Study on deposit formation model in sulfide-containing natural gas environment

Journal of Petroleum Exploration and Production Technology, 2022
The breathing pipe of a produced water storage tank in a sulfide-containing natural gas station is prone to deposit formation, which leads to pipeline blockage. In this study, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS),

Study of Chelating Agent—Surfactant Interactions on the Interphase as Possibly Useful for the Well Stimulation

Energies, 2023
Chelating agents’ application for EOR and well stimulation is fast growing nowadays. However, reagents of this class have some drawbacks, with high values of interfacial tension (IFT) being among them. IFT may be lowered with the addition of surfactants;

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

Advanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

Advanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.

PHASE BEHAVIOR OF GAS-CONDENSATE FLUIDS DURING WELL TESTING

Известия высших учебных заведений: Нефть и газ, 2015
Hydrodynamic studies in gas-condensate wells allow determining the features of fluids flow in the gas condensate reservoir by build-up curves. A variation in the shape of the build-up curve may reflect a behavior of fluids in the reservoir, that is the ...

A new approach to improving efficiency of gas-lift wells in the conditions of the formation of organic wax deposits in the Dragon field

Journal of Petroleum Exploration and Production Technology, 2020
Gas-lift is one of the artificial methods in which gas is injected down the production casing–tubing annulus and enters the production tubing through a number of gas-lift valves. During the production of a gas-lift well, the injected compressed gas might
