Ophir hits gas with Silenus East-1 well in Equatorial Guinea

Return to news list

16 September 2014

Ophir Energy plc (Ophir) announces that the Silenus East-1 well in Block R, Equatorial Guinea has resulted in a new gas discovery. The Silenus East-1 well was drilled by the Vantage ‘Titanium Explorer’ drillship within the thrust belt area of Block R. A 67m gross gas column was encountered in the primary target with high quality reservoir in line with pre-drill expectations. The well was deepened to test a secondary high risk oil target and encountered high quality, but water-wet, reservoirs with weak oil shows. This play remains of interest to Ophir and will be further evaluated on the Block. The drillship has now moved to complete the Fortuna-2 appraisal well, where Ophir will conduct the first flow test in Block R. The Silenus East-1 well has discovered an estimated mean recoverable 405bcf of gas from the upper and deeper reservoirs and has significantly de-risked a family of similar surrounding prospects such that the total mean recoverable gas in the broader Silenus area including this discovery is now estimated at c.1.2TCF. Following the Silenus East-1 and Tonel North-1 well results, the total estimated mean recoverable resources for Block R, including the discoveries and adjacent derisked volumes, are now 3.4TCF, comprising 1.3TCF from the Fortuna Complex, 1.2TCF from the Silenus Complex, 0.5TCF from Tonel and 0.4TCF from the other smaller discoveries.

Ophir's Tonel North-1 well has poor result

Ophir Energy plc (Ophir) is pleased to provide an update on its operations in Equatorial Guinea. The Tonel North-1 appraisal well has been completed on Block R, Equatorial Guinea. The Tonel North-1 well was drilled approximately 5km north-east of the original Tonel-1 discovery well. The well encountered gas pay combined in the lower target sands but the upper sands appear to be low gas-saturation. Analysis of the well data is ongoing. The result is expected to marginally reduce the discovered volumes in the Tonel field but will not impact the commerciality of the base case 2.5mmtpa FLNG project. The ‘Titanium Explorer’ drillship has now moved to complete the Silenus East-1 exploration well which is targeting ca.420bcf of low-risk mean prospective gas resource as a primary target and will be deepened to test a secondary, high-impact but high-risk oil target that on current mapping could be a potentially extensive play across the Block. The top hole of Silenus has already been previously drilled and the well is expected to complete within two weeks. There are several analogous shallow gas prospects to Silenus East in the Thrust Belt play sharing the same Direct Hydrocarbon Indicators. If successful, the well would de-risk ca.1.2TCF of upside (including Silenus East volumes) in the immediate area that could provide an additional production hub for the FLNG development.

Sputnik-1 well deemed non-commercial by Perenco

Perenco today issued the following operational update for the Arouwe block offshore Gabon. The company announced that the Sputnik-1 well, targeting a pre-salt structure in Gabon’s offshore Arouwe block, has encountered non-commercial hydrocarbon pay in up to 300 metres of net sandstone reservoir. The Vantage’ Tungsten Explorer’ drillship, drilled Sputnik-1 to a final depth of 4,868 metres in water depths of 1,023 metres. The rig will now leave the Arouwe block and the results of this well will be incorporated into wider understanding of the region.”

Ophir completes drill stem test on Fortuna-2

Ophir Energy plc (“Ophir”) has announced the successful Drill Stem Test (DST) on the Fortuna-2 well in Block R, Equatorial Guinea. Ophir holds 80% of Block R and GEPetrol 20%. After successfully drilling and coring the Fortuna-2 well, a DST was conducted to prove the deliverability of the Fortuna gas field. The DST achieved a sustained flowrate of 60MMscfd with a drawdown of less than 20 psi at the reservoir. This rate was surface equipment constrained. Based on the expected operating conditions of the FLNG facility, the well is estimated to have been able to deliver a production rate of c.180MMscfd via the 5” drill pipe that was used for the DST. The excellent flow rate, at minimal drawdown, is a strong indication that the number of development wells required for the Fortuna reservoir will be reduced from the seven initially assumed in scoping work, thereby improving development economics. During pre-FEED, this result will be evaluated, in conjunction with the core, to create reservoir models that will then help determine the final number of development wells. The Fortuna field complex has estimated mean recoverable resources of 1.3TCF and will form the first phase of the FLNG development. This result further de-risks the Miocene turbidite play that forms all of the Block R accumulations. The total estimated mean recoverable resources of Block R, including the discoveries and adjacent de-risked volumes, are now 3.4TCF. The incremental volumes (1.2TCF from the Silenus Complex, 0.5TCF from Tonel and 0.4TCF from other smaller discoveries) will be produced in the later phases of the development as the Fortuna field comes off plateaux. The next milestones for the Block R FLNG development will be (i) the agreement of gas fiscal terms and (ii) the selection of the consortium to build, own and operate the mid-stream project. Both of these are anticipated by end 2014. The award of the upstream and midstream FEED contracts is planned in early 2015. FID is expected in 2016 and first gas in 2019.

