The work behind the tools.

Four engagements that shaped the suite — from a deepwater entry decision to a risked exploration portfolio, a bid-round development concept and a deep gas screening. Each one was run, or re-run, through the same engines you can install.

A note on confidentiality. Most of this work sits under NDA. Blocks, counterparties and precise figures are anonymised or rounded here; the full walkthroughs — data, decisions, numbers — happen in person, under yours.

Angola — Deepwater entry

Setting
Deepwater acreage offered under Angolan production-sharing terms, with a farm-in decision to be taken against a negotiation clock.
Ask
Screen the entry: what the fiscal terms actually leave the contractor month by month, where the value breaks, and which entry structure survives the downside.
Approach
Development profiles built in Maturatio, run through Estimatio's monthly PSC ledger — cost oil, profit-oil slabs, PIT, decommissioning — under deepwater and marginal-field presets. Two-driver scenario matrices crossed price against schedule; farm-down structures and financing were compared head to head; portfolio sequencing kept the entry self-funding.
Handover
A valuation pack with every scenario re-runnable: the client's team can move any lever — working interest, phasing, fiscal preset — and watch the ledger and NPV respond.

Andaman SeaExploration portfolio & maturationBiogenic gas

Andaman Sea — biogenic gas portfolio

Setting
An exploration and appraisal campaign chasing biogenic gas, with amplitude support to be treated as evidence — not as an answer.
Ask
Turn the interpretation into a portfolio the drilling sequence can be defended on: every closure found, every prospect risked the same way.
Approach
Principal-geoscientist engagement building a ranked, risked prospect inventory with automated workflows; risking ran on a systematic criteria matrix including DHI and fault-seal analysis — the discipline that later became Præsagio's exhaustive trap sweep and Punctio's editable POS matrix.
Handover
A ranked and risked portfolio of roughly 3 Tcf of biogenic gas potential, with the risking criteria on the table so the ranking can be challenged line by line.

Malaysia Bid Round — conceptual FDP and economics AI agents

Setting
A bid round with more blocks than evaluation weeks: each candidate needs a development concept and an economic case, at a tempo manual workflows don't survive.
Ask
Screen the round without thinning the work — a real concept and a real fiscal run per block, not a spreadsheet shortcut.
Approach
AI agents drove Maturatio and Estimatio through the engine API: for each block, agents swept development concepts — well count, phasing, plateau — and pushed every survivor through the Malaysian fiscal terms with sensitivities. Geoscientists reviewed the concepts; the agents did the running, not the deciding.
Handover
Per-block screening packs — concept, profile, fiscal case, tornado — plus the agent harness itself, so the next round starts from software rather than from scratch.

Middle EastDeep gas portfolioPermo-Triassic carbonates

Middle East — Khuff deep gas portfolio

Setting
Deep gas potential in Khuff and equivalent Permo-Triassic platform carbonates, sitting beneath producing horizons — known plays, expensive wells, unforgiving economics.
Ask
Build the deep portfolio: which structures hold gas at Khuff level, what each is worth risked, and which ones justify a deep well.
Approach
Regional carbonate grounding from years on Abu Dhabi subsurface and Khuff-equivalent outcrop analogues fed structural trap mapping in Præsagio, portfolio-consistent risking in Punctio, and gas cases in Maturatio and Estimatio — expansion run from reservoir to plant intake, abandonment pressure back-calculated, deep-well cost against a monthly gas ledger.
Handover
A ranked deep gas portfolio with the same contract everywhere: outlines, risked volumes and a fiscal case per structure, comparable across the whole inventory.

Where the tools come from

Two decades operator-side, distilled into software.

Every engine in the suite encodes a workflow that was first run the hard way — inside Shell, on ADNOC's fields, across independent operators from Oman to Papua New Guinea. The reps below are why the defaults are sensible and the edge cases are already handled.

Raffik Lazar — Principal Geoscientist. Shell International E&P 2007–2016 (Netherlands, Oman, Iran, Malaysia); GeomodL International 2016 to date, serving ADNOC, Turkish Petroleum and independents across the Middle East, Africa and Asia-Pacific; principal contributor at The Dubai Dataroom on spotlight technical-commercial reports and farm-in datarooms.
