It was just another day in the field—another job, another toolstring, another set of well conditions that we had to work with. We were rigged up, and everything seemed good to go. But, as any seasoned wireline engineer knows, appearances can be deceiving. Before sending the toolstring downhole, I reached for my unit ohm meter—a …
I still remember the first time I had to use a cablehead disconnect tool in the field. It was one of those jobs where everything was running smoothly—until it wasn’t. We were running a wireline logging operation deep in the formation, gathering critical downhole data. The logging tools were performing as expected, the winch operator …
Wireline operations are all about precision, control, and safety. Whether you’re tripping in or out of a wellbore, cable speed is a crucial factor that can make or break a job—literally. Over the years, I’ve seen how exceeding safe speed limits can lead to costly failures, equipment damage, and dangerous situations. Let me share some …
If you’ve been in the wireline business for a while, you know that a solid cable-head connection is the backbone of any successful logging run. It’s one of those things that, when done right, goes unnoticed—but when done wrong, it can turn into a nightmare fast. Improperly seated cones, kinked armors, or a rushed re-head …
Wireline logging plays a vital role in understanding subsurface formations and optimizing wellsite operations. Achieving accuracy and reliability in this process requires adhering to a set of established practices that cover data acquisition, processing, and interpretation. Here’s a breakdown of key principles that every wireline engineer should know. Optimizing Data Acquisition Wireline logging begins with …
Cement Bond Logging (CBL) is an essential process in evaluating the integrity of the cement sheath and its bond to casing and formation. Proper practices in data acquisition, quality assurance, and analysis ensure accurate results, leading to better well integrity management. Here’s a breakdown of the general practices for CBL. Data Acquisition: Setting the Foundation …
Pump-down wireline operations demand precision and good practices, especially when handling the drum while running in hole and pumping down. A crucial component in this process is the AA valve (commonly referred to as the bypass valve), which acts as a safety mechanism during high-torque situations. However, improper use of the AA valve can lead …
