A Wireline Engineer’s Approach to Ensuring Safety in TCP Operations

As wireline engineers, we deal with critical operations every day, and safety is always our top priority. One operation that carries inherent risks is downloading explosives from the toolstring, particularly when dealing with misruns, canceled operations, or any unexpected issues that require us to safely remove the explosives from the wellbore. Recently, we encountered an …

The Importance of Correct Pinning in Ball Drop Firing Heads

As a wireline engineer, the smallest detail can make all the difference between a smooth operation and a costly mistake. During one of our recent jobs, a routine TCP (Tubing Conveyed Perforation) operation took an unexpected turn due to issues with the ball drop firing head. What we thought was a simple misstep in the …

Lessons Learned from a Failing Firing Pin in Wireline Perforating

As a wireline engineer, there are moments that define your approach to safety, operations, and equipment maintenance. One such moment happened during a routine perforation operation, which turned into a valuable learning experience. It all started with a misrun during a TCP (Tubing Conveyed Perforation) operation on stage one. The firing pin failed to initiate …

The Critical Importance of Double-Checking Gunstrings in Wireline Operations

As a wireline engineer, there’s one lesson you quickly learn: the smallest oversight can lead to significant delays and operational hiccups. Whether you’re involved in wireline perforating, cased hole wireline services, or wireline logging, ensuring that every piece of equipment is properly set up before deployment is crucial. I want to share an experience from …

The Crucial Role of Measuring Head Maintenance in Wireline Operations

In wireline operations, every detail matters. The success of a job relies on the reliability of every tool and piece of equipment, from wireline control systems to perforating guns. One of the most important—but often overlooked—components is the measuring head. This device plays a crucial role in accurately measuring the depth of the wireline during …

How a Shorted Cable Head Led to Valuable Lessons in Wireline Operations

In the fast-paced world of wireline engineering, everything must be executed with precision. One misstep or failure to act quickly can lead to serious delays, affecting both safety and efficiency. Recently, during a routine pumpdown perforation job on the Henderson 6H well, our team faced an unexpected challenge: a shorted cable head that led to …

A Game-Changing Change in PSA and Quick Change Setup

As a wireline engineer, I’ve been through countless setups, tool changes, and adjustments on the job. Yet, sometimes, even a small change in the way we approach a procedure can make a world of difference in the efficiency and reliability of the operation. One such change occurred during a recent wireline job where we introduced …
