Well Control Course

Lesson 1 • Wellbore Pressure Relationships

Explains hydrostatic pressure, equivalent circulating density, and pressure windows. Builds the quantitative framework used throughout the course.

Lesson 2 • Drilling Fluid Functions and Properties

Examines how drilling fluid density and rheology maintain primary well control. Links fluid selection to pressure management objectives.

Lesson 3 • Well Architecture and Casing Design

Introduces casing strings, wellhead components, and their roles in containing wellbore pressure. Provides structural context for barrier concepts.

Lesson 1 • Causes of Kicks

Identifies conditions that allow formation fluids to enter the wellbore, including swabbing and lost circulation. Establishes causal understanding before detection skills.

Lesson 2 • Shut-In Procedures and Verification

Details hard and soft shut-in methods and post-shut-in pressure reading procedures. Ensures students can confirm a kick and gather data for kill planning.

Lesson 3 • Primary Kick Indicators

Covers flow rate increase, pit gain, and pump pressure changes as definitive kick signs. Trains rapid recognition of the most reliable surface signals.

Lesson 4 • Monitoring Equipment and Practices

Reviews pit volume totalisers, flow sensors, and mud logging systems used for continuous surveillance. Connects equipment capability to reliable early kick detection.

Lesson 1 • Subsea BOP Considerations

Introduces subsea stack architecture, riser systems, and acoustic or multiplex control differences from surface BOPs. Extends BOP knowledge to offshore deepwater contexts.

Lesson 2 • BOP Control Systems

Covers hydraulic accumulator units, remote panels, and control fluid requirements for reliable BOP actuation. Links control system design to response time requirements.

Lesson 3 • Choke Manifold and Auxiliary Equipment

Examines choke manifold configuration, adjustable chokes, and kill line valves used during well control operations. Prepares students for controlled pressure management.

Lesson 4 • BOP Testing and Inspection

Establishes pressure test procedures, test frequencies, and acceptance criteria for BOP integrity assurance. Connects testing discipline to regulatory compliance and safety.

Lesson 1 • Kill Sheet Preparation

Covers data collection, volume calculations, and kill sheet completion before any kill operation begins. Establishes the calculation foundation for all kill methods.

Lesson 2 • Driller's Method

Details the two-circulation kill procedure, circulating the kick out before weighting up mud. Teaches step-by-step pressure management for the first and second circulations.

Lesson 3 • Volumetric and Lubricate-and-Bleed Methods

Addresses controlled pressure bleed-down techniques when circulation is not possible. Prepares students for non-circulating well control scenarios.

Lesson 4 • Wait and Weight Method

Explains single-circulation kill using pre-weighted kill mud and a declining drillpipe pressure schedule. Compares advantages and limitations against the Driller's Method.

Lesson 1 • Complications During Kill Operations

Covers equipment failures, secondary kicks, and formation breakdown events that disrupt planned kill procedures. Prepares students to adapt kill plans dynamically.

Lesson 2 • Reading and Interpreting Gauges

Trains simultaneous monitoring of drillpipe pressure, casing pressure, and pump stroke rate during kill operations. Builds the situational awareness needed for correct choke adjustments.

Lesson 3 • Choke Operating Principles

Explains how adjusting choke opening controls backpressure and maintains bottomhole pressure during circulation. Connects choke physics to kill method pressure schedules.

Lesson 1 • Well Control Risk Assessment

Applies hazard identification, likelihood-consequence matrices, and bow-tie analysis to well control scenarios. Connects risk tools to pre-job planning and operational decision-making.

Lesson 2 • Incident Investigation and Lessons Learned

Examines root cause analysis methods applied to well control incidents and near-misses. Closes the risk management loop by converting incidents into preventive improvements.

Lesson 3 • Well Barrier Philosophy

Defines primary and secondary barriers, barrier elements, and the principle of maintaining two independent barriers at all times. Provides the conceptual framework for barrier-based well design.

Lesson 1 • High-Pressure High-Temperature Well Control

Covers HPHT pressure and temperature effects on fluid density, equipment ratings, and kick tolerance. Prepares students for the narrow pressure windows common in HPHT wells.

Lesson 2 • Offshore Platform and Jack-Up Operations

Addresses shallow-water BOP configurations, conductor casing challenges, and riser considerations for fixed and jack-up rigs. Connects offshore structural constraints to well control adaptations.

Lesson 3 • Land Drilling Well Control

Reviews surface BOP configurations, diverter systems, and rig-specific shut-in procedures for land operations. Establishes baseline for comparing offshore adaptations.

Lesson 4 • Managed Pressure Drilling Overview

Introduces MPD as a proactive pressure management technique that extends conventional well control capabilities. Positions MPD within the broader well control framework.

Lesson 1 • Capping Stack Operations

Details capping stack design, deployment logistics, and pressure integrity testing after installation. Builds on subsea BOP knowledge to address post-blowout containment.

Lesson 2 • Blowout Response Team Coordination

Addresses incident command structure, specialist contractor roles, and communication protocols during a blowout response. Prepares students for multi-organisation coordination under crisis conditions.

Lesson 3 • Blowout Classification and Dynamics

Classifies surface and underground blowouts by flow path, fluid type, and severity. Establishes the diagnostic framework needed before selecting a response strategy.

Lesson 4 • Post-Blowout Well Integrity Restoration

Examines wellbore integrity assessment, cement remediation, and return-to-production verification after a blowout is controlled. Completes the full blowout response lifecycle.
