Occipital Headache. Occipital headache is a type of headache that occurs in the back of the head, specifically at the base of the skull. It may be the cause of your headaches and neck pain. If you have a history of migraine, sometimes a headache in this area will provoke a migraine. The pain is usually a dull throbbing type of pain and if this occurs then it is a type of tension headache.
1 Drilling the well hole, installing the casing (a tubular lining that prevents the well hole from collapsing) and adding a well cap (a tight-fitting, vermin-proof top seal) typically costs $15-$30 per foot, or $1,500-$3,000 for a 100' deep well, and $6,000-$12,000 for a 400' well. This brings the typical total for drilling a well and setting up a private water delivery system to $3,500-$20,000 or more, but an especially deep and difficult well with a complex water system can cost $20,000-$50,000 or more, depending on depth, water yield and system complexity.
The average cost per well at each depth interval in the JAS reports (1976Â­2004) was used to create the drilling index, because the drilling process is essentially the same for oil, gas, and geothermal wells. A 17% inflation rate was assumed for preÂ­1976 index points.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.
