WellWatcher Sapphire

PT gauge

Rated to 10,000 psi [69 MPa]
Rated to 230 degF [110 degC]

Acquire downhole pressure data for production and reservoir analysis

Permanent WellWatcher Sapphire PT gauges are engineered to deliver accurate, stable pressure measurements for long-term reservoir and production monitoring applications, including pressure buildup surveys and intelligent completions in conventional reservoirs.

This gauge is qualified for a 10-year life cycle at maximum pressure and temperature conditions. Performance is validated in a controlled test cell, where drift stability is measured at simulated reservoir pressure and temperature conditions.

Rely on our sealing technology for long life

The WellWatcher Sapphire gauge features a dry-mate connector with two independent seals, including an improved metal-to-metal seal. For incremental reliability improvement in conditions such as sour fluids or below-packer applications, the gauge can be equipped with Intellitite downhole dual-seal dry-mate connectors upon request.

For multiple-gauge applications, a fully welded Y block allows efficient deployment of up to six gauges on a cable.
