Question

1) While drilling a well, a kick was detected at 10100 ft depth, the driller immediately closed in the well and recorded following data was data:

Hole diameter = 8 1/2 inch

Mud weight = 13.2 ppg

Shut in drill pipe pressure (SIDPP) = 530 psi

Shut in casing pressure (SICP) = 800 psi

Pit gain =14 bbls

Assuming that the slow pump rate @30 SPM = 360 psi and the

Annular pressure loss (APL) = 210 psi

Calculate each of the following:

i. Dynamic hole pressure (DHP)

ii. Killing mud weight (KMW)

iii. Equivalent circulating density (ECD)

iv. Maximum allowable annular surface pressure(MAASP)

2- Calculate the volume and density of a fluid composed of 50 lbm of bentonite, 100 lbm of barite, 0.2 gallon of additives and 2 bbl of fresh water.

3- For laboratory purposes, it is desired to mix one liter of bentonite-fresh water mud having a solid content is 3%.

i. Calculate the resulting mud density.

ii. How much of each material should be used? ​
