1. Lesson 4 Cementing

2. Harold Vance Department of Petroleum Engineering Cementing Read: Halliburton Book Multimedia Program # 8 Casing and Cementing

3. Harold Vance Department of Petroleum Engineering Cementing Functions of cement Cement Types Additives

4. Harold Vance Department of Petroleum Engineering Functions of cement Protect and support the casing Prevent the movement of fluid through the annular space outside the casing

5. Harold Vance Department of Petroleum Engineering Functions of cement Stop the movement of fluid into vugular or fractured formations

6. Harold Vance Department of Petroleum Engineering Functions of cement Close an abandoned portion of the well

7. Harold Vance Department of Petroleum Engineering Types of cemeting processes Primary cementing Full string Liners Large diameter pipe Stage Survey and perforate Stage collar

8. Harold Vance Department of Petroleum Engineering Types of cemeting processes Squeeze cementing Shoe Casing (up hole) Open-hole (lost circulation)

9. Harold Vance Department of Petroleum Engineering Types of cemeting processes Plug and Abandonment Open hole plug back Fishing operations Abandonment Casing

14. Harold Vance Department of Petroleum Engineering Additives

15. Harold Vance Department of Petroleum Engineering Cementing Calculations Given: Casing = 7”, 23 lb/ft casing to be set at 8000’ Hole OD = 9” Cement the bottom 2000’ of casing Class “H” neat, 15.6 ppg 80’ casing between float collar and float shoe

16. Harold Vance Department of Petroleum Engineering Cementing Calculations Determine: Volume of cement required Volume of mixing water Volume of mud displacement

17. Harold Vance Department of Petroleum Engineering Cementing Calculations Solution: Yield of cement = 1.18 cu.ft/sk (Halliburton) Cement volume Annular Capacity = .1745 cu ft/ft (Halliburton) Annular Vol = .1754 cuft/ft X 2000’ = 349 cu ft Casing Capacity = .2210 cu ft/ft Casing Volume = .2210 X 80 = 17.68 cu. ft. Cement volume = 349 + 17.68 cu. Ft = 366.68 cu. ft.

18. Harold Vance Department of Petroleum Engineering Cementing Calculations Sacks of cement = 366.68 cu.ft/1.18 cu.ft/sk Sacks of cement = 310.75 sacks Volume of mixing water = 5.2 gal/sack X 310.75 sacks = 1615.88 gal 1615.88 gal/42gal/bbl = 38.47 bbl

19. Harold Vance Department of Petroleum Engineering Cementing Calculations Volume of Mixing Water Volume of mixing water = 5.2 gal/sack X 310.75 sacks = 1615.88 gal 1615.88 gal/42gal/bbl = 38.47 bbl

20. Harold Vance Department of Petroleum Engineering Cementing Calculations Mud displacement Casing capacity = .0396 bbl/ft Depth to FC = 8000 – 80 = 7920’ Volume of mud displacement = .0396 X 7920 = 313.63 bbl
