OVERVEIW

AGR's Well Management was assigned to evaluate the best option between the different Mobile Drilling Unit (MODU) types. The drilling campaign in focus was to take place in a water-depth that was within the capabilities of both a jack-up and a semi-submersible.

The choice of which MODU was best suited given the weather conditions and the variance in costs was complex and AGR’s client needed a simple presentation of the best solution.

THE CHALLENGE

  • Long lead-time before the start of the campaign and a very variable rig rate
  • Differing weather conditions depending on the time of year the operation would take place
  • Very different impacts of the weather on the operations’ capabilities of each different type of MODU.

WHAT VALUE DID iQx BRING TO THE CLIENT?

  • Using P1 and probabilistic modelling, the two options including the risk and cost outcomes, were reviewed with a clear basis for the decision on which MODU to use
  • The presentation to our client’s partners and management was refined to two slides showing the time and cost
  • A very complex decision that could have resulted in much debate was distilled into an easily understandable choice.

KEY ENABLERS

  • Logical breakdown of operational steps
  • A systematic review of time and cost for the campaign using the different types of MODU
  • An objective review of the risks and range of possible outcomes
