Wellbore Survey

–Background

•Recently, technology have advanced in such away that the former directional drilling tools were replaced with an advanced ones such as:

–Steerable mud motors,

–MWD,

–Andergauge Stabilizers,

–LWD.

•These tools, in combination, could provide  a 3D well profiles without changing BHA and have enabled the drilling of horizontal and multi lateral wells.

WELL CONTROL EQUIPMENT (NEXT NETWORK OF EXCELLENCE IN TRAINING)

WELL CONTROL EQUIPMENT (NEXT NETWORK OF EXCELLENCE IN TRAINING)

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.
