Shale Oil: Definition, Production, Fracking, Pros, Cons

 · Shale oil extraction methods are more flexible than traditional oil well drilling. The initial drilling only accounts for 40% of the total cost. Extracting the oil costs roughly $1 million for each well. That made shale oil extraction profitable when oil reached $100 a barrel.

We recommend that you check the oil level in the morning when the engine is cold and most of the oil has run down into the engine’s oil pan. The oil pan forms the bottom of your engine and is the reservoir for the engine oil. You will need a clean cloth or paper towels , a can of oil and a funnel. We also recommend wearing disposable gloves.

Why an Oil's Viscosity Drops

For instance, if you are using an ISO 220 viscosity gear oil but a lower viscosity gear oil (such as ISO 68) of the same brand is added in, this can lead to a sudden drop in the viscosity reading when the oil is sampled. A decrease in viscosity may also occur when non-lubricants like solvents and diesel fuel accidently get into the lubricant ...

Tetraethyllead

Tetraethyllead (commonly styled tetraethyl lead), abbreviated TEL, is an organolead compound with the formula (CH 3 CH 2) 4 Pb.. TEL is a petro-fuel additive, first being mixed with gasoline (petrol) beginning in the 1920s as a patented octane rating booster that allowed engine compression to be raised substantially. This in turn caused increased vehicle performance and fuel economy.

The Oil Drum | Tech Talk

 · The original Prudhoe is a small village with a medieval castle on the south bank of the Tyne, in the northeast of England. It lies in a coal-mining region within five miles of Prudhoe Colliery, where there were, over time, an additional 157 mines and pits and five working seams of coal in the 1860s. Not in itself out of the ordinary, but by 1828 Prudhoe had given its name to a region in Alaska.

How Long Should Heating Oil Last, and How Much Will I Use?

For example, if trace elements of metal and rust get into the oil, it will corrupt the viscosity and make it more difficult for the oil to work its way through the heating system. If the problem is allowed to fester, the bad oil can hamper system efficiency and force moving metal parts to grind against one another, causing corrosion in the process.
