Systems, methods and apparatus using a solid chemical as an injectable for inhibiting, decreasing or preventing precipitation and/or deposition of foulants and/or contaminants in oilfield tubulars. The use of solid chemicals providing ease of shipment, greater economy in storage, shipment and delivery and increased ease of use.

Systems, methods, and apparatuses for treating petroleum in a container are disclosed herein. The method includes electrically heating a portion of the container to generate heat sufficient to create convection currents in the petroleum. The method also includes stopping heating after the petroleum cools below a threshold temperature. The systems, methods, and apparatuses mitigate yield stress in petroleum susceptible to gelling.

An electrical installation for an electrical system for trace heating a fluid transport pipe (8) made of metal, at least one polyphase circuit having three main electric cables (6-1, 6-4, and 6-7) in a star connection, and one additional electric cable (6-2, 6-3, 6-5, 6-6, 6-8, and 6-9), the main cables and the additional cable positioned around the pipe and connected at the pipeline end to a common connection ring (10) forming a point of zero electric potential, and detector for detecting a failure, if any, of the polyphase circuit to identify a failed main cable in order to replace it with the additional cable.

Disclosed is a spirally heating submarine pipeline including: a conduit which transports a high temperature high pressure fluid from a submarine oil well; and a heating unit disposed in a spiral structure inside based on an outer circumferential surface of the conduit. The heating unit includes an electric heating wire that is installed along the spiral structure to generate heat; a heat insulator that is installed in the form of fully surrounding the electric heating wire and preserves the generated heat; and a heat insulating cap for isolating the heat insulator from the conduit or the heat insulating layer and is provided so as to increase the temperature of the flow in the pipe to prevent the production of a pipe flow interfering material when the fluid is transported in the conduit.
