Tullow: No Commercial Oil at Zaedyus-2 Well (French Guiana)

Tullow Oil plc (Tullow) announces that the Zaedyus-2 appraisal well (GM-ES-2), offshore French Guiana, has completed drilling. The well, drilled 5km up-dip from the Zaedyus-1 well, encountered a total of 85 metres of reservoir quality sands with oil shows in several objectives but did not encounter commercial hydrocarbons at this location.

Results of drilling, logging and sampling to date have shown that the reservoirs at this location are not in communication with Zaedyus-1. Integration of information obtained from the two wells with the 3D seismic data suggests the reservoirs are geologically separated from Zaedyus-1.

As Zaedyus-2 is up-dip and disconnected from Zaedyus-1, this result has no bearing on the bulk of the undrilled prospectivity which is located downdip of Zaedyus-1. Future drilling on the Zaedyus fan system should therefore target the significant upside in the Zaedyus down-dip prospects and the down-dip elements of Zaedyus Deep.

The Zaedyus-2 well was drilled in the Guyane Maritime licence using the Stena DrillMax Dynamically Positioned Drillship. The well was drilled in water depths of 1,894 metres and has been drilled to a depth of 6,200 metres and logging operations are ongoing. The second well in this four-well programme is Priodontes-1, targeting an adjacent prospect within the same Cingulata fan system, and is expected to commence drilling in early December.

Tullow has a 27.5% stake in the Guyane Maritime licence and is partnered by Shell, who are operator and hold a 45% stake, Total (25%) and Northpet (2.5%), a company owned 50% by Northern Petroleum plc and 50% by Wessex Exploration plc.

Angus McCoss, Exploration Director, commented today:  “While the Zaedyus-2 well has not proved an up-dip extension of the Zaedyus discovery towards the apex of the fan, the well has provided very valuable data for the exploration and appraisal strategy of the Cingulata fan system going forward. The French Guiana block remains highly prospective, particularly down-dip and still offer excellent potential for multiple exploration successes. These early lessons learned by the joint venture are being incorporated into our ongoing well campaign.”

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.


French Guiana: Shell to Begin Guyane Drilling in Mid 2012


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.”


ANCAP Reveals Ronda Uruguay II Winners


Uruguay’s state-owned petroleum company, ANCAP, received 19 offers for offshore oil exploration and production on 8 of the 15 offered blocks. Nine oil companies submitted bids from the eleven oil companies initially qualified for the bidding process.

The eight blocks cover more than 50% of the total offered area and they will be placed for exploration works by the four new players in the Uruguayan offshore: the British companies BP and BG, the French company Total and the Irish company Tullow Oil.

After the assessment of the proposals and the approval by the Uruguayan government ANCAP will sign the contracts with the winning companies on September 2012 as a deadline.

There will be a relevant increasing in quantity and quality of the geological knowledge of the offshore basins, as the work plans represent as a whole: one exploratory well at ultra-deep waters, 33.240 km2 of 3D seismic data, 13.080 km2 de 3D electromagnetic data, 130 samples of sea bed, and 3.000 km of 2D seismic data for the first three years of exploration work.

The ANCAP president Raul Sendic highlighted that “the outcomes of the Round imply relevant investments by the oil companies, and therefore there will be significant advances in knowledge and technology, as well as the development of a new services sector”.

The Industry, Mining and Energy Minister Roberto Kreimerman underlined that “Uruguay has a national energy policy that promotes the development of local resources, and ANCAP is a leader in that process. This successful Round also demonstrates that the Uruguay has technical and human expertise and that the world is recognizing the good image of our country”.

The integration of this new 4 top level oil companies to Petrobras, YPF and GALP means the definitive insertion of Uruguay in the world oil map. The winning companies will assume all the risks and costs generated by the oil operations during the phases of exploration and production. The contract is classified as shared production agreement, and under this format the companies are benefited with part of the available production according to the percentages established by the contract. The term of the contract shall be 30 years, and ANCAP may extend the term up to a maximum of 10 years.

The exploratory period comprises a basic sub-period of 3 years, where the companies will execute the compromised exploratory program. There are two voluntary sub periods that involves the production of one exploratory well each, and the last request to return to Uruguay at least the 30% of the area.

ANCAP will have the option for buying totally or partially oil production of the companies if it is needed for the national oil consumption of Uruguay. ANCAP may be associated for the exploitation of each productive block by a percentage offered by each winning company.

Tullow Finds Additional Pay in Enyenra Field
Mar 16, 2012 – Tullow Oil has successfully appraised the Enyenra-4A well in the Deepwater Tano License offshore Ghana. The well encountered oil in very good quality sandstone reservoirs. The company said that good evidence of communication with the Owo-1 discovery wells and the Enyenra appraisal wells confirm the extent of the Enyenra light oil field. Enyenra-4A, located 4.5 miles (7 kilometers) south west of Enyenra-2A and almost 13 miles (21 kilometers) south of the Enyenra-3A well, was drilled to define the southern extent of the field. Results of drilling, wireline logs, samples of reservoir fluids and pressure data show that Enyenra-4A has intersected 105 feet (32 meters) of net oil pay. Pressure data from the oil leg has demonstrated that the oil is in static communication with the oil seen in the other wells in the field, indicating a continuous oil column of approximately 1,970 feet (600 meters). The well will be suspended for later use. The Ocean Olympia (UDW drillship) drilled the well to a total depth of 13,695 feet (4,174 meters) in a water depth of 6,160 feet (1,878 meters).

Anadarko Finds Hydrocarbons Offshore Sierra Leone


Anadarko’s Jupiter-1 exploration well in Block SL-07B-11 offshore Sierra Leone has encountered hydrocarbons. This has been confirmed by the results of drilling, wireline logs and samples of reservoir fluids.

The well, located over 25 kilometres west of the Mercury-1 well which discovered oil in the block, intersected 30 metres of hydrocarbon pay in the primary Upper Cretaceousobjective and did not encounter a hydrocarbon water contact. The well has been preserved for possible future re-entry, as the area is likely to require additional evaluation.

Jupiter-1 was drilled by the Transocean Discoverer Spirit drillship to a total depth of 6,465 metres in a water depth of 2,199 metres. On completion of operations, the drillship will move 15km northeast to the Mercury-2 well which will target several reservoir levels including extensions of the oil accumulations discovered by the Mercury-1 well.

Anadarko (55%) is Operator of offshore Block SL-07B-11 along with partners Repsol (25%) and Tullow (20%).

Angus McCoss, Exploration Director of Tullow, commented today:

“Jupiter is the third discovery in the Liberian Basin by Tullow and its Partners and provides further support for the stratigraphic play in the region. The presence of a working petroleum system producing gas and light oil in the basin is encouraging. Our technical teams will continue evaluating prospectivity across our significant regional acreage position. We will further test the play through the drilling of Mercury-2 in Sierra Leone and Kosrou-1 which is currently drilling in Côte d’Ivoire.”
