LONDON – Tullow Oil is taking various steps to improve operating efficiency and reliability at the Jubilee FPSO offshore Ghana, the company revealed in its latest results review.
Since the start of the year, maintenance measures to increase gas processing capacity have been successful, and following repairs to the water injection system, this is now operating at its full design capacity.
The company has formed a team to implement further reliability improvements to water injection throughout the course of the year.
Ghana’s Ministry of Energy has approved increased flaring from the Jubilee and TEN fields. A combination of flaring, improved gas processing and well/facility optimization has boosted production, with Jubilee currently delivering more than 90,000 b/d of oil.
At TEN, the partners are re-assessing the Enyenra development plan following a faster than expected decline at the field and a reduction in reserves.
They will concentrate investment in the near term on the Ntomme field, where reserves remain strong with potential for future growth. Both fields are currently producing in line with expectations (around 50,000 b/d gross).
Tullow expects to use the drillship Maersk Venturer on Jubilee and TEN this year. After completing a new production well at Ntomme, the vessel will return to Jubilee to drill and complete a water injector before conducting workovers on a producer and a water injector.
The final phase of the Jubilee FPSO’s turret remediation project is the installation of a catenary anchor leg mooring buoy to assist offloading. In January the buoy reached Ghana and once installation has finished and the system is mechanically operational, commissioning should conclude as scheduled during 2Q.
Offshore Suriname, Tullow expects to drill the Goliathberg-Voltzberg North well in block 47 during 4Q, testing dual targets in the Cretaceous turbidite play in around 1,900 m (6,233 ft) of water.
Over blocks 114 and 119 of Argentina’s offshore Malvinas West basin, a 10,500-sq km (4,054-sq mi) 3D multi-client seismic survey started last December. A further 3D seismic survey should get under way in late 2020 over block 122, the company added.

No real news, big uncertainty due to the lack of news from Tullow. (next drills in late 2020? 20201?)
He said the Coefficient of Success is>30% while drilling usually occurs if above 20-25%. Yes, but if the depth of play is as disappointing as Carapa (3m...) what's the matter?
Are ECO and Total even meeting TLW management? Gil was very vague about potential meeting and outcome. Do Tullow even have a management?
In the last 12 months, I've had positions in Weatherford (WFT), Thomas Cook and Mc Dermott (MDR). All three went bankrupt (chapter 11 for the 2 american companies that used to be heavy weight in their business categories).
I have the bad feeling Tullow falls in the same category. Constant series of bad news, Management not managing anything.
What is the worse that can happen to the shareholders?
We are now seeing a SP of 65-70 as something unreachable, we used to be at 200 not that long ago...
Massive depression on my side. I had positions in AAOG that are even worse...
Oil and Gas seems doomed, even XOM are at the lowest in 10 years... in spite of 16 successful discoveries in Guyana with a total of 8 billion barrels recoverable and a very favorable Production Sharing Agreement...

Karoon Energy Ltd. has executed binding agreements with Stena Drilling and Tullow Oil to contract the drillship Stena Forth.
The Stena Forth will drill the Marina-1 exploration well on block Z-38 offshore Peru. Drilling is expected to start in early 1Q 2020.
Karoon is the operator and holds 40% in block Z-38.
The Marina exploration prospect is a large fault bounded structure in the Tumbes basin with prospective reservoirs at multiple levels from 900 m to 2,900 m (2,952 ft to 9,514 ft) subsea. Gross prospective resources are estimated at 256 MMbbl.

Marina-1 will be the first well drilled on block Z-38. Water depth is about 350 m (1,148 ft). Planned total depth of the well is 3,026 m (9,928 ft).

Total E&P Namibia has awarded Bourbon Marine & Logistics an integrated logistics contract.
The project scope covers provision of logistics base, freight forwarding, custom clearance, material storage and warehousing, handling and lifting, marine port visits support along with tank cleanings and logistics operations planning and conduct (material and personnel).
The company will provide Integrated logistics services through a local branch, Bourbon Logistics Namibia, with a local partner, Logistics Support Services.
The project started in early August 2019 and is expected to last about one year with drilling activities expected in the first semester 2020. The operations will be managed out of Lüderitz, a port in the south of Namibia.

LONDON and TORONTO – Analysis of oil samples taken from the recent Jethro and Joe discovery wells offshore Guyana suggests that both fields contain heavy crudes with a high sulfur content.
Operator Tullow Oil and its partners are assessing the commercial viability, taking into account the quality of the oil and the reservoir sands and strong overpressure.
The wells on the Orinduik license proved two different oil plays in the Cretaceous and Tertiary intervals. Tullow said it retained confidence in the potential of multiple prospects identified in these plays throughout the license and in the non-operated offshore Kanuku blocks.
Both structures were drilled on the far north of the company’s acreage. Tullow continues to update its petroleum system models in pursuit of further prospects and lighter oil in the area.
These, and the result from the Repsol-operated Carapa well on Kanuku, will help shape the planned 2020 drilling campaign.
Orinduik partner Eco (Atlantic) Oil & Gas said the samples from Jethro-1 and Joe-1 indicate mobile heavy crudes, similar to the commercial heavy crudes found in the North Sea, Gulf of Mexico, the Campos basin offshore Brazil, Venezuela, and Angola.
The partners have brought in a heavy oil development consultant to answer their technical queries and to assess various potential development drilling and production scenarios.
Jethro-1’s 8,500-psi (586-bar) reservoir (2,600-psi/179-bar overpressure) has the advantage of natural drive efficiency, Eco said. The high reservoir temperature of 94°C (201°F) and an estimated flowing well head temperature of 90°C (194°F) are both positive in terms of oil mobility and should provide an advantage at the floating production facility, the company added.
Colin Kinley, Eco’s COO, said: “The fact that the oil is already hot in the reservoir, and mobile, and has high quality porous sand to travel through, helps to eliminate a great part of the conventional heavy oil challenge.
“Having 8,500 psi in the porous warm formation is an added advantage to drive the oil to the well. Horizontal well technology can allow excellent access to these thick fields and generally reduces the need for multiple additional wells, leading to lower development cost per barrel.”
