Pressure Calculations

1 / 15

The mud above a 500-foot long cement plug is displaced with a brine.
Mud below the plug = 11.5 ppg
Top of cement plug = 7500 ft
Brine = 8.6 ppg
What is the pressure differential across the cement plug?

2 / 15

Considering the options below, what would be the most appropriate procedure when tripping back to bottom with a heavy pill in the annulus?

3 / 15

Compared to the pressure loss (friciton) around the BHA, the friction around the drill pipe will be:

4 / 15

After experiencing total losses while drilling, the pumps were stopped and hole filled up to the top with water.
Mud weight = 11 ppg
Brine water weight = 8.6 ppg
Height of water column in the annulus = 250 ft
What is the reduction in bottom hole pressure?

5 / 15

What is the definition of Permeability?

6 / 15

What is the definition of Porosity?

7 / 15

What is the pressure gradient of a 12.2 ppg fluid?

8 / 15

Using the information below, answer the following question.

Well TVD = 10 000 ft
Well MD = 12 000 ft
Shoe TVD/MD = 7500 ft
MW = 10 ppg
Drill String Pressure Loss (friction) = 2000 psi
Annular Pressure Loss (friction) = 500 psi
What is the ECD at the bottom of the well?

9 / 15

What happens to bottom hole pressure (BHP) when the pumps are stopped on conventional drilling?

10 / 15

What is the well condition?
MW = 12.2 ppg
Well TVD / MD = 12000 ft / 13000 ft
Formation Pressure = 10,000 psi

11 / 15

Calculate the hydrostatic pressure of an 12.3 ppg fluid at 8000 ft MD (6200 ft TVD)?

12 / 15

Use the information below to answer the following question:

Formation Pressure = 8500 psi at 12000′ TVD /14000′ MD
MW = 12.2 ppg
Drill String Pressure Loss = 2200 psi
Annular Pressure Loss = 550 psi
How much pressure is needed to balance the well against the formation during a connection?

13 / 15

Use the information below to answer the following question:

Drilling ahead at 9000 ft TVD / 10 000 ft MD
Formation Pressure = 5500 psi
Mud Weight = 11.5 ppg
Drill String Pressure Loss = 2000 psi
Annular Pressure Loss = 500 psi

What is the well condition?

14 / 15

Use the information below to answer the following question:

500-foot long cement plug
Mud above the plug = 8.6 ppg
Top of cement plug = 9500 ft TVD
Formation pressure below the plug = 5460 psi

If the plug fails and the bottom of the well is exposed to the atmosphere, what would happen downhole?

15 / 15

What is happens to the Annular Pressure Loss (APL) if the pump rate is reduced from 40 SPM to 30 SPM while pumping a kick out through the vertical section of the well?
