AUGUST 2018 • E&MJ 99 EQUIPMENT GALLERY The Lithium Industry and Chile's Role Author: Gustavo Lagos Cruz-Coke Professor Gustavo Lagos has been a direct witness as well as a permanent and meticulous chronicler of this enthralling history that today is at an inflection point. Lagos is –almost certainly– the Chilean professional who has most studied and written about the lithium resources of our country, their characteristics, opportunities and restrictions.

By using the lab to examine multiple drill cores from different holes and different depths, geologists can form estimates about a deposit, the company reported. The results can be analyzed on-site or on the other side of the globe. The solution won the Red Dot Industrial Design Award in 2017 and is described by Orexplore as the result of more than two decades of X-ray research, algorithm development and sensor technology. Coring Rods With Self-aligning Threads Boart Longyear launched XQ Wireline Cor- ing Rods for drilling and coring. The rods, having been tested at 30 exploration lo- cations, are proven to be stronger, last longer, and are easier to make and break than RQ rods, the company reported. Fea- turing self-aligning, double-start threads, the rod's joints engage without wedging or jamming, the company reported. They also nix box bulging. Thread design in- cludes a -20° reverse fl ank angle for greater load capacity. Hardening is added to the crest of the pin thread to ensure a hardness difference between pin and box. W-Wall tubing design reduces rod weight. A thicker mid-body and ends provide a uniform bend and outer wear distribution, reducing mid-body wear. W-Wall's inner diameter gives more space to allow drill- ing fl uid to pass by inner tube assemblies during wireline tripping. Separately, Boart Longyear intro- duced TruShot, a magnetic downhole survey tool that captures high-quality, 3D hole path data, the company re- ported. The tool is used to precisely determine azimuth and dip measurement to determine where the hole is located and from where the core is retrieved.
