Abstract: A screen apparatus for use in a well bore. The apparatus comprises a latch; a first tubular disposed within the latch, the first tubular having an internal retrieving profile; a screen extending from the first tubular, and wherein the screen contains a first portion with a first outer diameter, and a second portion that extends to a second outer diameter, and wherein the first outer diameter is larger that than the second outer diameter. The apparatus further comprises a diverter device operatively attached to an inner portion of the first tubular, and wherein the diverter device contains a passage to divert the fluid to an outer portion of the screen. In one preferred embodiment, the screen comprises a series of longitudinal slots of progressively smaller length. Also, the screen may contain a stepped outer diameter portion and inner diameter portion. A method of cleaning debris is also included.

Abstract: A telescoping, adjustable length tool basket, particularly suitable for offshore operations in the oil and gas industry. A center section has four elongated, tubular corner members, joined by bottom and side members. At least one, and preferably two, wing sections comprise elongated inner corner members that are slidably disposed within the outer corner members. The wing sections can be moved inwardly and outwardly from the center section to adjust the overall tool basket length to accommodate the tool length. When adjusted to the desired length, a lock pin is inserted through aligned holes in at least one pair of outer and inner corner members, to lock the tool basket at the desired length. Inner and outer bushings are disposed in the annulus between the inner and outer corner members. Preferably the bushings are of a polytetraflouroethylene (PTFE) material such as Teflon®.

Abstract: An apparatus for controlling the flow of a medium. The apparatus comprises a base having a plurality of arms extending from the base. The base and arms define a cage. A valve member is positioned within the cage. The apparatus further includes a biasing housing disposed within the base, and wherein a spring is disposed within the biasing housing. The apparatus further includes a passageway formed about the valve member when the valve member is opened so that the medium flows on the outer portion of the biasing housing, and wherein the flow of the medium in an opposite direction urges the ball into engagement with the valve seat. When the valve is open, the medium collapses the spring and the valve member blocks the flow of the medium from entering the biasing housing. A method of drilling a well with the flow valve positioned on a work string is also disclosed.