Vantage respond to reports surrounding 'Titanium Explorer' contract

Vantage Drilling Company ("Vantage") has challenged reports alleging that the arrest of a former Petrobras International Director was tied in some way to the Company's contract with Petrobras for the Titanium Explorer. "Several hundred contracts were signed by this former Director, which in Vantage's case, was after the parent board of Petrobras had approved the contract," said Paul Bragg, Chairman and CEO of Vantage. Vantage is fully performing under the contract and found no evidence that would substantiate any allegation of improper activity by Vantage in connection with the award of the contract. Paul Bragg additionally commented, "Vantage has always been committed to conducting itself in accordance with the highest standards of business ethics. We do not believe that any inappropriate act was committed by any personnel associated with Vantage. Although we are disappointed that recent news reports have suggested that a former Petrobras International Director was arrested on the suspicion of some form of wrongdoing associated with Vantage, as well as with other companies contracted to Petrobras, we are confident that any suggestion is without merit as it relates to Vantage."

Ophir Energy begins new exploration campaign in Thailand

Ophir Energy Plc (“Ophir”) has announced that it has commenced a two well exploration drilling program in Block G4/50, in the western Gulf of Thailand with the spud of G4/50-10 exploration well on the Soy Siam prospect. The G4/50 Block partly surrounds Ophir’s producing Bualuang oil field and spans a series of Tertiary aged sub-basins in the western Gulf of Thailand. The two well program will test whether there is a working hydrocarbon system in one of these, the presently undrilled South Western Sub-Basin. The main play risk is considered to be charge, specifically source distribution and maturity. The Soy Siam Prospect comprises a single fault block which has potentially been charged from both the Bualuang and South Western Sub-Basins. The G4/50-10 well is targeting Miocene sandstones that are the age equivalent of the producing reservoirs in the Bualuang oil field, located 15 km to the north. The Soy Siam Prospect has 25 MMbo of mean prospective resource and a 21% chance of success. On completion of the G4/50-10 well, the rig will move to drill the Parichat South West (SW) prospect. The Emerald Driller jackup rig is being used for the G4/50 drilling programme. The estimated cost of the two well program is USD18 million and it is expected to take approximately 50 days to complete.

Results of G4/50-10 Exploration Well

Ophir announces that it has completed operations on the G4/50-10 exploration well that was testing the Soy Siam prospect. The well reached a total depth of 1,627 metres (True Vertical Depth Sub-Sea) and encountered the primary Miocene reservoir targets on prognosis in terms of both reservoir quality and depth. However, all reservoirs were dry and no hydrocarbon shows were encountered. The well has therefore been plugged and abandoned as a dry hole. Preliminary well failure analysis suggests that the structure had no access to charge, which was identified pre-drill as one of the key risks. The rig will now move to drill the Parichat South West prospect. This well is independent of Soy Siam as it is testing a different petroleum system. The Parichat complex is a cluster of four fault blocks located 30 km south of the Bualuang field that have potentially been charged from deeper in the South Western Sub-Basin. Each fault block has multiple stacked, Miocene and Oligocene reservoir targets. The South West fault block is the initial target with a mean prospective resource of 25 MMbo and a 32% chance of success. If successful, the Parichat South East fault block would form an immediate follow on location.

Spudding of CAT BA-1X exploration well

Salamander Energy announces the spud of the Cat Ba–1X (“101-CB-1X”) exploration well in Block 101-100/04, offshore northern Vietnam. The 101-CB-1X well will be drilled to a depth of approximately 1,900 metres. The primary objective is a Palaeozoic carbonate, (buried hill) structure with secondary objectives in the overlying Tertiary clastic section. The mean gross pre-drill estimate of prospective recoverable resource is approximately 100 MMbo. The well will be drilled by the Aquamarine Driller jack-up rig in a water depth of 49 metres. It is expected to take approximately 25 days to complete on a dry hole basis. Salamander holds a 30% operated interest in Block 101-100/04, subject to final government approval of the farm-out of 20% interest to JX-Nippon Oil & Gas Exploration Corporation announced in May 2011.

CAT BA-1X sub-commercial oil and gas discovery

Salamander Energy announces the completion of the Cat Ba–1X (“101-CB-1X”) exploration well in Block 101-100/04, offshore northern Vietnam. Block 101-100/04 was the subject of a farm out as announced on 31st May 2011. The 101-CB-1X well was drilled to a total depth of 1,724 metres. The well encountered 38 metres of net hydrocarbon pay in Tertiary clastics, the secondary objective of the well. The pay section comprises a series of gas-bearing sandstones underlain by an oil-bearing reservoir. A full suite of wire-line logs and pressure data were recorded over the reservoir sections and samples of oil and gas were recovered. These data show that the Tertiary reservoirs are of good quality, however pressure data and seismic mapping indicates the in-place resource volumes encountered by the well are probably below levels needed for commercial development. No oil shows were observed and only low levels of gas were recorded while drilling the primary objective, the Palaeozoic ‘buried hills’ play. Subsequent wire-line logging did not reveal any zones of interest. The Cat Ba-1X well has subsequently been plugged and abandoned as a sub-commercial discovery.

