Wirelessly obtain real-time bottomhole gauge data while controlling nonisothermal effects
Using the modular Symphony testing string united by the bidirectional communication of Muzic Aeon telemetry, PTTEP retrieved accurate, real-time critical downhole data.
The design consisted of a permanent packer and Symphony testing Measure wireless quartz gauges below the packer to obtain pressure transient analysis, minimize nonisothermal temperature effects, and eliminate gauge movement during the test. With real-time bottomhole gauge data, PTTEP evaluated well productivity as it happened. This helped to reconstruct the flow rate history for quick interpretation and fill in gaps when the separator was bypassed.
Implement hydraulic pressure commands in heavyweight mud
Insensitive to pressure fluctuations and mud debris, the Symphony testing Control wireless dual valve provided independent dual-valve operation using wireless commands and the hydrostatic pressure in the annulus. In conventional downhole testing, these commands are typically dependent on the rig pump and annulus fluid transmissibility, a major concern due to the heavy mud density used. The Control wireless dual valve, however, is fully operable in heavyweight mud because of its fast and reliable wireless telemetry commands and can be rapidly adjusted for both anticipated and unexpected operational maneuvers. The real-time bottomhole pressure (BHP) measurements enabled quickly understanding the impact of pressure transmissibility in the heavyweight mud. Engineers were able to recalculate the necessary pressure to apply at surface to rupture the disc of each DST tool and assess the status of each tool.
