IWCF/IADC WellCAP Certification Preparation Course

Lesson 1 • Formation Pressure and Pore Pressure

Covers origin of formation pressure, normal vs. abnormal gradients, and detection methods. Establishes the baseline pressure knowledge required throughout the course.

Lesson 2 • Pressure Measurement and Units

Reviews pressure units, conversion factors, and gauge vs. absolute pressure. Ensures accurate numerical communication across all well control calculations.

Lesson 3 • Hydrostatic Pressure and Mud Weight

Explains how fluid columns generate hydrostatic pressure and how mud weight controls wellbore stability. Directly supports understanding of primary well control.

Lesson 4 • Fracture Pressure and Wellbore Integrity

Defines fracture gradient, leak-off test interpretation, and casing shoe limitations. Connects pressure limits to safe drilling window design.

Lesson 1 • Kick Detection While Tripping

Addresses the unique challenges of detecting kicks during pipe trips, including fill-up monitoring. Prepares students for the highest-risk operational phase.

Lesson 2 • Confirming and Sizing the Influx

Teaches shut-in pressure readings and pit gain analysis to quantify influx type and volume. Provides data needed for selecting the correct kill method.

Lesson 3 • Primary Causes of Kicks

Examines conditions that allow formation fluids to enter the wellbore, including swabbing and lost circulation. Establishes causal understanding needed for prevention.

Lesson 4 • Secondary Kick Indicators

Covers supporting indicators including drilling break, torque changes, and background gas. Reinforces multi-indicator recognition for reliable kick confirmation.

Lesson 1 • Subsea BOP Systems

Introduces subsea stack design, riser systems, and control pod redundancy for offshore operations. Extends BOP knowledge to deepwater well control scenarios.

Lesson 2 • Accumulator and Control Systems

Explains hydraulic accumulator function, pre-charge pressure, and remote control panels. Ensures students understand the power source for BOP actuation.

Lesson 3 • Choke and Kill Line Systems

Covers choke manifold layout, kill line routing, and valve functions during well control operations. Connects surface equipment to wellbore pressure management.

Lesson 4 • BOP Stack Components and Configuration

Describes ram preventers, annular preventers, and stack arrangement for land and offshore rigs. Establishes equipment literacy required for all subsequent BOP operations.

Lesson 1 • Shut-In Procedure While Tripping

Covers shut-in steps specific to tripping operations, including stabbing a safety valve. Addresses the elevated risk and limited equipment access during pipe trips.

Lesson 2 • Shut-In Procedure While Drilling

Provides the step-by-step shut-in sequence for rotary drilling operations, including pump shutdown. Builds procedural competency for the most common operational state.

Lesson 3 • Maximum Allowable Annular Surface Pressure

Defines MAASP, its calculation from leak-off data, and its role as a pressure ceiling during kill operations. Prevents formation fracture during well control procedures.

Lesson 4 • Hard Shut-In vs. Soft Shut-In

Compares immediate closure versus choke-open shut-in methods, including their advantages and risks. Establishes the decision framework for initial well control response.

Lesson 1 • Kick Tolerance Calculation

Defines kick tolerance and calculates the maximum allowable influx volume before fracture risk. Supports pre-drill planning and real-time decision-making during drilling.

Lesson 2 • Wellbore Volume Calculations

Covers capacity and volume formulas for drillpipe, drill collars, annuli, and open hole. Accurate volume data is essential for timing kill mud arrival and influx displacement.

Lesson 3 • Kill Sheet Completion and Verification

Guides students through completing a full kill sheet from raw data to operational parameters. Includes cross-checking methods to catch arithmetic errors before execution.

Lesson 4 • Slow Pump Rate and Circulating Pressure

Explains slow circulating rate pressure measurement and its use in kill pressure schedules. Establishes the reference pressure baseline for choke management during kills.

Lesson 1 • Driller's Method

Explains the two-circulation kill approach: first circulating the kick out, then circulating kill mud in. Covers pressure schedules and choke management for each circulation.

Lesson 2 • Wait and Weight Method

Details the single-circulation kill using pre-weighted kill mud, including the pressure schedule graph. Demonstrates efficiency advantages over the Driller's Method.

Lesson 3 • Kill Weight Mud Calculation

Derives kill mud weight from shut-in drillpipe pressure and current mud weight. This calculation is the foundation for all circulating kill methods.

Lesson 4 • Volumetric and Lubricate-and-Bleed Methods

Covers pressure-controlled methods used when pipe is off-bottom or circulation is impossible. Extends kill competency to non-standard well control scenarios.

Lesson 1 • Subsea and Deepwater Well Control

Covers riser margin, subsea BOP operation, and deepwater-specific pressure management challenges. Extends well control competency to offshore deepwater environments.

Lesson 2 • Kicks in Horizontal and Deviated Wells

Explains how wellbore geometry affects influx behaviour, pressure readings, and kill mud placement. Adapts standard calculations for non-vertical well profiles.

Lesson 3 • Kicks During Cementing Operations

Identifies pressure vulnerabilities during primary cementing and displacement operations. Applies shut-in and kill procedures adapted for cementing equipment configurations.

Lesson 4 • Gas Kicks and Gas Migration

Addresses the behaviour of gas influx in the wellbore, including expansion and migration rates. Prepares students to manage the most hazardous and dynamic kick type.

Lesson 1 • Review, Gap Analysis, and Final Readiness

Identifies individual knowledge gaps through diagnostic review and targeted remediation exercises. Confirms each student meets the competency threshold before the certification exam.

Lesson 2 • Practical Well Control Simulation

Simulates hands-on BOP operation, choke management, and kill execution in a controlled setting. Prepares students for the practical component of the certification assessment.

Lesson 3 • Scenario-Based Written Practice

Presents realistic well control scenarios requiring integrated knowledge across all course topics. Develops the analytical reasoning needed for complex exam questions.

Lesson 4 • High-Frequency Calculation Drills

Provides timed repetition of kill weight, MAASP, kick tolerance, and volume calculations. Builds speed and accuracy for the numerical portions of the certification exam.
