A project partially funded by the Department of Energy's National Energy Technology Laboratory has created a differential pressure sensor, encased in a 1-inch cell, that may be able to detect, in real-time, slight fluctuations in downhole mud weight, enabling engineers to preempt a sudden surge in pressure or temperature.
