The optimization of drilling operations is an ongoing necessity since the major proportion of
the terrestrial hydrocarbon reservoirs has been exhausted. Furthermore, there is a growing …

Drilling problems such as stick slip vibration/hole cleaning, pipe failures, loss of circulation,
BHA whirl, stuck pipe incidents, excessive torque and drag, low ROP, bit wear, formation …

This paper introduces a review of the modern approaches of digitalization in the oil and gas
industry. The objective is understanding the current applications of the traditional …

Inspired by the fourth industrial revolution (4IR) and digital transformation (DT), the Internet-
of-Things (IoT) and artificial intelligence (AI) have become valuable tools in the oil/gas …

Optimization, digitalization and robotization of oil and gas technological processes based on
the use of artificial intelligence methods are among the prevailing trends of the 21st century …

Drilling fluid property characterization currently involves several manually executed
analytical tests, conducted in accordance with American Petroleum Institute (API) …

On a land‐based rig, the driller has many responsibilities and is rarely able to adjust the
main process controls—weight on bit (WOB) and revolutions per minute (RPM)—on a …

During recent years there has been an increased focus on automating drilling operations
and several solutions are in daily use. We describe here results and lessons learned from …

An algorithm for regulation of the vertical penetration rate in rotary drilling systems is
developed under the assumption that parameters of the rock-bit interaction as well as those …

The drilling process is complex because unexpected situations may occur at any time.
Furthermore, the drilling system is extremely long and slender, therefore prone to vibrations …
