The average height of a normal drilling rig is about 125ft, which is equivalent to a 10 or 11 storey building or around two-fifths the size of the clock tower of Big Ben. If a well needs it, the next stage of testing is the perforation and hydraulic fracturing (fracking) of the well to release the shale gas.
As Figure 6.1 shows, the average costs of completed oil and gas wells for the depth intervals from 1,250 feet (380 m) to 19,999 feet (6,100 m) can be described as an exponential function of depth, that is: (6Â­3) where only two fitted parameters, a and b 1, are needed.owever, an example wellÂ­cost estimate was developed for a 2,500 m (8,200 ft) oil and gas well with casing diameters that are more representative of those used in oil and gas drilling (the comparison is shown in Table 6.2). These costs are within the scatter of the JAS cost information for California.
