HOUSTON -- Halliburton has developed a downhole power unit (DPU) series with real time monitoring capabilities for exploration of unconventional assets.

TheIntelligent series permits increased setting and retrieving force and enables readings at higher temperatures and pressures than previous technologies.

"With a conventional downhole power unit, operators have no way of determining the success or accuracy of their work until the entire cycle has been run," says Jim Hill, Halliburton's Wireline Cased-Hole Services product manager. "OurIntelligent series uses real time monitoring and two-way telemetry to verify project status as it happens, greatly increasing the speed and efficiency of downhole service.

Hill adds, "The constant stream of data provided can be checked at any time in order to verify project quality and progress, giving operators a sense of reassurance and confidence that existing tools cannot provide."

The technology was designed to handle higher levels of force with the ability to hold up twice as many foot pounds as legacy tools. This permits setting and retrieving machinery in the well more easily and with a greater degree of reliability in extreme downhole conditions, Halliburton says.

Suited for deepwater drilling sites, the technology can handle 30,000 psi and temperatures up to 400° F with a flask, allowing offshore drillers to accomplish tasks in environments previously considered inoperable.

Halliburton claims its enhancements make the series more robust and user friendly than conventional tools, requiring less hands-on maintenance than predecessors. When a second downhole run is required, users don't have to disassemble and clean the unit, nor are they required to reset the device's intricate settings—everything can be quickly and effectively managed from a computer.
