”

According to Text II, the pre-salt Itaipu-2 well is an aggressive step-out from the Itaipu Discovery well because it

  1. has established a way for the fluid to step out of the well.
  2. has been able to extend the field in 120m downdip.
  3. almost reached the amount of Itaipu Discovery well.
  4. is a furious well and aggressively responded with seismic activation.
  5. will encounter a column with a large quantity of gross petroleum together with Itaipu Discovery well.

Gabarito

B

Comentário do professor

A alternativa está correta porque o texto afirma que o poço Itaipu-2 “established a fluid contact and appears to have successfully extended the accumulation 120 meters downdip from the Discovery”.

Ou seja, o poço confirmou o contato de fluido e conseguiu estender o corpo de petróleo em 120 metros downdip em relação ao poço de descoberta.

Em termos geológicos, downdip indica a direção para a parte mais profunda da camada reservatório; estender a acumulação nessa direção significa que a zona com hidrocarbonetos continua além da descoberta inicial.

Esse resultado amplia a área do campo e justifica chamar o poço de um “aggressive step-out”, porque validou e expandiu a acumulação conhecida.

Portanto, a frase do enunciado descreve precisamente que o poço aumentou o campo em 120 m downdip, confirmando a alternativa B.
