| INVESTMENT THESIS · Let’s build the New Refinery and capture the value.Guyana’s first billion barrels prove upstream scale — not downstream capture. A phased Guyana–Suriname Basin (GSB) conversion platform, anchored by a 30,000 b/d modular refinery in Suriname and expandable to a coordinated 80,000 b/d system, can generate US$1.9–7.6 bn of net downstream value added between 2027 and 2050 before capital, financing and tax, and can drive a recurring US$433–770 m/year BPM6 current-account swing for Suriname (base US$583 m/year; 10-year NPV ≈ US$3.91 bn). GLIAG’s Rev27 bankable base case reports 18.2% equity IRR, US$412 m NPV @ 10%, minimum DSCR 4.95×, and a Brent-US$45 stress DSCR of 1.63× across 120 scenarios. The window is finite, the feedstock is now sanctioned, and the sovereign case is documented. It is time to build. |
The four questions this essay answers
| Question | One-line answer | |
| WHY | Why build a New Modular Refinery now? | One billion barrels are gone, ~8.8 bn remain to 2050, and the sovereign is still importing product. |
| HOW | How is it made bankable? | Four-tier feedstock, GCAA transfer price at Brent−US$2, IFC-PS ESIA, PIMA governance, phased CAPEX, contracted offtake. |
| WHEN | When does the window open and close? | Sanction now; FEED 2026–2027; FID 2027; first product 2030 to catch the plateau; last high-margin decade 2035–2045. |
| WHERE | Where does the plant belong? | 220 ha along the Suriname River in Paramaribo — deep-water access, brownfield services, national security anchor. |
1 · WHY — one billion barrels have left; the next 8.8 billion define the window
On 14 August 2026 ExxonMobil Guyana President Alistair Routledge stated that Guyana “may already have surpassed a billion barrels of production” since first oil in December 2019, against a 6.6-million-acre Stabroek gross recoverable resource of roughly 11 bn boe (Kaieteur News, 14 Aug 2026; Rio Times, 14 Aug 2026; ExxonMobil, Apr 2022 update). None of it was refined domestically. Every barrel exported at crude value is a barrel that will not be converted at product value — and the political consequence has now been named at head-of-state level: on 19 March 2026 President Ali called a refinery a “critical national security priority” (DPI Guyana), and on 26 August 2026 he sketched a national oil company “built around a domestic refinery and expanded fuel-storage capacity” (OGGN, 3 Sep 2026). Suriname is next.
A bankable narrative separates three things a credit committee will not conflate:
• Gross product sales — headline turnover; scale framing only.
• Gross conversion spread — product realisation minus crude and freight, before variable OPEX.
• Net downstream value added (NDVA) — sustainable margin after variable refining and maintenance, before CAPEX, finance and tax. This is the only line that supports NPV / IRR / DSCR.
The historical counterfactual (barrels × 90% utilisation × elapsed days × US$4 / 8 / 12 NDVA) is an opportunity-cost benchmark — not an audited national loss. It is calibrated in line with EIB Economic Appraisal practice (EIB, 2nd Ed., March 2023).
| Measure | Low ($4) | Base ($8) | High ($12) | Meaning |
| 1 bn-bbl full-volume exposure | US$4.0 bn | US$8.0 bn | US$12.0 bn | Ceiling; ignores capacity/demand |
| 1 × 30 kb/d, 90%, Dec-2019 → Aug-2026 | US$0.263 bn | US$0.526 bn | US$0.789 bn | 65.7 m-bbl counterfactual |
| 2 × 30 kb/d, same period | US$0.526 bn | US$1.051 bn | US$1.577 bn | 131.4 m-bbl counterfactual |
2 · The prize — six linked value pools, not one refining margin
A coordinated GSB conversion platform captures six linked pools, which together shift the case from a stand-alone refining margin bet into a sovereign-grade energy-security and macro-stability programme — the frame DFIs and the IMF actually finance:
• Import substitution & FX retention — the primary macro case, measurable in BPM6 current-account terms.
• Refining margin — where product netbacks exceed crude, freight and OPEX under contracted offtake.
• Storage, strategic stocks, blending, terminalling, trading, bunkering — security and optionality.
• Asphalt, lubricants, sulfur handling and selected petrochemicals — high-margin downstream extensions.
• Gas-to-power and shared utilities — competitive industrial energy on domestic gas (Sloanea / Block 52 from ~2030).
