Which methods are used to develop wells that are air rotary drilled?

• A. Air surging
• B. Backwashing
• C. Pumping
• D. All of the above

Answer: (D)

Developing an air rotary drilled well focuses on removing fines and debris and establishing a clean, permeable flow path around the screen so the well can produce efficiently. Air surging uses rapid air pressure changes to loosen and eject fines from around the screen and in the borehole, helping to clear the passageways so water can move more freely into the well. Backwashing introduces clean water down the casing to push water up through the screen and gravel pack, carrying loosened particles with it and cleaning the screen openings. Pumping physically removes water along with suspended solids from the well, aiding in removing remaining fines and conditioning the formation to sustain a better, more stable yield. Because each method addresses different aspects of cleanliness and flow in air rotary wells, they are commonly used in combination or sequence to achieve effective development. So all of these approaches are employed in developing air rotary drilled wells.
