Risk ranking of Horizontal Directional Drilling (HDD) for gas and oil wells is a key criterion in the project feasibility, pricing and for introducing a risk management strategy that aims to reduce the number of failures in the installation phase and its negative consequences. HDD is currently widely used in drilling wells in Iran, but research in the area of identification and risks ranking of...

Horizontal directional drilling (HDD) is widely used in soil and rock engineering. In a variety of conditions, it is necessary to estimate the torque required for performing the reaming operation. Nevertheless, there is not presently a convenient method to accomplish this task. In this paper, to overcome this difficulty based on the basic concepts of rock engineering systems (RES), a model for ...

Nowadays we can observe a growing demand for installations of new gas pipelines in Europe. A large number them are installed using trenchless Horizontal Directional Drilling (HDD) technology. The aim this work was to develop and compare machine learning models dedicated risk assessment HDD projects. data from 133 projects eight countries the world were gathered, profiled, preprocessed. Three mo...

The drilling length is an important parameter in the process of horizontal directional drilling (HDD) exploration and recovery, but there has been a lack of accurate, automatically obtained statistics regarding this parameter. Herein, a technique for real-time HDD length detection and a management system based on the electromagnetic detection method with a microprocessor and two magnetoresistiv...

Downhole drilling motors or mud motors are frequently used during the oil and gas well construction, especially for construction of directional and horizontal segments. However, low operation life of the down hole drilling motors and high rate of wear in their working elements may constrain their application due to technical and economical disadvantageousness. In this work, a high-torque modula...

This article presents the horizontal directional drilling (HDD) as one of most suitable technique used to reduce impact on environment during submarine pipe and cable installation process, especially in coastal area shallow waters. HDD is a drill subsea tunnel or under other designated with goal pull facility through drilled underground tunnel. With development offshore natural gas wind industr...
