Sequential Formation Testing
Halliburton’s sequential formation testing tools gather the quality formation data required to evaluate reservoir potential and plan well completions. All parameters necessary for a successful test –accuracy, adaptability, speed, and reliability— are designed into our test tools.
Our general Sequential Formation Testing Tool (SFTT™) uses a Petroquartz pressure transducer to measures wellbore and formation fluid pressure at any point in the well. The SFTT can also collect representative fluid samples for up to two test depths in one trip.
- Determine reservoir pressure
- Identify gas and oil reservoir boundaries
- Monitor reservoir intercommunication
- Indicate areas of pressure depletion
- Estimate formation permeability
- Determine chemical concentrations and reservoir fluid properties
- Measure flow and shut-in pressures vs. time
The Selective Formation Tester IV (SFT-IV™) precisely measures well bore and formation fluid pressure at any point in the well with the use of a Petroquartz transducer. The tool then transmits the pressure data and its associated measurements to the surface via a Remote Telemetry Unit (RTU) and the DITS Subsurface Telemetry Unit (DSTU).
- Pre-test does not start until operator gives the command, allowing:
- Verification of padset before starting pre-test
- Evaluation of mudcake properties from padset data
- Better response to pressure changes
- Provides improved temperature compensation and pressure measurement accuracy
- Reliable transducer operation – even under harsh borehole conditions
