Lesson 1
Well Control

14. Well Control Kick Blowout
“an unscheduled entry of formation fluids into the wellbore, of sufficient Quantity to require shutting in the well.
Blowout
Loss of control of a kick

15. Blowout

16. Blowouts

17. Well Control Blowout Blowouts caused by Surface Underground
equipment failure
human error

18. Well Control Engineers in office can aid in well control by:
Provide pressure profiles for all pending wells
Provide offset information such as logs, bit records, mud reports, drilling records.
Provide support and assistance personnel on location.

19. Well Control Terminology
Hydrostatic pressure = .052 x MW x TVD

20. Hydrostatic Pressure Derive HSP equation
Calculate the HSP for each of the following:
10,000’ of 12.0 ppg mud
12,000’ of 10.5 ppg mud
5,000’ of 11.2 ppg mud on top of 6,000’ of 16.5 ppg mud

21. Hydrostatic Pressure Derive HSP equation Weight of fluid = A
Area = A, sq.ft.
Height = h, ft.
Density = MW, ppg
Weight of fluid =
A*h (ft3)*62.4 lb/ ft3 *MW/8.33
=62.4/8.33*MW*A*h h MW

22. Hydrostatic Pressure
This weight is equally distributed over an area of A sq.ft or 144*A sq. in.
Pressure = Weight (force)/area
= 62.4*MW*A*h
8.33*144*A
P=.052*MW*h where h=TVD

23. Terminology Pressure Gradient Formation Pressure psi/ft = .052 x MW
ppg equivalent
Formation Pressure
Normal pressure
Abnormal pressure
Subnormal pressure

24. Terminology Overburden pressure Fracture pressure
function of rock and fluid above zone of interest
Fracture pressure

25. Terminology
Pump pressure or system pressure loss

26. Terminology Slow Pump Pressure Taken: every tour by each driller
pumps repaired or liners changed
mud properties change
every 500’ of hole
change in BHA
bit nozzles changed

27. Terminology
Surge pressure
Swab pressure

28. Terminology Shut-in drillpipe pressure - SIDPP
FP = HSPdp + SIDPP
Shut-in casing pressure - SICP
FP = HSPcsg mud + HSPinflux + SICP
Bottom-hole pressure - BHP
BHP = HSP + SIP + Friction + Surge - Swab

29. U-Tube Concept

30. Basic Calculations
Dia, in - cap, bbl/ft

31. Basic Calculations
Pump Output
Duplex Pump
Triplex Pump

32. Basic Calculations

33. Basic Calculations Kill Weight Mud KWM = SIDPP/(0.052 x TVD) + OWM
KWM = FP/(0.052 x TVD)

34. Weight material to add to increase density
