Technical Limit
Technical Limit Concept
Implementation
This is the phase where our Performance Engineers begin to perform tactical tasks of implementing the well program from a performance standpoint. They work side-by-side with the rig leadership as well as rig crew and service company personnel. They begin to actively promote a continuous improvement and performance culture and embedding the DPAMS planning, performing, measuring and learning ethos. The phase consists of 4 iterative steps as follows:
...PLAN-PERFORM-MEASURE-IMPROVE
PLAN
Planning meetings are held prior to commencing each phase of the well with participation from all involved contractors. Final program (output) from the
Challenge workshop & lessons learned register is the input to these meetings.
PERFORM
This is the step where the next 12 hours of operations is reviewed and lessons learned are revisited as well as any opportunity to improve the efficiency of the planned activities discussed. Look-ahead actions and target are set for the activity to be performed.
MEASURE
This is a critical step where actual versus planned performance for activities in the previous phase are being recorded, analysed and tracked for further benchmarking and reporting. Performance metrics are posted daily and shared with rig personnel. Variance logs are developed to compare actual, technical limit, AFE & BIC performance to facilitate further performance variance analysis and identify improvement opportunities. Input indicators for agreed key success factors are managed and reported according to agreed communication plan. This is typically in form of a value report published by the rigsite Performance Engineers, where among others; the quantified benefit of the process is reported and shared with the drilling team leadership.
Examples of metrics tracked and reported
- Non productive time (NPT)
- Invisible lost time (ILT)
- Feet/meters per day
- Days per 10K
- Flat time
- Rig moves
- Realized value of “lessons learned”
- Cost under AFE
- Time under AFE
- Riser running speed
- BOP test times
