A technique facilitates greasing of valves on a well tree, e.g. a frac tree, according to a simple process which enables selected, individual valves to be greased when desired. In some applications, the greasing process may be automated and controlled via a greasing control system. According to an embodiment, a greasing system is connected with grease ports at a plurality of actuatable valves located in a well tree. The greasing system has a plurality of grease valves which may be associated with each of the actuatable valves, e.g. with each of the grease ports. A pump is used to pump grease to the grease valves and the grease valves are selectively actuated to open positions to provide controlled greasing of desired actuatable valves so as to remove debris from and to lubricate selected actuatable valves.

System and method for valve greasing in a well tree

A diverter valve assembly includes a diverter valve. The diverter valve includes a housing having an inlet, multiple destination outlets, and a subsequent diverter valve outlet. The diverter valve also includes a rotary element disposed within the housing. The rotary element has an inlet, one or more target destination outlets, and a subsequent diverter valve outlet. Furthermore, the inlet of the rotary element is fluidly coupled to the inlet of the housing, the subsequent diverter valve outlet of the rotary element is fluidly coupled to the subsequent diverter valve outlet of the housing, and the rotary element is configured to rotate to selectively fluidly couple the one or more target destination outlets of the rotary element to one or more respective destination outlets of the housing.

Diverter valve assembly

Fracturing fluid delivery systems having components with sacrificial liners or sleeves are provided. In one example, a fracturing system includes a flexible fracturing fluid conduit coupled to a wellhead assembly. The flexible fracturing fluid conduit includes a flexible body, a rigid end joined to the flexible body, and a bore extending through the flexible body and the rigid end for conveying fracturing fluid to the wellhead assembly. The flexible fracturing fluid conduit also includes a rigid sacrificial sleeve installed in the rigid end and within the bore. In another example, a fracturing system includes a fracturing fluid delivery apparatus coupled to a wellhead. The fracturing fluid delivery apparatus includes a pressure-containing component having a rigid body with a bore for conveying fracturing fluid. The pressure-containing component has a sacrificial liner provided through the bore along an interior surface of the rigid body. Additional systems, devices, and methods are disclosed.

Fracturing fluid delivery systems with sacrificial liners or sleeves

A fracturing fluid delivery system having a fracturing line with a flexible liner is provided. In one embodiment, a method includes moving a flexible polymeric liner through a bore of a fracturing line to a position in which the flexible polymeric liner extends along an inner wall of a flexible pipe body of the fracturing line. The method also includes securing the flexible polymeric liner in the bore of the fracturing line, such as by attaching the flexible polymeric liner to an opposing surface of the fracturing line. Additional systems, devices, and methods are also disclosed.
