“…CFD has been successfully used in various applications to assess erosion problems, including applications in the oil and gas industry such as erosion of surface and downhole piping systems (Shah and Jain, 2008;Clem et al, 2006, Brown 1999, Huser and Kvernvold 1998. In such investigations, the CFD models were used to perform flow and particle tracking analyses to: (1) determine locations where the piping or tool surfaces are impacted by sand particles; (2) quantify the impact speeds and impingement angles of the particles on the component surfaces; and (3) calculate the erosion rate where particles come in contact with the equipment.…”

High rate injection or production of fluids with sand particles places wellhead components and downhole assemblies at risk of erosion damage. Depending on the severity and location of the material loss, this may pose a significant well loss or blowout hazard. For this reason, assessment and mitigation of erosion can be critical for such applications.In this work, Computational Fluid Dynamics (CFD) was used in conjunction with erosion models to assess the erosion damage characteristics associated with the operating conditions and equipment for a high-rate, shale gas reservoir fracturing application. The work was based on the severe erosion damage experienced by EnCana as a result of high rate hydraulic fracturing operations performed in horizontal shale gas wells at their Horn River, BC field development. Material losses were observed within the wellhead equipment as well as in the LTC couplings of the production casing string near surface in several wells. CFD models were developed for the existing wellhead and wellbore geometries and used to simulate a range of hydraulic fracture operating conditions in an effort to predict the locations and degree of material loss in the components in each case. The models were calibrated with caliper log data and measurements taken from casing samples retrieved from several wells. The analyses suggested that well head system modifications, such as tubing head spool changes and use of spacer spools, could be effective in substantially reducing material losses in the tubular connections. In addition, sensitivity analyses were performed for different wellhead configurations and variations in the hydraulic fracturing parameters to determine the factors that likely had the most influence on the connection material losses. The results served to demonstrate that it is possible to use CFD with erosion models as predictive tools to identify locations of severe erosion in completion systems, and, when calibration data is available, to quantify the amount of material loss in wellhead and downhole components. This information can aid in designing optimum completions systems, and in defining operating conditions which can reduce the risk of equipment failure, potential blow-outs, and associated safety and environmental hazards.

ABSTRACT：Modeling and studying the impact behaviors of angular particles are critical in understanding the mechanisms of erosive wear on solid surfaces. This paper focuses on effective meshfree model based on the Smoothed Particle Hydrodynamics (SPH) method to simulate impacts of angular particles on metallic surfaces. The predicted results are compared with the available experimental data, and good agreements have been achieved. Our simulations under different incident conditions successfully reproduce the general impact behaviors of angular particles, including rotating behavior and rebound behavior, which enables detailed examinations of erosion mechanisms. We find that the rotating behaviors are mainly determined by initial orientation and impact angle, while impact velocity has little effect. For backward impact involving a prying-off action, there generally exsits a critical impact velocity below which the cutting process would never be finished, which may result in a rebound angle greater than 90°.

The results demonstrate the ability of present model on handling extremely deformed surface by overlapping impacts. The proposed SPH model and out present study could be useful in the study of erosive wear on the surface of metal devices that carries granular substances.
