The rate of penetration (ROP) is one of the vital parameters which directly affects the drilling time and costs. There are various parameters that influence the drilling rate; they include weight on bit, rotational speed, mud weight, bit type, formation type, and bit hydraulic. Several approaches, including mathematical models and artificial intelligence have been proposed to predict the rate o...

Isolated carbon nanotubes (CNTs), CNT films and CNT-polymer nanocomposites are a new generation of materials with outstanding mechanical, thermal, electrical and electromagnetic properties. The main objective of this article is to provide a comprehensive review on the investigations performed in the field of characterizing electrical and electromagnetic properties of isolated CNTs and CNT-reinf...

This paper is focused on minimization of the burr height and Tool wear in drilling of Aluminium Metal Matrix Composites(AMMC) using “Desirable-Fuzzy” approach, which is developed by combining the Desirability Function Analysis and Fuzzy Logic. AMMC samples are prepared based on selected material parameters and drilling experiments are conducted on these samples as per Taguchi OA L27 which is de...

Abstract The prediction of the drilling rate penetration (ROP) is one key aspects optimization due to its significant role in reducing expensive costs. Many variables could affect ROP, which can be classified into two general categories; controllable operational and uncontrollable or environmental variables. Minimizing cost achieved through optimizing parameters. As a direct result, speed will ...

The problem of slow drilling in deep shale formations occurs worldwide causing significant expenses to the oil industry. Bit balling which is widely considered as the main cause of poor bit performance in shales, especially deep shales, is being drilled with water-based mud. Therefore, efforts have been made to develop a model to diagnose drilling effectivity. Hence, we arrived at graphical cor...
