    1. Detailed information

    Casing Scraper

    Casing scraper is an internal tool used for removing obstructions or foreign material from inside the walls of casing, such as cement, rust, mud, bullets, paraffin, and perforation burrs, so as to make all downhole tools get unblocked.

    Below three types of tools can be used together to achieve maximum working efficiency.

     Casing Compensator

     MetInfo enterprise content manager system | MetInfo CMS

    Casing Compensator works as a connector when an old damaged casing needs to be replaced and removed out from down-hole, while a new casing needs to be put down. Patch are particularly well suited to service in wells which contain fluids and gases which are harmful to synthetic rubber packers. It’s designed to from a permanent sealed connection between two strings of tubing or casing and cement them together in a single run. The seals used are compression type, multiple lead rings, These casing patches are very simple to operate.

     FAC Tool

     MetInfo enterprise content manager system | MetInfo CMS

    Fill and Circulate Tool (hereafter referred to as FAC Tool) is a surface tool used during the casing running operation. The FAC Tool is designed to both fill the casing with drilling fluid while running it in the hole and to enable quick circulation of the casing string at any time without installation of a casing swage. The FAC Tool has features with easy –to- use , safe and reliable , no leakage and so on, which lightens labor intensity of workers greatly and improves operation environment of well.

    The FAC Tool may come in two tool sizes, Large (L-FAC) and Medium (M-FAC) so as to adapt different pipe diameter, different sizes may adapt pipe diameter at any size through changing seal assembly.
