Abstract: An example mobile oilfield tool service center includes one or more intermodal containers, each intermodal container including a base, opposing sidewalls, opposing end walls, and a roof, and each intermodal container exhibiting a length, a width, and a height that are each compliant with a global containerized intermodal freight transport system. One or more service components are housed within the one or more intermodal containers for subjecting an oilfield tool to at least one process that repairs or rehabilitates the oilfield tool. A power source can be communicably coupled to the one or more intermodal containers to operate the one or more service components.

Abstract: Linear chain extended poly(alkylene oxides) having at least a portion of hydrophobic hydrogen bonding chain extending groups are soluble in at least one solvent and swellable in water. The chain extending groups preferably comprise a urea linkage and can be produced by the reaction of an amine with an isocyanate. The extended polymers and their solutions may readily be fabricated into controlled release compositions, e.g. for the release of pharmaceuticals.
