As the amount of dissolved gas increases, the density of the fluid will:

• Increase.

• Decrease.

For the IPR curve, as the bottom hole flowing pressure (Pwf) increases, the flow rate will:

• Increase.

• Decrease

• Still the same.

For the VLP curve, as the bottom hole flowing pressure (Pwf) increases, the flow rate will :

• Increase.

• Decrease

• Still the same.

For a model with PI IPR model, the deviation survey will mainly affect the following calculations:

• IPR

• VLP

• Both

For a closed-in natural flow well, the drawdown is:

• Maximum

• Minimum

• Zero

In the PI model representation of current and future IPRs, which of the following statements are NOT valid (Two Answers):

• IPRs before and after stimulation are the same

• VLPs before and after stimulation are the same

• IPRs before and after stimulation can be represented by two parallel lines.

• The PI model assumes linear, single-phase flow and is only valid for undersaturated reservoirs at pressures well above the bubble point

The intersection of IPR with Y-axis depends on:

• Bottom whole flowing pressure

• Reservoir pressure.

• Permeability.

• Productivity index.

The slope of IPR curve is affected by (select the best answer):

• Bottom hole flowing pressure

• Reservoir pressure.

• Permeability.

• Productivity index

The intersection of IPR with X-axis is affected by (Select the best answer"s"):

• Reservoir pressure.

• Permeability.

• Productivity index.

• Pay zone height

• All answers are right
