Written by Marcel Chin-A-Lien – Petroleum & Energy Insights Advisor – 30th June, 2025.

My essays always intend to analyse and focus on the underlying context of publications and their resultant relevant, added-value and to-the-point petroleum and energy insights.

TotalEnergies’ acquisition of a 25% interest in Block53, offshore Suriname, from Moeve, formerly Cepsa, with APA (45% and operator) and Petronas (30%) as partners in the license, in fact indicates purchase and participation in the development of the Baja‑1 “ discovery”.

For TotalEnergies this is not just a transaction, it is a smart, diligent business oriented masterstroke of efficiency and foresight.

Or simply applying economies of scale?

Fast back to the future.

The concept of economies of scale has its roots in the work of Scottish economist Adam Smith (1723–1790), who described the benefits of division of labor and specialization in his 1776 book The Wealth of Nations.

Have you ever ventured to read and study this most interesting, foundational and historical textbook?

Nothing to do?

Please read…just 786 pages…

(…walked swiftly through it, though, as was requested for the International Economics, Executive MBA module, long ago.

https://ia801907.us.archive.org/18/items/WealthOfNationsAdamSmith/Wealth%20of%20Nations_Adam%20Smith.pdf

While Smith did not use the exact term “economies of scale,” he laid the foundation for the idea.

Sure, feel free to accompany it by our most lovely textbook of Paul R. Krugman and Maurice Obstfeld, “ International Economics – Theory and Policy “.

Paul Krugman is an American economist, Nobel laureate, and influential commentator known for his work on international trade and economic geography. 

But.

Near to incomprehensible for the poor neurons and synapses of a simple explorationist.

Each and every page and graph of this cryptic and enigmatic, though very interesting textbook.

Venture to study, understand and apply it on deciphering the non-geologic but economic reasons behind the recent Baja-1, Block 53 farm-in of TotalEnergies?

And of others similar farm-ins that I expect to occur, in this incipient, but rapidly evolving offshore landscape in the GSB.

Such as for monetisation of mutual gas discoveries in Haimara, Guyana and nearby Block 58, Suriname.

Well?

You may also want to apply, the following referenced chapter of Krugman, on all that is now happening on this globe, since January 2025…

By acquiring nearby reserves, TotalEnergies enhances GranMorgu’s scale, extends plateau production, and lowers costs.

While Moeve pivots fully into low-carbon leadership.

1. Background – Moeve’s Strategic Pivot

In late June 2025, Moeve (the former Cepsa) sold its 25 % stake in Suriname’s Block 53, which includes the Baja‑1 discovery, to TotalEnergies ().

This move aligns with their €8 billion “Positive Motion” strategy, aimed at divesting 70 % of upstream oil and reinvesting in green hydrogen, EV infrastructure, and renewable energy projects.

2. Why TotalEnergies Acted on Baja‑1

2.1. Infrastructure & Capex Synergies

• Baja‑1 lies just east of Block 58’s GranMorgu development, allowing an easy tie-back to the same FPSO, saving ~15–20 % in Capex per barrel of oil produced ().
• Total’s 220,000 bpd FPSO, finalized in Oct 2024, was barn‑built for exactly this scenario—supporting future tie‑back resources from adjacent blocks ().

2.2. Reserves & Plateau Extension

The Baja‑1 field is estimated to add 100–300 MMbbl to GranMorgu’s existing 700–760 MMbbl recoverable resources ().

This volume not only boosts reserves, but sustains plateau production—originally limited to ~4 years—by at least 1–2 additional years.

2.3. ESG & Low‑Emission Leverage

• Tie‑backs allow shared infrastructure—particularly gas reinjection systems and zero-flare setup—enhancing Total’s low-carbon ambitions (<16 kg CO₂e/boe) ().
• It signals a new frontier model: growth through sustainable integration, not greenfield spending ().

3. Quantitative Impact Summary

Metric	GranMorgu Only	+ Baja‑1
Recoverable Reserves	700–760 MMbbl	+100–300 MMbbl
Plateau Duration	~4 years	+1–2 years
FPSO Rates	220,000 bpd	Maintained longer
Capex Efficiency	Base case	–15–20 % per barrel
Breakeven Cost	~$50–60/bbl	Lowered further

4. Bigger Picture – Why This Deal Matters

This move exemplifies modern frontier oil strategy:

1. Efficient reserve buildup: Tie‑back acquisitions deliver low-risk growth.
2. Infrastructure leverage: Shared FPSO uses fixed capacity, cutting costs.
3. ESG integration: Zero‑flare, electric FPSO aligns growth with responsibility.
4. Frontier dominance: It mirrors Guyana’s basin achievements—over 11 Bn barrels discovered ().

5. Conclusion

Moeve sold Baja‑1 to free capital and sharpen its transformation focus. Meanwhile, TotalEnergies bought it to turn GranMorgu from a sizable project into a basin-scale, low-carbon cash machine.

The added reserves, plateau extension, and ESG credentials make this both smart and strategic.

📌 LinkedIn Pitch

🧭 Why TotalEnergies snagged Baja‑1: to extend GranMorgu’s plateau, cut Capex, and bake ESG into frontier oil growth. For its part, Moeve accelerates its pivot from oil to green power. A textbook move—smart capital, smarter energy.
