The invention comprises, in one form thereof, a pump jack tree stand including a platform and a seat engaging a pump jack. The pump jack cooperates with a pole that is supported by an adjacent tree. The user actuates a foot lever on the pump jack to climb the pole. The pump jack's release is hand actuated as opposed to the commonly used foot-actuated release.

A game call assembly for attracting wild game comprises a game call configured for emitting a call when rotated to an inverted position. A motor when energized rotates a shaft. The game call is coupled to the shaft. A switch selectively electrically connects a power source to the motor. The game call assembly is configured for being mounted to a weapon, and also functions as a stabilizer.

An expandable well screen has a desirable thin-wall construction together with a simplified fabrication method. In fabricating the screen, a flexible sheet of metal mesh filter media is diffusion bonded to an inner side of a perforated metal sheet which is then deformed to a tubular shape to form a filter structure having an outer perforated tubular shroud interiorly lined with the filter media. The tubular filter structure is telescoped onto a perforated base pipe and has its opposite ends sealingly secured thereto to complete the expandable well screen.

Methods of completing a subterranean well

In a particle or sand screen control assembly for mounting on a base pipe used in a well, a sealing strip preferably in the form of a metal strip is used in a weld joint that joins the metal mesh screen of filter media to a solid metal structure or &ldquo;safe edge&rdquo;. The sealing strip covers the pores in the screen proximate the metal structure to which it is welded. The sealing strip is a separate thin sheet of metal that is compatible with the welding metal used in the weld joint, such that the sealing strip becomes unitary with the weld joint. Prior to welding, the sealing strip may be bent around the screen if desired, or may lie flat along the top or bottom surface of the screen.

Welded particle control screen assemblies

A particle control screen assembly for a perforated pipe used in a well, a sand filter system, and methods of making same are provided. The screen assembly includes a woven mesh filter media disposed about an inner surface of the perforated pipe, and a protective wrapper disposed about the filter media. The protective wrapper comprises a radially inner perforated layer and a radially outer layer that is disposed between the inner layer and the filter media. A surface of the outer layer that faces the inner perforated layer has a non-smooth contour, with this surface of the outer layer having portions in direct contact with an outer surface of the inner layer. The outer layer is provided with apertures that are disposed in such a way that fluid cannot flow from the inner surface of the inner perforated layer directly radially both through holes of the inner layer and through the apertures of the outer layer.
