If there’s one thing wireline perforating teaches you, it’s that every component in a perforation job must be perfect. A misfire, a failed detonation, or an unintended event can cost time, money, and, most importantly, safety. One day, we almost ran a recalled A-140S blasting cap into the hole—a mistake that could have led to …
In wireline perforating, precision is everything. Whether you’re setting up perforating guns for cased hole wireline or running pump down perforating operations, one small mistake can mean a failed detonation—or worse, an unintended one. I learned this the hard way during a critical well perforation job. The Setup: A Routine Perforating Run We were preparing …
There are two types of lessons in wireline engineering—the ones you learn in training, and the ones the field teaches you the hard way. This story is about one of the latter. The Setup: A Routine Plug Setting Job It was supposed to be a straightforward plug setting operation. We were using a Baker wireline …
One thing about wireline engineering—just when you think you’ve seen it all, the oilfield throws you a curveball. This story takes place during a pressure test for a PWP tool, something that should have been routine. Instead, it turned into a lesson in bottom hole pressure (BHP) calculations, sensor calibration, and troubleshooting telemetry issues. The …
Perforating is one of those wireline operations where precision meets high risk. Whether it’s pump down perforating, cased hole perforation, or plug and perf, one wrong move can mean costly misfires—or worse, an unintentional detonation. I remember one job where a simple wiring oversight nearly turned into a disaster. The Setup: Standard Perforating Run It …
Every wireline engineer knows that cased hole logging is more than just a job—it’s an exercise in precision, patience, and sometimes, pure problem-solving. I learned this the hard way during a caliper log job that started as routine but quickly turned into one of my most memorable downhole diagnostics experiences. Setting Up for Success (Or …
There are two kinds of days in wireline services oil and gas—the ones where everything goes smoothly, and the ones that remind you why pressure control is critical. This story takes place on one of those second kind of days. The job was simple: run a cased hole logging operation to assess casing integrity before …
