The Rockwell Hardness test is a hardness measurement based on the net increase in depth of impression as a load is applied. Hardness has been variously defined as resistance to local penetration, scratching, machining, wear or abrasion, and yielding. The multiplicity of definitions, and corresponding multiplicity of hardness measuring instruments, together with the lack of …
Intentionally engineered electrical power outage caused due to lack of available resources (electricity) to meet demand during peak hours.
When mining an economic seam such as metal ores or coal, this is normally the rock left on the roof of the mine gallery
The complete operation of removing the drillstring from the wellbore and running it back in the hole. The operation is usually done when the bit becomes dull or broken and thus no longer drills the rock efficiently
The ratio of additions to reserves divided by production. It is a measure of the extent to which production is being replaced and is an important element of oil and gas companies’ portfolio. Reserve changes from all sources divided by total production for a given time period.
This is the amount of electricity capacity available in a country over and above consumption during peak hours. In Israel reserves (as of 2008) are about 5% which is extremely low, especially considering that consumption is growing annually at between 3-5%. Currently, IEC’s capacity stands at 11,300 MW
Amount of oil or gas in a reserve that can be produced. Generally reserves refer to the volume of technically and commercially recoverable hydrocarbons in an oil and/or gas reservoir (as opposed to the total volume of oil or gas in place, much of which may not be recoverable using current technology and in current …
Term used by international oil companies to describe a new trend by nation states, such as in the Middle East, Russia and in South America, by governments determined to keep full control of their petroleum resources and not to share profits, even at the expense of more efficient exploitation techniques and greater financial ability of …
Prices of oil have been rising due to several reasons: Supply issues with production declines in certain oil producing countries such as Mexico, an unstable oil industry in Venezuela and Nigeria and possible shrinking production capacity in the Middle East; a weak dollar and political instability in some oil-producing countries; a tight market due to …
There are two main types of onshore drilling for natural gas. Rotary drilling consists of a sharp, rotating metal bit used to drill through the Earth’s crust. The drill bit is connected to and rotated by a drill stem, which also provides a passageway through which the drilling fluid (mud usually) is circulated. This type …
