A single trip method of repairing a leaking annular seal located within an annulus that encircles an oil/as wellbore tubular body, examples of such seals including annular packers or cement seals. The method comprises providing deflector within a wellbore tubular body adjacent to one or more openings in the wall of the tubular body. Alloy beads are then deployed downhole via the tubular body so that the alloy beads are deflected via said openings into the annulus where they accumulate on top of the annular seal. The alloy is then heated to form an alloy plug above the annular seal. The present invention also provides an annular seal repair tool assembly for use in the repair method of the present invention.

A system includes a solids trap disposed in a well. The system includes an inner annulus, an outer annulus, and a chamber between the inner annulus and the outer annulus. A solids accumulation zone is formed in the chamber. A pump is fluidly connected to the solids trap. A fluid stream carrying solids flows from the pump. The fluid stream carrying solids is configured to follow a path delimited by the outer annulus and the chamber until the fluid stream deposits the solids in the solids accumulation zone and departs the solids trap via the inner annulus into a tubing.

The downhole tool comprises: (i) a housing connected with a collection chamber for receiving debris, the housing having an opening for collecting the debris from the petroleum well, the opening in fluid communication with the collection chamber through the housing; (ii) a rotatable shaft with transport blades arranged within the housing and extending from the opening to the collection chamber, the rotatable shaft configured for transporting debris from the opening to the collection chamber in operational use; (iii) an annular area defined between the rotatable shaft and an inner wall of the housing and (iv) a valve configured for keeping debris in the collection chamber. The valve is located within the housing between the opening and the collection chamber. The valve comprises a seal member with a movable part mounted in the annular area and around the rotatable shaft. The valve is opened when the movable part moves in direction of the collection chamber and is configured such that the movable part of the seal member is only movable in the direction towards the collection chamber when closed. The downhole tool provides a valve, which is easily opened, requiring a very small force, while providing a very good sealing effect when the seal member is closed.

This disclosure relates generally to pulling tools and, more particularly, to incorporating a bailer feature in pulling tools. A pulling tool may be provided that includes a housing. The pulling tool may further include a tool engagement assembly securing in the housing with a distal end of the tool engagement assembly extending from the housing for engagement with a well tool. The pulling tool may further include a bailer chamber formed in the tool engagement assembly and in fluid communication with an exterior of the pulling tool through an opening in the distal end of the tool engagement assembly. The pulling tool may further include a valve positioned in the opening of the tool engagement assembly.

A central shaft defines a first interior flow path. The central shaft disposed at least partially within a washover pipe. A lead tapered mill is positioned at a downhole end of the central shaft to center the downhole-type milling tool within a tubular. The lead tapered mill defines a second central flow path in line with the first interior flow path. Milling blades extend between the central shaft and the washover pipe. The milling blades are arranged to allow fluid flow around the milling blades. Each of the milling blades includes a tungsten-carbide hardened face and a soft steel body configured to support a load of the downhole-type milling tool during milling operations. A junk basket is positioned within the washover pipe uphole of the milling blades to receive and retain cuttings formed by the milling blades.

Embodiments of a debris catcher and a debris catching system are disclosed herein. In one embodiment, a debris catching system comprises a plug and a debris catcher, the debris catcher including at least a debris catching sleeve, a running tool coupled to the debris catching sleeve, the running tool including an uphole end and a downhole end, and further wherein the uphole end of the running tool is configured to slide to engage a downhole end of the debris catching sleeve and form a collection base of the debris catcher; and a coupling rod attached to the uphole end of the running tool, the coupling rod configured to engage a downhole setting device; wherein the plug is removably coupled with the downhole end of the running tool during downhole deployment of the debris catching system.
