The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

All rocks in the earth's crust are fractured to some extent. Fractures form in response to stress. The origin of stress can be lithostatic (arising from the weight of the earth's crust), high fluid ...

Engineers have dispelled a 100-year-old scientific law used to describe how fluid flows through rocks. The discovery could lead to a range of improvements including advances in Carbon Capture and ...

Recent advances in flow sensing have resulted in more accurate, durable, and economical meters. Increasingly important is the ability to interface meters with a computer for instantaneous flow readout ...

Under the right conditions, sand can flow. When heavier grains are placed atop lighter grains in a container, the less dense grains can burble upward like the blobs of a lava lamp, a study finds. The ...

Previous chapters have addressed fracture geometry, physical and geomechanical properties of single fractures, fracture detection, and the interpretation of hydraulic and tracer tests. All of these ...
