摘要： A well, such as a natural gas well, may be treated to increase production of gas by inserting into the tubing string a water soluble carrier containing a well treating chemical adapted to aerate fluids standing in the tubing string. The dissolvable carrier contains a compressed swab adapted, upon dissolution of the carrier, to expand to fill the diameter of the tubing string, and well treating chemicals adapted to aerate the standing fluid in the well above and below the swab. The presence of the aerating fluids in the well lighten the hydrostatic head, permitting a plug of fluid above the swab to be displaced from the well as the swab is urged upward due to pressure exerted on the swab by the formation and by the aerating effect of well treating chemicals released below the swab. The dissolvable materials for the carrier preferably are selected so that the carrier will not dissolve until it has reached a seating nipple near the lower end of the tubing string, thus assuring that the maximum slug of fluid is displaced from the well bore above the swab.

摘要： Pickup stick assemblies suitable for picking up objects and discharging the retrieved objects into a trash or other receptacle may include an assembly housing having a proximal housing end and a distal housing end. A spring retaining member may be disposed between the proximal housing end and the distal housing end. An assembly shaft may be slidably disposed in the assembly housing. The assembly shaft may have a proximal assembly shaft end protruding beyond the proximal housing end of the assembly housing and a distal assembly shaft end opposite the proximal assembly shaft end. The assembly shaft may be deployable in an extended shaft position in which the distal assembly shaft end protrudes beyond the distal housing end of the assembly housing and a retracted shaft position in which the distal assembly shaft end is recessed with respect to the distal housing end of the assembly housing. A shaft retention spring may be provided in the assembly housing. The shaft retention spring may engage the spring retaining member and the assembly shaft to normally bias the assembly shaft in the extended shaft position. At least one object retaining member may be provided on the assembly shaft at the distal assembly shaft end.
