Acquire high resolution pressure data at the wellhead during DFIT, CALIBR® engineered flowback or during a well test
The SPIDR data acquisition system is a well testing and well surveillance solution that captures high-quality well data at the wellhead during flowing and shut-in, without wellbore intervention. The system features industry-leading quartz technology, same day updates, and expert analysis. Halliburton has proven the SPIDR system on thousands of wells all over the world for nearly 40 years.
For gas wells, Halliburton uses a proprietary modification of the Cullender-Smith routine to convert wellhead pressures to bottom hole pressures. For water production or injection, we use an incompressible-flow model. For accurate conversion to BHP of oil wells, the accuracy varies with the quality of the input data (i.e., rates, pressures, and PVT recombination information). Based on test objectives and well conditions, we can optimize the test procedure to mitigate or eliminate possible sources of error. For multiphase wells, we have developed proprietary correlations that can handle mist, annular mist, bubble, dispersed bubble, and churn flow.
Customers use the SPIDR data acquisition system for pressure-transient testing without the cost and risk of running gauges downhole. Because the SPIDR system is nonintrusive, it can be used to test wells where downhole gauges are impractical, including:
Acquire real-time well data without the need for intervention during frac interaction monitoring.
Improve short and long-term well performance, reduce damage to the completion and formation, and increase production.
