The equipment for processing the water for the drilling operations is shown in Figure 2 and also includes a plate and frame filtration device for removing drill solids. In some application, the water can be returned to the drilling operation at high TDS without the problem. The air drilling rigs are used to drill down to the lateral sections in the shale fracturing because of the speed the wellbore can be drilled. This appears to be the most profitable use of the method.
