FLUID PROPERTIES
- PHASE
- any homogenous (all liquid,
solid or gas) part of system
separated from other parts
by definite boundary surface
- eg: ice water: 2 phase (l+g)
- PHASE BEHAVIOR
- P-T diagram
- describe phase behavior (equilibria)
betw. phases as changes P,V,T of system
- single component
- SUBLIMATION
curve (s-g), VAPOR
PRESS curve (l-g)
- CRITICAL POINT
- critical temp
- at higher temp than critical temp,
incr. press will not liquefy gas
- at higher temp than critical temp,
incr. press will not liquefy gas
- critical press
- at higher press than criticalpress,
incr. temp can't coexist gas & liquid
- at higher press than criticalpress,
incr. temp can't coexist gas & liquid
- critical temp
- TRIPLE POINT
- temp, press which liquid, solid, gas
coexist under equilibrium condition
- temp, press which liquid, solid, gas
coexist under equilibrium condition
- SUBLIMATION
curve (s-g), VAPOR
PRESS curve (l-g)
- two-component
- BUBBLE POINT curve: down first bubble gas formed
- DEW POINT curve: up
first liquid drop form
- CRITICAL POINT: bubble point & dew
point curves meet, all properties of
liquid & gas are identical
- CRICONDENBAR: max. press on curves, above always liquid
- CRICONDENTHERM: max.temp on curves, always gas
- QUALITY line: temp & press for equal V of liquids, show ratio liquid:gas
- BUBBLE POINT curve: down first bubble gas formed
- describe phase behavior (equilibria)
betw. phases as changes P,V,T of system
- conditions of
temp & Press for
which different
phase exist
- Subcooled/compressed liquid: liquid phase
that has pressure higher than vapour
pressure (above vapour press curve)
- Superheated Vapor: gas phase
that has higher temp than vapor
temp (below vapor press curve)
- P-T diagram
- any homogenous (all liquid,
solid or gas) part of system
separated from other parts
by definite boundary surface
- PURE SUBSTANCES
- uniform&invariable in
chemical composition
- can exist in >1 phase
but each phase must
have same chemical
composition
- eg: ice water is a pure substance with 2 phases
- uniform&invariable in
chemical composition
- SYSTEM: what we want to study
- CLOSED SYSTEM
- no mass loss
from system
- no mass loss
from system
- ISOLATED SYSTEM
- no energy lose
from system
- no energy lose
from system
- system
condition
described
by its
properties
- eg: condtion STATE described by p,V, T
- eg: condtion STATE described by p,V, T
- CLOSED SYSTEM
- SURROUNDINGS: everything external to system
- BOUNDARY: separate system from surroundings
- PHYSICAL PROPERTIES
- INTENSIVE
- independent of quantity of material presented (p,Temp,press)
- independent of quantity of material presented (p,Temp,press)
- EXTENSIVE
- dependent of quantity of material presented (V, mass)
- dependent of quantity of material presented (V, mass)
- INTENSIVE
- COMPOSITION
- C-4:$$$, C-7: cheap
- C-4:$$$, C-7: cheap
- RESERVOIR FLUID TYPES
- decide factors: sampling,
prediction, calculation,
recovery method,
type/size equipment,
depletion plan
- confirmed by:
lab observations,
production info
- determined by fluid
properties: initial
production GOR, gravity &
colour of stock-tank fluid
- Oil reservoir
- reservoir temp < critical temp
- UNDERSATURATED: can dissolve more gas, > bubble-point press
- SATURATED: can't dissolve more gas, =bubble point press
- GAS-CAP/2-PHASE: <bubble point press
- HEAVY oil (BLACK)
- equally spaced quality line, brown/dark green
- equally spaced quality line, brown/dark green
- Light oil ( VOLATILE)
- closer-wider down quality line, green/orange
- closer-wider down quality line, green/orange
- reservoir temp < critical temp
- Gas reservoir
- reservoir temp > critical temp
- RETROGRADE CONDENSATE gas
- closer-wider right quality line, >gas as press
decr, white/colour liquid in stock-tank
- closer-wider right quality line, >gas as press
decr, white/colour liquid in stock-tank
- WET gas
- white liquid in stock-tank
- white liquid in stock-tank
- DRY gas
- only gas in tank/ water
- only gas in tank/ water
- reservoir temp > critical temp
- decide factors: sampling,
prediction, calculation,
recovery method,
type/size equipment,
depletion plan
- decr. temp& press -
decr. VISCOSITIES fluid
- COMPRESSIBILITY
- decr. press - compress effect
gas cap, compaction drive
- decr. press - compress effect
gas cap, compaction drive
