We worked with Total E&P Norge AS to optimize the Martin Linge project in the North Sea. We incorporated BlackStream™ along-string measurement (ASM) tools to acquire temperature, annular pressure, rotation, and three-axis vibration data at high frequencies from sensors embedded throughout the drillstring at regular intervals. These measurements were streamed to the surface in real time via the IntelliServ™ high-speed wired drill pipe telemetry network.
Combining ASM tools with wired pipe and high-speed telemetry allowed Total to overcome the limits of hydraulics modeling. Accurately analyzing and understanding wellbore conditions at the bit and in areas such as the casing shoe was critical, while streaming visualization of downhole data optimized hole-cleaning monitoring, reduced nonproductive time, enhanced wellbore control, and sustained wellbore integrity.
These improvements allowed safe increases in ROP and drilling of an additional 1,000 ft of reservoir—saving the drilling cost of one less well while still reaching planned production levels.
