Chapter 3: Reservoir Deliverability

Question 1

__ is defined as the oil or gas production rate achievable from reservoir at a given bottom-hole pressure. It determines types of completion and artificial lift methods to be used.

Answer 1

Reservoir Deliverability

Question 2

T/F Reservoir deliverability depends on Reservoir Pressure, payzone thickness and permeability, reservoir boundary type and distasnce, wellbore radius, reservoir fluid properties, near-wellbore condition, and reservoir relative permeabilities.

Answer 2

True

Question 3

The analytical relation between bottom-hole pressure and production rate can be formulated for a given flow regime. The relation is called…

Answer 3

Inflow Performance Relationship (IPR)

Question 4

__ is defined as a flow regime where/when the radius of pressure wave propagation from wellbore has not reached any boundaries of the reservoir. It acts like it is an infinitely large reservoir.

Answer 4

Transient Flow

Question 5

___ is defined as a flow regime where the pressure at any point in the reservoir remains constant over time.
This flow condition revails when the pressure funnel has propagated to a constant pressure boundary.

Answer 5

Steady-State Flow

Question 6

____ is defined as a flow regime where the pressure at any given point in the reservoir declines at the same constant rate over time. This flow condition prevails after the pressure funnel has propagated to all no-flow boundaries. A no-flow boundary can be a sealing fault, pinch-out of pay zone, or boundaries of drainage areas of production wells.

Answer 6

Pseudo-Steady-State Flow

Question 7

___ is a graphical presentation of the relation between the flowing bottom-hole pressure and liquid production rate.

Answer 7

IPR Curve

Question 8

The magnitude of the slope of the IPR curve is called the …

Answer 8

Productivity Index (PI or J)
