Well completion from barrier design and perforation through wireline and coiled tubing intervention, stimulation, sand control, and the design, operation, and troubleshooting of rod pump, gas lift, and ESP artificial lift systems.
Led by Senior Reservoir Engineer Simulacrum
The question
Every completion decision is a trade-off that lives with the well for decades. This module develops the barrier philosophy (primary and secondary barriers, annulus monitoring, DHSV testing), completion types from single-zone through intelligent completions, lower completion options for sand control (standalone screens, gravel packs, frac-packs and the gravel sizing criterion), upper completion components and their selection (tubing sizing by nodal analysis, packer, DHSV fail-safe principle, christmas tree valves), perforation design parameters and the advantage of underbalanced perforating, and cement bond verification.
Outcome
The student can describe the barrier concept and its verification, explain completion types and sand control options with their selection criteria, specify perforation parameters for a given scenario, and explain the advantage of underbalanced perforating. (Well completion design)

The question
Wireline is the simplest and fastest way to access a completed wellbore — a cable through the christmas tree carrying a tool that measures, acts, or repairs. This module covers slickline vs. braided line and what determines the choice, the lubricator and wireline BOP as the pressure containment system, the four production logging tools (spinner, gradiomanometer, temperature, capacitance probe) and the flow profile they construct, cased-hole logging for corrosion and cement assessment, and the fishing workflow from lead impression block through tool selection to recovery.
Outcome
The student can distinguish slickline from braided line operations, describe the production logging tools and interpret a simplified flow profile, describe three cased-hole logging tools and the condition each diagnoses, and explain the fishing workflow. (Wireline services)

The question
Coiled tubing does what wireline cannot — it pushes, and it circulates. This module covers the CT equipment train and its capabilities vs. wireline and workover, wellbore cleanout and nitrogen lift procedures, matrix acidising for carbonates (HCl and wormholing) and sandstones (mud acid with pre-flush and post-flush), hydraulic fracturing (fracture creation, proppant, and the distinction from matrix stimulation), and through-tubing sand control installation for mature wells where the original completion did not include sand management.
Outcome
The student can describe the CT equipment and its advantages over wireline, explain the difference between matrix acidising and hydraulic fracturing, describe acid selection for carbonate vs. sandstone, and explain the through-tubing sand control procedure.

The question
Every reservoir declines, and at some point the natural energy is insufficient to lift fluids to surface. The artificial lift selection matrix maps five well parameters (rate, depth, GOR, water cut, intervention access) against rod pump, gas lift, and ESP capabilities to identify the right method. This module develops the selection matrix, then goes deep on the rod pump: the beam unit, the downhole pump, the sucker rod string, the pumping cycle, and the dynamometer card — the diagnostic tool that reveals fluid pound, gas interference, rod parting, and worn pump from the shape of the force-displacement plot.
Outcome
The student can apply the selection matrix to recommend a lift method for a given well, describe the rod pump system and pumping cycle, interpret a dynamometer card to diagnose four failure modes, and prescribe the correct stroke adjustment for each. (Artificial lift selection and rod pumping)

The question
Gas lift and ESP are the two dominant methods for high-rate wells. Gas lift injects gas to lighten the fluid column — no moving parts downhole, longest run life. ESP installs a centrifugal pump in the wellbore — highest deliverable rates but mechanical failure after 2–4 years. This module develops the design, operation, and troubleshooting of both: the gas lift performance curve and valve placement sequence, the slope-equalisation allocation method for multi-well systems, ESP selection using pump curves and the affinity laws, VSD rate control, and failure mode diagnosis from surface data signatures.
Outcome
The student can design a gas lift system and apply the slope-equalisation allocation method, diagnose three gas lift troubleshooting scenarios, describe the ESP selection methodology, and diagnose four ESP failure modes from surface signatures. (Gas lift and ESP — design, operation, and diagnosis)
