Abstract
A snap-lock bushing is provided for use with prepacked screens for monitoring wells. The bushing has an inner bore for sliding over a tubular well casing member and a raised lip protruding from the inner bore for engaging corresponding grooves at each end of the well casing member. The raised lip includes a plurality of lip segments with gaps or slots formed between the lip segments, which allow the raised lip to flex outward during assembly. A prepacked screen is assembled using a snap-lock bushing at each end of the well casing member. A mesh screen is placed in a concentric relationship around the well casing member with the ends of the mesh screen secured over the outer cylindrical surfaces of the bushings. A filter pack of granular material is placed in the concentric space between the well casing member and the screen member during assembly.