• Skills, maintenance, fabrication and supply-chain localisation — the local-content / just-transition layer.
| SOVEREIGN MACRO SIGNAL · US$583 m/year (base) BPM6 current-account swingGLIAG’s published Suriname BPM6 scenario estimates a recurring annual current-account swing of US$433–770 m from import substitution and a modest export tail, base US$583 m, with a 10-year NPV of ≈ US$3.91 bn — against the roughly US$660 m 2023 eurobond stock. This is sovereign economics, distinct from project EBITDA and lender debt capacity, and must never be added directly to project cash flow. Documented, source-anchored, and reconcilable with CBvS customs data, refinery yields, product prices, freight, inventory and binding offtake. |
3 · HOW — the bankable architecture, gate by gate
The New Modular Refinery is not a hope. It is engineered to pass six lender gates that map directly to IMF PIMA infrastructure-governance practice (IMF, PIMA Handbook, 15 institutions), EIB Economic Appraisal (EIB, 2023) and IFC Performance Standards 1–8 (IFC, in force):
| Gate | Bankable evidence | Failure test |
| Feedstock | Assays, entitlement, formula, reliability, blending cases (four-tier portfolio). | No sizing from headline production. |
| Market | Demand, specs, import parity, export netbacks, binding offtake. | No assumed regional sales. |
| Engineering | Pre-FEED / FEED, yields, utilities, emissions, uptime. | “Modular” is not process design. |
| Capital | CAPEX/OPEX, contingency, EPC and completion support (Compass International benchmarks). | No FID on screening estimates. |
| Finance | DCF, DSCR/LLCR, FX, WC, covenants, downside — Brent stress to US$45. | No debt sizing from headline IRR. |
| Sovereign | BPM6, tax, jobs, security, guarantees, contingent liabilities — PIMA-aligned. | No hidden public risk. |
3.1 Four-tier feedstock architecture — the end of single-point risk
Under the Block 58 PSC, Staatsolie has a state right to acquire a defined participating share of the sanctioned development (Staatsolie / TotalEnergies, 1 Oct 2024). The state’s sovereign entitlement — not “Staatsolie crude” — anchors the base case:
• Tier 1 — GranMorgu sovereign entitlement (state participating share, first oil 2028; > 750 m bbl recoverable; 220 kb/d FPSO).
• Tier 2 — Probable Block 52 oil-hub entitlement (Petronas / ExxonMobil / Staatsolie, subject to FID).
• Tier 3 — Negotiated TotalEnergies / APA contractor barrels under a Government Crude Allocation Agreement (GCAA).
• Tier 4 — Optional Stabroek imports / forward discoveries — pure upside optionality.
• Fuel-gas underlay — SAC-1 gas from ~2030 cuts OPEX and Scope 1/2 intensity, strengthening ESIA and IFC PS 3 (resource efficiency).
3.2 GCAA transfer price — the single most important commercial lever
Rev27 recommends Scenario B2 (Brent minus US$2/bbl quality adjustment) as the bankable base, delivering ~US$104.8 m EBITDA and DSCR 3.06× at Brent US$70. Scenario C (pure tolling) is deliberately disclosed as a failure case at DSCR 0.71×. The GCAA architecture is what turns a screening study into a lender-defensible base case.
| Scenario | Transfer basis | EBITDA (Brent $70) | DSCR | Verdict |
| A | Brent flat | Model-linked | Model-linked | Reference |
| B1 | Brent − US$1 quality adj. | Model-linked | Model-linked | Acceptable |
| B2 | Brent − US$2 quality adj. | US$104.8 m | 3.06× | BANKABLE BASE |
| C | Pure tolling fee | Sub-covenant | 0.71× | REJECT (disclosed) |
3.3 Screening returns — proprietary, disclosed, to be superseded at FEED
• Equity IRR: 18.2% · NPV @ 10%: US$412 m
• Minimum DSCR: 4.95× · Brent US$45 stress DSCR: 1.63× across 120 scenarios
• Indicative CAPEX: ~US$550 m for 30–50 kb/d modular configuration (Compass International benchmarks)
• These are GLIAG screening / Pre-FS outputs — not a feasibility opinion — to be audited and superseded at FEED.
4 · WHEN — the window opens now and closes with the plateau
The Guyana–Suriname production plateau opens through 2029–2034 and declines thereafter. GranMorgu first oil in 2028 is the anchor sanction event that turns Suriname from prospective to producing. A New Modular Refinery reaching first product by 2030 catches the plateau; a delay beyond 2032–2033 means catching the decline. Every year of drift shifts the economics from a plateau-margin case to a tail-margin case.
