Description

This curriculum spans the technical and operational rigor of a multi-workshop field readiness program, covering the same scope of decision-making and execution protocols used in actual well intervention planning, from initial well access through abandonment, with emphasis on real-time data use, cross-team coordination, and compliance-critical validation.

Module 1: Intervention Planning and Operational Readiness

Selecting between slickline, wireline, and coiled tubing based on well deviation, required toolstring weight, and intervention duration.
Developing a well control strategy including BOP stack configuration and pressure testing procedures for live-well operations.
Coordinating with drilling and production teams to schedule interventions during planned production downtime to minimize revenue impact.
Validating wellbore integrity through pressure integrity tests and tubing/casing inspection logs prior to intervention.
Conducting a job safety analysis (JSA) specific to the intervention method, considering H2S presence, surface pressures, and crane operations.
Ensuring real-time data transmission setup between field crew and engineering support for decision escalation during execution.

Module 2: Slickline and Wireline Operations

Choosing between single-shot and continuous conveyance methods based on depth, dogleg severity, and toolstring complexity.
Designing a fishing string configuration when retrieving stuck downhole components such as plugs or gauges.
Calibrating depth measurement systems using casing collar logs to ensure precise tool placement in deviated wells.
Managing wireline tension and overpull limits to prevent parting while avoiding excessive stress on the lubricator and BOP.
Implementing real-time tension and depth monitoring to detect anomalies indicating tool hang-up or wellbore obstruction.
Executing controlled perforation operations using through-tubing guns, balancing charge density with casing damage risk.

Module 3: Coiled Tubing Interventions

Sizing coiled tubing diameter and wall thickness based on required burst/collapse pressure and reach in high-angle wells.
Designing a nitrogen or fluid lift procedure to remove wellbore fluids and re-establish production after workover.
Managing fatigue life tracking of coiled tubing reels using real-time strain monitoring and historical bending cycle logs.
Executing a cleanout operation with jetting tools, optimizing fluid rate and viscosity to suspend and remove sand or scale.
Deploying coiled tubing for chemical squeeze jobs, ensuring proper placement and shut-in time for formation absorption.
Integrating real-time downhole pressure and temperature sensors to monitor progress during milling or drilling-out operations.

Module 4: Hydraulic Workover and Snubbing

Choosing between hydraulic workover (HWO) and snubbing units based on wellhead pressure and required stroke length.
Designing a snubbing BOP configuration that accommodates multiple pipe rams, blind shear rams, and annular preventers.
Calculating overbalance or underbalance conditions to safely strip pipe into a live well without causing formation damage.
Managing dynamic friction pressures during pipe movement to avoid exceeding formation fracture gradients.
Implementing a pipe handling system that minimizes personnel exposure during joint make-up and break-out.
Conducting pressure testing of all pressure-containing components after assembly, including kill and choke lines.

Module 5: Stimulation and Production Enhancement

Designing an acid stimulation program for carbonate formations, selecting acid type, concentration, and injection rate.
Monitoring downhole pump pressure and rate during matrix acidizing to avoid exceeding fracture pressure unintentionally.
Deploying diverting agents in multi-zone treatments to ensure uniform stimulation across perforated intervals.
Integrating post-stimulation production logging to evaluate treatment effectiveness and identify bypassed zones.
Managing spent acid return flowback with corrosion-resistant handling equipment and neutralization procedures.
Coordinating with reservoir engineers to interpret pressure buildup tests after stimulation for productivity index validation.

Module 6: Sand and Scale Management

Installing downhole sand detection gauges to monitor sand production trends before planning mechanical interventions.
Selecting between chemical inhibition and mechanical filtration (e.g., gravel packs, screens) based on sand production rate.
Designing a scale squeeze treatment, including pre-flush, inhibitor volume, and overflush displacement.
Conducting a scale removal operation using milling tools or chemical dissolvers based on scale composition analysis.
Evaluating the risk of re-precipitation after scale dissolution by monitoring downhole fluid chemistry during cleanout.
Implementing real-time sand rate monitoring during interventions to trigger shutdown if thresholds are exceeded.

Module 7: Well Abandonment and Plug-and-Abandonment (P&A)

Designing cement plug placement strategy to meet regulatory requirements for zonal isolation in multiple formations.
Selecting between cement squeezing and mechanical bridge plugs based on casing integrity and pressure containment needs.
Conducting cement bond logging after plug placement to verify top-of-cement and bonding quality.
Executing section milling operations to remove casing sections when required by abandonment regulations.
Documenting all P&A operations with depth-accurate reports, pressure tests, and verification logs for regulatory submission.
Managing cuttings and fluid disposal from milling operations in accordance with environmental compliance protocols.

Module 8: Real-Time Data Integration and Decision Support

Configuring surface sensors to capture real-time hook load, fluid pressure, and pump rate during intervention execution.
Integrating downhole telemetry systems with surface data acquisition for immediate detection of tool malfunctions.
Establishing data-sharing protocols between contractor personnel and operator engineering teams during critical operations.
Using real-time pressure monitoring to detect communication between zones during stimulation or cementing jobs.
Applying automated alerts for operational thresholds such as overpull, undergauge conditions, or fluid losses.
Archiving intervention data in a structured format for post-job analysis and future well planning reference.
