A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.

A high-performance seafloor flexible oil storage system, solving the existing problems of high storage cost and difficult maintenance of crude oil in offshore oilfields, comprises, sequentially connected, an oil-water separator, a pressure pump, and an input riser extending downward below the sealevel; and a pipeline and multiple flexible oil storage tanks having the same structure with each communicated therewith through a control valve are arranged below the sealevel. One end of the pipeline is communicated with the input riser through a blocking valve and an input valve, and the other end further sequentially connected with an outlet booster pump, an output valve, and an output riser extending upwards above the sealevel and connected to a tanker through a cooler and an output pump. The flexible oil storage tank has a concrete counterweight connected thereunder for fixing it to a seabed. The system has simple structure, convenient maintenance and good practicability.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

A detection system for use with a pipeline network having a fluid flowing therethrough. The fluid contains an ingredient that deposits on the interior walls of the pipeline network. The detection system is interposed within the pipeline network and comprises a first fluid path and a second fluid path. A material is distributed throughout the interior of the second fluid path that is capable of inducing and accelerating the deposition of the fluid ingredient on the walls of the second fluid path. A sensor exposed to the second fluid path monitors changes in the path indicative of deposit build-up. The sensor communicates with a control system. The control system directs a chemical injector to introduce chemical inhibitors into the pipeline network to inhibit ingredient deposition on the walls of the pipeline network.
