To properly develop 2‐inch diameter monitor wells, large volumes of water, drilling fluids and fine‐grained materials must be removed from the sandpack and surrounding formation over short periods of time. A valved and air‐vented surge plunger has been designed which can be used to effectively develop 2‐inch diameter wells. The valving and air‐venting concepts for surge plungers are not new, but the design concepts had to be refined to facilitate their efficient use in 2‐inch diameter wells. Prototypes of the surge plunger have been field tested. The tests indicate that the design is both effective and durable as a result of its dimensions, configurations and materials. Important features of the surge plunger include: the dimensions and weight of the surge block; the thickness, layering, diameter and material of the valves and parts; and the method of attachment and design of the air‐venting ports. This device is an important addition to the growing arsenal of equipment and tools for 2‐inch diameter, standpipe monitoring wells.
