Abstract: A cleaning apparatus for cleaning the inner surface of an oil or gas production tubing is disclosed. The cleaning apparatus includes a tubular body, one or more cleaning elements mounted on the outer surface of the body and an elastically deformable stabiliser. The elastically deformable stabiliser is rotatably mounted on the body to centralise the apparatus in the tubing whilst also allowing the body to pass though areas of reduced diameter in the production tubing. Preferably, there are a pair of spaced apart stabilisers having a web arrangement of spars with a flange at each end.

Abstract: A device for collecting debris from a well comprises a fluid injection conduit injecting circulating fluid into the area of the well to be treated, a fluid collection pathway for the recovery of fluid and suspended debris, and a collection chamber for the collection of debris suspended in the fluid. The collection pathway is helical, and typically the collection chamber is also helical. Typically, the boundary between the collection pathway and the helical collection chamber is defined by vanes, typically including a groove capable of forming a watertight seal with a sleeve fitting substantially over the device. Devices may include a baffle located above the uppermost edge of the helical collection pathway to direct matter into the collection chamber. Methods to the use of the device to collect debris from the well can include multiple devices, each adapted to collect debris of different sizes.

Abstract: The automated cage cleaning system is comprised of a pair of robotic arms, a soil side robot and a clean side robot. The soil side robot is utilized for removing the dirty cage bottoms from a cart, rack, pallet, or fixture, emptying soiled bedding from the cage bottoms, and placing the cage bottoms on a conveyer leading to the tunnel washing equipment. The clean side robot is used to grip the clean cage bottoms, and place the cage bottoms on a cart, rack, pallet, or fixture. Additionally, the present invention comprises an optical arranger robot with vision processing for detecting, and moving skewed cage bottoms to a re-grip station. From the re-grip station, the clean side robot places the cage bottoms on a rack, pallet, fixture, or any other device suitable for holding a plurality of cage bottoms.
