Fluid Properties

Fluid Properties

1. Capillary Action

   • Definition: Fluid flowing through porous material or tubes using surface tension..
     • Figure 1: Fluid flowing through porous material
     • Figure 2: Fluid flowing through tubes
   • In Petroleum Engineering: Seen mostly when extracting oil from reservoir using pipes!
     • Figure 3: Fluid Moving up well.

2. Density, ρ

   • Definition: How much of an object is present in given amount of volume.
     • Figure 4: Density of Everyday Materials
     • Figure 5: George McFly being honest.
   • Equation to Use: ρ=mass/volume
     • Units: lbs/cf OR g/cc

3. Surface Tension

   • Definition: fluid property that allows fluid to fight external forces
   • In Petroleum Engineering: Helps find hard it will be to extract oil from reservoir rock
   • γ=Force/Length
     • Units: N/m OR Lbf/ft
   • Fifure 6: Insects can walk on water because of surface tension
