Studying Effects of Cooling/Lubricating Fluids, Machining Parameters, and Rock Mechanical Properties on Specific Energy in Rock Drilling Process

Shahrokh Khosravimanesh; Masoud Cheraghi Seifabad; Reza Mikaeil; Raheb Bagherpour

Volume 15, Issue 2 , April 2024, , Pages 613-636


  Specific energy is a key indicator of drilling performance to consider in the feasibility and economic analyses of drilling projects. Any improvement in the specific energy of a drilling operation may reflect an improvement in the overall efficiency of drilling operations. This improvement can be achieved ...  Read More

Improvement of Drill Bit-Button Performance and Efficiency during Drilling: an application of LSTM Model to Nigeria Southwest Mines

Babatunde Adebayo; Blessing Olamide Taiwo; BUSUYI THOMAS AFENI; Aderoju Oluwadolapo Raymond; Joshua Oluwaseyi Faluyi

Volume 14, Issue 4 , October 2023, , Pages 1121-1139


  The quarry operators and managers are having a running battle in determining with precision the rate of deterioration of the button of the drill bit as well as its consumption. Therefore, this study is set to find the best-performing model for predicting the drill bit button's wear rate during rock drilling. ...  Read More

Rate of Penetration Prediction in Drilling Operation in Oil and Gas Wells by K-nearest Neighbors and Multi-layer Perceptron Algorithms

Yahia ElSayed Khamis; Shady Galal El-Rammah; Adel M Salem

Volume 14, Issue 3 , July 2023, , Pages 755-770


  The rate of penetration plays a key role in maximizing drilling efficiency, so it is essential for the drilling process optimization and management. Traditional mathematical models have been used with some success to predict the rate of penetration in drilling. Due to the high complexity and non-linear ...  Read More

Study of Effect of Cooling/Lubricating Fluids, Machining Parameters, and Rock Mechanical Properties on Penetration Rate in Rock Drilling Process

Sh. Khosravimanesh; M. Cheraghi Seifabad; R. Mikaeil; R. Bagherpour

Volume 12, Issue 3 , July 2021, , Pages 825-843


  In most rock drilling operations, the low rate of penetration (ROP) can be primarily attributed to the presence of the cuttings produced during drilling and the thermal stresses caused by friction at the bit-rock interface, which can be exacerbated with the increasing strength, hardness, and abrasivity ...  Read More

3D model construction of induced polarization and resistivity data with quantifying uncertainties using geostatistical methods and drilling (Case study: Madan Bozorg, Iran)

K. Mostafaei; H. R. Ramazi

Volume 9, Issue 4 , October 2018, , Pages 857-872


  Madan Bozorg is an active copper mine located in NE Iran, which is a part of the very wide copper mineralization zone named Miami-Sabzevar copper belt. The main goal of this research work is the 3D model construction of the induced polarization (IP) and resistivity (Rs) data with quantifying the uncertainties ...  Read More
