Ghana disappoints for Tullow
gHAnA
GROss production from Ghana’s Jubilee eld averaged 88,500 barrels per day (bpd) during the rst half of 2019, Tullow Oil has reported on July 24. TEN owed at 61,500 bpd. Both of these elds produced below expectations, the company said. Jubilee provided 31,400 bpd net to Tullow, while TEN’s net was 29,000 bpd.
Jubilee’s output was below expectations owing to gas compression problems in Febru- ary. Tullow said these had now been resolved. It anticipates full-year gross production to average 96,000 bpd, of which 34,000 bpd will be net. e company has recovered some insurance payouts, though, providing an additional 2,700 bpd of net production equivalent.
At TEN, meanwhile, output was below expec- tations on a delay in completing the Enyenra-10 well in the first quarter. This has now been brought on stream, though there have also been mechanical issues with the completion of the Enyenra-14 well. Completion of this well has been suspended. As a result of these latter issues, Tullow said it was reducing its full-year forecast to around 63,500 bpd at TEN, with a net of 30,000 bpd.
Additional work is underway in the country. Tullow said it had nished 4D seismic on TEN, which will provide more information for future drilling.
Jubilee produced 78,000 bpd in 2018 on aver- age, including 8,600 bpd of production-equiva- lent insurance payments. Output in 2019 from
the eld was forecast at around 96,000 bpd. TEN yielded 64,500 bpd in 2018, and the gure is fore- cast to rise to 83,000 bpd in 2019.
During the rst half, Tullow had two drill- ships – the stena Forth and the Maersk Venturer – working o Ghana. It has drilled four wells and completed three in 2019. e stena Forth le in June to drill a well o shore Guyana. e second rig is completing a well on the Jubilee eld, which is due to start up in August.
Tullow’s vice president for Ghana, Kweku Awotwi, described the rst half as a mixed one for the company. “It is disappointing that we have encountered mechanical issues with a well completion at Enyenra. However, the underlying performance of our Ghana elds remains strong, and I am con dent in the long-term potential of these high-quality assets. Tullow’s non-operated Central and West African portfolio continues to make a solid contribution to Group production, with the portfolio outperforming initial expecta- tions, especially in Gabon.”
Net production from its non-operated elds in Central and West Africa has aver- aged 25,600 bpd, and is expected to rise to an average of 26,000 bpd over the full year. A second phase of drilling will begin on Espoir in the second half of 2019, continuing into 2020. Furthermore, upgrading work on the Okume power and water systems is the focus in Equatorial Guinea, with a workover cam- paign planned for 2020.™
Appraisal Agogo for Angola
AngolA
ENI has drilled a successful appraisal well fol- lowing its Agogo discovery in Block 15/06, it announced on July 25. First production the eld is anticipated this year, with a tieback to the N’Goma vessel, making up the West Hub.
e company said the Agogo-2 well had con- rmed 650mn barrels of oil in place (OIP) in the Agogo eld, with additional resources likely in the north. is will need more appraisal drilling to assess. Data suggest that the well could ow at more than 15,000 barrels per day (bpd).
e well was drilled by the Poseidon drillship, 3km north-west of the Agogo-1 discovery. is is situated around 180km from the coast and 23km from the N’Goma hub, where a oating production, storage and o oading (FPsO) unit is moored. e well was drilled in water depths of 1,700 metres, reaching a total depth of 3,949 metres.
e Agogo-2 found 58 net metres of light oil, at 31 degrees API, in Miocene and Oligocene age sandstones. e statement said this con rmed
the Agogo extension, including below the salt diapirs. e well was highly deviated – and was planned as such – in order to test the areas below the salt.
Eni is the operator of Block 15/06 with a 36.8421% stake, while sonangol P&P has a sim- ilar stake. e remaining 26.3158% stake is held by ssI Fi een. While plans are for production to begin owing this year, the company will con- tinue its work to assess the eld’s full size.
In May, the company announced the Ndungu discovery on Block 15/06, estimating this con- tained around 250mn barrels of light oil. e following month, it said it had made a h nd in a year on the block, with the Agidigbo-1 NFW nding around 300-400mn barrels of light oil in place. ese ve discoveries were estimated to hold up to 1.8bn barrels of light oil.
e Italian company has equity production of around 150,000 barrels of oil equivalent per day (boepd) from Angola. Two hubs, East and West, are producing around 155,000 bpd of oil.™
