Metalworking fluid emulsion formulations produced from vegetable oils may be less toxic and may reduce disposal costs when compared with fluids formulated with petroleum-based oils. Experiments were performed on experimental emulsions made with unmodified and modified soybean oils to measure rates of mist production by impaction, centrifugal force and evaporation/recondensation mechanisms. Resu...

The porosity and methane adsorption capacity of shale used to estimate gas in place (GIP) are affected both by moisture oil residing the pore structure, as well naturally present from maturation, which can include contaminant drilling mud fluids for drilling. To demonstrate impact extractable on dry moisture-equilibrated shales, two overmature shales China (SH1, SH2) lower mature UK (BS3, GH4) ...

With the introduction of nanotechnology, energy industries envisage a potential revolutionary change in the field of exploration, development and production. Research by universities into such areas as nanosensors, nanomarkers and nanobots to provide valuable data regarding the reservoir are of great focus due to their large potential return on investment, but have yet to yield substantive prod...

Taking into account the need for post-war reconstruction of country’s infrastructure, development high-quality drilling fluids based on Ukrainian mineral raw materials becomes a particularly urgent problem. Detailed studies rheological properties aqueous dispersions Na+-bentonite from Cherkasky deposit (Ukraine) were carried out in relation to horizontal directional drilling. The effect pH, ion...

This study proposes a methodology to diagnose the root causes of failures in the domain of oil well drilling. The idea is to combine a Bayesian network, which is generated based on an expert knowledge, with situation-specific knowledge of past failure cases. A causal chain is viewed as a temporal sequence. To test the model’s capability, six failure cases from the study’s application domain (oi...

The implementation of sustainable manufacturing techniques to make machining operations more eco-friendly is a demanding issue that has gained attention from academic and industrial sectors. In some operations, large quantity fluids wasted easier, especially during the difficult-to-machine materials such as stainless steel. circumstances, many researchers are investigating techniques. Therefore...

[1] Integrated Ocean Drilling Program (IODP) Hole 1301A was drilled, cased, and instrumented with a long‐term, subseafloor observatory (CORK) on the eastern flank of the Juan de Fuca Ridge in summer 2004. This borehole is located 1 km south of ODP Hole 1026B and 5 km north of Baby Bare outcrop. Hole 1301A penetrates 262 m of sediment and 108 m of the uppermost 3.5 Ma basaltic basement in an are...
