A well may be developed by surging, overpumping, jetting, and ______________.

• A. Backwashing
• B. Bailing
• C. Drilling
• D. Airlifting

Answer: (A)

Well development aims to restore and improve water entry by removing fines and sediment that clog the around-screen pore spaces. Surging, overpumping, and jetting physically disturb and dislodge material, but backwashing uses reverse-flow water to flush those loosened sediments and debris out of the well and screen. This cleaning of the screen and surrounding gravel pack helps reopen pathways for water to enter, increasing yield and well performance. Drilling is construction, and while bailing or airlifting can be used, backwashing specifically relies on reversing flow to clear accumulated material, making it the best choice here.
