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 Bajaโ1 โ discoveryโ.
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 (1723โ1790), 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 readโฆjust 786 pagesโฆ
(โฆwalked swiftly through it, though, as was requested for the International Economics, Executive MBA module, long ago.
While Smith did not use the exact term โeconomies of scale,โ 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, โ International Economics – Theory and Policy โ.
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 2025โฆ

By acquiring nearby reserves, TotalEnergies enhances GranMorguโs scale, extends plateau production, and lowers costs.
While Moeve pivots fully into low-carbon leadership.
1. Background โ Moeveโs Strategic Pivot
In late June 2025, Moeve (the former Cepsa) sold its 25โฏ% stake in Surinameโs Blockโฏ53, which includes the Bajaโ1 discovery, to TotalEnergies ().
This move aligns with their โฌ8โฏbillion โPositive Motionโ strategy, aimed at divesting 70โฏ% of upstream oil and reinvesting in green hydrogen, EV infrastructure, and renewable energy projects.

2. Why TotalEnergies Acted on Bajaโ1
2.1. Infrastructure & Capex Synergies
- Bajaโ1 lies just east of Blockโฏ58โs GranMorgu development, allowing an easy tie-back to the same FPSO, saving ~15โ20โฏ% in Capex per barrel of oil produced ().
- Total’s 220,000โฏbpd FPSO, finalized in Octโฏ2024, was barnโbuilt for exactly this scenarioโsupporting future tieโback resources from adjacent blocks ().
2.2. Reserves & Plateau Extension
The Bajaโ1 field is estimated to add 100โ300 MMbbl to GranMorguโs existing 700โ760โฏMMbbl recoverable resources ().
This volume not only boosts reserves, but sustains plateau productionโoriginally limited to ~4 yearsโby at least 1โ2 additional years.
2.3. ESG & LowโEmission Leverage
- Tieโbacks allow shared infrastructureโparticularly gas reinjection systems and zero-flare setupโenhancing Totalโs low-carbon ambitions (<16โฏkg COโe/boe) ().
- It signals a new frontier model: growth through sustainable integration, not greenfield spending ().
3. Quantitative Impact Summary
| Metric | GranMorgu Only | + Bajaโ1 |
|---|---|---|
| Recoverable Reserves | 700โ760โฏMMbbl | +100โ300โฏMMbbl |
| Plateau Duration | ~4 years | +1โ2 years |
| FPSO Rates | 220,000โฏbpd | Maintained longer |
| Capex Efficiency | Base case | โ15โ20โฏ% per barrel |
| Breakeven Cost | ~$50โ60/bbl | Lowered further |
4. Bigger Picture โ Why This Deal Matters
This move exemplifies modern frontier oil strategy:
- Efficient reserve buildup: Tieโback acquisitions deliver low-risk growth.
- Infrastructure leverage: Shared FPSO uses fixed capacity, cutting costs.
- ESG integration: Zeroโflare, electric FPSO aligns growth with responsibility.
- Frontier dominance: It mirrors Guyana’s basin achievementsโover 11โฏBn barrels discovered ().
5. Conclusion
Moeve sold Bajaโ1 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.
๐ LinkedIn Pitch
๐งญ Why TotalEnergies snagged Bajaโ1: to extend GranMorguโs plateau, cut Capex, and bake ESG into frontier oil growth. For its part, Moeve accelerates its pivot from oil to green power. A textbook moveโsmart capital, smarter energy.