| Milestone | Target date | Purpose |
| Sponsor decision & PMC appointment | Q4 2026 | Mandate GLIAG (or comparable) as Owner’s Engineer / Development Lead. |
| Pre-FEED Readiness Package | Q1 2027 | 12–15 pp positioning, integrated Gantt, stage-gate, FEED financing plan. |
| FEED launch | Q2 2027 | Site-specific engineering; ESIA scoping under IFC PS; HAZID / HAZOP. |
| DFI mandate letters & ITE review | H2 2027 | DFC, IDB Invest, WBG, IFC, FMO, Afreximbank, EIB — reliance letters. |
| FID | Q4 2027 – Q1 2028 | Financial close; EPC award; long-lead procurement. |
| Construction & commissioning | 2028 – 2029 | 24–30 months modular build in parallel with GranMorgu ramp-up. |
| First product (Phase 1, 30 kb/d) | H2 2030 | Import substitution begins; BPM6 swing starts to accrue. |
| Phase 2 expansion decision | 2033 | Trigger on utilisation, offtake, margin bands and Basin depletion. |
| High-margin operating decade | 2035 – 2045 | Debt paid down inside the plateau; equity uplift crystallises. |
5 · WHERE — 220 hectares along the Suriname River in Paramaribo
The site is not incidental — it is the second bankability lever after feedstock. GLIAG’s designated New Modular Refinery site is a 220-hectare parcel along the Suriname River in Paramaribo, chosen for:
• Deep-water river access compatible with modular EPC delivery and product-tanker loading.
• Brownfield service ecosystem — Staatsolie operations, port logistics, workforce, utilities, and existing HSE infrastructure.
• Proximity to national demand — Paramaribo as the primary domestic offtake node reduces distribution cost and captures import-parity margin.
• Land-use headroom for Phase 2 expansion, storage, blending, terminalling and downstream extensions without renewed permitting risk.
• Sovereign security anchor — a strategic asset located inside the national capital footprint and directly accountable to the state.
6 · Why prior refinery studies said no — and why this one says yes
The 2017 Haas / Hartree study (Government of Guyana, May 2017; Stabroek News, 18 May 2017) tested a 100 kb/d FCC greenfield refinery at ~US$5.2 bn CAPEX against then-domestic demand of only 13–14 kb/d, and rightly found it uneconomic. That result was correct — for that configuration, at that scale, at that time. The 2026 case is materially different:
| Dimension | 2017 Haas case | 2026 GLIAG case |
| Scale | 100 kb/d FCC greenfield | 30 kb/d modular, phased to 60–80 kb/d |
| CAPEX | ~US$5.2 bn | ~US$550 m Phase 1 (Compass Int’l benchmarks) |
| Domestic demand | 13–14 kb/d | Growing GSB demand + regional export optionality |
| Feedstock | Speculative | Sanctioned (GranMorgu FID 1 Oct 2024) + four-tier portfolio |
| Fuel | Fuel-oil economics | Domestic gas from ~2030 (SAC-1 / Sloanea) |
| Political frame | Commercial only | National security priority (Ali, 19 Mar 2026) |
| Governance | Pre-PIMA | IMF PIMA-aligned + IFC PS 1–8 + EIB Economic Appraisal |
| Financing | Unstructured | DFC / IDB Invest / WBG / IFC / FMO / Afreximbank / EIB syndicate architecture |
7 · DFI eligibility, safeguards and just-transition posture
Refinery financing is not automatically excluded from DFI mandates, but is screened hard against energy-transition, Paris-alignment and controversial-activities lists. The New Modular Refinery is deliberately positioned as:
• An energy-security asset for a small open economy at Moody’s Ba3 / equivalent sovereign rating (CBvS confirmations, 2025–2026), reducing exposure to imported-product volatility.
• A BPM6 current-account stabiliser directly relevant to IMF Article IV surveillance and IMF PIMA.
• A phased, right-sized platform (start ≤ 30 kb/d) with a domestic-gas synergy from 2030 that materially reduces Scope 1/2 intensity relative to fuel-oil-fired benchmarks.
• A full IFC PS 1–8 scope for ESIA, labour, resource efficiency, community, land, biodiversity, indigenous peoples and cultural heritage, sized for lender ESAP.
• A DFC-aligned developmental case — additionality, private-sector mobilisation, transparency — suitable for U.S. DFC political-risk and debt instruments.
• An EIB Economic Appraisal-compliant economic rate of return with shadow-price and distributional analysis (EIB, 2nd Ed., March 2023).
8 · Indicative capital stack (Phase 1, screening)
| Tranche | Instrument | Indicative provider(s) | Purpose |
| Senior debt | Long-tenor USD facility | DFC, IDB Invest, WBG/IFC, EIB, FMO, Afreximbank | Base project debt |
| Political-risk cover | PRI / MIGA-style wrap | MIGA, DFC insurance | Sovereign / expropriation cover |
| ECA-supported tranche | Buyer/supplier credit | SACE, Euler Hermes, EKF, K-Sure (EPC-linked) | EPC financing |
| Sovereign / SPV equity | Common equity | Government of Suriname or state SPV (anchor sponsor) | Alignment & governance |
| Strategic equity | Common / preferred | Strategic sponsor / offtaker | Feedstock & offtake alignment |
| Contingent equity | Standby facility | Sponsors + syndicate | Completion support |
All tranches to be sized in the Dynamic Financial Model (Component 3 of the 5-Pack), stressed to Brent US$45, and cross-checked against DSCR ≥ 1.30× minimum and LLCR ≥ 1.40× lender covenants.
