The objective of the Zaedyus well was to test whether the Jubilee-play, successfully established in West Africa, was mirrored on the other side of the Atlantic. This discovery therefore opens a new hydrocarbon basin within which several neighbouring prospects have been mapped. This result also reduces the exploration risk associated with Tullow's prospect inventory offshore French Guiana, Suriname and Guyana. An appraisal programme and extensive follow-up exploration activities will now be considered.
The Zaedyus well is being drilled in the Guyane Maritime licence using the ENSCO 8503 deepwater semi submersible. The well was drilled in water depths of 2,048 metres and has been drilled to a depth of 5,711 metres. Drilling operations will now continue and the well will be deepened to over 6,000 metres to calibrate the deeper geology. The well will then likely be sidetracked to enable cores to be obtained over the reservoir sections.
Tullow (27.5%) operates the Guyane Maritime license and is partnered by Shell (45%), Total (25%) and Northpet (2.5%), a company owned 50% by Northern Petroleum plc and 50% by Wessex Exploration plc."
Angus McCoss, Tullow's Exploration Director, commented today:
"The discovery at Zaedyus has proved the extension of the Jubilee-play across the Atlantic and made an important new discovery in French Guiana. Tullow has built a commanding and unique acreage position in South America and this result marks the start of a significant and potentially transformational long-term exploration and appraisal campaign in the region."
Derek Musgrove, Managing Director of Northern Petroleum Plc, also commented today:
"This has been and continues to be an adventurous well both in terms of petroleum geology and technical operations challenge in over 2000 metres of water. It has taken some time, but we are beginning to feel that the results are encouraging.
It is a pleasurable experience to be working in an exploration group with Tullow, Shell and Total encountering and overcoming the operational challenges. I trust that we have gained some useful experiences to apply in the future offshore Italy where our interests are greater."
