Measurement While Drilling Essay 2751 Words

MWD stands for Measurement While Drilling in the oil gas industry. The simplest way to describe MWD is to relate it to the measurements a pilot takes. A pilot needs to know the direction they are flying (North, South, East, or West), the angle they are flying at (up, down, or horizontal), and what type of skies they will be flying through ...

Barite Metaphysical Healing Properties

Barite is the main source of barium. Barite is thought to have been extensively used by the Native Americans in their religious practices. Apparently, the Natives used it to shape shift as well as to go from the physical world to the spiritual. Barite takes a wide variety of forms and occurs as blade, prismatic and often large tabular crystals.
