Disclaimer: own musings, independent opinion, insight and vision.
I did this exercise principally for myself, trying to understand and to have a grounded insight in this block and surrounding area.
This nonetheless the fact that only scarce and mainly veiled information is published by official channels.
In case one would venture to obtain an external “ Expert Report “?
One would most certainly have to pay a really fat (some 6 digits) pack of green bucks to get one.
I wish to share it, as well as all my other posts on Guyana Suriname Basin and Switi Sranan, to whow it may interest or serve.
As a tribute to the dear and most beautiful and interesting country of my grandparents, parents, extended family, friends and all others, in Switi Sranan.
Odi odi, tan bun allamala, soso lobi.
Following ExxonMobil’s 2024 exit, Petronas now holds 100% of the offshore Block 52 license in Suriname.
Staatsolie retains a 20% farm-in option, likely to be exercised upon a competitive Final Investment Decision (FID).
A two-well exploration and appraisal campaign, contracted with Noble Corporation for 2025, will critically determine the future of oil and gas development here.
Notably, Petronas benefits from a 10-year tax holiday for gas projects under a newly negotiated gas clause, crucial to project viability.
Block 52’s potential lies in both oil-prone and gas-rich accumulations.
The oil development is planned via FPSO (Floating Production Storage and Offloading), targeting an initial plateau of 100,000 bbl/d from 2030.
Meanwhile, a potential FLNG (Floating LNG) project could monetize 2–3 Tcf of gas starting 2031+, leveraging the tax holiday for economic enhancement.
FYI: See more details on this sub-chapter 3.1 in a companion essay titled “ Block 52 “ Oil Field “ (?), Petronas, Offshore Suriname: Lessons from Liza-1’s Success,
Description: Modeled oil production decline profiles for FPSO in Block 52 (4-year plateau duration: 100,000 bbl/d from 2030):
All scenarios suggest significant depletion and low output by 2055.
Description: Projected gas production decline profiles for FLNG (plateau: 600 MMscf/d from 2031):
Significant production tapering after 25 years impacts late-cycle gas revenues.
Description: Combined annual revenues from FPSO oil and FLNG gas projects:
Total project revenue declines sharply after 2045 as both resources deplete toward zero by 2055.
Description: Key financial metrics per development year:
| Year | Capex (MMUSD) | Opex (MMUSD) | Revenue (MMUSD) | Free Cash Flow (MMUSD) |
|---|---|---|---|---|
| 2030 | 500 | 0 | 0 | -500 |
| 2031 | 400 | 0 | 0 | -400 |
| 2032 | 200 | 50 | 1400 | 1150 |
| 2033 | 100 | 60 | 1350 | 1190 |
| 2034 | 50 | 70 | 1250 | 1130 |
| 2035 | 0 | 80 | 1150 | 1070 |
Positive free cash flows start post-2032 with strong margins until 2040.
Description: Project sensitivity to oil and gas prices:
| Oil Price (USD/bbl) | Gas Price (USD/MMBtu) | NPV (MMUSD) | IRR (%) |
|---|---|---|---|
| 60 | 5 | 500 | 12 |
| 70 | 6 | 800 | 18 |
| 80 | 7 | 1100 | 24 |
Project economics improve significantly with higher commodity prices, particularly oil.
Petronas’ Block 52 offshore Suriname development hinges on successful 2025 drilling outcomes.
Oil via FPSO and gas via FLNG could both technically and economically feasible.
A positive FID will likely attract Staatsolie’s 20% participation.
The 10-year gas tax holiday is pivotal to the FLNG’s long-term viability.
