Shell has started drilling at Cebus prospect (GM-ES-4), the third well of the current four well exploration programme in the Guyane Maritime Permit (French Guiana), Northern Petroleum, which holds a stake in the permit, has announced.
The drilling operations are being conducted with the Stena Ice Max drillship.
Northern through holding 50 per cent of Northpet Investments Limited, owns a net 1.25 per cent interest in the offshore exploration licence ‘Guyane Maritime’. Northern is in partnership with Shell (Operator, holding 45 per cent), Total (25 per cent), Tullow Oil (27.5 per cent) and Wessex Exploration (also holding 1.25 per cent through owning the remaining 50 per cent interest in Northpet Investment Limited).
Keith Bush, Chief Operating Officer of Northern stated:
“This is a new, exciting opportunity for the joint venture to further establish the oil production potential in French Guiana. We look forward to the results of this well with great interest.”
Northern announces that as anticipated by Shell France on June 23rd, The Stena Drillmax ICE drillship commenced operations on the GM-ES-2, the second well on the Guyane Maritime permit on Friday 6th July. GM-ES-2 follows up on the Zaedyus oil discovery in late 2011, which encountered 72 metres of net oil pay in two turbidite sand systems successfully proving that the Jubilee play is mirrored across the Atlantic from West Africa.
The potential of this well was indicated by the Chief Executive of Shell France, Patrick Romeo who stated that, “drilling should last three months and Shell hopes to discover a reserve of at least 300 million barrels of oil” as reported by Dow Jones Newswires. Also, Tullow’s Exploration Director, Angus McCoss was quoted in the New York Times as having said the field could be larger than Jubilee, with 1 billion barrels or more of recoverable oil.
The partner interests in offshore Guyane are:
Shell 45.0% and operator
Northpet Investment 2.5% (Northern owns a 50% equity interest in Northpet Investments)
Derek Musgrove, Managing Director of Northern stated:
“We are pleased to be following up on the highly successful Zaedyus discovery so quickly. Through this project shareholders may benefit from this potentially very high impact event without any great cost exposures. I look forward to updating shareholders on progress.”

Northern Petroleum announces plans to commence drilling in mid 2012 on the Guyane permit offshore French Guiana, to follow up on the Zaedyus oil discovery in late 2011 that demonstrated the prospectivity of this licence area off South America. This is a relatively low cost investment for Northern with high upside potential.
In the Zaedyus exploration well, 72 metres of net oil pay was discovered in two turbidite sand systems in the first phase of drilling – successfully proving that the Jubilee play is mirrored across the Atlantic from West Africa.
The second phase of drilling is planned to involve the spudding of a de-lineation well on the discovery, likely to be followed by an exploration well on one of the neighbouring prospects within the area captured by 3D seismic survey. Additional 3D seismic is also planned to be acquired from midyear to further delineate leads on trend and similar to the Zaedyus discovery mapped on 2D seismic along the length of the deepwater margin.
To undertake these operations Shell, who took over as Operator from Tullow Oil on 1 February 2012, has contracted the Stena DrillMax ICE drillship, which is expected to commence operations midyear subject to government consents.
The partner interests in offshore Guyane are: Shell 45%, Tullow 27.5%, Total 25%, Northpet Investments 2.5% (Northern owns a 50% equity interest in Northpet)
Derek Musgrove, Managing Director of Northern stated:
”Northern is pleased that the successful Zaedyus oil discovery is to be quickly followed by a new drilling campaign. This will not only further delineate the discovery structure, but will also move forward to drill some of the similar prospects defined by 3D seismic in order to confirm the wider significant potential of this permit area covering the entire length of the prospective continental shelf edge of Guyane, a distance of about 200 kilometres.”

Northern announces that earlier today, Tullow Oil Plc (“Tullow”) in their Interim Management Statement provided the following update on well GM-ES-1, in the Guyane Maritime Permit, in which Northern has a 1.25% interest:
“In French Guiana, the Zaedyus exploration well discovered 72 metres of net oil pay in two turbidite fans. This is the first well in Tullow’s extensive Guyana Basin acreage and successfully proved that the Jubilee play is mirrored across the Atlantic from West Africa. Currently, a sidetrack is being drilled to recover reservoir cores with operations expected to complete in mid-November. The partners are working on the 2012 programme and anticipate it to include 3D seismic and the drilling of two wells which is expected to commence in mid-2012 once all the necessary approvals have been obtained.
Shell is expected to take over Operatorship of the block in early 2012, subject to Government and Joint Venture approval.”