9 · The GLIAG intelligence stack — how we falsify our own case
The Guyana Basin Production–Depletion & Fiscal Revenue Outlook (Graph GG-2026-028-GSB, Rev003) defines the timing envelope. GLIAG studies translate depletion into sovereign value and industrial sequencing; GLIAG and Guyana Basin Watch newsletters continuously update — or falsify — the model:
• Who Carries the Basin After the Peak? — Stabroek depletion, GranMorgu, Suriname’s plateau-extension window.
• A New Modular Refinery for Suriname — SH-2050 conversion platform.
• Transforming Suriname: From Value Leakage to Capture.
• Why Gas-to-Shore Infrastructure and a New Refinery Are Key to GSB Development.
• Why Projections and Reality Must Be Separated in Suriname.
• Impact of Suriname’s New Modular Refinery; Invest in Suriname: A Self-Funding Modular Refinery.
10 · The proprietary GLIAG Refinery 5-Pack — commercial offer
The GLIAG New Refinery Study and complete bankability package are commercially available for acquisition, licensing or commissioned adaptation for Guyana, Suriname or a coordinated GSB platform. The 5-Pack is a lender-defensible, cross-consistent, KPI-anchored dossier engineered so that a credit committee, a sovereign counter-party, a DFI screening desk and an IMF Article IV team read the same numbers and reach the same conclusions:
| # | Component | What it delivers | Primary reader |
| 1 | Terms of Reference (TOR) | Scope, sponsor, feedstock, market, engineering, capital, finance and sovereign gates; acceptance criteria; ESIA / HAZID / HAZOP scope; governance and COI controls. | Sponsor · PMC · DFI screening |
| 2 | Refinery Feasibility Study for Bankability (ReFSB) | Pre-FS synthesis: assays, yields, product balances, delivered-cost stack, import-parity and export-netback logic, CAPEX/OPEX phasing. | Sponsor board · DFI credit |
| 3 | Dynamic Financial Model | DCF, DSCR/LLCR, tax, WACC, GCAA transfer-price scenarios (A/B1/B2/C), Brent stress to US$45, 120-scenario sensitivity grid, BPM6 macro overlay. | Credit committee · IMF |
| 4 | Bankable Investors Deck | SRN → EN → NL narrative, DFC / IDB Invest / World Bank Group front matter, dashboard CTA, credit-committee appendix, one-page executive brief. | Banks · DFIs · ECAs · sponsors |
| 5 | Executive Investment One-Pager | Deal-in-a-page: thesis, KPIs, DSCR band, BPM6 swing, ask, use of proceeds, next-step gate. | Ministers · CEOs · chairs |
The 5-Pack is proprietary GLIAG intellectual property, produced under a strict source-anchored workflow: every external figure is dated and URL-sourced, unavailable data is labelled rather than estimated, and cross-document KPI consistency (TOR ↔ ReFSB ↔ Model ↔ Deck ↔ One-Pager) is audited before release.

11 · Strategic conclusion — let’s build it
A barrel does not become valuable because it is counted. It becomes valuable when it can be produced, transported, sold — and converted into protected cash.
The first billion barrels have established upstream credibility; the next ~8.8 bn through 2050 create a finite conversion window.
At base sensitivity, 30 kb/d can retain ~US$1.9 bn; 60 kb/d ~US$3.8 bn; a coordinated 80 kb/d Guyana–Suriname system ~US$5.0 bn — before capital, finance and tax, and on top of a recurring ~US$583 m/year BPM6 current-account swing for the sovereign.
The bankable answer is the smallest phased system that contracts demand, survives margin and CAPEX stress, protects sovereign balance sheets, satisfies IFC PS and IMF PIMA discipline, and earns the right to expand. GLIAG has built that answer.
It is time to build the New Refinery — and capture the value.

14 · Methodology, falsification and legal notice
All values are nominal US dollars. Barrels processed = capacity × 90% utilisation × elapsed days; NDVA = barrels × US$4 / 8 / 12 (low / base / high). The GIP path is a GLIAG scenario constrained by stated discovered resource — not a reserves audit, not operator guidance, and not a securities-grade forecast. Reject or revise the results if current demand, assays, yields, netbacks, utilisation, CAPEX, schedule, finance, tax, ESIA or binding offtake do not support them. Sovereign BPM6 estimates must never be added to project cash flow. This essay is not investment advice, a securities offer, a reserve certification, a feasibility opinion, or a commitment by any government, sponsor or lender.
