Rams
Variable Bore Rams
1.The Variable Bore Ram, or VBR, seals on several sizes of pipe
or hexagonal kelly within its specified size range. A typical range is from
5" to 3-1/2" diameter Other size ranges, such as 7" to
4-1/2" diameter, are available upon request.
2.VBRs are not intended for long-term stripping use.
3."Stripping" refers to moving drill pipe vertically
within the well while the BOPs remain closed, maintaining a seal around the
pipe.
4.During stripping, the drill pipe and larger diameter tool
joints are pulled through the packers in fully closed rams. This procedure is
typically used in workover and servicing operations using annular BOPs and specialty
rams.

BASIC WELL CONTROL (NEXT NETWORK OF EXCELLENCE IN TRAINING)
BASIC WELL CONTROL (NEXT NETWORK OF EXCELLENCE IN TRAINING)
•Lecture Contents;
–Lecture Objectives,
–Introduction,
–Primary Control,
–Warning Signs of Kicks,
–Secondary Control,
–Well Killing Procedures,
–Kill Sheet.
•Lecture Objectives
–At the end of this lecture YOU will
be able to:
•Define the term “kick”,
•State warning signs of a kick,
•Describe the drawback of uncontrolled
kicks,
•State primary and secondary control
procedures,
•List well killing procedures and the
various calculation to fill-up the well control work sheet.
•Introduction;
–In simple terms, kick occur when the
formation pressure exceeds the mud hydrostatic pressure,
–The resultant negative differential
pressure is forced into the wellbore,
–If the flow of the kick is controlled
then the well is killed,
–Blow-out occurs when the kick
(influx) is uncontrolled,
–The rig crew must be alert all times
in order to take immediate action to bring the well under control.

v Lecture
Objectives:
At the end
of this course, YOU will be able to:
Ø Understand the difference between
primary and secondary cementing,
Ø Identify classes of cement
appropriate for different depth range,
Ø Explain how the properties of cement
may be altered by the use of additives,

v Introduction;
ü Primary
cementing is the introduction of cementacious material into the annulus between
casing and openhole to:
Ø Provide
zonal isolation,
Ø Support
axial load of casing string and other strings to be run later,
Ø Provide
casing protection,
Ø Support the
borehole,
ü Secondary/or
Remedial jobs:
Ø Squeeze
cementing,
Ø Cement plug.

CASING DESIGN PRINCIPLES (TRAINING SOLUTIONS)
CASING DESIGN PRINCIPLES (TRAINING SOLUTIONS)
•Lecture Contents;
–Lecture Objectives,
–Definitions,
–Casing Design Criteria,
•Collapse,
•Burst,
•Tension.
•Lecture Objectives
–At the end of this lecture YOU will
be able to:
•Be familiar with the design criteria
that is taken into consideration when a casing string is to be designed with
respect to:
–Collapse,
–Burst,
–Tension.
•List the design safety factors.
•Definition;
–Casing design involves the determination of factors which
influence the failure and the selection of the most suitable casing grades and
weights for specific operations,
– The casing program should also reflect the completion and
production requirements,
–A good knowledge of the stress analysis and the ability to
apply it are necessary for the design of casing strings.
