Showing papers on "Annulus (oil well) published in 2022"

TL;DR: In this paper, a multiphysics routine for calculating annular pressure buildup (APB) in vertical oil wells is proposed, which couples three key aspects influencing the occurrence of APB: (i) the flow of heated hydrocarbons through the well production tubing, which is accounted for with a multi-component, two-phase hydrodynamic model, (ii) a radial, resistance-based thermal model, which determines the multi-modal heat transfer between the production tubing and the surrounding formation, and (iii) a mechanical model which, when coupled to the previous

TL;DR: In this article, an oil-based annulus protection fluid was developed to prevent casing corrosion in a gas-injection well of CO2 flooding, which is composed of white oil and 1000mg/L imidazoline inhibitor.

TL;DR: In this article, the impact of three operational parameters on cuttings transport in non-Newtonian drilling fluids was analyzed using Computational fluid dynamics (CFD) simulations.

TL;DR: In this paper, the effect of the gas-liquid fluid flow pattern within the annulus on cuttings transport was investigated and the results showed that both fluid flow patterns and the drilling fluid flow rate are the most influential controllable parameters that affect the cut-ings transport efficiency, and the degree of its effect is highly dependent on the fluid properties, the cutting transport mechanism and prevailing gas liquid flow pattern.
