“…Therefore, the sand production is indeed proportional to the flow rate under the Eqn ; that is, if we were to calibrate the model for a certain reference value of Q , then we can predict sand production for other values of the flow rate. In Papamichos et al , it is argued that this proportionality is supported (very) approximately by experiment. Nonetheless, considering the data of Papamichos et al in scaled time t / τ suggests that this is too approximate and possibly not entirely correct, in the sense that different Q curves (for the same external stress) do not visibly collapse to each other at an acceptable level.…”

“…The availability of models to predict the onset and quantity of sand produced is very crucial. There is a vast literature in the modelling of erosion phenomena attempting to capture the failure and onset of sanding . Sanding criteria that are routinely used in the models for predictions are usually based on shear, tensile failure critical pressure gradient , critical plastic deformation and erosion based criteria .…”

SUMMARYSand production is a complex physical process that depends on the external stress and flow rate conditions as well as on the state of the material. Models developed for the prediction of sand production are usually solved numerically because of the complexity of the governing equations. Testing of new sand production models can very well be performed through calibration with laboratory experiments, which by construction possess geometric symmetry facilitating explicit mathematical analysis. We introduce an erosion model that is built upon the physics (poro-mechanical coupling of the fluid-solid system) usually incorporated in erosion models for the prediction of sand production. Around this model, we set up a mathematical framework in which sand production models because of erosion can be tested and calibrated without having to resort to complex numerical work or specialised software. The model is validated by data of volumetric sand production from a hollow cylinder test on synthetic sandstone. Generalisations of the model, which are naturally incorporated in the same framework and have useful phenomenological features, are discussed. Copyright

“…In the second stage, after the end is de-sanded, the sand carrying fluid is pumped to increase the fracture width and finally improve the fracture conductivity (Yushi et al, 2021b). The tip screening out process is gradually formed on the basis of hydraulic fracturing technology, which artificially controls the fracture propagation and greatly increases the width of the fracture to achieve the purpose of both increasing production and sand control (Desroches and Thiercelin, 1993;Ortega L et al, 1996;Morita N et al, 1998). In unconsolidated sandstone reservoirs with high permeability, increasing fracture conductivity is more beneficial to increase production than increasing fracture length.…”

Sand production in oil wells seriously affects the production of oil and gas in oilfields. Although conventional sand-control techniques can effectively prevent sand production, it may also limit the productivity of oil wells. Fracturing and packing sand control technology changes the distribution of pressure and flow in the wellbore, while foam polymer resin diversion technology reduces the anisotropy of reservoir permeability and increases the area of oil leakage in the reservoir, both achieving the goal of sand control and increased production. The sand-free production rate is successfully increased thanks to zeta potential sand control technology, which modifies the formation’s sand potential and causes the sand to agglomerate without harming the reservoir. This article first looks into the causes of sand production in oil and gas wells before examining the fundamentals, implementation strategies, and effects of traditional sand control techniques, fracturing and filling sand control technology, foam polymer resin diversion technology, and Zeta potential sand control technology. In this article, the experience of sand control technology in actual oil field applications is summarized, explained in detail, and the future development possibilities of sand control technology are discussed.
