Production well test analysis (PBU)
Every shut-in on a producer is free reservoir data. We turn planned and opportunistic build-ups into a low-cost surveillance tool — tracking performance, explaining deviations and targeting interventions.

Why it matters
A rate and a pressure don’t define productivity
Because the response is transient, a single rate–pressure pair can’t tell you how a well is really performing — especially vertical wells in low-to-mid permeability, fractured wells and horizontal wells. A build-up can.
- Define initial well and completion performance: skin, permeability, connectivity, initial pressure
- Monitor and forecast well and reservoir performance over time
- Detect performance deviations early and understand their causes
- Assess the real impact of well interventions
- Quality-control your rate measurements
With the right expertise, every shut-in becomes a data point in your surveillance plan — not just downtime.
What we deliver
From new wells to mature producers
New well delivery
- The case for downhole gauges and planned shut-ins
- Data systems that don’t destroy transient data through “compression”
- Planned shut-ins designed for maximum information in minimum time
Ongoing surveillance
- Damage, effective kh, perforated height and horizontal flowing length
- Fracture half-length and conductivity over time
- Reservoir pressure, connectivity and pressure support
- Multiphase flow analysis
Diagnosing deviations
- Water-front detection and breakthrough anticipation
- Fluid breakout caught before it becomes irreversible
- Blockage, sand fill and other near-wellbore problems
- Data acquisition around interventions — and proof of their impact
