Phase 2 of the Baleine Project Boosts Côte d'Ivoire's Gas Volumes

Eni and Petroci announced a major boost in gas volumes from the Baleine upstream project to support power generation in Côte d’Ivoire.

Launched in December 2024 on schedule and with full safety measures, Baleine is the first net-zero upstream project (Scope 1 and 2) in Africa. Phase 2 of the project was aimed at strengthening the country’s energy sector and industrial growth, while also improving energy access.

The 70 MMcf/D of gas produced by the project will be used entirely for domestic energy needs. At the same time, Eni has reached its oil production plateau of 60,000 B/D, tripling the 20,000 B/D achieved during the project's previous phase.

With Phase 3 currently under study, total production is expected to reach 150,000 B/D of oil and 200 MMcf/D of associated gas.

Venture Global Receives Non-FTA Export Authorization From US DOE

TotalEnergies Successfully Restarts Tyra II Project

After being suspended in 2019, TotalEnergies' Tyra II project has been restarted with facilities reaching full technical capacity.

Tyra is Denmark's largest natural gas field, with the ability to produce 5.7 million m3 of gas and 22,000 B/D of condensates at plateau.

In 2019, gas production and deliveries were suspended to allow for the field's redevelopment, which had become necessary due to natural subsidence of the reservoir. The new Tyra produces more efficiently and with 30% lower greenhouse gas emissions than the former facilities.

The continuation of ramp up of production is ongoing.

TotalEnergies operates the field with a 43.2% stake. BlueNord and Nordsøfonden hold 36.8% and 20%, respectively.

Drilling Activities in Cyprus' Exclusive Economic Zone Completed

Exxon and QatarEnergy have completed drilling operations at the Elektra-1 well in Block 5 offshore Cyprus. Well data and preliminary evaluation work indicate the presence of natural gas in noncommercial quantities.

According to the operator’s early assessment, Elektra-1 has yielded encouraging results, confirming the existence of a hydrocarbon system and good-quality reservoirs. The data collected during the drilling operations are being evaluated to determine the consortium’s future plans in Block 5.

The Valaris DS-9 drillship, which carried out the drilling operations, will now move on to conduct exploration drilling at the Pegasus 1 wellsite in Block 10 of the Exclusive Economic Zone.

Chevron's Ballymore Begins Production

Chevron’s Ballymore project in the Gulf of Mexico has began producing.

Ballymore, the latest Chevron project to start up in the in the past year, is located in the Mississippi Canyon area 160 miles southeast of New Orleans in around 6,600 ft of water.

The subsea tieback is expected to produce up to 75,000 B/D through three wells tied back 3 miles to the existing Chevron-operated Blind Faith facility.

“Ballymore, which was completed on time and on budget, brings additional production online without building a new standalone offshore platform. This reduces our development costs and is expected to drive higher returns for shareholders,” said Brent Gros, vice president, Chevron Gulf of America.

Estimated potentially recoverable resources at Ballymore are 150 million BOE over the life of the project. another step toward the company’s goal to produce 300,000 net BOED from the US Gulf by next year.

Chevron is operator of the Ballymore project with 60% working interest. Co-owner TotalEnergies has a 40% working interest.
