This paper presents how to model technical and human errors and how the two error types are integrated in one common model. Human errors were modeled as an integral part of the organization’s ability to handle failures, while technical errors were embedded as an integral part of the oil well drilling operation. To reduce the number of offshore accidents there is a continuous focus on safety imp...

The base fluids of eco-friendly cutting should contain some vegetable oil. Due to their eco-friendly, thermal, and tribological qualities, these types machining are becoming increasingly popular among researchers throughout the world. authors summarized published research studies on use (including nanofluids) in various metal removal processes such as turning, milling, grinding, drilling this r...

Gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), supercritical fluid chromatography (SFC), elemental analysis, infrared absorption spectroscopy (IR), thermal analysis (TG/DTA), Rock-Eval pyrolysis, as well as viscosity and density analysis revealed that oil sands from Qaidam basin, Qinghai Province of China, are highly concentrated in light components (£C23), with saturate...

Oil and gas well drilling activities are associated with numerous hazards which have the potential to cause injury or harm for people, property and the environment. These hazards are also a threat for the reputation of drilling companies. To prevent accidents and undesired events in drilling operations it is essential to identify, evaluate, assess and control the attendant risks. In this work, ...

Oil well drilling is a complex process which frequently is leading to operational problems. The process generates huge amounts of data. In order to deal with the complexity of the problems addressed, and the large number of parameters involved, our approach extends a pure case-based reasoning method with reasoning within a model of general domain knowledge. The general knowledge makes the syste...

Abstract In this study, the direct intercalation of gemini ionic liquids (ILs) with different alkyl chains into bentonite (BT) interlayer as a high-performance lubricating additive for base oil 500SN was investigated. The purpose modifying BT an IL is to improve dispersion stability and lubricity in oil. dispersibility tribological properties IL—BT oil-based additives depend on increase interla...
