Shell Starts Drilling at Cebus Well, Offshore French Guiana

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 Petroleum: More Drilling to Be Conducted Offshore French Guiana

Northern Petroleum Plc  announces the joint venture decision to extend current drilling operations on the Guyane Maritime permit in French Guiana.

The GM-ES-3 exploration well is the second well of a four well exploration drilling campaign that commenced in 2012 to follow up the oil discovery at GM-ES-1 in 2011.

The GM-ES-2 well had exploration objectives in the major Cingulata fan system within which the original oil discovery was made in two ages of formation. GM-ES-3 has been planned to deliver exploration information in the subsidiary Priodontes fan system to the north west of the Zaedyus oil discovery.

The GM-ES-3 well intersected a 50 metres gross section of oil stained sands in the lower part of the Bradypus fan which was not a target formation at this location although it is also within the main Cingulata fan system. A 325 metres gross interval of sandstones was encountered in the targeted Priodontes fan, but these were logged with no significant hydrocarbon shows.

It has been decided by the Shell, Total, Tullow Oil and Northpet Investments Limited joint venture that this well provides a suitable location to drill deeper in a plan to penetrate the full post Atlantic rift sequence. The duration of this additional drilling will depend upon results from the formations encountered.

“This information may prove crucial to a fuller understanding of the exploration potential of this very large licensed area. Although this extension may cause a small delay to the further wells in this exploration programme, the earlier the deeper formations are examined, the better the advantages to be gained from its use in the second part of the drilling programme and aid efforts towards discovering more oil,” said NorthernPetroleum in a press release.

The well is now targeted to reach a final depth of 6438 meters subject to operational factors.

Derek Musgrove, Managing Director of Northern stated: “Following the oil discoveries of GM-ES-1 in 2011, the task before us was to explore the licence to ascertain its wider potential. Whilst the sand package in the primary target proved not to have significant hydrocarbons at this location, the oil staining encountered in the Bradypus fan is encouraging of the broader active hydrocarbon systems and potential.

“Northern supports this fuller exploration approach to this well. It is likely to provide Partners with further geological data imperative to gaining further understanding of the complex geology in this area”

Repsol, Partners Abandon Jaguar-1 Well (Guyana)| Offshore Energy Today

Repsol, Partners Abandon Jaguar-1 Well (Guyana)| Offshore Energy Today

CGX Energy Inc. last week announced, along with its partners on the Jaguar-1 well located on the Company’s 25% owned Georgetown Petroleum Prospecting License (“PPL”), that drilling operations at the Jaguar-1 well on the Georgetown PPL, Guyana ended and the well would be plugged at a depth of 4,876 metres without reaching the primary objective in the Late Cretaceous geologic zone.

The decision to stop drilling at this point was unanimously agreed by all partners based on safety criteria and was taken after reaching a point in the well where the pressure design limits for safe operations prevented further drilling to the main objective.

Jaguar-1 was a high pressure, high temperature (HPHT) well which was spudded in February 2012 using the Atwood Beacon jack-up rig. Whilst the primary Late Cretaceous objective was not reached, samples of light oil were successfully recovered from two Late Cretaceous turbidite sands. The partners to the Georgetown PPL are Repsol Exploración S.A (15%), as operator, along with YPF Guyana Limited (30%), Tullow Oil plc (30%) and CGX Resources Inc. (25%).

Kerry Sully, President and CEO stated, “Based on hydrocarbons recovered during the drilling of Jaguar-1, CGX is confident that a new well targeting the same prospect would hold significant promise and is therefore committed to seek a re-drill utilizing a new well design.”

Commenting on the Company’s plans in the Guyana Suriname basin, Suresh Narine, Chairman, reiterated CGX’s near-term goals stating, “In addition to our commitment well on the Corentyne Block, we are planning a 3D seismic program later this fall with our ultimate goal being to commit to a rig for a three to five well program. Added to this would be the re-drill of the Late Cretaceous target addressed by the Jaguar-1 well.”

Second Well Follows Guyane Oil Discovery

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

Tullow 27.5%

Total 25.0%

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.”

In accordance with the AIM Rules – Guidance for Mining and Oil & Gas Companies, the information contained in this announcement has been reviewed and signed off by the Exploration and Technical Director of Northern, Mr. Graham Heard CGeol.

FGS, who has over 35 years experience as a petroleum geologist. He has compiled, read and approved the technical disclosure in this regulatory announcement. The technical disclosure in this announcement complies with the SPE/WPC standard.

Tullow Oil Abandons Jaguar-1 Well Offshore Guyana

Drilling operations at the Jaguar-1 well in the Georgetown Block, Guyana, have ended and the well will be plugged and abandoned at a depth of 4,876 metres, without reaching the primary objective.

The decision to stop drilling at this point was unanimously agreed by all partners based on safety criteria and was taken after reaching a point in the well where the pressure design limits for safe operations prevented further drilling to the main objective.

Jaguar-1 was a high pressure, high temperature well which was spudded in February 2012 using the Atwood Beacon rig. Whilst the primary Late Cretaceous objective was not reached, samples of light oil were successfully recovered from two Late Cretaceous turbidite sands above the primary objective.
