Completion strings RIH analysis service description

Being deterministic in analyzing the possibility of setting a completion as per plan before running in hole raises multiple problems. The major one is assessing if the completion design is fit for purpose to maximize the well recovery.

Considering the cost of a complex well, a misplacement of the completion due to incapacity to run it in hole as expected can represent a serious decrease in the yield of a well and a significant loss for the operator.

Lock-up is often due to excessive friction between the completion and the borehole. It is usually caused by excessive buckling or/and high wellbore tortuosity. Although basics torque and drag (T&D) calculations are nowadays becoming common practice to anticipate such situations, it appears not to be sufficient in complex wells where 3D tortuous horizontal drains follow the reservoir sequence along dozens of hundred meters. Therefore, both wellbore tortuosity and buckling should be correctly calculated to provide a confident analysis of the potential risk of completion lock-up.

Pre-WellReal TimePost-Well
  • Maximum BPD

    Ensure maximum BPD and early financial break-even point by allowing the completion string to reach TD undamaged.

  • Avoid deferred production

    Avoid deferred production due to challenging operating conditions by optimising completion string design.

  • Completion string deployment

    Anticipate challenging completion string deployment and take appropriate measure by re-design and CWOP.

  • Fishing operations

    Avoid costly fishing operations or in worst case losing the drain.
