Unit of kinematic viscosity equal to 1/100 stoke
Unit of viscosity. It is the amount of force needed to move a layer of liquid in relation to another liquid. Equal to 1/100 of a poise
65 million years ago to today
The earliest geochronological age, or geological age. First of six main divisions in ascending order in the upper cretaceous series representing rocks deposited worldwide during the Cenomanian age which occurred 99.6 to 93.5 million of years ago during the Cretaceous period. Rocks of the Cenomian stage overlie those of the Albian stage and underlie rocks of the Turonian. Rocks from this period are very abundant in Israel, in the Galilee, in the North of the Negev in proximity to the Dead Sea and in the Eilot region and include marine sedimentary rocks which is proof that these regions were covered in water at a certain period.
The application of a liquid slurry of cement and water to various points inside or outside the casing
Powder consisting of alumina, silica, lime, and other substances that hardens when mixed with water. Extensively used in the oil industry to bond casing to the walls of the wellbore.
Conventional ethanol and cellulosic ethanol are the same product, but are produced utilizing different feedstocks and processes. However, while conventional ethanol is derived from grains such as corn and wheat or soybeans cellulosic ethanol can be produced from a wide variety of cellulosic biomass feedstocks including agricultural plant wastes (corn stover, cereal straws, sugarcane bagasse), plant wastes from industrial processes (sawdust, paper pulp) and energy crops grown specifically for fuel production, such as switchgrass. While grain based ethanol utilizes fossil fuels to produce heat during the conversion process, generating substantial greenhouse gas emissions. Cellulosic ethanol production substitutes biomass for fossil fuels.
Pieces of rock that come from the wellbore but were not removed directly by the drill bit
The science of cathodic protection was born in 1824 with Sir Humphrey Davy who after an investigation concerning the rapid decay of the copper sheeting on His Majesty’s ships of war found that electrochemical science offered an important application and enabled Davy to succeed in protecting copper against corrosion from seawater by the use of iron anodes
