Self-powered intelligence

SPIDR® is a well testing and well surveillance solution that captures high-quality well data without wellbore intervention.

Unconventional Well Testing

  • Diagnostic Fracture Injection Testing (DFIT™)
  • Test ultra-low permeability formations in real time for reservoir and formation properties
  • Analysis of the DFIT data can be used to optimize the hydraulic frac design

Accurate Conversion to Downhole Pressures

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.

Nonintrusive, highly effective 

Customers use the SPIDR® system for pressure-transient testing without the cost and risk of running gauges downhole. Because the SPIDR is nonintrusive, it can be used to test wells where downhole gauges are impractical, including: 

  • Highly deviated wells
  • Horizontal wells
  • Wells with tubing restrictions
  • Sour-gas wells
  • High-pressure wells
  • Wells with high bottomhole temperature

Accuracy by design

SPIDR acquires high resolution pressure data at the wellhead during flowing and shut-in, which is then converted to bottomhole conditions. The conversion is accurate for wells that have no standing liquid column. Halliburton has proven the SPIDR system on thousands of wells all over the world for more than 25 years.
