Hydraulic jars for slickline are generally meant to jar up only, because not enough sinker bar is able to feasibly be lubricated in to jar down on the downhole tools. Hydraulic jars work by the operator pulling up on the line, which puts an upward force on the top of the hydraulic jars.
Silicon was discovered by Joens JÃ¶ns Jacob, berzelius A swedish, chemist in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual-by. Products silicon is the seventh most abundant element in the universe and the second most abundant element in the'earth s. crust
Silicon is manufactured through the process of Mettalurgical Grade Silicon, where by silicon is derived from silica through several manufacturing processes. Substances: silica, wood, charcoal and few other substances, have been placed in a furnace. The reactants are heated at high temperatures, until carbon electrodes reduce silica to form silicon.
