Project Framing


Project framing is now used widely as part of E&P project decision quality processes. Dundas has developed a set of workshop tools that can be applied to any project. Our project framing workshops will assist your teams to: 

  • Achieve a shared and current view of the project across all disciplines.
  • Have a clear understanding of the project goals and value drivers.
  • Build work programmes enabling key decisions to be made on time.
  • Understand project risks and opportunities.
  • Develop clear alternative strategies and understand their impact on the business objectives.
  • Clarify the project boundaries.
  • Prioritise and plan stakeholder management

Recent Examples

Dundas has participated in, designed and facilitated a large number of opportunity framing workshops. Here is a selection of recent examples:         

  • Major Oil Terminal Redevelopment Strategy
  • Southern North Sea Gas Evacuation Strategy
  • Business Review to Decide on Operating Model for Gas Asset
  • Carbon Capture and Storage Project Concept Select Studies
  • Subsea tie-back to East Irish Sea NUI
  • Central North Sea subsea tie-back
  • Mature asset life extension project
  • FPSO redevelopment project
  • CO2 flood EOR project

Dundas helps clients who already implement project framing as part of a decision quality process and those that wish to start.

Late Life & Decommissioning


Dundas has established a track record of providing outstanding commercial and technical advisory services in the areas of late life asset management and decommissioning.


Dundas has delivered over 30 late life and decommissioning studies including:

  • Project framing - systematic approach to setting goals, scope and priorities
  • Probabilistic decommissioning cost estimate - delivering real insight on the range of potential cost outcomes, integrating the cost estimate and project risk register in a Monte Carlo simulation
  • Decommissioning securities agreement - expert delivery of net value calculations, origination or independent expert review
  • Late life strategy - integrating discounted cashflow modelling, decision and risk analysis and multi-discipline scenario forecasting to identify maximum value and or minimum cost strategies
  • Contract review - proposing where contract risk is best allocated to deliver optimal contractual performance in the supply chain philosophy
  • Pairwise comparison - systematic comparison of alternatives
  • Other - origination of option selection reports, conducting peer reviews, preparation of peer review guidelines, conducting decision analysis and provision of risk reviews

The theoretical approach to determining cessation of production date and planning decommissioning around that is straightforward. In practice the reality can be complex with constraints such as cash supply imposing boundaries on decision making. Dundas has the experience to advise how to respond.

Drilling Schedule Optimisation

Unlock Value by Optimising Your Drilling Schedule.

Our optimisation and analysis software uses a proprietary genetic algorithm to generate schedules maximising value, production or the addition of proved reserves. In addition, our tools enable operators to catalogue schedules and quantify the business impact of their decisions.


Major EP companies need to create and maintain a drilling schedule for a large number of drill strings. The objective is to maximise value, production or reserves from limited resources of cash and rigs/crews. The task is complicated by the following factors:

  • the data is highly dynamic
  • the data is subject to uncertainty
  • business priorities can change

For any significant activity levels, it is impossible to optimise this manually or by inspection. The Dundas tools contain a powerful proprietary optimisation algorithm developed to handle the complex scheduling problem faced in the operation of regional development programmes. The tool may be used to automatically optimise drilling schedules:

  • Select best projects to be executed
  • Determine best chronological order
  • Comply with all business constraints

The optimiser objective function can be either:

  • Value, or
  • Production build-up, or
  • Proved reserves additions (PRA)


The Dundas schedule optimiser will complement existing schedule planning processes, and currently has the following functionality:

  • automated schedule optimisation using a genetic algorithm;
  • schedule evaluation in terms of NPV, cashflow, expenditure profiles, production build-up profiles and proved reserves addition profiles;
  • cataloguing of manually entered and automatically generated schedules;
  • parametric evaluations to quantify the business impact of key sensitivities – e.g. CAPEX availability, string time performance, rig availability;
  • formatted business reports, showing a digest of schedule information and allowing quantitative comparison of alternative schedules.


Our tools enable compliance with all of your business constraints, e.g.:

  • Earliest possible spud date
  • Latest acceptable end date
  • Project precedence
  • Capital availability per annum
  • Number of rigs per rig category
  • Rig availability windows

Business Case

Optimisation of the scheduling of drilling activities can liberate significant value. For example: accelerating a $100m project by four months at the expense of two $25m projects would yield an NPV gain of $1.2m; avoiding a single day of rig idle-time could save, for example, $400,000. A single improvement in scheduling decisions delivers payback on an optimisation project.
