Wireline Operations and Techniques in the Oil & Gas Industry

Introduction:

Current essential oilfield activities heavily depend on wireline oil and gas operations, which utilize a rigid steel thin wire mounted on a panel, powered by a reel and pulley system. Wireline operators play a crucial role by performing diagnostics, troubleshooting, and carrying out completion and production maintenance using wireline equipment.

This module on oil and gas wireline operations and techniques focuses on the deployment of various perforating charges through precise firing techniques at predetermined depths, back-off operations for stuck pipes, object retrieval, and the management of complex wellhead pressure and flow control systems.

By the end of this section, learners will gain a clear understanding of the wireline operator's job classification, alongside management issues related to the development of oilfield wireline operations. They will also consider various operations performed using wireline tools.

Objectives:

At the end of this oil and gas wireline operations and techniques course, participants will:

• Identify and describe the use of slick line and wireline tools.
• Identify and describe the Pressure Control Equipment and Bottom-hole assemblies designed for slick line and wireline interventions.
• Describe typical applications for slick line and wireline interventions.
• Critically evaluate each intervention type, including the advantages and disadvantages for various job problems.
• Highlight key work design features required within the scope of the contractor's proposal.
• Address risks associated with each type of intervention and possible mitigation controls.
• Promote safety, effectiveness, and efficiency of rigless intervention by incorporating industry practices and experiences.
• Integrate current knowledge of wireline tools and operations in oil and gas well operations, servicing, workovers, and production.
