Appraisal drilling underway at Hammerhead


Appraisal drilling is underway at the Hammerhead field in the Stabroek Block offshore Guyana as US oil major ExxonMobil continues to assess discoveries and expands its operations in the South American country.

Guyana Maritime Administration Department said this week ExxonMobil affiliate Esso Exploration and Production Guyana Limited commenced drilling at the Hammerhead-2 well site on April 17. The exercise, which will incorporate the use of 14 vessels, will be conducted 90 nautical miles off Guyana’s coast over an area 1 square kilometer.

The Maritime Administration notice came just days before ExxonMobil and its co-venture partners Hess and CNOOC announced their 13th discovery at the Stabroek Block at the Yellowtail-1 well, located approximately 6 miles (10 kilometers) northwest of the Tilapia discovery.

Yellowtail-1 encountered approximately 292 feet (89 meters) of high-quality oil-bearing sandstone reservoir and was drilled to a depth of 18,445 feet (5,622 meters) in 6,046 feet (1,843 meters) of water.
