Wireline service engineering from equipment and pressure control through open-hole and cased-hole logging, formation evaluation, perforation design, explosives safety, data acquisition and quality control, and HPHT wireline operations.
Led by Senior Well Intervention & Artificial Lift Engineer Simulacrum
The question
Before running any tool, the wireline engineer must understand the system that deploys it safely. This module covers the wireline unit components (drum, cable, measuring head), the three cable types and what determines the choice between them, the lubricator sizing requirement and the wireline BOP functions (pack-off and shear), the grease injection system for dynamic cable sealing, tool string assembly and the safety-critical assembly checklist, the rig-up procedure from BOP installation through tool deployment, and the wireline-specific hazards including radioactive source handling.
Outcome
The student can describe the wireline unit and three cable types, explain the lubricator and BOP functions, trace the rig-up procedure, and identify four wireline-specific hazards with their controls. (Wireline systems and pressure control)

The question
Open-hole logging is the one opportunity to measure the formation before casing is set — the measurements made in this window are the foundation of every subsequent engineering decision. This module develops the six standard tools (GR, SP, resistivity, density, neutron, sonic), the density-neutron crossplot for gas identification and lithology discrimination, the formation micro-imager for fracture and stress direction identification, the modular formation dynamics tester for pressure and fluid sampling, and the formation evaluation workflow from depth matching through net pay determination.
Outcome
The student can describe all six standard open-hole tools, interpret a density-neutron crossplot for gas and lithology, describe the FMI and MDT and their applications, and outline the formation evaluation workflow from raw log to net pay. (Open-hole logging and formation evaluation)

The question
The producing well cannot be measured directly — the formation is behind casing. Cased-hole logging measures the condition of the casing (multifinger caliper, EM thickness, MFL, acoustic televiewer), the quality of the cement (CBL/VDL and what distinguishes full bond from micro-annulus), the production flow profile (the four-sensor PLT suite), fluid saturation behind casing (PNC for saline formations, C/O for low-salinity), and leak detection (noise logging and temperature anomalies). Each tool answers a specific production or integrity question.
Outcome
The student can describe the four casing inspection tools, interpret a CBL/VDL for cement bond quality, construct a flow profile from PLT data, explain the PNC and C/O saturation monitoring principles, and describe the noise and temperature methods for leak detection.

The question
Perforation creates the flow path from reservoir to wellbore using shaped explosive charges that accelerate a metal jet to 7,000 m/s through casing, cement, and formation. This module covers the shaped charge physics, the three gun types (through-tubing, casing, TCP) and their deployment methods, perforation design parameters (density, phasing, charge type, depth control via CCL), the underbalanced perforating advantage, and the explosives safety framework — transportation, storage, arming, firing, and misfire management — with the charge inventory reconciliation that closes every job.
Outcome
The student can describe the shaped charge mechanism, explain the three gun types, specify perforation parameters for a given scenario, describe the five phases of explosives management, and explain the charge inventory reconciliation requirement. (Perforation services and explosives safety)

The question
The quality of wireline data determines the quality of every engineering decision made from it. This module develops the two acquisition modes (surface readout vs. memory), the three-stage calibration process (master, before-survey, after-survey), the real-time quality control checks including the repeat section as the primary proof of data quality, HPHT wireline challenges (tool temperature limits, time-at-temperature, cable insulation monitoring, abort criteria), and the stuck-tool and fishing workflow — including the regulatory consequences of an abandoned radioactive source.
Outcome
The student can describe both acquisition modes, explain the three-stage calibration process, identify three real-time QC checks, describe the HPHT-specific challenges and abort criteria, and explain the regulatory consequence of an abandoned radioactive source.
