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: 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.

Abstract: A nanozeolite modified green concrete contains alkali-activated natural pozzolan. Natural pozzolan is a green and sustainable material, potentially useful in green concrete, e.g., to curb greenhouse gas emissions associated with ordinary Portland cement production. Nanozeolite (NZ) is present as an additive to the green concrete, e.g., at 3 to 5 wt. %, of natural pozzolan to improve strength development and microstructural properties, resulting in superior strength and denser microstructure compared to a green concrete without nanozeolite.

Abstract: The system for measuring multi-phase fluid flow characteristics is an on-site system for measuring and calculating fluid density of a multi-phase fluid, such as a mixture of oil and water, as well as a water cut thereof. The system for measuring multi-phase fluid flow characteristics includes a conduit having a lower inlet and an upper outlet. The lower inlet is adapted for direct connection to an oil pipeline, an oil well, or the like for receiving the multi-phase fluid flowing therethrough. The conduit defines a pressure monitoring portion having opposing ends. First and second impulse lines connect first and second gauge pressure transmitters and a differential pressure transmitter to the opposing ends to measure total pressure drop and frictional pressure differential to an external controller, which calculates the fluid density and the water cut therefrom The system may also include temperature and volumetric flow rate sensors.
