Esgian's latest market roundup for the fourth week of 2024 brings several updates on new oil discoveries and plans for exploration drilling across the world, together with reports about new contracts and mobilization of rigs.  


Contracts


Dragon Oil and and Bluewhale Offshore have signed a three-year contract extension for the 300-ft jackup Caspian Driller, keeping the rig working for Dragon Oil offshore Turkmenistan. The extension is effective immediately following the conclusion of the rig’s current contract in the first quarter of 2024. Caspian Driller has been working for Dragon Oil for over 10 years.


Drilling Activity and Discoveries


Equinor has discovered oil in exploration well 30/12-3 S in the North Sea off Norway. The well also included a sidetrack well, 30/12-3 A, which was dry. Equinor drilled the well on behalf of Aker BP, which is the operator of production licence 272 B where the wells are located. The licence is part of the Munin field, which was discovered in 2011. The drilling was conducted by Odfjell Drilling’s 10,000-ft semisub Deepsea Stavanger.

Tullow Oil expects to conclude its drilling activity at the Jubilee field offshore Ghana around six months ahead of schedule. The company and its joint venture partners then intend to take a break from drilling in Ghana before resuming in 2025. Tullow Oil has been drilling at its Jubilee and TEN fields offshore Ghana with Noble 12,000-ft drillship Noble Venturer (previously Maersk Venturer) for the past several years.

After more than a year on standby offshore Darwin, Australia, the 8,200-ft semisub Valaris MS-1 has resumed drilling operations at Santos' Barossa development. The rig arrived at the Barossa field in mid-January from its standby location southeast of Cape Fourcroy, Bathurst Island, in the Beagle Gulf.

Santos said that, despite the delays, it still expected the first gas from Barossa in 2025, however, not in the first half of 2025, as originally planned when the FID was made in 2021.

Borr Drilling 400-ft jackup Gunnlod has completed work with SapuraOMV after drilling six development wells at the Jerun field offshore Sarawak, Malaysia. Gunnlod is expected to remain in Malaysia for upcoming work with an undisclosed operator, scheduled to run from around February to May 2024, based on a binding LOA fixed in 2023.

Murphy Oil is advancing plans to drill two exploration wells in the Cuu Long Basin offshore Vietnam in 2024. The wells are expected to be spud in the second half of 2024 with Japan Drilling 425-ft jackup Hakuryu-11.

Occidental Petroleum (Oxy) will drill two exploration wells in the eastern US GOM in 2024, with spud dates targeted for the second quarter of 2024. Oxy plans to drill the Ocotillo well on Mississippi Canyon Block 40 and the Orange well on Mississippi Canyon Block 216. The company called these wells “promising exploration opportunities” in late 2023. Oxy has two drillships under contract in the US GOM; Valaris 12,000-ft unit Valaris DS-16 and Diamond Offshore 10,000-ft unit Ocean Blackhawk

Portuguese oil company Galp said Friday it had discovered a significant column of light oil in reservoir-bearing sands of high quality at AVO-2, a deeper target of the Mopane-1X well, offshore Namibia. Galp is using the Odfjell Drilling-managed semisubmersible Hercules for the operation.

The recent updates on the Sea Lion development progress have included an updated development plan to align with Navitas Petroleum LP' reservoir models, leading to an 11% increase in certified resources across the entire North Falkland Basin portfolio. Navitas has identified suitable and available existing floating production storage and offloading (FPSO) vessels and is actively working with leading industry vendors to secure all long lead equipment, with the goal of reaching the Sea Lion Phase 1 Final Investment Decision (FID) in 2024 and achieving first oil by the end of 2026.

Sonangol and its partners are continuing planning for activity at Blocks B3/05 and B3/05A offshore Angola. Partner Afentra stated that planning is continuing on the selection of the initial phase for electric submersible pump installation, workovers and infill wells at B3/05 and B3/05A. Drilling candidates include the undeveloped Bufalo Nord field, Gazela discovery and an exploration well at Pacassa South West.


Mobilisation/Rig Moves


COSL’s 4,921-ft semisub COSLProspector has left the Canary Islands and is now en route to its final destination, Norway. The semisub is expected to reach Norway in early February 2024. Following preparations, it will start a two-year firm contract with Vår Energi in the Barents Sea in Q3 2024.

The Shelf Drilling-owned 300-ft jackup, Main Pass IV, has recommenced operations with Saudi Aramco in the Middle East. The Main Pass IV performed its planned maintenance at Zamil Shipyard in Saudi Arabia. With the recommencement of this contract, the rig will be busy until March 2025.

Stena Drilling’s 1,640-ft semisub Stena Don is at a yard in Norway where it is undergoing some recertification works related to special periodic survey (SPS)/UWILD. The rig has been under contract with Shell in the UK from May 2023, but the contract has been paused recently for it to undergo these works related to the SPS, which is due on 27 February 2024. Once these operations are completed, the semisub will return to the North Sea.

Valaris 350-ft jackup Valaris 118 has been docked in Chaguaramas, Trinidad for routine maintenance and upgrades ahead of its next six-well campaign with bp. Valaris 118 has been working for bp in Trinidad since October 2022. After the completion of its yard stay, the rig will return to bp offshore Trinidad for a six-well contract extension, fixed in November 2023.

Transocean 1,640-ft semisub Transocean Endurance has left Dampier, Australia, and is being towed to Woodside’s Stybarrow site to start a P&A contract. The rig, which arrived in Australia from Norway earlier this year, has its destination set to Eskdale, a reservoir that is part of the Stybarrow Development, together with the Stybarrow reservoir. The Cat D rig is expected to reach the site on Thursday, 25 January, and upon final acceptance, it should start its contract by the end of the week.
