Modular formation dynamics tester
Accurately measure real-time reservoir pressure and permeability and collect high-quality, representative fluid samples.
Forecasting subsurface geothermal energy extraction capability requires knowledge of in situ stresses and fracture breakdown pressure. To acquire this data, SLB uses the MDT modular formation dynamics tester for downhole stress testing. Faced with high-pressure fracturing requirements on one Northeastern US project, SLB introduced its new high-pressure dual-packer system, rated to 10,000-psi differential pressure.
