Flow Performance Study Update for DST Operation

Background
Following a successful flow performance study conducted in 2024, a leadingenergy operator engaged our team to update the analysis in preparation for anupcoming Drill Stem Test (DST) on a CCS appraisal well. The objective was toremove a previous 150-bar wellhead pressure constraint to better assessfracture initiation potential and incorporate a revised well design.
Scope of Work
We proposed a structured and collaborative approach, delivered through four keywork packages:
- Input Data Review
- Flow Performance Modelling
- Tubing Stress Analysis
- Additional Sensitivities and Model Updates
Outcome
The updated study provided a robust, constraint-free evaluation of injectionperformance, supporting DST planning and fracture risk assessment. Byintegrating the new well architecture and sensitivity scenarios, the analysiswas aligned with current operational objectives and subsurface conditions.
