Abstract: A downhole hydra-jetting apparatus has a substantially cylindrical guide housing having an outer surface and an inner surface, and defining a cavity longitudinally extending through the guide housing; a plurality of retractable guide members attached radially around the guide housing; and a substantially cylindrical jet housing having an outer surface and an inner surface, and defining a cavity longitudinally extending through the jet housing, with a plurality of jetting nozzles defined in, and radially positioned about, the jet housing. Each of the plurality of jetting nozzles are adjustable relative to the guide housing to allow substantial alignment of projections from the plurality of jetting nozzles and the plurality of guide members when the guide members are extended radially from the outer surface of the guide housing and the apparatus is actively moved through a downhole.

Abstract: A basketball system having has a ballasted base, an adjustable support system comprising two pole sections, a backboard, a hoop structure, and a net. They include an upper pole section and a lower pole section, and may be operated either telescopically or non-telescopically. The base has a first socket that receives the lower pole section, and a second socket is sized to receive the upper pole section when the system is operated in the non-telescoping mode. The hoop structure is provided with a neck flange for attaching the hoop structure to a recess in the upper telescoping pole section. The net is attached to the hoop structure by a net retention hoop on which the net is threadedly engaged.
