Abstract: A two-phase liquid-gas flow system for testing electrical submersible pumps (ESP) includes an oil pump, a water pump, an oil storage tank, a water storage tank, a pressurized air system, an air pressure regulator (PR), and a transparent test section with the ESP. The pressurized air system includes air storage tanks, compressors, and air flow meters (AFM). The oil pump and the water pump supply oil and water from the oil storage tank and the water storage tank through an oil flow meter and a water flow meter, respectively, to the transparent test section. The air storage tanks are in fluid communication with the PR by valves, which channel air through the PR and the AFMs to the transparent test section. A camera is provided to capture photos and videos of flow patterns of the working fluid in the transparent test section.

Abstract: A multiphase flow calibration semi-closed loop system includes an oil-gas-water separation unit, a multiphase flow calibration unit, a single phase flow calibration section, a gas flow section, a flow data acquisition unit, and a programmable logic controller (PLC). The system is designed to have a two-step calibration process. In a first step, single phase water flow meters and single phase oil flow meters of the system are calibrated independently. In a second step, multiphase flow meters or multiphase water cut meters are calibrated using the pre-calibrated water flow meter, pre-calibrated oil flow meter, and the pre-calibrated gas flow meter. In doing so, the oil-gas-water separation unit, the multiphase flow calibration unit, the single phase flow calibration section, and the gas flow section communicate with the flow data acquisition unit providing real time data. Thus, the PLC connected to the flow data acquisition unit can perform the required calibration processes.

Abstract: A structural, load-bearing panel useful in constructing multistory buildings may have a panel height, panel width, and panel thickness, and may include a first layer comprising at least 75 wt. % of concrete, relative to a total weight of the first layer; an insulation layer comprising flexible polymer, the insulation layer having a thickness of at least 5 cm; and a second layer comprising at least 75 wt. % concrete, wherein the insulation layer is sandwiched between the first and second layers, and wherein the panel is suitable to be set in any of a planar, curved, and polyhedral cross-sectional shape. Set panels are not flexible, though the flexibility of the insulation layer, particularly of a polyethylene foam, may allow the panel to have a curved, or polyhedral cross-section while still serving as a structural support.

Abstract: A system, device, and a method for determining a compound content in transformer oil are provided. The method includes positioning a syringe filled with transformer oil in the device to transfer the oil to a vial using the device. The device includes a stand, a threaded rod, a handle, a disc, and a syringe holder. The threaded rod is movable in a vertical direction by rotation of the handle and is configured to apply pressure via the disc on a plunger of the syringe positioned in the syringe holder to maintain an airtight connection between the vial and the device. The compound content is determined using a gas chromatograph by analyzing an aliquot extracted from a headspace gas of the vial.

Abstract: The operational performance of pumps can be improved when pumping liquids with at least 10 vol. % gas volume fraction (GVF) as found in many oil fields, wherein wells produce mixtures of gas and oil in varying proportions. An increase in the GVF that would have led to slugging in the flow, degrading the performance of pump in multiphase flow loop, and would have necessitated a check valve at each fluid stream to avoid flow reversal, can be overcome by a multiphase flow loop including a solenoid valve on the gas stream, which maintains the same intake gas pressure as that of oil/liquid pressure during the experiments. By testing pumps at more accurate GVFs, pump performance can be better assessed, resulting in reduced power consumption and increased efficiency.
