With modern synthetic oils and new tests such as BMW's LL ("long life") oil specifications, most current cars can go over 6,000 miles (9,700 km) before needing an oil change. Even most modern conventional oils (also called mineral oils) can take a car engine at least 5,000 miles (8,000 km) before needing an oil change. [1] [2] [3] [4]
Water capacitors are not widely used in the industrial community due to their large physical size for a given capacitance. The conductivity of water can change very quickly and is unpredictable if left open to atmosphere. Many variables such as temperature, pH levels, and salinity have been shown to alter conductivity in water. As a result ...
The system will then gauge the oil concentration based on a light intensity meter. Modern oil content meters also have a data logging system that can store oil concentration measurements for more than 18 months. [2] Oil content meter. If the OCM determines that there is far too much of a type of oil, the OCM may be fouled and needs to be ...

A shale gas well being drilled by a drilling rig in Pennsylvania. Produced water is a term used in the oil industry or geothermal industry to describe water that is produced as a byproduct during the extraction of oil and natural gas, [1] or used as a medium for heat extraction.
The oil and the oil filter need to be periodically replaced; the process is called an oil change. While there is an entire industry surrounding regular oil changes and maintenance, an oil change is a relatively simple car maintenance operation that many car owners can do themselves.
The cleaning can be done by running fresh water through the OCM via a permanent connection or can be performed by opening the OCM sample area and scrubbing the sample area with a bottle brush. [4] The water removed by the OWS flows to oil collecting spaces. There can be two stages.
In most situations in the hydrocarbon industry the term is qualified as being an oil-water contact (abbreviated to "OWC") or a gas-water contact ("GWC"). Often there is also a gas-oil contact ("GOC"). [2] In an oil or gas field, hydrocarbons migrate into rocks and can be trapped if there is a permeability barrier to prevent upward escape. Gas ...
