Sonic is an advanced method of drilling which uses a high-frequency energy known as an oscillation that is generated inside the Sonic head. During drilling, the high-frequency oscillation is transferred down the drill string to the bit face at various Sonic frequencies (0hz to 150hz). Simultaneously rotating the drill string (Max 90rpm) evenly distributes the energy and impact ...

Barge drilling in tidal ports is a challenging task, but it is one that requires teamwork and perseverance. In this story, we will follow the crew of a barge drilling rig as they work to drill 12 holes in two different ports in Africa, 350 kilometres apart.The crew faced a number of challenges, including: Tidal ports: The tides and large swells can make it difficult to maint ...

We have a deep love for animals in need of shelter, a home and love. It's because of this that we chose to help PETS Jhb for our 67 minutes of change.PETS (Pet Empowerment ...

Electronic Vane Shear Testing (eVST) is a widely used method for measuring the undrained shear strength and remoulded shear strength of soil. This technique involves pushing the apparatus into the soil and rotating it, using an electronic motor situated above the vanes, at a controlled rate while measuring the torque required to cause shear failure. eVST is a quick, easy, and n ...
