Well Cost Control & Forecasting

Subject to participant requirements

Course overview

The course begins with discussion of the fundamentals of Well Cost Control & Forecasting.

The course refreshes the student in the principles of the well cost improvement cycle.

Starting with an overview of the technical side to well construction and cost, through to the relationship with finance and partners in the well, we then look at the authorisation for expenditure (AFE) process.

We then focus on the importance of cost tracking, how it fits in the finance team's monthly reporting cycle, and how it benefits the well engineering team.

Next we look at the final cost review and post well reconciliation process. Finally we look at how to pull all the disciplines together into the well cost improvement cycle and how this benefits the organisation’s annual budgeting, cost estimation, cost tracking, reconciliations, finance & partner reporting, and overall value adding information to the internal management team.

Learning objectives

  • Learn or refresh the principles behind well cost control and forecasting
  • Learn the link between the process of well design & drilling execution and cost control/forecasting
  • Discuss the practical use of well cost control
  • Learn the methods to ensure accurate cost control
  • Learn to create financial control documents: AFE’s, Cost Trackers, Well Reconciliations
  • Learn how to create the value of work done and apply this to month end reporting and overall project forecasting
  • Use what you learn to improve the overall cost improvement cycle
  • How to report and present this financial information and add value to your organisation

The course is designed for

Well and Drill Engineers involved in well design and drilling projects, as well as Finance Teams & Cost Engineers with an interest in Well Cost Control & Forecasting principles.Also for attendees with little or no experience in Well Cost Control & Forecasting to pick up the principles and run a Cost Tracking Model for very simple to more complex types of wells (batch drilling).

The course pulls all the principles of Well Cost Control & Forecasting together and shows how the role fits into an Oil & Gas Operator’s organisation, and how it adds value for the management.
