| A down hole apparatus for filtering debris from a fluid in a well bore including a screen sub, a diverter assembly connected to the screen sub, a screen section extending from the diverter assembly and connected to the screen sub. The screen section includes a plurality of openings for filtering debris from the fluid. The debris collects in an annulus between the screen section and the screen sub. The diverter assembly includes a detachable plug having a fishing portion capable of engaging a fishing tool. Removal of the detachable plug with a fishing tool opens a central passage through the diverter assembly and the screen section. The diverter assembly may include an outer and an inner body and one or more passages between the outer and inner bodies. The detachable plug may include one or more dog members capable of engaging the inner body. | ||||||

| A combination tool is delivered to compacted debris above a packer whose plug is to be removed. The shoe or mill is on the lower end of an outer bushing and the grapple or overshot is held within the bushing but away from the shoe so that the shoe can advance into the debris as reverse circulation takes the cuttings up through a mandrel to a debris removal tool. When the shoe lands on the packer the surface personnel can see it on the weight indicator. Weight is then set down to overcome a resisting force of a breakable member such as a shear pin or a spring or both so that the grapple advances to engage the packer plug. Advancing the mandrel relative to the bushing with the shoe at its lower end also releases a torque lug that previously allowed tandem rotation of the mandrel with the bushing. | ||||||

| Nanoemulsion, macroemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor I, II or III phase behavior) or single phase microemulsions (Winsor IV) improve the removal of filter cakes formed during hydrocarbon reservoir wellbore drilling with OBM. Such filter cakes and their particles can contact, impact and affect the movement of the drill string undesirably resulting in a “stuck pipe” condition. The macroemulsion, nanoemulsion, miniemulsion, microemulsion systems with excess oil or water or both or single phase microemulsion removes oil and solids from the filter cake, thereby releasing the drill string from its stuck condition. In one non-limiting embodiment, the emulsion system may be formed in situ (downhole) rather than produced or prepared in advance and pumped downhole. | ||||||

| The present invention relates to methods and equipment for recovering use of a well-bore in circumstances where the well bore has become blocked by downhole equipment. The invention provides a method comprising the steps of separating, at a release joint, a portion of equipment from a jammed portion (6) of equipment; running the separated portion of equipment uphole out of the wellbore (100); running a deflector assembly (60) downhole into the wellbore (100); and deflecting a milling tool (64) from the wellbore into surrounding formation. The method is characterised by restricting relative movement between the deflector assembly (60) and the wellbore (100) by engaging, prior to deflecting the milling tool (64), the deflector assembly (60) with said jammed portion (6) of equipment. | ||||||

| A safety sleeve used with a wireline connection where the safety sleeve comprises an elongated body with an axial aperture formed along its axis. The wireline connection connects a severed wireline and can be comprised of a fishing spear and a fishing overshot. The safety sleeve axially encompasses the wireline connection assembly with its elongated body. The bending moment required to yield said safety sleeve is greater than the maximum bending moment experienced by the combination of the safety sleeve and the wireline connection during operation. The safety sleeve can also include a collar threadedly connectable to one side of the elongated body, a window formed along the elongated body, and a raised portion formed on the inner radius of the elongated body.
