| Zaedyus-2 Proves Non-Commercial |
Date: Dec. 2012
Type: Drilling Operations |
| Shell's Zaedyus-2 appraisal well offshore French Guiana failed to locate commercial quantities of hydrocarbons in spite of intersecting 287 net feet of reservoir quality sands. Logging and data sampling results indicate that the Zaedyus-2 reservoirs are not in communication with those discovered in the Zaedyus-1 well a little more than three miles away. Future drilling of the Zaedyus fan system will likely target the down-dip elements of Zaedyus Deep. The well was drilled to a total depth of 20,341 feet by the Stena Drillmax ICE (UDW drillship). Once logging operations are complete, the rig will sail to the next well in the four-well drilling program. |

| Shell Begins Drilling Activities in Guyane Maritime Permit |
Date: Jul. 2012
Type: Drilling Operations |
| Shell has spud the GM-ES-2 well at its Guyane Maritime permit using the Stena DrillMax ICE (UDW drillship). The well, which is located in 6,200 feet (1,890 meters) of water, is being drilled to delineate the Zaedyus discovery. |

| Shell to Appraise Zaedyus |
Date: Apr. 2012
Type: Appraisal Operations |
| Northpet announced that the Zaedyus consortium plans to commence drilling in mid-2012 on the Guyane permit, to follow-up on the Zaedyus oil discovery in late 2011. Appraisal drilling is planned to delineate the discovery. Shell, who took over as operator of the license, has contracted the Stena DrillMax ICE (UDW drillship) to commence operations mid-year subject to government consent. |

| Shell, Total to Appraise Zaedyus Discovery in 2012 |
Date: Mar. 2012
Type: Status Update |
| Total, a partner on the Zaedyus discovery, plans to conduct an extensive drilling campaign, in the Guyane Maritime License offshore French Guiana, and a further 3D seismic survey in 2012. The license contains the Zaedyus discovery in a water depth of 6,719 feet (2,048 meters). |

| Tullow Sidetracks Zaedyus Offshore French Guiana |
Date: Nov. 2011
Type: Drilling Operations |
| Tullow Oil is currently sidetracking the Zaedyus exploratory well (GM-ES-1) in the Guyane Maritime Permit. Drilling of the sidetrack well is occuring to recover reservoir cores with completion of operations expected in mid-November. The consortium is working on the 2012 drilling program and anticipates it will include 3D seismic and the drilling of two wells. This program should begin in mid-2012 once all the necessary approvals have been obtained. Shell should obtain operatorship of the block in early 2012, subject to Government and Joint Venture agreements. The consortium consists of Shell (45 percent), Tullow (27.5 percent), Total (25 percent) and Northpet (2.5 percent). The Guyane Maritime License is operated by Tullow with a 27.5% interest. Partners in the license include Shell (45%), Total (25%), and Northpet (2.5%). |

| Tullow Finds Oil in French Guiana |
Date: Sep. 2011
Type: New Discovery |
| Tullow Oil made an oil discovery in the Zaedyus exploratory well (GM-ES-1) offshore French Guiana. The well encountered 236 feet (72 meters) of net oil pay in two turbidite fans. Drilling results, wire line logs and samples of reservoir fluids show that the well found good-quality reservoir sands on prognosis. The well, situated in a water depth of 10,000 feet (3,048 meters), reached a depth of 18,737 feet (5,711 meters). Exploratory drilling will continue, and the well will deepen to a depth of 19,685 feet (6,000 meters) to calibrate the deeper geology. Tullow will then likely sidetrack the well to allow cores to be obtained over the reservoir sections. Drilling operations are being performed in the Guyane Maritime license using the ENSCO 8503 semisub.
The Zaedyus discovery unlocked a new hydrocarbon basin within several neighboring prospects that were mapped, so the operator will now consider performing an appraisal program and an extensive follow-up with exploration activities. The Guyane Maritime License is operated by Tullow with a 27.5% interest. Partners on the license include Shell (45%), Total (25%), and Northpet (2.5%). |

| Tullow Spuds Zaedyus Prospect in Guyane Maritime Permit |
Date: Mar. 2011
Type: Drilling Operations |
| Tullow announced that drilling operations have commenced on the Zaedyus prospect with well GM-ES-1 in the Guyane Maritime permit. The ENSCO 8503 semisub will drill the GM-ES-1 well to a total depth of 21,325 feet (6,500 meters), targeting one of several prospects in major undrilled Late Cretaceous deep water channel fan systems. Tullow believes that the prospect has an estimated P10 prospective resource of 700 million barrels and is geologically analogous to its Jubilee field, located off the coast of Ghana. Zaedyus is located offshore Guyane about 31 miles (50 kilometers) from the boundary with Brazil. The partners in the Guyane Maritime license are Tullow (operator, 27.5%), Shell (45%), Total (25%), and Northpet Investments Limited (2.5%). |

| Tullow Plans to Spud Zaedyus Prospect in 1Q11 |
Date: Jan. 2011
Type: Status Update |
| Northern Petroleum, a partner on the Guyane Maritime Block offshore French Guiana, announced that recently acquired and processed 3D seismic data have identified a portfolio of Upper Cretaceous Jubilee-type prospects and leads. The partnership on the license have contracted the ENSCO 8503 semisub, and expect to drill the Zaedyus prospect in 1Q 2011. The partners in the Guyane Maritime license are Tullow (operator, 27.5%), Shell (45%), Total (25%), and Northpet Investments Limited (2.5%). |

| Tullow Pinpoints Prospect Offshore French Guiana |
Date: Nov. 2010
Type: Status Update |
| Recently acquired 3D seismic survey in the Guyana Basin offshore French Guiana has pinpointed a deepwater prospect, which will be drilled in the first quarter of 2011. In September, Shell exercised its option, pending governmental approval, to increase its interest in the Guyane Maritime block, containing the prospect, by 12% to 45%. This will result in Tullow decreasing its interest to 27.5%. Tullow will be carried by both Shell and Total for the majority of the costs associated with the 3D seismic and the forthcoming Zaedyus exploratory well. |

| Total Farms Into Tullow's French Guiana Acreage |
Date: Dec. 2009
Type: Acreage Acquisition |
| Total farmed in to the Guyane Maritime Permit and acquired a 25% interest from Tullow Oil plc. The permit is located 93 miles (150 kilometers) off the coast of the French Guiana and spans an area of 7,907 acres (32,000 square kilometers) in water depths ranging from 6,562 to 9,843 feet (2,000 to 3,000 meters).

| Tullow Kicks Off 3D Seismic Offshore French Guyane |
Date: Sep. 2009
Type: Operator Update |
| Northern Petroleum announced that seismic operations have commenced on the Guyane Maritime license, which is operated by Tullow Oil. The Guyane Maritime license covers some 8 million acres (35,200 square kilometers) of the prospective area offshore French Guyane in water depths ranging from 656 to 9,843 feet (200 to 3000 meters). Interpretation of existing seismic and well data indicates the presence of several large structural and stratigraphic prospects with potential to contain significant hydrocarbon volumes. The 2009 3D seismic program will acquire data across an area covering approximately 617,763 acres (2,500 square kilometers). The seismic acquisition should be complete before year end 2009. |
