In the world of wireline well logging, the performance and longevity of cables are critical to operational success. I’ve seen firsthand how improper cable handling leads to premature failures, resulting in costly downhole pipe recovery operations and lost time. Proper cable care and use are essential for ensuring efficient cased hole logging and extending equipment …
Every wireline engineer knows that consistency, accuracy, and safety are the backbone of successful wireline well logging and cased hole logging operations. One misstep can lead to downhole tool failure, pipe recovery operations, or even catastrophic well integrity issues. That’s why having well-documented Standard Operating Procedures (SOPs) is essential in wireline services oil and gas. …
In wireline well logging, every tool run must be controlled carefully, especially during pulling out of hole (POOH) operations. I recall a time when an operator failed to engage the tool trap at the right moment. The result? The tool unexpectedly slipped downhole, causing delays, risking downhole tool loss, and leading to an unplanned pipe …
During a routine wireline perforating job, I witnessed a cable head failure mid-operation. The issue? Corrosion had weakened the internal structure, leading to a premature break. This incident reinforced the importance of proper cable head maintenance, especially when dealing with corrosive wellbore fluids. One of the most effective ways to extend the life of cable …
Every wireline service provider knows that a weak connection in the cable head can mean the difference between a successful job and a costly failure. I once encountered an issue during a cased hole well services operation where the cable head failed under load far below its expected breaking strength. The culprit? A mismatched brass …
A Costly Depth Discrepancy in Wireline Logging A simple oversight can derail an entire wireline well logging job. I once worked on a project where a depth discrepancy caused major confusion. The logs were misaligned, and after a thorough investigation, the root cause was identified: the GEO-LOG measuring wheel had the incorrect rim size for …
When Wireline Length Becomes a Costly Oversight A wireline job is only as successful as its planning. I once arrived at a wellsite only to realize that the wireline unit did not have enough logging cable to reach total depth. The unit had to be replaced, costing valuable time and undermining the customer’s confidence. It …
In wireline and perforating operations, handling explosive devices is a critical aspect of maintaining well integrity and ensuring safe perforation well execution. I once witnessed an incident where a worker attempted to remove a port plug from a switch sub, unaware of the trapped pressure inside. The force of the ejected plug caused serious injury. …
During a routine gamma gun operation, an unintentional detonation occurred—an alarming moment that could have led to severe consequences. It all started when the power control box was enabled, and within seconds, the plug set out of zone unexpectedly. A thorough investigation into the wireline control systems revealed that a few overlooked settings led to …
In wireline and perforating operations, the selection of the correct detonating cord is crucial for ensuring consistent detonation transfer and safe perforation well execution. I recall a job where improper cord selection led to a misfire, forcing us to troubleshoot a failed wireline perforating gun. That experience reinforced the importance of understanding how different types …
