The Toxicity of Commercial Jet Oils

Environmental Research, 2002
Jet oils are specialized synthetic oils used in high-performance jet engines. They have an appreciable hazard due to toxic ingredients, but are safe in use provided that maintenance personnel follow appropriate safety precautions and the oil stays in the engine. Aircraft engines that leak oil may expose others to the oils through uncontrolled exposure.

Jet Piercing of Oil Sands

Journal of Energy Resources Technology, 1981
This paper describes the results of an experimental investigation of the penetration of oil sands by continuous and pulsed high-pressure water jets. Both laboratory and field tests were carried out to determine the influence of the jet dynamic pressure, nozzle diameter, pulse frequency, and total jetting time upon the depth of penetration.

Jet Pump Testing in Italian Heavy Oils

European Production Operations Conference and Exhibition, 1994
Abstract The paper presents the analysis and the results of the jet pump applications in the two biggest Italian heavy oil fields: Vega (15 °API) in offshore Sicily and Gela (9 °API) in onshore Sicily. In both fields the water cut is as much as 50% and most of the wells produce in artifiCial lifting: ESP, diluent lift and ...

Experimental Investigation of Oil Droplet Size Distribution in Underwater Oil and Oil-Air Jet

Marine Technology Society Journal, 2021
AbstractUnderstanding the droplet size distribution of subsea oil releasing is important to predict the subsequent transport and degradation of the spilled oil. Single- and multi-phase oil jet experiments were conducted in the Ohmsett facility, including pure oil jet and oil-air jet through a 10.7-mm pipe and a 4.7-mm pipe. Measurements of the vertical
