• BlackBox/BlackStream 5-in. EMS Tool

    NOV’s 5-in. BlackBox™ and BlackStream™ enhanced measurement system (EMS) tools record high-frequency measurements downhole and along the drillstring for analysis and optimization of drilling practices. These measurements include downhole weight, torque, two-axis bending, rotation, three-axis vibration, annular pressure, internal pressure, and temperature at a continuous rate of 800Hz. This statistical data (max, min, mean, standard deviation) is recorded to memory every 2.56 seconds. Tools may be run in memory (BlackBox) or “real time” (BlackStream) via the IntelliServ™ wired drillpipe network, and as part of the DDS eVolve™ Optimization Service tiers, and are available in a variety of sizes and materials to satisfy individual project requirements.
