Assignee:
Kejr Inc. - Salina KS
International Classification:
E21B 43/34
US Classification:
166228, 175314
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.
Mechanical Bladder Pump
US Patent:

Assignee:
Kejr, Inc. - Salina KS
International Classification:
F04B043/00, F04B039/10
US Classification:
417472, 417478, 4175552, 166264
Abstract:
A mechanical bladder pump is provided for collecting fluid samples from a well. The pump includes an outer tubular member having a longitudinal bore, and an inner tubular member arranged within the bore of the outer tubular member. The inner and outer tubular members are connected at their lower ends to a compressible bladder, and are arranged for oscillating movement relative to each other to expand and compress the bladder. The lower end of the bladder is open to an inlet passage, and the upper end of the bladder is open to an outlet passage. First and second check valves are provided to control the flow of fluid through the bladder during operation of the pump. A return spring is used to store energy during a tension stroke of the inner tubular member and to release energy during a compression stroke thereof. The pump provides highly representative samples of groundwater.
