With the GEO-MRI | NMR @ Borehole Logging Operation: "The fun is over!"

All of a sudden it went really fast, and "fun" quickly turned into "serious!":

On ultra-short notice: Sent with the NMR truck from Seattle through snow and rain, over mountains and wide, long country roads to Salt Lake City for the first "real" NMR borehole logging mission. Bring it on!

In Salt Lake City: Picking up our colleague and NMR-top-professional Dr. Warren Caldwell (PhD @ Stanford | since 6 years at Vista Clara Inc.) at the airport, and off we went!

The actual measurement mission was in support of a well construction (about 400 meters deep) to use NMR-technology for the identification of sand/clay sequences in the strata sequences and to qualitatively and quantitatively estimate the potential production effectiveness of the new well as a function of depth.

After assembling the probes, the instrument string was adjusted, centered, and lowered over the wellbore to take NMR measurements to the maximum depth of 400 m.

Teamwork in the Salt Lake City, Utah region: with Vista-Clara Inc. colleague Dr. Warren Caldwell for NMR borehole logging. Objective: Identification | verification of aquifers (sand) | non-acquifers (clay) to support the construction of a new well for groundwater supply to regional communities. Additional active support was willingly provided by the young colleagues of DGI (this geophysical company specializes in acoustic and optical borehole logging systems, but also offers other logging services and measurement methods).

That was the plan - and of course it went wrong at first! There was no way through after just 20 meters of borehole depth. So what to do?

After a few unsuccessful attempts, it was decided to clean/ream the borehole again properly and then to try again early the next morning. And lo and behold: everything went like "Swiss Clockwork"!

After some extra effort, it all worked out well in the end - thanks to the excellent team work by Vista-Clara Inc. nd DGI teams, plus the "Kings of Site": the drillers. And, of course, due to the correct decisions by the boss @ site (with LRE).

Thus, the challenge of the long journey and the initial difficulties with the measurement were finally turned into a successful borehole logging campaign under the competent guidance of Dr. Caldwell - not without with the energetic cooperation of two young colleagues from the partner geophysics company DGI, plus, of course,, with the superb work of | support by the "Kings of the Well Site": The Drillers. All super guys, top teamwork, and a very appealing end result!

That's the way to go! Also as a positive work experience and example for our next project that is already waiting for us: NMR-Well-Logging in Peru.

"Carpe Diem/Good luck!"
