Extended Well Tests
Understand reservoir potential to reduce your risks
Resolve reservoir uncertainty with confidence
Extended well tests (EWTs) are used to evaluate the productivity and characteristics of a reservoir. In particular, EWTs are used to
- estimate reservoir volume and confirm reserves for field development
- confirm long-term reservoir deliverability
- pilot future facility designs during field development
- estimate interwell transmissibility and wellbore storage
- verify static data dynamically
- obtain additional production-related data, such as water cut, sand production, and well deliverability.
You can also use an EWT to test sand control techniques and process- and production-related technologies. By testing early on, you’ll minimize risks related to developing a field for long-term, sustained production.
Reliable solutions to meet your EWT objectives
Our reservoir, completions, production, and facilities engineers team to design fit-for-purpose, regulatory-compliant EWTs that acquire representative surface and downhole data as the basis for your completion and facilities solutions.
Various commercial models are available to suit your needs:
- validation of seismic, geological, and petrophysical data
- reservoir fluid sampling and analysis
- real-time multiphase well testing and monitoring
- sand control and intelligent completions
- provision of sellable products using production facilities or conventional well testing equipment
- production management and engineering.