'Titanium Explorer' drillship commences drilling of the Padouck-1 exploration well

Ophir Energy plc (“Ophir” or “the Company”) announces that drilling operations have now commenced on the Padouck Deep-1 well on the Ntsina Block, offshore Gabon utilising the Vantage Titanium Explorer drillship. Ophir has a 40%* operated interest in the Block. Padouck Deep-1 is the first well targeting the pre-salt play offshore in the North Gabon basin although the play is regionally extensive elsewhere in Gabon and West Africa. The prospect is estimated to contain Pmean recoverable resources of c.1.0bnbbls with significant follow-on potential. The well is located in a water depth of approximately 835m and has a planned Total Depth of 3,500m True Vertical Depth Sub Sea. Operations are expected to take approximately 45 days. Ophir’s share of the well cost is largely carried by partners Petrobras and OMV.

Ophir comes up dry with Padouck Deep-1 well in Gabon

Ophir Energy plc (“Ophir” or “the Company”) announces that drilling operations have now concluded on the Padouck Deep-1 well in the Ntsina Block offshore Gabon. Ophir has a 50%* net operated interest. The well was drilled by Vantage Drillling's 'Titanium Explorer' drillship to a depth of 3,297m TVDSS targeting the Cretaceous Gamba and Coniquet/Dentale sands in the pre-salt section. Thicker than expected, good quality Gamba and Coniquet/Dentale reservoir sands were encountered. There were no significant hydrocarbon shows in the targeted reservoirs, however, minor shows were interpreted at shallower intervals providing evidence of a working hydrocarbon system in the offshore North Gabon Basin. In addition, well log responses in the deeper pre-salt stratigraphy are similar to those observed onshore Gabon where they are indicative of an interbedded pre-salt source and reservoir system. Full analysis and interpretation of the log data is ongoing. The key pre-drill risk was that of seal and trap integrity. The lack of the anticipated thin salt drape over this high relief prospect and the lack of sealing shales within the targeted reservoirs appear to be a cause of the prospect’s failure. Vantage Drilling's 'Titanium Explorer' will now move to the Gnondo Block to drill the Affanga Deep prospect which has the potential to hold mean recoverable resources of 170mmb and to derisk several follow on prospects which could provide the basis for a hub development. The rig will then return to target the Okala pre-salt prospect on the Mbeli Block.

Ophir releases Affanga Deep-1 well update

The Affanga Deep-1 well being drilled by the Vantage 'Titanium Explorer' drillship is targeting an extension to the proven Ogooué Delta play offshore Gabon with gross mean pre-drill recoverable resource estimates of 170mmbbl. Success would derisk several follow-on prospects which could be integrated into a hub development. The well commenced operations on 22 March 2014 and has a planned Total Depth of approximately 4,500m True Vertical Depth Sub Sea (“TVDSS”). It is expected to take approximately 35 days to complete. Ophir has a 70%* operated interest in the Block. On completion of the well, the rig will move to the Mbeli Block in Gabon to drill the Okala pre-salt prospect.

Affanga disappoints for Ophir in Gabon

Ophir Energy plc (Ophir) announces that drilling operations have now concluded on the Affanga Deep-1 well in the Gnondo Block offshore Gabon. Ophir has a 100%* operated interest in the Block. The well was drilled by Vantage Drilling’s ‘Titanium Explorer’ drillship to a depth of 4,240m TVDSS and was targeting a number of reservoir intervals of Turnonian and Cenomanian age. The well encountered thinner than expected sandstone sections with poor reservoir characteristics. Gas and indications of liquids were encountered during drilling but significant hydrocarbon shows were not encountered in the target formations. Cuttings have confirmed the presence of a Cenomanian oil prone source rock which may have positive implications for the prospectivity of the wider Ogooué Delta outboard play and for the Deepwater play to the west of this location. Log and cuttings analysis is continuing. The rig will now move to spud the pre-salt Okala prospect on the Mbeli Block. The Okala-1 well is expected to take approximately 40 days to complete. *OMV farm-in for a 30% net interest is subject to Government approval

Ophir comes up dry with latest well in Gabon

Ophir Energy plc (Ophir) has announced that drilling operations have now concluded on the Okala-1 well in the Mbeli Block offshore Gabon. Ophir has a 50%* net operated interest. The well was drilled by Vantage Drilling’s ‘Titanium Explorer’ drillship to a depth of 4,229m MD targeting Cretaceous sands in the pre-salt section. The well encountered a thick section of Aptian salt as prognosed and well developed sandstones in the Gamba and Dentale formations. However, there were no significant hydrocarbon shows in the target reservoirs. Ophir’s share of the Okala-1 well costs was partially covered by carries from the Company’s joint venture partners. The ‘Titanium Explorer’ drillship will now move to Equatorial Guinea to begin a campaign of three exploration and appraisal wells on Block R. *OMV farm-in for a 10% net interest is subject to Government approval
