| Anadarko Transfers Partial Interest in Heidelberg |
Date: Mar. 2013
Type: Operator Update |
| Anadarko announced it signed an agreement with an undisclosed party to enter into a carried interest arrangement for a portion of the company's ownership in the deepwater Heidelberg development in the US Gulf of Mexico. Under the agreement, Anadarko will be carried for $860 million, which represents nearly all of its expected capital requirements through first oil which is anticipated in mid-2016. In exchange, Anadarko will transfer a 12.75 percent working interest in the development. The company will continue as operator with a 31.5 percent interest. The agreement is subject to customary closing conditions but should close in April 2013. Heidelberg is estimated to contain 400 million barrels of recoverable resources. |

| Anadarko Further Appraises Heidelberg |
Date: Apr. 2012
Type: Appraisal Operations |
| Anadarko has further appraised the Heidelberg discovery in the deepwater Gulf of Mexico after drilling two appraisal wells (GC 903-3 and GC 903-3ST1). The two wells were drilled in order to appraise the extension of the Heidelberg discovery made in 2009. The Heidelberg appraisal well GC 903-3 was drilled in a water depth of 5,260 feet (1,603 meters) and reached a total depth of 31,030 feet (9,460 meters) of measured depth. The well was sidetracked down dip (GC 903-3ST1 well) to a total depth of 30,440 feet (9,278 meters) of measured depth, indicating an oil water contact at approximately 700 feet (213 meters) deeper than the previous oil discovery well and significantly increasing the field's aerial extent. Estimated recoverable resources could reach 200 million barrels of oil. Data is being evaluated in order to accelerate the overall sanctioning process for this project. |

| Anadarko Hits Additional Pay in Heidelberg |
Date: Feb. 2012
Type: Appraisal Operations |
| Anadarko Petroleum has successfully appraised the Heidelberg-2 appraisal well, located in Green Canyon Block 903 in the deepwater GOM. Heidelberg-2 encountered about 250 net feet (76 meters) of oil pay in high-quality Miocene sands. The appraisal well was drilled to a total depth of 31,030 feet (9,458 meters) in about 5,000 feet (1,524 meters) of water, about 1.5 miles (2.4 kilometers) south and 550 feet (168 meters) structurally updip from the Heidelberg discovery well. Log and pressure data from the appraisal and discovery wells indicate excellent quality, continuous and pressure-connected reservoirs with the same high-quality oil. Anadarko plans to immediately sidetrack the well to evaluate the down-dip extent of the field, and plans to initiate pre-FEED activities to prepare for sanctioning a development plan, stated the operator. |
