Tube
Wave Home (Real-Time Completion Monitoring) by Andrey Bakulin Tube or Stoneley waves are used in the oil and gas industry for variety of purposes. Mud-pulse telemetry uses low frequency tube waves to transmit the downhole information to the wellhead. Similarly remote activation of the downhole valves can be triggered with tube-wave pulses sent from the wellhead. Hydraulic Impedance Testing uses low-frequency tube waves send from the platform to observe opening of hydraulic fractures in real time. In open boreholes, permeability estimation from Stoneley is the only direct logging method to evaluate near-wellbore mobility (ratio of permeability to viscosity). In cased boreholes tube-wave reflection logs can estimate quality of the hydraulic fracturing behind casing if measurement is conducted before and after treatment. We extended use of tube wave further to complex deepwater wells (completed production boreholes with sand-screened completion) with the objective of measuring changes in completion permeability during production. We called new technique as Real-Time Completion Monitoring with acoustic waves.
