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 course on Wireline Operations and Techniques in the Oil & Gas Industry 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 Wireline Operations and Techniques in the Oil & Gas Industry course, participants will:
