A treatment composition for use in treating production fluids in or from a subterranean formation is provided. The treatment composition can be used for viscosity control in subsea umbilical fluid delivery applications, wherein the treatment composition exhibits desirable viscosity, flash point and/or pour point values.

A ball drain wye strainer valve assembly includes a wye strainer located adjacent to a T-ball valve within a unitary body. The ball drain wye strainer valve assembly includes an additional valve member. The combination of the valve members permits the flushing of the wye strainer screen from either upstream or downstream. A drain is also incorporated to allow for the system draining, flushing, or air-purging during the initial installation and subsequent maintenance of the screen and wye strainer.

There is a formulation and a method for inhibiting carbon-based deposits on metal substrate. The method comprises the use of a formulation comprising at least one oxidizing agent and at least one etchant capable of forming free metal ions from the metal substrate, at least one sequestering agent having a ligand capable of forming a complex with the free metal ions and at least one chelating agent having a ligand capable of complexing with at least one surface metal atom.

Unique insulation articles including corrosion inhibitors and methods of producing the same are disclosed. One exemplary embodiment is an article of manufacture comprising an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first surface and a second surface, a veil attached to the first surface, the veil structured to inhibit physical movement of the cured combination through the veil, a metal sheet attached to the second surface by a water-containing adhesive contacting the metal sheet and the second surface, and a corrosion inhibitor composition deposited on the cured combination of the insulation mat, the corrosion inhibitor composition being effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive.

A support clip for attaching a fluid-carrying tube or line to a substrate is disclosed that provides an air tight seal on a single fluid-carrying tube or line or on multiple fluid-carrying tubes or lines when the tubes are secured between two different surfaces. The support clip has two mated elastomeric surfaces defined by upper and lower halves that account for minor surface-to-surface variations while still maintaining an air tight seal. The lower half is attached to a substrate in a vehicle by a locating anchor. Each half has a rigid body and an elastomeric portion. The rigid body maintains the form of the elastomeric portion. At least one tube-holding channel is formed in the elastomeric portion of each of half. When the two halves are fastened together by an interference fit, the air tight seal is established. The halves may be fastened together by a variety of mechanical arrangements.
