IWCF Level 3 DWC study plan

IWCF Level 3 DWC · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Drilling Well Control

  • Define primary well control barrier and secondary well control barrier, and list which physical equipment serves each role on a typical rig

  • Explain how formation pressure, hydrostatic pressure, and bottom hole pressure relate, and calculate BHP from mud weight and true vertical depth in both SI and field units

  • Derive mud weight required to balance a stated pore pressure gradient, and state why overbalance margin is applied

  • Convert between pressure gradient, mud weight, and equivalent mud weight (EMW) for at least five worked examples

Your checkpoint

A one-page formula sheet plus 20 self-worked pressure and EMW calculations, all correct on second pass

Week 2

Drilling Well Control

  • Identify the causes of kicks grouped as swabbing, lost circulation, insufficient mud weight, and abnormal pressure, and give a rig-floor trigger for each

  • Describe the sequence of events that produces a swab kick during a trip, including tripping speed, gel strength, and bottom hole pressure reduction

  • Explain kick tolerance and annular capacity concepts and why they limit how far a well can be drilled ahead

  • Distinguish shallow gas hazards from deeper kick scenarios and state the operational differences in response

Your checkpoint

A cause-and-effect table linking 10 kick causes to their warning signs and the first corrective action for each

Week 3

Drilling Well Control

  • List positive kick indicators and interpret them against pit gain, flow rate, and pump pressure changes

  • Explain the difference between a positive indicator and a negative indicator of a kick and give three examples of each

  • Describe the correct first actions on detecting a kick while drilling, while tripping, and while static, and state why shutting in fast preserves influx size

  • Analyze how pit gain and shut-in drill pipe pressure behave in a gas influx versus a saltwater influx

Your checkpoint

A written kick-detection decision tree covering drilling, tripping, and static conditions, with the alarm threshold stated for each

Week 4

Drilling Well Control

  • Explain the purpose of the soft shut-in and hard shut-in procedures and compare their advantages and risks

  • Describe how to record shut-in drill pipe pressure (SIDPP) and shut-in casing pressure (SCP) and what each reading tells you about influx and formation pressure

  • Calculate formation pressure from SIDPP and current mud weight, and calculate kill mud weight

  • Explain what a stabilized SIDPP confirms and what pressure behaviour suggests an influx is still migrating

Your checkpoint

A step-by-step shut-in checklist with the pressure readings to record and the kill mud weight calculation worked for three scenarios

Week 5

Drilling Well Control

  • Describe the driller's method sequence and state which pressure is held constant on each circulation

  • Describe the wait and weight method and compare its pressure schedule with the driller's method

  • Explain initial circulating pressure, final circulating pressure, and the slow circulating rate pressure used to build the kill sheet

  • Calculate kill mud weight, initial circulating pressure, and final circulating pressure for a worked example

Your checkpoint

A completed kill sheet for one scenario, showing SIDPP, SCP, slow circulating pressure, kill mud weight, ICP, FCP, and the pressure step-down schedule

Week 6

Drilling Well Control

  • Explain the behaviour of SIDPP and SCP when gas is allowed to migrate with the well shut in, and state the correct action

  • Describe the volumetric method for allowing gas to expand while holding casing pressure within limits

  • Explain why casing shoe pressure is the limiting constraint and how to check it against formation fracture pressure

  • Identify what happens to bottom hole pressure if gas is circulated out without allowing expansion

Your checkpoint

A migration and volumetric control worksheet with casing shoe pressure calculated and compared to fracture pressure for two scenarios

Week 7

Drilling Well Control

  • Describe well control equipment functions: BOP stack arrangement, choke manifold, accumulator, and choke line, and state the purpose of each in a kill operation

  • Explain the function of the annular preventer versus the pipe rams and when each is used

  • Describe choke adjustments needed to hold casing pressure on the gauge while bringing the pump to kill rate

  • Explain the risks of a kick while tripping, including the use of a trip tank, and the actions to take

Your checkpoint

An equipment-and-actions summary covering the BOP stack, choke manifold, and accumulator, with the correct choke response described for three pressure scenarios

Week 8

Drilling Well Control

  • Re-derive every key formula from memory: hydrostatic pressure, EMW, kill mud weight, ICP, FCP, and casing shoe pressure

  • Work through five timed mixed scenarios covering kick detection, shut-in, kill method selection, and migration control

  • Identify personal weak areas from the timed scenarios and close each gap with targeted re-study

  • State the standard well control actions and reporting sequence expected of a Level 3 candidate in a kick situation

Your checkpoint

A timed 90-minute mock assessment of 25 mixed calculation and procedure questions, scored with a written list of weak areas and the corrective study for each

Milestones

Week 2: Score at least 80 percent on a self-made 15-question quiz on pressures, gradients, EMW, and kick causes, with all calculation errors corrected

Week 4: Shut in a simulated well and record SIDPP and SCP correctly, then calculate kill mud weight without reference notes

Week 6: Complete a kill sheet and casing shoe pressure check within 30 minutes with no formula lookup

Week 8: Score at least 85 percent on the timed 90-minute mock assessment, with no repeated error type from earlier weeks
