Hydrostatics and Manometry

Hydrostatics and Manometry

1. Hydrostatics

   • The study of pressures exerted by any fluid at rest.
   • Principle: Pressure increases with increasing depth.
   • Useful Equation
     • F = pgh, where F is hydrostatic force, p is density of fluid, g is gravity and h is height of fluid.
     • F = PA, where F is hydrostatic force, P is pressure, and A is surface are the fluid acts upon.

2. Manometers

   • Piezometer
     • The simplest form of manometer. Not practical to use to measure gas pressure.
   • Differential Manometer
     • Cannot measure but can measure pressure difference.
   • Open Manometer
     • A tube bent into U-shape designed to contain two or more fluids. It is used to measure pressure of different fluids.

3. Industrial Applications

   • Concept of manometry can be used to measure the pressure difference in different wells and production/injection.
   • The pressure difference can be used to find the flow rate/production of oil from a reservoir.
   • Different type of manometry's concepts can be applied in different type of reservoir to achieve optimum production/flow rate.
