UK - FIRST GAS FROM KELVIN FIELD (Tullow 22.5%) Natural gas production from the Kelvin field commenced on 15 November 2007 at agross rate of 103 mmscfd on a 30% choke. The Kelvin field development consists of a single well, a minimum-facilitiesplatform and a 12 kilometre pipeline that connects to the Tullow-owned CMSinfrastructure at Murdoch. The development also acts as a potential tie-in pointfor the nearby K4 and Harrison discoveries. The project has been completed under budget, ahead of schedule and just twoyears after the field was discovered. UGANDA - NGASSA-1 DRILLING AND MPUTA-4 WELL TEST COMMENCED (Tullow 100%) The Ngassa-1 exploration well in Block 2 Uganda commenced drilling on 17November 2007. The well is being drilled by the Nabors 221 rig and will testthe high impact Ngassa prospect which is located beneath Lake Albert. The Nabors221 rig has been specifically mobilised to the region in order to drill deepprospects located under the lake from onshore locations. Drilling startup was delayed as a result of heavy rain which slowed constructionon the drill site. The well has a planned length of 4,900 metres and isexpected to take approximately 110 days to reach the primary target. The wellhas already been drilled to a depth of 311 metres. Poor weather conditions have also impacted the start of the Mputa-4 well test.This extended flow test commenced on 21 November and interpreted results areexpected in early December. GABON - M'PANO-1 WELL PLUGGED AND ABANDONED (Tullow 40%) The onshore M'Pano-1 well in the Nziembou licence which commenced drilling on 2October 2007 reached a total depth of 1,500 metres on 13 November 2007. Despiteconfirming the presence of the primary Gamba formation, these reservoirs werenot hydrocarbon bearing. The well's secondary objectives, whilst possibly oilbearing, had no reservoir quality sands and so the well has been plugged andabandoned.
