If the well was shut-in while the kill mud was being prepared what would you expect to happen to the drill pipe pressure and to the casing pressure readings?

  1. Outline the considerations when selecting jet bit nozzle sizes

 

  1. Outline the causes of wellbore pressure changes while running in hole and while tripping out of hole (i.e. surge and swab pressures). Why do we need to pay attention to this?

 

  1. Outline the causes of stuck pipe. Discuss the steps you would take to remediate this situation. (about 1page)

 

  1. A 15000 ft (TVD) well was shut-in after taking a kick with a 15 ppg drilling mud in the hole. After the pressures stabilized it was observed that the drill pipe pressure was 780 psi and casing pressure was 1044 psi.

Calculate

  1. The hydrostatic pressure
  2. The shut-in bottom hole pressure
  3. The formation pressure
  4. The required mud weight to kill the well and drill safely

What does the shut-in casing pressure tell you?

If the well was shut-in while the kill mud was being prepared what would you expect to happen to the drill pipe pressure and to the casing pressure readings? Why should these pressures be carefully monitored?
