Assignee:

AVA International Corporation - Houston TX

International Classification:

E21B 3410

US Classification:

166325

Abstract:

There is disclosed a subsurface tubing safety valve of the type having a flapper pivotally mounted in the bore of a tubular body disposable in a tubing string, and a flow tube vertically reciprocable within the bore of the body between an upper position permitting the flapper to close the bore and a lower position engaging and moving the flapper into a recess in the side of the bore to open the bore. The flow tube is yieldably urged to its upper position and moved to its lower position in response to the supply of hydraulic fluid from a remote source to a piston engageable with the flow tube, and the flapper is yieldably urged to its closed position by means of an arm pivotally mounted on the body for extension over the lower surface of the flapper and a spring providing a vertically extending force acting between an end of the arm to one side of its pivotal axis and the body to urge the arm to a position to close the flapper.

Abstract:

A method of analyzing an asset is provided. The method can include receiving first data characterizing an industrial asset. The first data can be acquired via a sensor. The method can also include determining a condition of the industrial asset based on a 3D digital twin of the industrial asset. The 3D digital twin can be generated using second data acquired prior to the first data. The digital twin can include at least one 3D digital instance of at least one component of the industrial asset and a list of components of the industrial asset described according to a pre-defined taxonomy associated with the industrial asset. The method can also include providing the condition of the industrial asset. Related apparatuses, systems, and computer-readable mediums are also provided.
