A method of activating an anchor with an anchor activation system including a housing having an outer surface and an inner surface defining an internal chamber includes introducing a first activation force to a trigger comprising a piston arranged in a piston cylinder extending radially through the outer surface to the internal chamber, sensing that the first activation force did not activate the anchor, and introducing a second activation force to the trigger without reconfiguring the anchor activation system to break a shear element retaining the piston with the first activation to release the piston and activate the anchor

A scale sampler plunger having an upper end and a downhole end for a plunger lift system in a tubing string comprising: a solid cylindrical member at the upper end of the scale sampler plunger configured to remove a plurality of contaminants in the tubing string; a lower sub at the downhole end of the scale sampler plunger threaded to the solid cylindrical member, wherein the lower sub comprises a first section threaded to a second section extending axially from the first section; wherein a fluid stream carrying solids flows from the tubing string into an entry opening located in the second section; a deflector disposed in a chamber in the lower sub, wherein the deflector causes the fluid stream carrying solids to deposit the solids in the chamber in the lower sub; and an anchor disposed in the entry opening, wherein the anchor is fastened to the deflector.

A method of activating an anchor with an anchor activation system including a housing having an outer surface and an inner surface defining an internal chamber includes introducing a first activation force to a trigger comprising a piston arranged in a piston cylinder extending radially through the outer surface to the internal chamber, sensing that the first activation force did not activate the anchor, and introducing a second activation force to the trigger without reconfiguring the anchor activation system to break a shear element retaining the piston with the first activation to release the piston and activate the anchor.

A downhole cleaning apparatus (10) comprising a tubular body (12). The tubular body (12) comprises comprising a plurality of openings (20) therethrough. Each opening (20) defines at least part of a helix extending longitudinally and circumferentially about the tubular body (12). The downhole cleaning apparatus (10) also includes a plurality of cleaning elements (22). Each cleaning element (22) is configured to extend through an opening (20) and to extend outwards from an outer surface of the tubular body (12). The cleaning elements (22) are distributed about the tubular body (12) and each cleaning element (22) defines at least part of a helix extending longitudinally and circumferentially about the tubular body. The openings (20) and the cleaning elements (22) are grouped to define a plurality of substantially continuous helical paths (18). Each helical path (18) extends substantially end to end of the tubular body and the helical paths (18) are distributed relative to each other to define a cleaning surface of at least 360 degrees.

An anchor activation system including a housing having an outer surface, an inner surface defining an internal chamber, a first end, and a second end. A slip is shiftably mounted to the outer surface of the housing. The anchor activation system also includes a piston assembly and an activator mounted to the piston assembly. The activator selectively shifts the slip axially along the housing. A biasing member is arranged between the second end and the activator. A trigger is operable to selectively release the piston assembly.

Disclosed embodiments include an apparatus, such as a plunger for oil and/or gas wells, that includes one or more scraping features. The scraping feature may include at least one ridge configured to scrape material, such as paraffins, asphaltenes, salt, hydrates, debris, solids, etc., from an inner surface of a tubular body and direct the scraped material away from the plunger body. A disclosed method for scraping material from a tubular body includes releasing a plunger within the tubular body, the plunger having a body with an outer surface and a scraping feature on the outer surface that includes at least one ridge; scraping material from an inner surface of the tubular body with the ridge of the scraping feature; and directing the scraped material away from the plunger body.
