Tullow Oil PLC13 March 2006 News release Tullow Oil plc - Uganda: Block 2 Waraga-1 exploration well 13 March 2006 - Hardman Resources, the operator of the Waraga-1 exploration wellin Uganda, in which Tullow Oil Plc (Tullow) is a 50% partner, today issued thefollowing press release. Tullow will provide a further update once loggingoperations have been completed. "Since the last report on 7 March, the Waraga-1 well was drilled from 1,872metres to total depth of 2,010 metres into basement and wireline logs have beenrun. At midnight on 12 March wireline pressure testing and sampling programmehad been completed. Oil samples have been recovered from the 32 metre grossinterval previously reported (at a depth of approximately 1,700 metres).Preliminary indications are that this is a light oil of approximately 40o APIgravity. While no oil water contact was observed, pressure data from the oilinterval and deeper water bearing sands suggests a minimum 45 metre oil columnfor this reservoir interval. Wireline logs and shows while drilling have indicated a deeper, separate zone ofinterest from approximately 1,780 metres to 1,930 metres which contains a numberof thinner sands. Oil samples have been recovered from a sand at 1,893 metres.Pressure testing and sampling has been conducted, with interpretation of resultsexpected in the coming days to determine the extent of this deeper oil bearinginterval and whether it represents one or a number of oil columns. The well will now be cased and suspended ready for future testing. Planning ofthat testing programme is underway and equipment is being sourced and mobilised. Waraga-1 is located 19 kilometres to the northeast of the recently drilledMputa-1 oil discovery well and 41 kilometres southwest of the Butiaba Waki-1well (drilled in 1938). Waraga-1 testing a structural prospect with identicalgeological targets to the oil bearing reservoirs seen at Mputa-1. The Waragaprospect was defined by the 2005 onshore seismic survey and the geological riskwas significantly reduced by the success of Mputa-1."
