Abstract: A method and apparatus for retrieving magnetic casing fragments from a well using a shrouded magnet are disclosed. Retrieving casing fragments allows the determination of weight loss from the casing to assist in analyzing the integrity of the casing and to determine whether more expensive analysis is required. The shrouded magnet, a non-magnetic container enclosing a source of magnetic field, recovers metal casing fragments, which fragments are easily separated from the device by removing the source of magnetic field from the container.

Abstract: A method and apparatus for retrieving magnetic casing fragments from a well using a shrouded magnet are disclosed. Retrieving casing fragments allows the determination of weight loss from the casing to assist in analyzing the integrity and the condition of the casing and to determine whether more expensive analysis is required. The shrouded magnet, that is formed by a non-magnetic container enclosing a source of magnetic field, recovers metal casing fragments by attracting them and other magnetic materials from oil and gas well fluids passing by the shrouded magnet device, which fragments are easily separated from the device by removing the source of magnetic field from the container.

Abstract: A garden structure includes a plurality of adjacent plastic base members with each of the base members including a frame portion, a filler portion, a sealing portion and a fastening portion. The frame portion includes spaced substantially flat major sections, sections having substantially the same configuration and being disposed substantially parallel to each other. Sidewall sections extend between adjacent peripheral edges of the major sections and at least two opposed sidewall sections are substantially parallel to each other throughout their lengths. The spaced major sections and sidewall sections together form a cavity within the base member. The filler portion includes particulate material compressed within the cavity of the base member and filling same. The sealing portion includes an opening in one sidewall of the base member and a cover section engageable with and completely enclosing the opening.
