Surma Basin Block SUR-01

The Surma Basin is part of Bangladesh’s northeastern sedimentary province and is associated with a mature hydrocarbon exploration setting. Subsurface evaluation should pay particular attention to folded structures, fault architecture, reservoir distribution and seal effectiveness. Legacy wells and seismic datasets can provide the starting point for an updated interpretation. Prospect ranking should be based on integrated geological risk rather than structure size alone.

Resource potential is best communicated as prospective potential until block-specific technical work is completed. Volumetrics should be generated from mapped closures, reservoir assumptions, recovery factors and geological chance of success, with uncertainty ranges clearly stated. Historic regional results can inform play concepts but should not be used as a substitute for block-level data. Any commercial resource estimate must be independently reviewed before external publication.

The opportunity may suit an exploration partner seeking exposure to a proven onshore petroleum province while maintaining staged capital discipline. Early activity could focus on data-room access, subsurface re-interpretation, prospect ranking and programme design. Partnership structures can be considered around technical studies, drilling participation or broader local-market support, subject to licence and regulatory conditions.

The investment case should connect subsurface upside with available infrastructure, access conditions and the applicable fiscal framework. Capital can be staged so that the highest-value technical uncertainties are addressed before larger drilling and development commitments. Full economics, risk registers, cost assumptions and transaction structures are reserved for protected diligence materials.

This block is framed as a disciplined exploration proposition within the Surma Basin portfolio. The work programme is intended to move from regional screening to prospect maturation, then to appraisal and development only where technical and commercial evidence supports progression. The project can also be evaluated as part of a multi-block portfolio to share subsurface, operational and market-entry capabilities across northeastern Bangladesh.

Key technical workstreams include seismic interpretation, well-log correlation, petrophysical review, basin modelling, reservoir characterisation and volumetric uncertainty analysis. Where legacy seismic quality limits confidence, targeted reprocessing can be considered before new acquisition. Drilling candidates should be selected only after integrating structural, stratigraphic, charge, reservoir and seal risks into a documented decision framework.
