The IADC WellSharp Supervisor Level Well Control course is essential training for those working in wellsite supervisory roles and for office-based personnel that are primarily involved in the operational decision-making process and/or well design. The course aims to build on the Driller Level course content (including kick detection and shut-in) and focus on more complex aspects of well control and well kill methodology.
Designed For: The IADC WellSharp "Well Control for Drilling Operations – for Supervisors" course has been designed for toolpushers, drilling engineers, drilling supervisors, superintendents, drilling foremen, company men and others with a requirement to hold an accredited well control certificate at Supervisory level. The training is role-specific and is focused on well kill procedures.
The course is delivered over 5 days through presentation of a series of interactive lectures supported by videos and animations, supplemented by a classroom workbook and further self-study exercises and practical work on a drilling simulator.
Under the WellSharp programme and unlike IWCF training, IADC Supervisor Level candidates are taught completely separately from IADC Driller Level candidates and will not be in a mixed class. The course ends with an online assessment on the final day which will be administered by IADC and invigilated by an independent proctor.
Accrediting Body: IADC
Course Duration: 5 Days
Course Validity: 2 Years
NOTE: If conducted on-site client should provide classroom or other suitable quiet area with chairs, desks, whiteboard, & overhead projector.
At the end of this course, participants will be able to:
Perform static and dynamic pressure calculations across a range of wellbore and formation conditions
Calculate volumes and capacities for a range of drilling and tripping operations and calculate the effects on bottom-hole pressure during these operations
Explain the effects of gas migration on wellbore pressures
Describe the causes of kicks for on-bottom and off-bottom conditions
Explain the procedures for shutting in a well for a range of operations
Complete a kill sheet for vertical and deviated wells
Specify the well control equipment requirements for surface and subsea operations
Describe the principles underpinning the constant bottom hole pressure methods of well kill
Using a simulator, determine the appropriate well kill method, instruct the driller and successfully kill the well
Indicative Course Content:
The course covers the following modules::
Drilling, workover and completion plan
This section of the course looks at the overall well objectives including well planning, casing and cementing programme, completion programme, fluids programme, the completions programme, barrier management, kick tolerance and pore pressures.
Well control concepts
under this topic the delegate will learn about: basic characteristics of geology and rock formations, hydrostatic pressure, U-tube principles, capacities and displacements, static and dynamic wellbore pressure, formation stresses and strength, surge and swab pressures, MAASP, gas behaviour in fluids, the effect of temperature and pressure on drilling fluids, well control in high angle wells, the effects of a tapered drillstring, identifying ballooning.
Mud and pit management The importance of mud and pit management is explored through: functions and type of drilling fluid, measuring fluid density, fluid contaminants and effect of temperature, maintaining fluid weight, pit management during normal operations, and pit management during kill operations.
Pre-recorded data The section of the course looks at slow circulation rates, pre-kill kick sheets, kill line fluids.
Abnormal pressure warning signs Topics covered include: shaker evidence, changes in mud properties, changes in drilling parameters, mud weight management while drilling a transition zone, and trend analysis.
Kick prevention during drilling, casing and cementing operations The avoidance of the need for well control through kick prevention is stressed. Topics include: Tripping operations, handling losses, interpreting a kick from ballooning, wellbore fluid displacement, wireline operations, inflow testing, well control drills, cementing and casing considerations.
Barriers The importance of robust barrier testing, identification and use is covered in depth. Risk management including: assessing risks, safety margin selection, managing change during a kill operation, handling kill problems, the need for bridging documents and emergency procedures.
Tophole drilling The special well control case of tophole drilling is discussed with respect of:shallow gas, shallow gas detection methods, options in tophole, cause of underbalance in tophole, tophole drilling and tripping procedures, the correct line up and use of diverters.
Kick detection and shut-in The need for vigilance in identifying a flowing well is strongly emphasised: well flow with pumps off, pit gains, flow return rate increase, importance of early response and stop work authority. Shut-in methods using hard and soft shut-in are described for drilling and tripping operations and for running casing, wireline and non-shearable tubing. Following shut-in the need for recording shut-in data, monitor for gas migration, trapped pressure, identifying ballooning, opening float valve, equipment line up. Well control drills are described in detail.
Well control methods This section of the course looks at the basic principles and differences between the constant bottom hole pressure methods including: Driller’s Method, Weight and Wait, Volumetric Method, Bullheading and handling gas in the riser, kill problems, pump start up, lube and bleed, stack gas clearing, displacing riser post kill.
Equipment The equipment section looks at: diverters, equipment alignment and stack configuration, BOP stack, valves and wellhead components, manifolds, piping and valves, drillstring valves, instrumentation, gas detection equipment, BOP closing unit, monitoring equipment, mud gas separator, control chokes and manifolds, stripping and tripping tanks.
Prior IWCF or IADC certification at Driller or Supervisor Level is recommended but not mandatory. The training is role-specific so previous experience in a supervisory role during drilling operations is assumed. Please contact us to discuss candidate suitability if you have any doubts or queries.
Candidates may select either "Combined" (Surface & Subsea) or "Surface Only" BOP Stack certification. Successful completion of the course and a pass mark of 70% or above in the practical simulator assessment and the online written assessment will result in IADC WellSharp Supervisor Level certification which is valid for two years.
