Problems solved by technology

One challenge in maintaining fluid communication through the perforations is that the size of the perforations (aperture size or aperture diameter) in the wellbore casing sections begins to change as the edges erode.
These erosions introduce uncertainties in otherwise contro

Abstract

Aspects of the disclosed technology provide techniques for facilitating hydrocarbon extraction from a wellbore. In some aspects, the disclosed technology encompasses a novel casing string that includes at least one casing section, an aperture disposed on a surface of the casing section, and an insert affixed around a periphery of the aperture. The casing string can further include a plug disposed within the insert, wherein the plug is configured to be selectively removable to allow fluid communication between an interior volume of the casing string and an exterior of the casing string, e.g., adjacent to a geologic formation.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally solutions for preventing erosive enlargement of fluid communication holes in a wellbore casing and in particular, to the fitting of casing perforations with wear-resistant inserts to protect against erosion and ensure consistent perforation aperture size.BACKGROUND[0002]To obtain hydrocarbons such as oil and gas, wellbores are typically drilled by rotating a drill bit that is attached at the end of the drill string. Modern drilling systems frequently employ a drill string having a bottom hole assembly and a drill bit at an end thereof. The drill bit is rotated by a downhole motor of the bottom hole assembly and / or by rotating the drill string. Pressurized drilling fluid is pumped through the drill string to power the downhole motor, provide lubrication and cooling to the drill bit and other components, and carry away formation cuttings.[0003]A large proportion of drilling activity involves directional drilling, e.g., dril...
