Once your 2.0 in. screen is installed, you need to develop the well
properly. The new 2.0-in. Well Development Tool is equipped with a flexible
polyurethane collar to help surge water into and out of the screen during
the development process.
The development tool attaches to nominal 0.5-in.
PVC riser so it can be lowered into the well and efficiently raised and
lowered to surge and purge the well. Movement of water into and out of the
screen provides for better development and removal of fines around the
screened interval. A check valve in the tool allows you to purge water from
the well while surging to help remove the fines and provide for good
hydraulic communication between the well and formation.
It’s best to develop
segments of the screen and move up and down through the screen interval
repeatedly to achieve adequate development. Review ASTM Standard D 5521 for
additional guidance and information on well development techniques and
purposes.
