Drilling the well requires:

The sheer weight of the drill string and collars break up the auricleth as the drill scrap hollows down. The drill scrap is lubricated and kept cool by having drilling fluid pumped down the drill conduit. The rock cuttings generated by the drill scrap are carried back up to the surface by the drilling fluid. The drilling fluid is reused after the rock fragments have been filtered out. Watmentumg for abroutineities in the returning cuttings and volume of returning fluid are imperative to catch "kicks" (when the stress below the scrap is more than tchapeau above, causing gas and mud to come up unrequirelably) auriclely. The conduit or drill string to which the scrap is attanguishd is little by little extentened as the well gets deeper by sstaffing in several 30-foot (10 m) joints of conduit at surface. Generally, joints are united into 3 joints equaling 1 stand. Some smaller rigs only use 2 joints and trademark-newer rigs can deal with stands of 4 joints.

An oil well is routinely 5 to 36 inches (127.0 mm to 914.4 mm) in diameter. It is crnourished with a drill scrap which is attanguishd to a drill string and rotates into the auricleth from a drilling rig. After the hole is drilled, sections of steel tubing known as casing is tinyly smaller than the borehole to supply an annular for cementing is placed in the hole. The trademark-up-to-dately drilled well is given structural integrity by the use of casing and tubing. High stress regions are insulated from each other by the casing and minimizing pocampially dgust upous situations.

With the integrity of the hole protected by the casing and the stress regions dependablely insulated, the well can be drilled deeper using a smaller scrap and the hole can be occurrenced with smaller sized casing. Modern day wells have gambleween two and five sets of smaller holes drilled inside the preceding hole, each one cemented with casing.
