Embedded sensors, connected to the industrial internet of things (IIoT), have increased the granularity and frequency of data collected during the drilling process – but the data is often siloed and underutilized. This lack of integration can lead to expensive, time-consuming problems during the drilling process. Inefficient drilling programs can have an even greater aggregate financial impact,...

vibratory drilling (vd)process is a new modern technology where longitudinal wave with high frequency (more than 16 khz) and low amplitude (usually between 2 up to 30 µm) is superimposed on the movement of cutting tool, resulting in connection and disconnection of cutting tool engagement with workpiece. in this study, in order to perform vibratory drilling process, two vibration tools are desig...

When developing coal and ore deposits by underground method, it is necessary to carry out a large volume of preparatory mine workings using drilling blasting operations. Minerals are found in rocks under various conditions their physical mechanical properties change wide range. Under such conditions, use machines this different the principle action structural features. The article considers geo...

control of well drilling operations poses a challenging issue to be tackled. the loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. conventional proportional-integral (pi) controller is a common practice in the well control operation. the small existing margin between pore pressure and f...

Multiplicity of the effective factors in drilling reflects the complexity of the interaction between rock mass and drilling bit, which is followed by the dependence of parameters and non-linear relationships between them. Rock mass or, in other words, the formation intended for drilling, as the drilling environment, plays a very essential role in the drilling speed, depreciation of drilling bit...
