There’s a moment in every wireline job when everything either comes together—or comes apart. On this particular cased hole wireline operation, it was a pumpdown job in a tight horizontal well, and it reminded me why wireline logging isn’t just a technical skill—it’s a discipline forged by precision, pressure, and practice. We were assigned a …
Some wireline jobs teach you about the well. Others teach you about yourself. But this one? It taught me the importance of knowing your tools inside and out—especially when those tools can make the difference between a successful perforation well and a dangerous misfire. We were gearing up for a standard cased hole logging run—wireline …
There’s something about the rhythm of a wireline job—the calm before arming the panel, the measured current readings, the sharp focus right before firing. You learn to trust your training, your team, and most importantly, your tools. This story takes me back to a cased hole logging operation where the Dyna and Multitronic systems reminded …
The crane isn’t the first thing most people think about when they talk wireline logging. Most attention goes to the logging cable, the perforating gun, or the downhole sensors used in formation evaluation. But if you’ve been out on enough cased hole logging jobs—especially in the high-stakes world of wireline and perforating—you know that without …
They say every tool tells a story—if you know how to read it. For me, one of the most underrated tools in the wireline logging arsenal is the Casing Collar Locator, or CCL. It’s not flashy like a perforating gun, and it doesn’t give you beautiful caliper log curves or deep formation evaluation insights. But …
It was one of those long days on location—hot, dusty, and behind schedule. We had a cased hole logging job to run: standard CBL log, some production logging, and maybe a perforation service request depending on what the logs showed. Everything was in place. The wireline truck was ready, the wireline control systems fired up, …
Some lessons in the field hit you hard—not because the job went wrong, but because it went exactly the way it could have if you didn’t know what you were doing. We were prepping for a standard cased hole logging run. The tools were rigged up, the wireline truck powered, and the logging cable coiled …
I still remember that shift like it was yesterday. We were working a deep vertical well, pushing down past 12,000 feet. The job was straightforward: run a standard cement bond log (CBL) and variable density log (VDL) to evaluate the cement integrity. Simple enough, right? But anyone in wireline logging knows—there’s no such thing as …
We were working a deep lateral out in the basin. The frac crew was moving fast, everything running smooth on a cased hole wireline job. My team was setting up for a wireline perforating run, and I requested the base log depth to tie into. The client handed me the numbers from a previous crew—looked …
There’s one rule I never let my crew forget: never start prepping a setting tool unless you can finish it in one go. That rule didn’t come from theory. It came from experience—specifically, a hectic cased hole wireline job where an operator was pulled away mid-prep. The tool ended up with mismatched explosives and a …
