Scope first. Price second. Engagement third.

Starting inputs
One agreed asset, the review period and the permitted, accessible records.

Work performed
Match asset identifiers across records, preserve source dates, reconcile reported facts and expose missing or conflicting evidence.

Example of the work
A lease production total and a well record refer to different reporting units. The review makes that distinction explicit before the total is attributed to a well.

Handoff to your team
Use the reviewed evidence register in your asset file and assign the unresolved records requests to your research team.

Starting inputs
One agreed asset, one accepted research question, source coverage and a defined period.

Work performed
Build the relevant comparisons and calculations, examine supporting and conflicting records, and explain what the evidence can and cannot answer.

Example of the work
How did reported gas change between two defined six-month periods? Separate total-volume change from daily-average change and distinguish reported production from available fuel.

Handoff to your team
Attach the findings and their supporting evidence to your existing research review; retain the unanswered questions alongside the conclusion.

Starting inputs
The agreed asset dossier, sources and periods, plus any accepted research questions and deliverable sections.

Work performed
Integrate identity, dated records and analysis; reconcile cross-source conflicts; connect findings to their evidence and unresolved dependencies.

Example of the work
Production history, a permit record and a gas analysis cover different subjects or dates. The dossier shows which findings remain supported and which require new evidence.

Handoff to your team
Give the receiving team one versioned dossier that preserves source references, open dependencies and the reasoning behind each finding.
