production optimization nowadays is a vital thing to capture for every gas field to get proper production rate. That's they need proper way to optimize there production. Here I have discussed about the process of production optimization using prosper softer from petroleum expert.

4. Objectives
Understand the components of Inflow Performance
Understand the components of vertical lift Performance
Understand combination of Inflow & vertical lift
performance

5. Production Optimization
Production optimization means balance
between production rate/ deliverability
and demand
Production Optimization includes a good
understanding about Production Systems
and Reservoir Fluid.

6. Production Systems
Production Systems includes
Reservoir (Inflow Performance
Relationship)
Wellbore (Completions, Tubing etc.)
Surface Facilities (Flow lines, Separator,
Pipelines etc. )

7. Production Systems
Movement or Transport of reservoir fluid
from reservoir to surface requires energy to
overcome the frictional losses or the
pressure drop.
The pressure drop of the fluid at any time
would be the initial fluid pressure minus the
final fluid pressure
ΔP=Pi - Psep

8. Reservoir Fluid
Phase Behavior
Dry gas / Wet Gas,
Condensate,
Oil,
Water
Fluid Properties
Gas Properties
Liquid Properties
Laboratory Measurements
Composition
Constant Volume Depletion

9. Reservoir Fluid Properties
Properties of the reservoir fluid, like
FVF (Formation Volume Factor), Bo, Bg
Produced Gas/Oil Ratio (GOR) Rp
Solution Gas Oil Ratio, Rs
Compressibilities, Co, Cg
Bubble Point
Gas and Oil Gravities
Densities & Viscosities

10. System Analysis
Reservoir Deliverability System
Well deliverability: determined by a well’s
inflow performance.
The Inflow Performance Relationship (IPR):
the functional relationship between the
production rate and the bottom hole flowing
pressure.
Productivity Index (PI or J): expresses the
ability of a reservoir to deliver fluids to the
wellbore.

11. In Flow Performance Relationship - IPR
Curves
IPR- The relationship between the flow
rate of the well q and the flowing pressure
of the well Pwf.
In single phase flow this is a straight line
At a pressure below the bubble point, this
in not a linear relationship.

12. Tubing Performance (Outflow
Performance)
Tubing performance is the term used to
describe Outflow performance. It is also called
Vertical Lift Performance (VLP).
Need to optimize the Outflow performance
from the bottom of the well to surface
As flow passes through a pipe, the pressure
inside changes. These changes can be
described by three components:
Gravity (hydrostatic)
Friction
Acceleration

13. Tubing Performance (Outflow
Performance)
The outflow system takes energy from the
inflow system and use that energy to get
the total fluid rate to surface
The higher the pressure at the bottom of
the well, the more fluid can be pushed
from the well.

14. Tubing Performance (Outflow
Performance)
Factor Affecting Vertical Lift
Flowing Tubing Pressure
Length of Tubing (Depth)
Friction factors
Tubing Diameter (ID)
Fluid Composition (Liquid / Gas)

15. System Analysis (Combination of Inflow Vs.
Outflow)

16. System Analysis (Combination of Inflow Vs.
Outflow)
Flowing bottom hole pressure (Pwf) = Tubing intake pressure(Pwf e)

18. Production Optimization Using Nodal
Analysis
Well deliverability is determined by the
combination of well inflow
performance and wellbore flow
performance.
This work focuses on prediction of
achievable fluid production rates from
reservoirs with specified production
string characteristics.
The technique of analysis is called
‘‘Nodal analysis’’.
