The present invention generally relates to the field of an arrangement for enabling well drilling and developing. The invention, particularly relates to an arrangement for enabling well developing using water pressure systems.
Completing an environmental well requires three steps, drilling, development and pumping. The importance of “well development” is an integral part of the drilling process which can add significantly to the capacity of the finished well. There are mainly five types of well development techniques: (i) chemical; (ii) washing and backwashing; (iii) mechanical surging; (iv) air development; and (v) jetting. Several techniques for the air development of wells exist. However, all inject air into the borehole such that aerated slugs of water are lifted irregularly out the top of the well casing. Air pressure may be cycled on and off to create a surging action desirable in well development. Sufficient air pressure will result in a continuous flow of aerated water out the top of the well, removing sediment and fine particles from the borehole. For small wells, air may be injected down the drill step into the formation. For larger diameter wells a separate airline and eductor pipe are inserted into the borehole. The size of eductor pipe and airline depend on air pressures and volume available as well as casing diameter. Even so air as a development is probably the most popular and widely used method of well development today.
Typically, wells (i.e., water, in-situ, gas, etc.) are completed by inserting a casing (e.g., steel or PVC) into the well bore extending into the earth. This well bore casing may be secured within the well bore by packing a permeable material, such as gravel, between the casing and the well bore. In this instance, the casing may include perforations in the section of the well bore that passes through a permeable formation of interest (e.g., an aquifer or coalbed). The perforated casing allows a fluid of interest (e.g., water or gas) within the permeable formation to permeate into the well bore where it may be extracted.
A number of different types of accessories and methods for well drilling and developing are available in prior art. For example, the following patents, which are herein incorporated by reference for their supportive teachings, are provided for their supportive teachings and all are incorporated here by reference:
U.S. Pat. No. 2,595,126 discloses a well drilling machine which comprises relatively vertically adjustable inner and outer drilling units operative to cut or dig the central portion and edge or wall portion, respectively, of the well bore; such drilling units being so adjustable in order to permit one unit to first Work ahead of the other and then retract for operation of the later.
U.S. Pat. No. 4,182,418 discloses a tool for perforating water well pipe casings. The tool is designed for use with air rotary water well drilling apparatus. The tool includes a slideable casing perforator wheel actuated by a pneumatic cylinder carried within the tool. The casing may be perforated and subsequent development of the well carried out while the tool is in place. No removal is necessary to carry out well development.
U.S. Pat. No. 3,612,177 discloses a complete system for developing underwater hydrocarbon fields which utilizes a floating topside facility, a template fixed to the submarine terrain below the topside facility, and a composite riser interconnecting the template and the topside facility.
US patent application no. US20090133929 discloses a machine for ground drilling, with a circulating fluid, by the utilization of electric discharge generated by high-voltage pulses between electrodes.
U.S. Pat. No. 5,069,285 discloses well development tool particularly useful in medium size wells has a suction head or a development head which may be fitted to an eduction pipe. The eduction pipe is made from serially connectible double walled pipe sections with an inner conduit surrounded by a coaxial outer conduit. The outer conduit of each section extends beyond the inner conduit. The outer conduit is threaded on each end so that a removable slip connector joins the inner conduits of adjacent pipe sections when the outer conduits are screwed together. The eduction pipe has an eduction nozzle for redirecting fluid from the outer conduit upwardly into the inner conduit to create an eduction effect in the inner conduit for drawing well fluid upwardly out of the well.
U.S. Pat. No. 4,185,703 discloses an apparatus for production of very deep boreholes. A rotary drilling tool is suspended at one end of a very long line of supporting elements such as a cable. During at least the entire duration of the drilling operation, the borehole is filled at least partly with at least one substance which remains in a liquid state and has a density greater than the mean density of the drilled ground strata. Thus any infiltrations in the borehole and the drilling debris move naturally upwards to the free surface of the liquid substance filling the borehole. In another prior art non-patent literature document, author Annderson K. discloses use of a compressed air for well drilling and development. The compressed air can be injected into the well to lift the water; As it reaches the top of the casing, the air supply is shut off, allowing the aerated water column to fall (process called “rawhiding”). The air supply should be periodically run without stopping to pump sediment from the well (see: Anderson, K. (1993) Ground Water Handbook, Dublin Ohio: National Ground water Assoc.—http://www.lifewater.ca/drill_manual/Section_10.htm). Another non-patent literature prior art document discloses a method of well drilling by using just one hose. The method includes the step of pumping both water and air down to the bottom of the hole. The water and air mixture then bring the cuttings to the top inside the drill pipe (see: http://www.drillyourownwell.com/one-hose-well-drilling.htm).
Many different techniques, such as over-pumping, chemical method, backwashing, jetting, surging, compressed air, bailer, surge block, etc. are also explained in the prior art documents. Air surging and air pumping technology is quite commonly used in water well developing. In air pumping technology, air hose fittings are blowing back out when the device reach to the 100 ft. Further, if the device reach to the 200 ft down it becomes very difficult to use air hose fitting.
Further, above mentioned references and many other similar references has one or more of the following shortcomings: (a) consuming more time; (b) complex tools; (c) requirement of more human resources to handle the equipment; (d) requirement of the more supplies; (e) expensive; and (f) use of drill rig during the well development.
The present application addresses the above mentioned concerns and short comings with regard to providing an arrangement for enabling well developing efficiently and easily with minimum human resources.
In the view of the foregoing disadvantages inherent in the known types of accessories and methods for well developing now present in the prior art, the present invention provides an arrangement for enabling well developing.

The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
In many types of well drilling and well developing operations well casing is punctured at points below the ground and the openings thus formed must be cleared. In the drilling of water wells, for example, it is common practice to drive the well casing to a desired depth, at or beyond water bearing strata, and then to perforate the casing within the upper and lower boundaries of water bearing strata to provide for flow of water into the well casing. After perforation of the well casing, the well must be developed, that is, sand and other debris must be driven from the casing perforations and such debris and other particles must be driven from the interior of the casing. Commonly after completion of the perforation the perforating tool is withdrawn from the well and an air-jet nozzle is then positioned within the well to accomplish well development. “Well development” includes those steps in completing a water well that aim to remove the finer materials from the aquifer, thereby cleaning out, opening up, or enlarging passages in the formations so that water can enter the well more freely. Whether the well has been drilled in an unconsolidated aquifer or in a hard rock formation, the drilling inevitably reduces the porosity of the aquifer in the neighborhood of the drill hole, whether by compaction of normally granular materials or by deposition of fine materials from a drilling fluid. Known methods for restoring and even increasing the porosity of the aquifer at the bottom of the well hole include over pumping, mechanical surging, and surging with air. The present invention related to provide an arrangement for providing well developing which is very cost effective, require less time and minimum human resources.
