The problem

  • Production forecasts can drift when static models, surveillance data and commercial assumptions are not aligned.
  • Reserve bookings and lender reviews need independent technical rigour, not just internal optimism.
  • Operators often need rapid screening on infill, workover and redevelopment options before committing capital.
  • Reservoir uncertainty becomes harder to manage when subsurface, wells and facilities decisions are made in silos.
  • Asset teams need practical reservoir input that improves decisions now, not just long simulation cycles.

Services consultants offer

Reservoir modelling and surveillance

  • Static and dynamic model review, calibration and history match support
  • Reservoir surveillance interpretation using pressure, rate and production trend data
  • Decline analysis, performance benchmarking and recovery improvement opportunities

Reserves and commercial support

  • Independent reserves and resources reviews for boards, banks and investors
  • Production forecasting to support acquisitions, divestments and development gates
  • Sensitivity analysis across commodity price, well count, uptime and deliverability assumptions

Field development and optimisation

  • Well spacing, drainage strategy and redevelopment planning
  • Reservoir-to-facilities integration for brownfield and greenfield decisions
  • Shortlist studies on infill drilling, workovers, pressure support and late-life recovery

Technical assurance

  • Peer review of models, assumptions and forecast methodologies
  • Decision support for management teams ahead of investment or reserves sign-off
  • Independent technical notes that translate uncertainty into practical actions

Representative outcomes

Forecast reset before investment gate

Independent review of assumptions, uptime and decline behaviour can sharpen development decisions before capital is committed.

Reserves confidence for stakeholders

Technical assurance work helps management, lenders and investors understand uncertainty ranges and booking logic.

Better integration across teams

Reservoir specialists can align subsurface assumptions with wells, facilities and commercial decision-makers earlier in the cycle.

Who our consultants serve

  • Asset Managers needing decision-ready production forecasts and reserves support
  • Subsurface Leads seeking external review of models and redevelopment options
  • Corporate development teams assessing acquisitions, divestments or asset value
  • Field development teams needing reservoir input tied to practical execution choices
  • Boards and investors looking for independent technical confidence

How engagement typically works

  1. Define: confirm asset context, key decisions, timeline and available data
  2. Review: examine models, surveillance, reserves assumptions and forecast methods
  3. Test: run sensitivities on production, recovery, well count and timing
  4. Align: connect subsurface findings with wells, facilities and commercial implications
  5. Deliver: provide clear recommendations, uncertainties and decision-ready outputs
