The Drillers Club The drillfloor with its  associated equipment is designed for sole purposes of drilling and if productive completing oil or gas wells, a well designed drillfloor should have a simple layout with plenty of working space. The Drill Floor is the heart of  drilling rig and is also referred to as the Rig Floor. It is here where the drill string and drilling bit, and various other tools are connected together and tested before its trip into the hole. When drilling, the tools used are made up as the  BHA (Bottom Hole Assemble) and transported into the hole using a drill string, (Drill Pipe) however once on bottom the BHA can be dived into two sections, a), to apply weight to the drill bit, the weight applied to the bit is a proportion of the weight that is made up from the drill collars that are picked up to form the BHA, The BHA can consist of many tools and subs, most are installed in the lower 90 feet and are spaced out using drill collars, other drill collars and Heavy weight drill pipe are installed that maybe used to add weight to the bit or: b). to keep the drill string in tension , traditionally the drill string is made up of drill pipe and once picked up will be run into the hole in stands,  one stand of drill pipe is normally 3 joints of pipe of an average length of 31.2 feet, hence an average stand would be 93 +/- feet Why make the drill string up into stand, the truth is that no drill bit or tool will last forever, therefore once the bit or tool is dull it will have to be removed from the well and a new one run back in, to do this the string has to be pulled from the hole (tripped) the pipe is racked back as stands The stands are stored in the set back area of the rig floor and held in place by the finger board mounted 85 feet up in the derrick
