A method for orienting well casing and other tubular work objects of differing transverse dimension relative to each other including the steps of positioning the work objects telescopically relative to each other in such a manner that when the work object of larger transverse dimension is disposed in a substantially vertical attitude, the work object of smaller transverse dimension is pendantly supported gravitationally substantially to self center along a common axis with the work object of larger transverse dimension; disposing the work object of larger transverse dimension in a substantially vertical attitude; and mounting the work objects in fixed relation relative to each other. A device including a member mounted within the work object of larger transverse dimension defining a first plane substantially right-angularly related to the longitudinal axis of the work object of larger transverse dimension and a member mounted externally of the work object of smaller transverse dimension defining a second plane substantially right-angularly related to the longitudinal axis of the work object of smaller transverse dimension.

A method and casing for a well in which the casing has a conduit formed by a substantially tubular wall defining an interior and an exterior for the conduit and having an opening extending through the wall to establish a path for fluid movement into the interior of the conduit, and a housing mounted on the exterior of the conduit having a chamber in communication with the opening of the conduit and the housing having an opening therein to establish a path for fluid movement into the chamber of the housing.

A flow control device for a fluid pump having a path for fluid flow therethrough substantially along a predetermined axis, the path having successive portions of reduced and enlarged size relative to each other substantially concentric to the axis, an impeller mounted for rotational movement within the portion of enlarged size to draw fluid along the path, the flow control device having a tubular member adapted to be mounted on the pump substantially coincident with the portion of reduced size and extending into the impeller for introducing the fluid flow thereto.

A bearing assembly for use in fluid pumps having a pump housing through which a pump drive shaft is extended for rotation about an axis of rotation, the bearing assembly including a pair of sleeves dimensioned to be fitted within the pump housing substantially concentric to the axis of rotation and about the drive shaft and spaced from each other to form an annular lubricant reservoir therebetween and about the drive shaft.
