Thank you so much Abdelaziz , really appreciate your in-depth lectures. I look forward to see all your previous lectures in English version ! All the best
how there is no pressure loss inside the casing ( there is a metal friction force like what happens in any tube the surface of the fluid is not levelled what is called meniscus (all the fluid has a grabbing force inside it and surface area makes the fluid grabbed to the metal surface too due to the chemical interaction and that is the cause of corrosion. s could you let me why it is not calculated inside the annulus between casing and drill pipe?
Hi, I have a question, hope you can help me - apologies if it's too much but I am totally confused! Exercise 1-6: After setting 13-3/8 inch casing, at 8,500 feet, the casing shoe was drilled out and a casing shoe test was run. Leak-off pressure was determined to be 1,100 psi. The test was conducted with a mud density of 12.8 ppg in the hole. Calculate the following: Pressure @ Shoe = _______ psi Gradient @ Shoe = _______ psi/ft (Shall the pressure/depth be used or MW*.052 because the answers are very different) EQMD @ Shoe = _______ ppg Exercise 1-7: After running the leak-off test in the previous exercise, drilling proceeded to 11,000 ft during which time the mud density was increased to 14.4 ppg. Another leak-off test was conducted. The leak-off pressure was 393 psi. Calculate the following: Pressure @ Shoe = _______ psi Pressure @ 9,000 ft. = _______ psi Gradient @ Shoe = _______ psi/ft Gradient @ 9,000 ft. = _______ psi/ft EQMD @ Shoe = _______ ppg EQMD @ 9,000 ft = _______ ppg Pressure @ 10,000 ft = _______ psi Pressure @ 11,000 ft. = _______ psi Gradient @ 10,000 ft. = _______ psi/ft Gradient @ 11,000 ft = _______ psi/ft EQMD @ 10,000 ft = = _______ ppg EQMD @ 11,000 ft = _______ ppg Exercise 1-8: If while drilling at 10,500 ft with a mud density of 14.4 ppg,a leak-off test had been conducted, what would the leak-off pressure (pump pressure) have been? Assume the formation at the casing shoe began taking fluid when it experienced the experienced the exact same pressure as in the previous exercise. Leak-Off pressure = _______ psi If the formation at the shoe is the weakest point in the borehole at what depth did the formation take mud during this leak-off test? _______ ft. (Hint: compare the values of EQMD at each depth calculated.)
Hi , fracture pressure @shoe in all cases: 6757.7 psi. Gradient @ shoe in all cases 0.795 and EMD @ shoe all cases 15.28 ppg. While for other pressure your question is not complete. Were you asking about different depth hydrostatic pressure. Depth it will take the liquid is same depth of shoe @8500 feet.
Thank you Abdelaziz Gabr

اسلام وعلیکم اخی معلم جزاک اللہ خیر انت ذہن واللہ
Salaam on you teacher. May allah bless to you
Salute you Sir!
ماشاء اللہ nice
I will get my well control stge 2 at the first time. What should I keep focus to learn? What is unnecessary to learn yet
thank you very much you do the
video in English!!!

Exercise 1-6:
After setting 13-3/8 inch casing, at 8,500 feet, the casing shoe was drilled out and a casing shoe test was run. Leak-off
pressure was determined to be 1,100 psi. The test was conducted with a mud density of 12.8 ppg in the hole.
Calculate the following:
Pressure @ Shoe = _______ psi
Gradient @ Shoe = _______ psi/ft (Shall the pressure/depth be used or MW*.052 because the answers are very different)
EQMD @ Shoe = _______ ppg
Exercise 1-7:
After running the leak-off test in the previous exercise, drilling proceeded to 11,000 ft during which time the mud
density was increased to 14.4 ppg. Another leak-off test was conducted. The leak-off pressure was 393 psi. Calculate the
following:
Pressure @ Shoe = _______ psi Pressure @ 9,000 ft. = _______ psi
Gradient @ Shoe = _______ psi/ft Gradient @ 9,000 ft. = _______ psi/ft
EQMD @ Shoe = _______ ppg EQMD @ 9,000 ft = _______ ppg
Pressure @ 10,000 ft = _______ psi Pressure @ 11,000 ft. = _______ psi
Gradient @ 10,000 ft. = _______ psi/ft Gradient @ 11,000 ft = _______ psi/ft
EQMD @ 10,000 ft = = _______ ppg EQMD @ 11,000 ft = _______ ppg
Exercise 1-8:
If while drilling at 10,500 ft with a mud density of 14.4 ppg,a leak-off test had been conducted, what would the leak-off
pressure (pump pressure) have been? Assume the formation at the casing shoe began taking fluid when it experienced the
experienced the exact same pressure as in the previous exercise.
Leak-Off pressure = _______ psi
If the formation at the shoe is the weakest point in the borehole at what
depth did the formation take mud during this leak-off test? _______ ft.
(Hint: compare the values of EQMD at each depth calculated.)

May Allah grant you Jannat ul firdous thank you so much sir
What o.52? And why we dont make lot in each will
