摘要： A milling and wellbore metal recovery assembly includes a milling assembly that can mill a casing disposed in a wellbore. A primary debris removal assembly is connected to the milling assembly and can reside uphole of the milling assembly. The primary debris removal assembly can clear debris resulting from the milling assembly milling the casing disposed in the wellbore by reverse circulating wellbore fluid in an uphole direction from an annulus formed by the wellbore and through the primary debris removal assembly. A second debris removal assembly is connected to the primary debris removal assembly, and can reside uphole of the primary debris removal assembly. The secondary debris removal assembly can clear debris resulting from the milling assembly milling the casing by circulating wellbore fluid in a downhole direction through the secondary debris removal assembly and then in the uphole direction through the annulus towards a surface of the wellbore.

摘要： A well tool assembly includes a first well tool and a second well tool. The first well tool includes a first casing, a first drill bit and a drilling jar. The first drill bit is configured to drill through a subterranean zone to form a wellbore. The drilling jar is axially coupled to the casing uphole of the first drill bit. The drilling jar has an outer diameter that is greater than an outer diameter of the first casing. The second well tool has a second casing and a second drill bit. The second casing has an outer diameter that is smaller than an inner diameter of the drilling jar. The second drill bit has an outer diameter that is smaller than the inner diameter of the drilling jar.

摘要： An apparatus includes a scale removal head, a scale collector, a circulating plate assembly, and a guide. The scale removal head includes a plurality of blades that scrape against a wall of a wellbore to remove scale from the wall of the wellbore in response to rotation of the apparatus. The scale collector defines a first inner region within a surrounding slotted chamber. The circulating plate assembly defines a second inner region within a pipe. The first inner region and the second inner region together define a collection volume for accumulating and storing scale that has been removed from the wall of the wellbore. The guide includes a plurality of blades that scrape against the wall of the wellbore to remove scale from the wall of the wellbore as the apparatus rotates.

摘要： An exposed resistive heating element is coupled to an electric power supply. The exposed resistive heating element is malleable such that it can be wrapped around a component to be heated. A controller is coupled to the power supply and the exposed resistive heating element. The controller is configured to regulate current exchanged between the exposed heating element and the electric power supply.
